ABSTRACT
BACKGROUND: The loss of laryngeal function affects breathing, swallowing, and voice, thus severely compromises quality of life. Laryngeal transplantation has long been suggested as a solution for selected highly affected patients with complete laryngeal function loss. OBJECTIVE: To obtain insights regarding the advantages, weaknesses, and limitations of this procedure and facilitate future advances, we collected uniform data from all known laryngeal transplants reported internationally. METHODOLOGY: A case series. Patients were enrolled retrospectively by each institutional hospital or clinic. Eleven patients with complete loss of laryngeal function undergoing total laryngeal transplantation between 1998 and 2018 were recruited. RESULTS: After a minimum of 24 months follow-up, three patients had died (27%), and there were two graft explants in survivors, one total and one partial, due to chronic rejection. In the remaining cases, voice was functional in 62.5% and 50% achieved decannulation. Swallowing was initially restricted, but only one patient was gastrostomy-dependent by 6 months and all had normal or near-normal swallowing by the end of year two after transplantation. Median follow-up was 73 months. Functional (voice, swallowing, airway) recovery peaked between 12 and 24 months. CONCLUSIONS: Laryngeal transplantation is a complex procedure with significant morbidity. Significant improvements in quality of life are possible for highly selected individuals with end-stage laryngeal disorders, including laryngeal neoplasia, but further technical and pharmacological developments are required if the technique is to be more widely applicable. An international registry should be created to provide better quality pooled data for analysis of outcomes of any future laryngeal transplants. LEVEL OF EVIDENCE: IV Laryngoscope, 2024.
ABSTRACT
BACKGROUND: Advancements in immunotherapy for recurrent head and neck cancer have necessitated a better understanding of salvage surgical outcomes. This study aimed to determine patterns of failure following salvage head and neck surgery. METHODS: A retrospective cohort study was conducted of 280 patients who underwent salvage surgery for recurrent mucosal squamous cell carcinoma from 1997 to 2018. Cumulative incidence was calculated using the nonparametric Aalen-Johansen estimator. Time to recurrence (TTR) and overall survival (OS) were estimated using the Kaplan-Meier method and multivariable Cox proportional hazard models were used to evaluate associated factors. RESULTS: The 2 and 5-year cumulative incidence rates of second recurrence were 48.3 % (95 % CI 42.4-54.3) and 54.9 % (95 % CI 48.9-60.8), respectively. At 5 years, second locoregional recurrence was twice as common as distant recurrence (41.5 % [95 % CI 35.6-47.4] vs. 21.7 % [95 % CI 16.8-26.6]). The median TTR was 21.1 months (95 % CI 4.4-34.8), which varied by site (38.2 larynx/hypopharynx, 13.9 oral cavity, 8.3 sinonasal, and 7.8 oropharynx, P=.0001). The median OS was 32.1 months (95 % CI 24.1-47.6) and was worse for patients who were Black (hazard ratio [HR] 2.15, 95 % CI 1.19-3.9), current smokers (HR 2.73, 95 % CI 1.53-4.88), former smokers (HR 2.00, 95 % CI 1.19-3.35), ≥ 60 years of age (HR 1.41, 95 % CI 1.01-1.97), or received multimodal primary therapy (HR 1.98, 95 % CI 1.26-3.13). CONCLUSION: Rates of recurrence and mortality after salvage surgery were poor but worse for patients who were Black, older, smoked, had initial multimodal therapy, or had sinonasal or oropharyngeal cancers.

BACKGROUND: Primary fit tracheoesophageal puncture (TEP) is widely preferred for individuals who have not undergone prior radiation. However, there is no consensus on the relative utility of primary-fit TEP in the setting of salvage laryngectomy. METHODS: A retrospective, single-center review was conducted of individuals undergoing laryngectomy with primary fit TEP between 2012 and 2018. Multivariable analysis was conducted to compare short-term and long-term complications, as well as speech and swallowing outcomes, of those who underwent primary versus salvage laryngectomy. RESULTS: In this study, 134 patients underwent total laryngectomy with primary fit TEP. Aside from a higher rate of peristomal dehiscence (13.1% vs. 1.4%) found in the salvage group, there was no difference in incidence of all other complications, including pharyngocutaneous fistula formation. The groups had comparable speech and swallow outcomes. CONCLUSION: Primary fit TEP is a safe and effective surgical choice for individuals undergoing salvage laryngectomy who desire a voice prosthesis.
ABSTRACT
BACKGROUND: Evaluate whether extranodal extension (ENE) extent impacts outcomes in patients with oral cavity squamous cell carcinoma (OCSCC). METHODS: From an institutional database, patients with OCSCC and pathologic ENE who received adjuvant treatment were included. Surgical slides were reviewed to confirm ENE extent. Multivariable Cox regression was used to relate patient/treatment characteristics with disease-free survival (DFS) and overall survival (OS). ENE was analyzed as both a dichotomous and continuous variable. RESULTS: A total of 113 patients were identified. Between major (>2 mm) versus minor ENE (≤2 mm), there was no significant difference in DFS (HR 1.18, 95%CI 0.72-1.92, p = 0.51) or OS (HR 1.17, 95%CI 0.70-1.96, p = 0.55). There was no significant association between ENE as a continuous variable and DFS (HR 0.97 per mm, 95%CI 0.87-1.4, p = 0.96) or OS (HR 0.96 per mm, 95%CI 0.83-1.11, p = 0.58). CONCLUSION: No significant relationship was seen between ENE extent and DFS or OS in individuals with OCSCC.

OBJECTIVE: Endoscopic management of subglottic stenosis (SGS) includes a wide range of techniques. This 17-year review compares treatment outcomes between carbon dioxide (CO2) laser and cold steel. STUDY DESIGN: Retrospective chart review. SETTING: Single tertiary care center. METHODS: A chart review was performed for all patients undergoing endoscopic treatment of SGS at Cleveland Clinic between July 12, 2000 and September 1, 2017. Data collected included demographics, stenosis etiology, stenosis severity, comorbidities, treatment modality, and airway procedure history. The primary endpoint was repeated treatment-free survival (RTFS) within 2 years using a Kaplan-Meier analysis and Cox proportional hazard model. RESULTS: A total of 139 patients (median [interquartile range] aged 48.7 [37.8, 57.0] years; 83.4% female) were included in the analysis, with etiologies including idiopathic (56.8%), granulomatosis with polyangiitis (25.2%), and intubation (16.5%). All patients underwent either cold steel (107 patients) or CO2 laser (32 patients) lysis of stenosis with concurrent dilation. RTFS within 2 years was 50.2% for CO2 laser and 31.9% for cold steel (hazard ratio [HR] and 95% confidence interval [CI]: 1.69, 0.96-2.97, P = .07). In patients with no prior airway procedures, there was no difference in RTFS between laser and cold knife (P = .41). However, in patients with prior airway procedures, RTFS was significantly greater in the laser group, even after adjusting for age, smoking history, and stenosis etiology (50.0% vs 16.8%, adjusted HR and CI: 2.82, 1.14-6.98, P = .025). CONCLUSION: Endoscopic lysis of SGS with CO2 laser should be considered in revision cases.
