Opinion issued July 2, 2024
In The
Court of Appeals For The
First District of Texas ———————————— NO. 01-24-00005-CV ——————————— RAOUF HANNA, DDS AND HANNA DENTAL IMPLANTS, LLLP, Appellants V. THOMAS NEIL TURNER, Appellee
On Appeal from the 295th District Court Harris County, Texas Trial Court Case No. 2023-29015
MEMORANDUM OPINION
This accelerated interlocutory appeal arises from a suit for dental malpractice.
Thomas Neil Turner sued his dentist, Raouf Hanna, and Hanna’s practice, Hanna
Dental Implants, LLLP, alleging negligent placement of implants. As required by
the Texas Medical Liability Act, Turner timely served an expert report, and later a timely supplemental expert report, regarding the standard of care, its breach, and
proximate cause. Hanna objected that the reports were inadequate in all three
respects. The trial court ultimately overruled Hanna’s objection. Hanna appeals.
We affirm.
BACKGROUND
Turner’s Petition
In his live pleading, Turner alleges that Hanna assured him he was a good
candidate for dental implants after performing a single, limited evaluation. A month
later, Hanna extracted all of Turner’s remaining teeth, 27 in total, and installed
several implants. Within a month or so afterward, Turner reported that his lip
sometimes tingled and some liquids ran out of his nose when he drank. Hanna
reassured Turner that he was still in the process of healing from the procedure, but
also indicated that he would evaluate the possibility that there was a problem.
According to Turner, he continued to complain about the liquids issue during
subsequent office visits. Each time he was reassured that he was still healing, either
by Hanna or one of Hanna’s employees, and Turner relied on these reassurances.
Several years later, after continued problems that included constant sinus
infections and severe headaches, Turner sought emergency treatment for respiratory
problems, neck pain, and swollen lymph nodes. While being treated for these
2 conditions, Turner learned for the first time that dental screws implanted in his jaw
by Hanna were protruding into his nasal passageway and his left maxillary sinus.
Turner then sued Hanna and Hanna’s dental practice for negligence. Among
other things, Turner alleges that Hanna did not perform proper diagnostic imaging
before removal of his teeth and installation of implants or after the procedure;
properly assess the bone depth of his jaw before or after the procedure; or recognize
and correct complications that developed after the procedure and caused Turner’s
injuries, including nasal perforations, sinus perforations, and nerve damage.
Due to his injuries, Turner further alleges, all his dental implants must be
removed. In addition, Turner has required extensive other medical treatments, and
his treatments to repair the injuries caused by Hanna remain ongoing. At least one
injury, certain nerve damage, is irreparable and cannot be undone by treatment.
Expert Report
With his petition, Turner served Hanna with an expert report made by Alan L.
Rosenfeld, DDS. When Rosenfeld made his report, he had been a practicing dentist
for almost fifty years. As his qualifications are not in dispute, we do not dwell on
them in detail. Among other things, however, Rosenfeld is a certified specialist in
periodontics, the branch of dentistry focused on the gums and jawbone, and he has
placed thousands of dental implants during his career. For more than three decades,
3 Rosenfeld has used computed tomography scans—often referred to as CT or CAT
scans—to aid him in the diagnosis and treatment planning of dental implants.
Rosenfeld summarizes the treatment Turner received from Hanna over the
course of a little more than three years. When he first came into Hanna’s care, Turner
was in his early 60s. Turner’s chief complaint concerned past dental work and his
desire for a permanent solution to dental issues. Rosenfeld notes that Hanna initially
performed a “limited evaluation” that did not include “an assessment of the integrity
of existing dental restorations” and included a single panoramic x-ray. Though
Hanna’s treatment plan was “complex, aggressive, and not reversible,” Rosenfeld
observes that the entire initial visit was “completed in approximately one hour.”
A month after the initial visit, Hanna removed all 27 of Turner’s remaining
teeth and installed nine implants: five in the upper jaw and four in the lower jaw.
At follow-up visits during the next month, Turner complained that his lower
lip tingled sometimes and some liquids exited through his right nostril when he drank
them. Rosenfeld notes that there was no record that Hanna assessed these
complaints. Instead, Turner was told that he needed to heal, and that the possibility
of communication between the mouth and nose would be addressed if necessary.
In the next several months, there were multiple follow-up visits. As
documented in Turner’s dental records, these visits primarily concerned the
fabrication, construction, and installation of the final prostheses and their
4 maintenance. This was followed by a nine-month period in which Turner did not see
Hanna. Rosenfeld states that this gap in treatment may be related to the Covid-19
pandemic but that Turner should have been seen by Hanna during this period.
At a later visit, a little under a year and half after the initial removal of Turner’s
teeth, Hanna removed the upper jaw prosthesis in order to adjust it to improve lip
support. In the process, Hanna observed an oroantral fistula, which is an abnormal
communication or connection between the mouth and the sinus in the upper jaw.
Apparently, this issue was noted in Turner’s records more than a year beforehand.
Rosenfeld states that though entries “suggest this was addressed previously,” “no
assessment of maxillary sinus health was entered into the patient record.”
About a month later, another dentist at Hanna’s practice saw Turner for a
complaint that he felt a clicking or movement while chewing. The dentist determined
“that component looseness existed.” It is unclear what treatment, if any, was given.
Almost five months afterward, Turner visited Hanna’s practice for implant
maintenance. Among other things, it was noted that he had acute mucositis, a
condition involving pain and inflammation of the mucous membranes. In two later
visits, six months and ten months after the initial one when acute mucositis was
observed, it was again noted that Turner continued to suffer from this condition.
Just over three years after the initial procedure, Turner went to the emergency
room of Memorial Hermann Hospital. His complaints included a month-long runny
5 nose, strep throat treated with two rounds of antibiotics, neck pain severe enough to
preclude driving, severe headache the previous day, swollen lymph nodes, and
shortness of breath. A CT scan was performed. Among other things, the scan showed
that three dental screws protruded into the nasal passageway, one dental screw was
embedded in the septum, and at least one dental screw protruded into the left sinus
of the upper jaw. A second dental screw possibly protruded into this sinus as well.
It was recommended that Turner seek treatment from an ear-nose-throat
specialist and infectious disease specialist. Turner did so. He also saw a periodontist,
who recommended that Turner see an oral and maxillofacial surgeon for treatment.
Turner did so, and the surgeon concluded that all the implants in Turner’s upper jaw
would have to be removed, nasal and sinus fistulas would need surgical repair, and
the nerve injury was permanent and would not improve with implant removal.
The surgeon removed the upper jaw implants. When he removed one of them,
the left posterior implant, there was pus (liquid produced in infected tissue). Upon
removal of the other ones, the surgeon noted a foul odor from the nasal cavity.
Turner has continued to experience problems afterward and has required
additional treatment for a reoccurring sinus infection and sinus inflammation.
Based on Turner’s medical history, Rosenfeld concludes that Hanna violated
the standard of care in several ways. Rosenfeld opines that the standard of care
required Hanna to make a comprehensive evaluation of Turner’s teeth before
6 deciding whether extraction and replacement with implants was warranted,
including the use of full-mouth periapical x-rays (an x-ray that images the entire
tooth and supporting bone) and three-dimensional imaging. Hanna did not do so.
Similarly, Rosenfeld states that the standard of care required Hanna to use
three-dimensional imaging after the removal of Turner’s teeth and placement of
implants to assess potential complications from the procedure. Hanna did not do so.
Rosenfeld further opines that the standard of care required Hanna to vigilantly
monitor Turner for nasal and sinus perforations after the placement of the implants
in the upper jaw. But Hanna failed to recognize, assess, and correct these problems.
In addition, Rosenfeld states that the standard of care required Hanna to
vigilantly monitor Turner for nerve injuries after the placement of the implants in
the lower jaw. Unless promptly identified and corrected, these injuries can become
permanent. Hanna failed to verify the correct placement of the lower jaw implants
and failed to recognize Turner’s nerve injury and take corrective measures, including
the immediate referral to a doctor specializing in the treatment of nerve injuries.
Rosenfeld also faults Hanna for failing to alter the prosthetic treatment plan
in the face of inadequate implant support and biomechanical prosthetic failures,
develop a prosthetic design that would allow for personal and professional hygiene
maintenance, and create an adequate process for disclosure and informed consent.
7 As to causation, Rosenfeld opines that when Turner first visited Hanna, there
was no evidence he was in pain or had loose teeth, cavities, or functional limitations.
Nor was there any evidence that the problems that Turner developed after Hanna
removed his teeth and installed implants resulted from lack of patient compliance.
Had Hanna not breached the standard of care, Rosenfeld concludes, the injuries and
damages Turner sustained would more likely than not have been avoided.
Hanna’s Objection
Hanna objected to Rosenfeld’s report. He argued that the report was
conclusory as to the standard of care and breach. Specifically, Hanna contended that
Rosenfeld failed to explain what Hanna should have done differently. He also argued
that the report was conclusory as to causation in that it lacked the information
necessary to explain how any breach caused Turner’s alleged injuries or damages.
Trial Court’s First Ruling
The trial court held a hearing, after which it issued a written order overruling
Hanna’s objection as to the standard of care and its breach. But the trial court
sustained Hanna’s objection as to Rosenfeld’s causation opinion, and it ordered
Turner to serve a sufficient expert report regarding causation within 30 days.
Supplemental Report
Turner served Hanna with a supplemental report made by Rosenfeld. In his
supplemental report, Rosenfeld opines that Hanna’s breaches caused Turner to
8 become an “oral invalid,” meaning that Turner experienced complete failure of the
upper jaw prosthesis and a complete loss of the normal ability to chew. When Turner
first came to see Hanna, Turner did not complain of pain, swelling, or lack of
function. Turner had no tooth decay or functional deficit at that time. After being in
Hanna’s care, Turner wears an upper denture plate and has impaired chewing.
More specifically, Rosenfeld opines that Hanna should have foreseen that his
failure to comply with the standard of care pertaining to evaluation and imaging
would result in the failure to detect existing bone deficiency in Turner’s upper jaw
and result in a corresponding failure to plan for the lack of sinus floor bone there.
Had Hanna undertaken the necessary evaluation and imaging, he could have altered
his treatment plan to take this bone deficiency into account. Or, alternatively, Hanna
could have advised Turner of the corresponding risks and recommended against the
use of implants. These failures caused Turner to become an “oral invalid.” And, had
Hanna simply done nothing at all, Turner would be better off than he is today.
Rosenfeld further opines that Hanna’s violations of the standard of care
resulted in Turner having less jawbone than he had before Hanna treated him.
Turner’s bone loss was increased by infection and the removal of the implants.
In sum, Rosenfeld concludes that Turner’s injuries and damages, the latter of
which includes the medical expenses required to treat Turner’s injuries, would have
been avoided altogether if Hanna had not violated the standard of care. In particular,
9 Rosenfeld states that the perforation of Turner’s nasal and sinus cavities by dental
screws and the insertion of a screw into his nerve would not have occurred had
Hanna used periapical x-rays and three-dimensional imaging. Hanna’s failure to do
so likewise resulted in Hanna failing to correct these complications during the
approximately three-year period in which Hanna continued to treat Turner afterward.
Hanna’s Renewed Objection
Hanna objected to Rosenfeld’s supplemental report. He argued that
Rosenfeld’s supplemental causation opinions lack the required degree of specificity
and explanation. Hanna maintained that Rosenfeld’s opinions remain conclusory by
failing to explain how and why Hanna’s alleged breaches of the standard of care
caused Turner’s injuries and damages. Hanna further argued that Rosenfeld did not
adequately link his causation opinions to the underlying medical facts of the case.
Trial Court’s Second Ruling
The trial court overruled Hanna’s renewed objection to Rosenfeld’s opinion.
DISCUSSION
Hanna contends the trial court abused its discretion in ruling that Rosenfeld’s
initial and supplemental reports together satisfied the Texas Medical Liability Act.
Hanna maintains that Rosenfeld’s initial report does not adequately identify the
applicable standard of care or explain how Hanna breached this standard. Hanna
further maintains that Rosenfeld’s supplemental report is inadequate as to causation.
10 Standard of Review
We review a trial court’s ruling regarding the adequacy of an expert report
served on a physician or health care provider under the Texas Medical Liability Act
for an abuse of discretion. Baty v. Futrell, 543 S.W.3d 689, 693 (Tex. 2018). Under
this standard, we consider only the information within the four corners of the report.
Abshire v. Christus Health Se. Tex., 563 S.W.3d 219, 223 (Tex. 2018) (per curiam).
Applicable Law
A trial court may grant a motion challenging the adequacy of an expert report
“only if it appears to the court, after hearing, that the report does not represent an
objective good faith effort to comply with the [Act’s] definition of an expert report.”
Baty, 543 S.W.3d at 693 (quoting TEX. CIV. PRAC. & REM. CODE § 74.351(l)); see
also TEX. CIV. PRAC. & REM. CODE § 74.351(r)(6) (defining “expert report” as one
that gives fair summary of opinions on standard of care, breach, and causation).
To satisfy this standard, an expert report need not marshal all the claimant’s
proof. Baty, 543 S.W.3d at 693. But the report cannot be conclusory. Id. It must
discuss the standard of care, breach, and causation with enough specificity to inform
the physician or health care provider of the conduct that the claimant calls into
question and supply a basis for the trial court to find the claim has merit. Id.
The standard of care consists of what an ordinarily prudent physician or health
care provider would do under the same or similar circumstances. Am. Transitional
11 Care Ctrs. of Tex. v. Palacios, 46 S.W.3d 873, 880 (Tex. 2001). Thus, an expert
report must identify a specific act the physician or health care provider was required
to perform or refrain from performing, and explain how he or she failed to fulfill his
or her duty. See Baty, 543 S.W.3d at 694–95 (holding general statement that care
should have been provided “in the proper manner” to avoid injury was conclusory
and inadequate and advising that adequate report must explain what defendant
should have been done differently). If the standard of care or its ostensible breach
can only be inferred from the expert report, the report is inadequate. See Palacios,
46 S.W.3d at 880 (reasoning that expert report was so vague it might have
encompassed multiple unspecified complaints—closer monitoring, securer restraint,
or something else—and therefore was too conclusory in nature and inadequate).
With respect to proximate causation, an expert report must identify “how and
why” a breach of the standard of care caused the injury, harm, or damages by
explaining the basis for the expert’s statements and linking his conclusions to
specific facts. E.D. ex rel. B.O. v. Tex. Health Care, 644 S.W.3d 660, 664 (Tex.
2022) (per curiam). The report need only explain how, as a factual matter, the
claimant will prove causation. Id. Whether the expert’s opinion is credible or
believable is not relevant to the question of whether his report is adequate. Id.
Talismanic words and phrases are not required. Baty, 543 S.W.3d at 693. An
expert report does not need to use legal terminology, like “proximate cause,”
12 “foreseeability,” or “cause in fact.” Columbia Valley Healthcare Sys. v. Zamarripa,
526 S.W.3d 453, 460 (Tex. 2017). Regardless of the exact language used, however,
the report must explain, factually, how the claimant is going to prove the physician
or health care provider proximately caused the injuries, harm, or damages. Id.
In evaluating the adequacy of an expert report, we read the report as a whole.
E.D. ex rel. B.O., 644 S.W.3d at 667. The report can be informal. Palacios, 46
S.W.3d at 879. The information in the report does not have to satisfy evidentiary
requirements that will be applicable on summary judgment or at trial. Id.; see also
E.D. ex rel. B.O., 644 S.W.3d at 667 (reiterating that adequacy is not evidentiary
standard and that expert report need not litigate merits as prerequisite to suit).
Analysis
Standard of Care and Breach
Hanna asserts that Rosenfeld’s reports are conclusory as to the standard of
care and its breach. Though Rosenfeld criticizes the care Hanna provided, Hanna
maintains that Rosenfeld does not explain what Hanna should have done instead.
We disagree with Hanna. Among other things, Rosenfeld opines that Hanna
should have used full-mouth periapical x-rays and three-dimensional imaging before
removing Turner’s teeth and installing implants in his upper and lower jaws.
Rosenfeld further opines that Hanna should have used three-dimensional imaging
after this procedure, given the signs of complications that Turner soon displayed,
13 which included tingling in the lower lip, liquids running out of his nose when he
drank, instability in one of the upper jaw prostheses, and a litany of health issues.
Rosenfeld also explains why the standard of care required Hanna to use full-
mouth periapical x-rays and three-dimensional imaging. Apart from identifying
whether Turner had enough jawbone to support this procedure at the outset of
treatment and thus was a suitable patient for the placement of implants, the use of
full-mouth periapical x-rays and three-dimensional imaging afterward would have
revealed that dental screws had perforated Turner’s nasal passageway and a sinus
cavity and struck a nerve. These problems could have then been timely addressed.
In short, Rosenfeld specifically identifies what Hanna should have done
differently. This is all that is required with respect to identifying the standard of care
and its breach at this point in the case. See Baty, 543 S.W.3d at 694–95 (explaining
that expert must identify specific act physician or health care provider was required
to perform or refrain from performing and explain how he or she failed to do so);
see also Harvey v. Kindred Healthcare Operating, 578 S.W.3d 638, 652–53 (Tex.
App.—Houston [14th Dist.] 2019, no pet.) (holding that expert report adequately
stated standard of care and its breach in specifying health care providers should have
taken daily x-rays to verify proper placement of chest tube but failed to do so);
Richter v. Downey, 565 S.W.3d 847, 855 (Tex. App.—Austin 2018, no pet.)
(concluding that expert report adequately identified applicable standard of care and
14 its breach by specifying that physician should have ordered CT scan for patient
presenting with possible signs of acute appendicitis but failed to order scan).
Rosenfeld opines that Hanna violated the standard of care in a variety of other
ways. But having found his opinions concerning full-mouth periapical x-rays and
three-dimensional imaging adequate, we need not address other ostensible breaches.
See Miller v. JSC Lake Highlands Operations, 536 S.W.3d 510, 516 n.7 (Tex. 2017)
(per curiam) (stating court need not consider all standards of care articulated in report
after concluding others are adequate); TTHR Ltd. P’ship v. Moreno, 401 S.W.3d 41,
45 (Tex. 2013) (holding suit could proceed against hospital because expert’s report
was adequate as to one theory of liability asserting vicarious liability for agents’ acts
and need not address other agents); see also TEX. R. APP. P. 47.1 (requiring opinion
to be as brief as practicable while deciding all issues necessary to dispose of appeal).
We hold that the trial court did not abuse its discretion in concluding that
Rosenfeld’s expert report is adequate as to the standard of care and its breach.
Accordingly, we overrule Hanna’s issue as to the standard of care and its breach.
Proximate Cause
Hanna asserts that Rosenfeld’s reports fail to explain how Hanna’s breaches
of the standard of care caused Turner’s injuries. Hanna likewise says that Rosenfeld
does not explain why different care would have resulted in a better outcome.
15 We again disagree with Hanna. Among other things, Rosenfeld opines that if
Hanna had used full-mouth periapical x-rays and three-dimensional imaging before
and after the removal of Turner’s teeth and placement of implants, dental screws
would not have perforated Turner’s nasal passageway and sinus cavity or struck a
nerve. Or, at the very least, Rosenfeld maintains that Hanna would have discovered
these injuries sooner, which would have allowed for their timelier treatment. In other
words, Rosenfeld opines that but for the failure to properly x-ray and image Turner
before and after the procedure, Turner’s injuries either would have been avoided
altogether or his suffering would have been of lesser duration or severity.
In this regard, Rosenfeld’s causation opinion is akin to the expert report our
supreme court found adequate in Baty. There, the essence of the expert’s opinion
was that the standard of care mandated that a nurse anesthetist not puncture the optic
nerve with the needle when administering anesthesia, the nurse anesthetist breached
this standard by puncturing the optic nerve with the needle, and the nurse anesthetist
caused permanent loss of vision in the eye as a result. Baty, 543 S.W.3d at 694–98.
The supreme court concluded that no more detail than this was required. See id.
The same is true here. To satisfy the Texas Medical Liability Act’s expert-
report requirement with respect to causation, the expert need only explain “how and
why” a particular breach of the standard of care caused the injury, harm, or damages
and link his explanation to specific facts. E.D. ex rel. B.O., 644 S.W.3d at 664.
16 Rosenfeld opines that Hanna’s failure to use full-mouth periapical x-rays and three-
dimensional imaging either resulted in the perforation of Turner’s nasal and sinus
cavities and piercing of his nerve or prolonged and exacerbated Turner’s injuries by
allowing these particular injuries to go undiagnosed for years. Rosenfeld connects
these opinions to specific facts. He relies on imaging showing the placement of the
dental screws and records of subsequent care and treatment as evidence of these
injuries, and relies on the signs and symptoms Turner reported to Hanna as evidence
that these injuries existed immediately after and as a result of the procedure in which
Hanna removed all of Turner’s teeth and replaced them with dental implants. This
is enough to satisfy the Act. See Owens v. Handyside, 478 S.W.3d 172, 187–91 (Tex.
App.—Houston [1st Dist.] 2015, pet. denied) (concluding expert report was
adequate as to causation by explaining failure to perform cerebral imaging resulted
in delay in diagnosis and care that would have prevented patient’s vision loss);
Adeyemi v. Guerrero, 329 S.W.3d 241, 244–46 (Tex. App.—Dallas 2010, no pet.)
(holding expert report was adequate as to causation in explaining that failure to order
CT scan or other imaging in face of patient’s repeated complaints resulted in delay
in diagnosis and care that caused patient’s seizure and other brain-related injuries).
To the extent Hanna argues more factual detail or specificity is required, we
disagree. Rosenfeld merely has to explain how, as a factual matter, causation will be
proved. E.D. ex rel. B.O., 644 S.W.3d at 664. In his supplemental report, he did so.
17 Likewise, to the extent that Hanna argues Rosenfeld’s report is inadequate because
he had to account for the fact that dental screws may perforate nasal and sinus
cavities or pierce a nerve even when a dentist uses various kinds of imaging, we
disagree. At this preliminary stage of the litigation, Turner and his expert are not
required to refute potential defenses or litigate the merits. See id. at 667 (reiterating
that expert report need not litigate merits of claims to be adequate under Act); Curnel
v. Houston Methodist Hosp.-Willowbrook, 562 S.W.3d 553, 562 (Tex. App.—
Houston [1st Dist.] 2018, no pet.) (stating expert does not have to anticipate or rebut
defensive theories defendant might assert in response to his causation opinion).
As we have found Rosenfeld’s opinions concerning full-mouth periapical x-
rays and three-dimensional imaging adequate, including on the issue of proximate
causation, we need not address whether his causation opinions concerning other
ostensible breaches of the standard of care are also adequate. See Moreno, 401
S.W.3d at 45 (holding suit could proceed against hospital because expert’s report
was adequate as to one theory of liability asserting vicarious liability for agents’ acts
and need not address other agents); see also TEX. R. APP. P. 47.1 (requiring opinion
to be as brief as practicable while deciding all issues necessary to dispose of appeal).
We hold that the trial court did not abuse its discretion in concluding that
Rosenfeld’s supplemental expert report is adequate with respect to causation.
Accordingly, we overrule Hanna’s issue regarding Rosenfeld’s causation opinion.
