The glottic-subglottic laryngectomy: Surgical technique, oncological, and functional outcomes.

OBJECTIVES: The aim of this article was to describe the surgical technique and report the oncological and functional outcomes of the partial glottic-subglottic laryngectomy (GSL). METHODS: A retrospective review of the clinical charts of patients who underwent GSL for laryngeal cancer from 1989 to 2020 at the Otolaryngology Unit of the Vittorio Veneto Hospital, a referral center for laryngeal cancer treatment. RESULTS: The present article considered 36 patients who were submitted to GSL for laryngeal cancer. The pathological exam found squamous cell carcinoma (SCC) in 16 cases, adenoid-cystic carcinoma (ACC) in 9 cases, laryngeal chondrosarcoma in 8 cases, 1 giant cell carcinoma, 1 carcinosarcoma, and 1 metastasis of colon adenocarcinoma. Considering the 16 SCC cases we observed a recurrence rate of 31%, the overall survival (OS) and disease-specific survival (DSS) were 75%. The 9 ACC cases had a recurrence rate of 23% and OS/DSS of 88%. In the 8 chondrosarcomas no relapses were reported and the OS/DSS were 100%. Among the patients without recurrence of the disease, a definitive decannulation was achieved in 21 cases (75%). CONCLUSIONS: The GSL represents a valid alternative to total laryngectomy in selected cases of laryngeal cancer involving the glottic and subglottic regions.

Lateral pharyngotomy approach in the treatment of oropharyngeal carcinoma.

Surgery for early-intermediate oropharyngeal squamous cell carcinoma (OPSCC) may involve using transoral endoscopic approaches or open surgical procedures. "Lateral pharyngotomy" (LP) is an open surgical approach that improves exposure of the oropharyngeal region, while avoiding mandibulotomy. The aim of the present study was to retrospectively analyze our experience with the surgical treatment of early-intermediate OPSCC using the LP approach, and to investigate the potentially prognostic clinical and/or pathological factors that might identify patients at higher risk of recurrence after primary surgery. Sixty-four patients with previously untreated early-intermediate (pT1-T2-T3) OPSCC consecutively underwent partial pharyngectomy using a LP approach, performed by the same surgical team at a tertiary head and neck oncology center (Otolaryngology Unit, Vittorio Veneto Hospital, Italy). The 2-year disease-specific survival rates were 86% for stage I-II and 77% for stage III-IV disease. All patients who experienced locoregional or distant metastases died of their disease, while no patients died of any complications of the treatment. Postoperative complications occurred in 25 patients (39%), the most common being pharyngocutaneous fistula. All but one of the patients experienced a complete recovery of oral food intake. In conclusion, the LP approach to oropharyngeal cancer could be a valid open surgical alternative to oropharyngectomy with mandibulotomy for: (a) patients with early-intermediate OPSCC in whom oropharyngeal exposure proves difficult, and/or who are not eligible for transoral endoscopic surgery; (b) HPV-negative OPSCCs; and

Transoral laser microsurgery for managing laryngeal stenosis after reconstructive partial laryngectomies.

OBJECTIVES/HYPOTHESIS: To retrospectively analyze our experience of transoral laser microsurgery (TLM) for treating postoperative laryngeal obstruction (POLO) after supracricoid and supratracheal laryngectomy (open partial horizontal laryngectomy [OPHL]) types 2 and 3, and to investigate potential relationships between patients' clinical features and their functional outcomes. STUDY DESIGN: A retrospective cohort study. METHODS: The prognostic influence of clinical and surgical parameters on functional outcomes was investigated in a univariate statistical setting in terms of decannulation rate (DR), time to tracheostomy closure (TTC), and number of laser procedures required (NLP). RESULTS: OPHL type 2 was associated with a better functional outcome than OPHL type 3 in terms of DR, TTC, and NLP (P = .03, P = .02, and P = .02, respectively). Annular and semicircumferential stenoses developed more frequently after OPHL type 3, and were particularly difficult to manage with TLM. Fixation of the residual arytenoid was a negative prognostic factor in terms of functional outcome in terms of DR, TTC, and NLP (P = .0002, P = .08, and P = .08, respectively). CONCLUSIONS: There is no standardized laser treatment for POLO; it must be tailored to individual patients. Identifying prognostic factors influencing functional outcome could help surgeons to earmark patients less likely to benefit from TLM for the treatment of POLO, and enable an adequate preoperative counseling, given the high probability of repeat postoperative TLM procedures.
