Introduction: The ability to treat more advanced laryngeal cancers by transoral approaches has expanded significantly in the past several decades. Transoral management of laryngeal cancers that require removal of the laryngeal framework is controversial. Resecting cartilage through endoscopic means carries inherent technical challenges and the question of oncologic safety. Methods: We describe a retrospective review of patients undergoing resection of the thyroid cartilage during transoral laser microsurgery (TLM) for laryngeal cancer over a 10-year period. Only patients with 5-year follow-up were included. Results: Fourteen patients were identified that underwent attempted endoscopic resection of the thyroid cartilage. Preoperative staging ranged from T1 to T4 laryngeal cancers. Most patients underwent resection of the thyroid cartilage either for close proximity of the tumor to cartilage or microscopic involvement of the inner perichondrium, although 6 patients had gross invasion of the cartilage. Twelve patients underwent successful endoscopic clearance. Two patients were converted to total laryngectomy either at the time of surgery or shortly after due to extent of disease that was deemed not amenable to endoscopic resection. Overall 5-year survival was 71%. Disease-free survival was 62% at 5 years. The majority of patients avoided gastrostomy and tracheostomy tube dependence. One patient underwent total laryngectomy following initial TLM for chronic aspiration. Conclusion: We conclude that TLM for laryngeal cancer performed with removal of thyroid cartilage is feasible. Both oncologic and functional outcomes are reasonable in a select group of patients. This paper describes that cartilage can be resected endoscopically in the appropriate setting and not necessarily that cartilage invasion should routinely be treated with TLM.

Only seven cases of a sphenoid mucocele occurring after transsphenoidal hypophysectomy have been previously reported in the world literature. In this article, we report a new case, which occurred in a 67-year-old man. The sphenoid sinus mucocele developed 12 years following transsphenoidal hypophysectomy and adjunctive radiotherapy. The patient was successfully managed with incision and drainage. Although transsphenoidal hypophysectomy is a common operation, this particular complication appears to be rare or at least under-reported. Sphenoid sinus mucocele deserves consideration in the differential diagnosis of a sphenoidal parasellar mass in a patient who has undergone an earlier transsphenoidal hypophysectomy.

AbstractBackgroundThe American Joint Committee on Cancer (AJCC) eighth edition introduces a staging system specific for human papilloma virus positive oropharyngeal cancer with separate clinical (AJCC 8c) and pathological (AJCC 8p) criteria.MethodsIn this retrospective cohort study, preoperative imaging and pathology reports were used to stage patients based on the AJCC 8c and AJCC 8p criteria, respectively. The primary endpoint was agreement between AJCC 8c and AJCC 8p.ResultsA total of 213 patients met inclusion criteria. Kappa statistics showed poor agreement (κ = 0.3275) between AJCC 8c and AJCC 8p. In total, 30.3% of patient's preoperative AJCC 8c stage changed based on the postoperative pathologic staging (AJCC 8p) with 73.4% of those being upstaged.ConclusionThese data suggest that disagreement exists between AJCC 8c and AJCC 8p, in part due to the separate clinical and pathological staging criteria. This discrepancy should be considered as the new system is implemented.

ObjectivesPost‐acute care (PAC) centers, such as skilled nursing facilities, unskilled nursing facilities, lower acuity hospitals, and rehabilitation centers, serve to optimize recovery after acute care hospitalization. We aimed to identify factors associated with PAC utilization among patients undergoing head and neck cancer surgery with microvascular reconstruction because it may be helpful for patient decision making, discharge planning, and resource allocation.MethodsRetrospective linked analysis of the 2011 to 2015 National Surgical Quality Improvement Program. Eligible patients were identified and stratified by discharge disposition (home or PAC) after their postoperative acute‐care hospitalization. After an initial univariate screen of demographic and clinical variables, a multivariable logistic regression analysis was performed modelling discharge to PAC.ResultsOf the 1,652 identified patients, 261 (15.8%) were discharged to PAC. Those admitted to PAC were older, had a higher burden of comorbidity, and were more likely to be functionally dependent. They also had longer surgeries, longer hospitalizations, higher rates of reoperation, and higher rates of postoperative complications. After multivariate analysis, factors independently associated with PAC discharge included increasing age (odds ratio [OR] 2.12 per 10‐year increase; 95% confidence interval [CI], 1.81–2.48), active smoking status (odds ratio (OR) 1.61; 95% confidence interval (CI), 1.13–2.29), prolonged hospitalization (OR 1.04; 95% CI, 1.02–1.07), and postoperative pulmonary complications (OR 2.02; 95% CI, 1.36–2.99).ConclusionOf the patients undergoing surgery for head and neck cancers with microvascular reconstruction, 15.8% are discharged to PAC. Age, active smoking status, prolonged hospitalization, and postoperative pulmonary complications (vs. comorbidity, functional status, or primary tumor site) are independently associated with discharge to PAC.Level of EvidenceLevel 2c.

Introduction: The purpose of this study was to compare different decellularization protocols with the conventional detergent enzymatic method (DEM) using continuous agitation. Methods: The first experiment compared conventional DEM with sonication and lyophilization+freeze-thaw cycles. A second experiment was carried out to compare time-adjusted DEM (2-hour instead of 4-hour incubations with 4% deoxycholate) to decellularization in a bioreactor. Cellularity was determined by DNA-quantitation, H&E-staining and immunostaining for major histocompatibility complex-1 (MHC-1). Results: Compared to untreated trachea, DNA content significantly decreased after 2 cycles in all groups in the first experiment and dropped below the minimal criteria for efficient decellularization (<50 ng dsDNA/mg dry weight) after 4 cycles. However, nuclei were seen in the cartilage and MCH-1 staining was detected in some submucosal areas, indicating presence of chondrocytes and cellular residues that may render the scaffold immunogenic. In the second experiment DNA content significantly decreased after 1 cycle in both groups; however, even after 4 cycles, DNA content was above the minimal criteria for efficient decellularization. While collagen-levels remained stable, glycosaminoglycans diminished significantly after the initial cycles. Conclusions: Efficient decellularization can be achieved after only 4 cycles of DEM compared to the 17 cycles previously reported. The use of a bioreactor can preserve the integrity of the extracellular matrix.

Background Endoscopic endonasal resection (EER) of sinonasal mucosal melanoma (SMM) is a newer surgical alternative to traditional external and/or open resection (OR). Studies on long-term outcomes are necessary to validate EER for this aggressive sinonasal malignancy. Objective To compare outcomes of EER versus OR in SMM. Methods A case series of patients who underwent surgical resection of SMM at a tertiary-care institution (2000–2015) was studied retrospectively. Demographics, tumor site and stage, surgical approach, surgical margin status, local control, and survival were compared between those who underwent EER and OR. Results Twenty-two patients met inclusion criteria. Nine underwent EER and 13 underwent OR. The mean age in the EER and OR groups was similar, 78.7 and 72.3 years, respectively. Two-thirds of patients were women (EER, 66.7%; OR, 61.5%). The nasal cavity was the most common primary tumor site (EER, 77.8%; OR, 84.6%). The local tumor stage in both groups was similar, with the majority of cases being T4 (EER, 55.6%; OR, 61.5%; p = 0.99). Negative margins were achieved in all EERs and in 69.2% of ORs. Median follow-up was 25.0 months for the overall group (range, 1.7–172.9 months), 32.6 months (range, 3.4–58.7 months) for EER and 14.1 months (range, 1.7–172.9 months) for OR cohorts. The 5-year overall survival was statistically similar in both groups (EER, 53.3%; OR, 22.7%; p = 0.214) as was disease-free survival (EER, 55.6%; OR, 22.8%; p = 0.178). Local control, however, was significantly higher in the EER cohort (EER, 85.7%; OR, 37.6%; p = 0.026). Conclusion In carefully selected patients with sinonasal melanoma, endoscopic surgery with an experienced team may offer comparable survival and improved local control over open surgery. Prospective, multicentered studies with larger cohorts are needed to validate these results.

Purpose: To report the outcomes of patients with favorable risk oropharyngeal cancer that underwent adjuvant radiation therapy with omission of the primary site from the clinical target volume (CTV). Material/Methods: A retrospective study of 40 patients treated with transoral surgery (TOS) followed by neck only radiation using intensity modulated radiation therapy (IMRT) with exclusion of the primary site. For all patients, a CTV of the primary surgical bed was contoured to obtain the estimated incidental dose to the primary site. Results: Median follow-up was 51 months (range, 13-155 months). The median radiation therapy (RT) dose to the neck was 6000 cGy (range, 5400-6400 cGy). The mean incidental dose to the primary tonsillar site was 4320 cGy (SD ± 480 cGy) and to the primary base of tongue site was 4060 cGy (SD ± 420 cGy). There were no local failures and only 1 regional failure, resulting in 97.5% locoregional control rate at 4 years. Two patients developed distant metastases, without evidence of locoregional recurrence, for a 4-year overall survival rate of 97%. Conclusions: Our analysis suggests that mucosal sparing RT after TOS in favorable risk oropharyngeal cancer patients may provide comparable oncologic and improved functional outcomes compared to conventional treatment in selected patients.

ObjectivesTo compare reconstructive techniques, operative times, duration of hospitalization, and need for subsequent flap revisions between reconstructive approaches to lateral skull base defects.Study DesignCase series with chart review.SettingTertiary academic referral center.SubjectsPatients (n = 31) undergoing reconstruction of composite lateral skull base defects from 2002 to 2014.MethodsData were analyzed for demographics, tumor characteristics, reconstructive technique, operative time, duration of hospitalization, complications, and outcomes.ResultsThirty‐one patients were identified for inclusion. Lateral temporal bone defects resulted from resection of malignant lesions, including squamous cell carcinoma (n = 25), basal cell carcinoma (n = 2), and other carcinoma (n = 4). Defects were reconstructed with submental flaps (n = 16), pedicled latissimus dorsi flaps (n = 6), and free anterolateral thigh flaps (n = 9). All cases involved neurosurgery, neurotology, and head and neck surgery services. Although time of surgical resection was similar, time saving was noticed with submental reconstruction. Compared with free flaps, submental flap reconstruction was associated with significantly reduced total operative time (mean, 544 vs 683 min; P =. 00817) and duration of hospitalization (4.9 vs 9.8 days; P =. 02067). Submental flaps were significantly less likely to require revision debulking procedures (mean = 0.6) compared with latissimus dorsi flaps (mean, 1.3; P <. 00001) and free flaps (mean, 1.6; P <. 00001). There was 100% flap survival.ConclusionThe musculocutaneous submental flap provides an excellent option for reconstruction of lateral skull base defects given its proximity, reliability, ease of harvest, and exceptional color match. Submental flap reconstruction was associated with reduced operative time, hospitalization duration, and flap revisions.

Dissecting cellulitis of the scalp, or Hoffman’s disease, is a rare dermatologic condition characterized by recurrent pustules and sinus tract formation leading to scarring and alopecia. Medical management includes the use of corticosteroids, antibiotics, isotretinoin, and adalimumab. In cases where the disease is severe, refractory, and intractable, surgery is an option. We report two cases of Hoffman’s disease, where medical management failed to achieve remission. Surgical treatment was undertaken with complete resection of the affected scalp in staged procedures with subsequent split-thickness skin grafting for reconstruction. Surgery achieved both disease remission and excellent aesthetic outcomes in both patients.
