Effect of Gender-affirming Facial Feminization Surgery on Psychosocial Outcomes.

OBJECTIVE: This study investigates the effect of gender-affirming facial feminization surgery (FFS) on psychosocial outcomes in patients with gender dysphoria. BACKGROUND: Comprehensive analyses of psychosocial outcomes after gender-affirming FFS are absent in the literature resulting in a paucity of information on the impact of FFS on quality of life as well as ramifications in health insurance coverage of FFS. METHODS: Scores from 11 validated, quantitative instruments from the Patient-Reported Outcomes Measurement Information System (PROMIS) assessing anxiety, anger, depression, global mental health, global physical health, satisfaction with sex life, positive affect, emotional support, social isolation, companionship, and meaning and purpose. Patients within the preoperative group (pre-FFS) were evaluated >30 days before surgery and patients within the postoperative group (post-FFS) were evaluated ≥10 weeks after surgery. RESULTS: A total of 169 patients [mean (SD) age, 33.5 (10.8) years] were included. Compared with the pre-FFS group (n=107), the post-FFS group (n=62) reported improved scores anxiety (56.8±8.8 vs 60.1±7.9, P =0.01), anger (47.4±7.6 vs 51.2±9.6, P =0.01), depression (52.2±9.2 vs 57.0±8.9, P =0.001), positive affect (46.6±8.9 vs 42.9±8.7, P =0.01), meaning and purpose (49.9±10.7 vs 46.2±10.5, P =0.03), global mental health (46.7±7.6 vs 43.1±9.2, P =0.01), and social isolation (52.2±7.5 vs 55.4±7.4, P =0.01). Multivariable analysis to account for the effects of other gender-affirming surgeries, hormone therapy duration, preexisting mental health diagnoses, socioeconomic disparities, and patient-reported quality of social relationships on psychosocial functioning demonstrated that completion of FFS was independently predictive of improved scores. CONCLUSIONS: Gender-affirming FFS improves the quality of life by multiple psychosocial domains in transfeminine patients.

Incidence and Outcomes of Laryngeal Complications Following Adult Cardiac Surgery: A National Analysis.

Laryngeal complications (LCs) following cardiac operations contribute to increased morbidity and resource utilization. Using a nationally representative cohort of cardiac surgical patients, we characterized the incidence of LC as well as its associated clinical and financial outcomes. All adults undergoing coronary artery bypass grafting and/or valvular operations were identified using the 2010-2017 Nationwide Readmissions Database. International Classification of Diseases 9th and 10th Revision diagnosis codes were used to identify LC. Trends were analyzed using a rank-based, non-parametric test (nptrend). Multivariable linear and logistic regressions were used to evaluate risk factors for LC, and its impact on mortality, complications, resource use and 30-day non-elective readmissions. Of an estimated 2,319,628 patients, 1.7% were diagnosed with perioperative LC, with rising incidence from 1.5% in 2010 to 1.8% in 2017 (nptrend < 0.001). After adjustment, female sex [adjusted odds ratio 1.08, 95% confidence interval (CI) 1.04-1.12], advancing age, and multi-valve procedures (1.51, 95% CI 1.36-1.67, reference: isolated CABG) were associated with increased odds of LC. Despite no risk-adjusted effect on mortality, LC was associated with increased odds of pneumonia (2.88, 95% CI 2.72-3.04), tracheostomy (4.84, 95% CI 4.44-5.26), and readmission (1.32, 95% CI 1.26-1.39). In addition, LC was associated with a 7.7-day increment (95% CI 7.4-8.0) in hospitalization duration and $24,200 (95% CI 23,000-25,400) in attributable costs. The present study found LC to be associated with increased perioperative sequelae and resource utilization. The development and application of active screening protocols for post-surgical LC are warranted to increase early detection and reduce associated morbidity.

The Incidence of Dysphagia Among Patients Undergoing TAVR With Either General Anesthesia or Moderate Sedation.

OBJECTIVES: To determine the incidence of dysphagia and aspiration pneumonia following transcatheter aortic valve replacement (TAVR) performed with either general anesthesia (GA) or moderate sedation (MS). DESIGN: Retrospective study. SETTING: Tertiary care university hospital. PARTICIPANTS: One hundred ninety-seven patients undergoing TAVR from 2012 to 2016 INTERVENTIONS: After Institutional Review Board approval, 197 consecutive patients undergoing TAVR from 2012 to 2016 at the authors' institution were identified for analysis and placed into groups depending on method of anesthesia received (GA: n = 139 v MS: n = 58). Groups then were compared with respect to baseline characteristics, operative details, primary outcome variables (dysphagia, pneumonia), and secondary outcome variables. MEASUREMENT AND MAIN RESULTS: Any patient who failed the institution's postprocedure bedside swallow test subsequently underwent a fiberoptic endoscopic evaluation of swallowing test, confirming the diagnosis of dysphagia. GA patients were significantly more likely to develop dysphagia, which occurred in 10 GA patients and no MS patients (p = 0.04). MS patients also were found to have significantly reduced operative durations and spent less time in the intensive care unit and hospital (p < 0.001). CONCLUSIONS: Patients who underwent TAVR with moderate sedation were less likely to develop dysphagia. Use of MS may be particularly suitable in patients predisposed to swallowing dysfunction.

Transoral Robotic Surgery Total Laryngectomy.

OBJECTIVE: The aim of our study is to demonstrate our technique for performing transoral robotic surgical total laryngectomy (TORS-TL) with the use of the da Vinci robotic system. MATERIALS AND METHODS: We provide a comprehensive description of the TORS-TL operative techniques. Two fresh-frozen human cadavers were selected after ethics approval to describe the appropriate step-by-step surgical resection. We adopted a 5-step procedure that was later applied to 2 of our patients. The first patient presented initially with a squamous cell carcinoma (SCC) in the laryngeal glottis area. A lack of clinical response to initial treatment by chemoradiotherapy led to the decision of performing salvage TL surgery. The second patient had a previous history of head and neck SCC (HNSCC); he had no recurrence of his primary tumor but suffered significantly from postoperative breathing and swallowing difficulties due to severe laryngeal incompetence. RESULTS: TORS-TL was successfully performed in all cases. The operative time for the cadavers was approximately 65 and 55 min, respectively. It was significantly longer for the patients, 210 and 235 min, respectively, despite the fact that exactly the same steps were followed throughout all procedures. There were no intra- or postoperative complications or surgical morbidity related to the use of the da Vinci system. CONCLUSION: TORS-SL for SCC was performed in a safe, reliable, and smooth manner and was shown to be successful in treating our patients. We thus believe that our step-by-step surgical technique for TORS-SL is efficient and reproducible.

Laryngeal oncocytic cystadenomas masquerading as laryngoceles.

OBJECTIVE: To describe an experience with laryngeal oncocytic cystadenomas and review the published literature regarding this uncommon diagnosis. METHODS AND RESULTS: A clinical review of patients presenting with cystic laryngeal masses in an urban academic medical center between January and December 2013 was performed. Three patients, two female and one male, with a mean age of 68 years, were diagnosed with oncocytic cystadenomata of the larynx. Major presenting symptoms included dysphonia, globus, and ipsilateral otalgia. Endoscopic examinations revealed a cystic structure arising from varied subsites of the larynx: laryngeal ventricle, aryepiglottic fold, and pre-epiglottic space. Cross-sectional radiographic imaging was obtained in each case. The patients were treated with transoral (CO2) laser microsurgery (TLM). In all three cases, pathological analysis revealed oncocytic cystadenoma with clear margins. CONCLUSIONS: Oncocytic cystadenoma is a rare entity of the larynx predominantly affecting elderly patients. Clinical presentation and imaging may suggest the diagnosis of an internal laryngocele. Complete excision is both diagnostic and therapeutic, and typically can be achieved using TLM. When clear margins are obtained, no adjuvant therapy is indicated. Although laryngoceles and malignancies are more commonly encountered, oncocytic cystadenomas should remain in the differential of cystic laryngeal masses.

A comparative study of cricotracheal resection and staged laryngotracheoplasty for adult subglottic stenosis.

OBJECTIVE: Cricotracheal resection (CTR) and laryngotracheoplasty (LTP) are open surgical treatments for severe subglottic stenosis. This study aims to compare the applications and outcomes of these techniques. METHOD: Patients with subglottic stenosis at a tertiary academic institution from 2000 to 2012 were identified by diagnosis codes. Patients who underwent LTP or CTR were included. Records were reviewed for treatment data and outcomes. Patients with a history of head and neck malignancy or stenosis without cricoid involvement were excluded. RESULT: Sixty-one and 20 patients underwent LTP and CTR, respectively. When comparing patients receiving LTP and CTR, there was a significant difference in stenosis etiology (P=.014). The groups were similar in Cotton-Myer grade (P=.102). At last follow-up, 80.3% of LTP patients and 90.0% of CTR patients were decannulated. On multivariate analysis, there was a significant association between stenosis grade and decannulation in the LTP group (P=.01). Decannulation was not associated with stenosis grade in the CTR group. In both groups, there was no significant association between decannulation and sex, stenosis etiology, or stenosis length. CONCLUSION: Cricotracheal resection and LTP have both shown excellent long-term decannulation rates. Etiology and stenosis grade are likely to be determining factors when recommending specific surgical interventions for subglottic stenosis.

Acute vocal fold dystonic reaction to propofol: a case report.

A 67-year old male underwent uneventful robotic-assisted thoracoscopic resection of a solitary pulmonary fibrous tumor. Immediately following extubation at the completion of the surgical procedure, the patient developed respiratory distress that did not resolve with treatment. Benadryl provided only temporary relief. Midazolam and hydromorphone were given for anxiolysis and analgesia respectively, which provided transient relief of symptoms. Propofol was given to decrease upper airway reflexes. Adequate reversal from nondepolarizing neuromuscular blockade was confirmed with nerve stimulator. A flexible laryngoscope was introduced nasally to visualize the vocal cords, which revealed intermittent tremulousness of the vocal cords, adduction of bilateral vocal cords to the midline, and minimal to absent opening with inspiration, without any apparent injury or blood, saliva, or vomit noted in or around the glottic opening. The patient was then given diazepam and reintubated. Given the patient's history of difficulty breathing after previous surgery and the lack of vocal cord movement, dystonic reaction to propofol was suspected. The patient remained intubated for two hours in the post-anesthesia care unit before being extubated uneventfully.

CO2 laser cordectomy for glottic squamous cell carcinoma involving the anterior commissure: voice and oncologic outcomes.

Transoral CO2 laser cordectomy for squamous cell carcinoma (SCC) of the glottis has resulted in excellent voice and oncologic outcomes as compared with non-surgical therapy. However, published experience with primary CO2 laser cordectomy specifically for glottic SCC involving the anterior commissure (AC) is limited. A review of single academic institution experience with CO2 laser cordectomy for glottic SCC involving the AC. Patients undergoing European Laryngological Society (ELS) classification cordectomy type Va or type VI between 2005 and 2013 were included. Post-surgical voice analysis was performed by speech language pathologists (SLP) from the reporting institution. Thirty patients were identified for inclusion. Mean post-surgical follow-up time was 47.6 months (range 11-59). Initial local recurrence was identified in 5/30 (16.7%) patients. 2/5 recurrences were successfully salvaged by repeat CO2 laser resections, 2/5 ultimately required salvage total laryngectomy, and 1/5 patient developed a second primary preventing further curative treatment. Overall laryngeal preservation rate was 28/30 (93.3%). Overall survival of the study cohort was 96.7%. Mean postoperative voice handicap index-120 score was 36.9 (SD = 21.4). Perceptual analysis performed on the GRBAS scale resulted in mean scores: G = 2.1 (SD = 0.9), R = 1.3 (SD = 1.1), B = 1.6 (SD = 1.2). Though cancers involving the AC represent an aggressive subgroup of glottic SCC, CO2 laser cordectomy results in encouraging oncologic and voice outcomes without the need for further therapy in the majority of cases. Clinical trials are encouraged to further define optimal treatment recommendations for glottic SCC involving the AC.

Utility of TTMV-HPV DNA in resolving indeterminate findings during oropharyngeal cancer surveillance.

OBJECTIVES: Clinical and imaging examinations frequently have indeterminate results during cancer surveillance, which can lead to overtreatment and cause psychological and financial harm to the patient. This study addresses the critical need to enhance diagnostic precision and decision-making in the management of HPV-associated oropharyngeal cancer. This study evaluated the utility of tumor tissue-modified viral (TTMV)-HPV DNA to resolve indeterminate disease status following definitive treatment for HPV-associated oropharyngeal cancer. MATERIALS AND METHODS: In this retrospective cohort, patients treated for HPV-associated oropharyngeal cancer at eight U.S. institutions and who received one or more TTMV-HPV DNA tests during post-treatment surveillance between February 2020 and January 2022 were included. RESULTS: Among 543 patients, 210 patients (38.7%; 210/543) experienced one or more clinically indeterminate findings (CIFs) during surveillance, with 503 CIFs recorded. Of those patients with an "indeterminate" disease status at a point during surveillance, 79 were associated with contemporaneous TTMV-HPV DNA testing. TTMV-HPV DNA testing demonstrated high accuracy (97.5%; 77/79) in correctly determining recurrence status. Patients whose disease status was "indeterminate" at the time of a positive TTMV-HPV DNA test were clinically confirmed to recur faster than those whose disease status was "no evidence of disease." Only 3% of patients (17/543) experienced indeterminate TTMV-HPV DNA tests during surveillance. Discordance between TTMV-HPV DNA tests and clinical results was minimal, with only 0.6% (3/543) of patients showing positive tests without recurrence. CONCLUSION: Our findings support the utility of circulating TTMV-HPV DNA in resolving indeterminate disease status and informing the subsequent clinical course.

Neuromuscular induced phonation in a human ex vivo perfused larynx preparation.

Considering differences in laryngeal anatomy, degree of control, and range of voice qualities between animals and humans, investigations of the neuromuscular process of voice control are better conducted using a living human larynx in which parametric stimulation of individual laryngeal muscles is possible. Due to difficulties in access and monitoring of laryngeal muscle activities, such investigations are impossible in living human subject experiments. This study reports the recent success in developing an ex vivo perfused human larynx model, which allows parametric muscle stimulation and observation of its influence on phonation of a virtually living human larynx in a well-controlled laboratory environment.

Evaluation and application of CO2 laser fiber delivery for single port transoral robotic surgery.

BACKGROUND: Transoral robotic surgery (TORS) using the Single-Port system (SPS) relies on electrocautery, limiting its applications in the upper aerodigestive tract. We evaluated the feasibility of a CO2 delivery system for the SPS. METHODS: Otolaryngology residents performed a cutting exercise using a handheld CO2 laser and participated in a cadaveric oropharyngeal dissection using the SPS with monopolar cautery (SP + EC) and CO2 laser (SP + CO2 ). Residents completed the System Usability Scale (SUS) questionnaire to evaluate these techniques. RESULTS: The same laser fiber was used for all combined dissections. The handheld CO2 laser, SP + EC, and SP + CO2 demonstrated similar SUS scores. On individual domain scores, SP + CO2 received less favorable ratings compared to the handheld CO2 laser for complexity, integration, and cumbersome experience (p < 0.05). On subgroup stratification, less TORS experience was associated with worse SUS scores. CONCLUSION: SP-guided CO2 laser delivery is a viable alternative to electrocautery in robotic surgery, and should be considered when performing TORS.

Laryngeal cancer treatment decision making: A conjoint analysis of general public attitudes and priorities.

Objective: Patients with advanced laryngeal cancer are typically presented with divergent treatment options, namely chemoradiation versus total laryngectomy. This study aims to understand general perspectives of the factors involved in this decision-making process. Methods: Surveys were constructed using specialized conjoint analysis software. Seven attributes integral to the decision-making process for advanced laryngeal cancer treatment were included. Results: Three hundred one healthy adult volunteers completed the decision-making program. The relative impact of each treatment attribute on decision making across all participants was scored with an average importance score (standard deviation) as follows: Lifespan 22.2% (±8.5), Voicing 21.4% (±5.9), Swallowing 19.1% (±7.3), Cancer Cure 14.9% (±6.2), Mode of Breathing 11.0% (±3.7), Self-Image 6.7% (±2.9), and Treatment Type 4.8% (±3.0). Conclusions: General public opinion ranked lifespan, voicing, and swallowing aspects as similarly important, and all were ranked more important than probability of cure. These data demonstrate a variety of priorities among participants and the need for tailored discussions when determining treatment choice for advanced laryngeal cancer. Level of Evidence: Level 4.

Adoption of otolaryngologist-head neck surgeons toward transoral robotic surgery: An international survey.

Objective: To investigate perception, adoption and awareness of otolaryngologist-head neck surgeons (OTO-HNS) toward transoral robotic surgery (TORS). Methods: An online survey was sent to 1383 OTO-HNS on the perception, adoption and awareness about TORS to members of many otolaryngological societies. The following aspects were assessed: TORS access; training; awareness/perception; indications and advantages/barriers to TORS practice. The responses were presented for the entire cohort and regarding the TORS experience of OTO-HNS. Results: A total of 359 completed the survey (26%); including 115 TORS surgeons. TORS-surgeons carry out a mean number of 34.4 annual TORS procedures. The primary barriers to TORS were the cost of the robot (74%) and disposable accessories (69%), and the lack of training opportunity (38%). The 3D view of the surgical field (66%), the postoperative quality of life outcomes (63%) and the shorter hospital stay (56%) were the most important benefits of TORS. TORS-surgeons believed more frequently that TORS is indicated for cT1-T2 oropharyngeal and supraglottic cancers than non-TORS surgeons (p < .005). Participants believed that the priorities for the future consisted of the reduction of the robot arm size and the incorporation of flexible instruments (28%); the integration of laser (25%) or GPS tracking based on imaging (18%), all of them to improve accesses to hypopharynx (24%), supraglottic larynx (23%) and vocal folds (22%). Conclusions: The perception, adoption and knowledges toward TORS depend on the access to robot. The findings of this survey may help guide decisions on how improve the dissemination of TORS interest and awareness.

Morphometric Analysis and Observer Perceptions Following Transvestibular Chondrolaryngoplasty.

OBJECTIVES: To assess novel morphometric measurement strategies and observer perception ratings as potential metrics for evaluating gender-affirming transvestibular chondrolaryngoplasty in reducing contour protrusion of the neck. METHODS: High-resolution preoperative and 3-month postoperative photographs of a pilot series of 10 patients (n = 10) who underwent endoscopic transvestibular chondrolaryngoplasty were collected. Morphometric measurements of "light reflex" and lateral view thyroid protrusion angles of the neck contours were analyzed. Pre- and postoperative photographs were presented in random order in a survey to 17 untrained judges and rated on perceived masculinity/femininity and thyroid notch protrusion on a 7-point scale. A pre- to postoperative change in morphometric angles and subjective ratings was assessed using paired t-tests and Wilcoxon signed-rank tests. RESULTS: Mean light reflex angles were reduced after surgery from 78.6° to 40.5° in the anterior neutral view (P = .0003), from 45.2° to 24.4° in the anterior extended view (P = .003), and from 7.03° to 4.32° in the lateral view (P = .006). Median survey ratings of neck photographs were improved after surgery, from 4 to 3 in gender perception toward more feminine perception (P < .0001) and from 4 to 2 in thyroid protrusion toward less protrusive perception (P < .0001). CONCLUSIONS: Morphometric analysis in anterior and lateral views as well as subjective gender perception and contour protrusion measures following feminization chondrolaryngoplasty by endoscopic transvestibular scarless approach demonstrate encouraging possibilities as outcome evaluation measures for chondrolaryngoplasty.

Negative Predictive Value of Circulating Tumor Tissue Modified Viral (TTMV)-HPV DNA for HPV-driven Oropharyngeal Cancer Surveillance.

PURPOSE: Human papillomavirus (HPV) is causally linked to oropharyngeal squamous cell carcinoma (OPSCC). Consensus guidelines recommend clinical exams and imaging in decreasing frequency as part of posttreatment surveillance for recurrence. Plasma tumor tissue modified viral (TTMV)-HPV DNA testing has emerged as a biomarker which can inform disease status during surveillance. EXPERIMENTAL DESIGN: This retrospective observational cohort study involved 543 patients who completed curative-intent therapy for HPV-associated OPSCC between February 2020 and January 2022 at eight U.S. cancer care institutions. We determined the negative predictive value (NPV) of TTMV-HPV DNA for recurrence when matched to physician-reported clinical outcome data (median follow-up time: 27.9 months; range: 4.5-154). RESULTS: The cohort included mostly men with a median age of 61 who had locoregionally advanced disease. HPV status was determined by p16 positivity in 87% of patients, with a positive HPV PCR/ISH among 55%; while pretreatment TTMV-HPV DNA status was unknown for most (79%) patients. Patients had a mean of 2.6 tests and almost half had three or more TTMV-HPV DNA results during surveillance. The per-test and per-patient sensitivity of the assay was 92.5% [95% confidence interval (CI): 87.5-97.5] and 87.3% (95% CI: 79.1-95.5), respectively. The NPV for the assay was 99.4% (95% CI: 98.9-99.8) and 98.4% (95% CI: 97.3-99.5), respectively. CONCLUSIONS: TTMV-HPV DNA surveillance testing yields few false negative results and few missed recurrences. These data could inform decisions on when to pursue reimaging following first disease restaging and could inform future surveillance practice. Additional study of how pretreatment TTMV-HPV DNA status impacts sensitivity for recurrence is needed.

Influence of Otolaryngological Subspecialties on Perception of Transoral Robotic Surgery: An International YO-IFOS Survey.

BACKGROUND: To investigate perception, adoption, and awareness on the part of otolaryngology and head and neck surgeons (OTO-HNS) of transoral robotic surgery (TORS). METHODS: Several items assessed: awareness/perception; access to TORS; training; indications and advantages/hurdles to TORS practice. A subanalysis was performed to assess differences according to the identified otolaryngological subspecialties. RESULTS: A total of 359 people completed the survey. Among subspecialties, while for otolaryngologists 30/359 (8.4%) and H&N surgeons 100/359 (27.9%) TORS plays an effective role in hospital stay, laryngologists frequently disagreed (54.3%). There was a lower incidence among rhinologists and otologists (1.9%). Pediatric surgeons (0.8%) reported a positive response regarding the adoption of robotic surgery, and head and neck specialists expressed an even greater response (14.2%). Low adherence was related to perceived cost-prohibitive TORS, by 50% of H&N surgeons. CONCLUSIONS: Perception, adoption, and knowledge about TORS play a key role in the application of the robotic system, significantly varying across subspecialties.

Surgery or botulinum toxin for adductor spasmodic dysphonia: a comparative study.

OBJECTIVES: Currently, botulinum toxin (Botox) injection is the standard of treatment for adductor spasmodic dysphonia (ADSD). We sought to compare the outcome of selective laryngeal adductor denervation-reinnervation (SLAD-R) surgery for ADSD to that of Botox injections. METHODS: Patient-oriented measures (VHI-10) and objective single-blinded gradings of digital voice recordings were utilized as outcome measures. The surgical cohort, recruited by retrospective patient selection, consisted of 77 patients with a mean follow-up time of 7.54 +/- 2.55 years (range, 2.2 to 14.2 years). The injection cohort, recruited prospectively, included 28 patients with a mean follow-up time of 46.37 +/- 5.51 days (range, 36 to 54 days). RESULTS: As measured by the VHI-10, the surgical patients had significantly improved voice handicap outcome scores (mean, 14.4 +/- 13.6) as compared to the patients who had Botox injection (mean, 26.5 +/- 12.1; p = 0.001). Aside from VHI-10 item 2, the surgical group demonstrated significantly improved voice-related function on each VHI-10 component (p = 0.01). Within the injection subgroup, 88% agreed that Botox successfully treats their ADSD, yet only 63% agreed that Botox improves their speech consistently. Within the surgical subgroup, 82% would recommend this surgery to others, and 78% agreed that their voice was actually better after surgery than after Botox. Objective voice ratings demonstrated similar levels of breathiness and overall voice quality in the treatment subgroups. CONCLUSIONS: When indicated, the SLAD-R surgery for ADSD demonstrates outcomes equal to or superior to those of the current standard of Botox injections.

Snail as a novel marker for regional metastasis in head and neck squamous cell carcinoma.

OBJECTIVE: Previous studies have shown Snail expression integral to the epithelial-mesenchymal transition during tumor progression. However, its behavior in clinical head and neck squamous cell carcinomas (HNSCCs) is yet undefined. We therefore sought to (1) investigate clinical and histopathologic characteristics of Snail-positive HNSCC and (2) understand the link between Snail and other commonly used HNSCC tumor markers. STUDY DESIGN: A retrospective case-control study was conducted. SETTING: This study was conducted in a large-scale academic center. STUDY SUBJECTS: Of 51 consecutive HNSCC, 42 surgical resections were included. METHODS: Two separate pathologists performed standard histopathologic reviews along with immunohistochemistries (Snail, E-cadherin, p16, epidermal growth factor receptor [EGFR]) and in situ hybridization (human papilloma virus [HPV]). Medical review for all cases was performed. RESULTS: Twenty-two (52%) of 42 cases stained 4+ Snail (>75% staining). The remaining 20 cases were considered negative. Snail was strongly inversely related to E-cadherin expression (ρ = -0.69, P < .001), but statistically independent from HPV, p16, or EGFR expression. Snail(+) tumors were equally represented from each anatomic subsite. Snail(+) tumors were strongly associated with poor differentiation (P < .001) and basaloid classification (P = .004). Snail(+) tumors were also strongly associated with lymphovascular invasion (P = .02), but not perineural invasion. Ultimately, 11 (50%) of 22 of Snail(+) tumors demonstrated positive nodal metastasis and 11 (79%) of 14 node-positive cases were Snail(+) (P = .02). CONCLUSION: This pilot study provides promising evidence of Snail' role as a molecular prognostic marker for HNSCC. Snail positivity is significantly predictive of poorly differentiated, lymphovascular invasive, as well as regionally metastatic tumors. Because Snail positivity appears independent of HPV, p16, and EGFR expression, Snail may prove to improve upon these markers' predictive limitations.

Transoral Feminizing Chondrolaryngoplasty: Development and Deployment of a Novel Approach in 77 Patients.

Importance: Transgender patients who desire a gender-congruent neck contour may forego transcutaneous procedures due to the risk of neck scar stigmata related to such procedures. Objective: To describe the development and experience with the first 77 cases of a novel gasless transvestibular technique for gender-affirming surgery of the laryngeal prominence. Design, Setting, Participants: Video and narrative description of a novel surgical technique, and case series describing the consecutive first 77 patients to undergo transoral chondrolaryngoplasty (TCLP) at a quaternary transgender referral center. Results: Between November 2019 and April 2022, 77 patients underwent the novel surgery of TCLP. Median follow-up was 8.74 months (range: 1-30 months). Four patients suffered surgical complications (two laryngotomy, two skin necrosis), and three patients requested revision surgery. Conclusions and Relevance: TCLP is reported in the largest published series to date offering hidden incision for gender-affirming care. With further prospective outcome investigations, TCLP may prove to be a reliable approach of performing chondrolaryngoplasty while avoiding visible neck incisions.
