Background: The treatment of T1b glottic carcinomas with invasion of the anterior commissure (AC) is still a challenge in larynx oncology. The diversity in treatment protocols is due to the difficulty in achieving safety margins of resection, especially in the AC.

Objective: The treatment success rate of frontolateral vertical partial laryngectomy (FVPL) for the treatment of stage T1b squamous cell carcinoma of the glottic larynx infiltrating the AC.

Material And Methods: Clinical data of patients, who were diagnosed with stage T1b squamous cell carcinoma of the glottic larynx and who underwent a FVPL from 01/2003 to 12/2016 in our ENT clinic were retrospectively evaluated. Clinical and oncological outcomes were analyzed.

Results: 39 patients were included in this study. The mean follow-up duration was 79.95 ± 20.59 months. Intraoperative R0 resection was achieved in all patients. In 33.3% patients, documented complications were tissue granulation and synechia formation in the glottic area. The 5-year recurrence-free survival was 82.1%, the 5-year overall survival rate 97.4%, and the 5-year laryngeal preservation rate 94.8%.

Conclusion: Our clinical data demonstrate that T1b glottic carcinomas with invasion of the AC can be effectively treated with FVPL. The outcome is similar to other methods such as transoral laser microsurgery, supracricoidal partial laryngectomy, and radiotherapy.

Early-stage laryngeal cancer (T1-T2) is commonly treated with organ-preserving techniques such as transoral laser microsurgery (TOLMS) or radiation therapy (RT), both providing comparable oncological outcomes but differing in functional results. Local recurrence occurs in approximately 10% of cases, making salvage surgery a crucial therapeutic option. This multi-institutional study investigates the efficacy of open partial horizontal laryngectomy (OPHL) as a salvage treatment, following recurrent laryngeal squamous-cell carcinoma (LSCC) after failed TOLMS.

 Supracricoid partial laryngectomy is a surgical treatment for advanced laryngeal cancer which is implemented to preserve organ function, but it may cause obstructive sleep apnea syndrome (OSAS) due to anatomical changes after surgery that may be neglected by clinicians. Although the gold standard for the diagnosis of OSAS is polysomnography, respiratory polygraphy is an alternative valid method with a high level of diagnostic sensitivity and specificity; since the equipment is portable, it can be used at home, with no need for hospitalization.  To describe the polygraphy result of patients submitted to supracricoid partial laryngectomy.

Tucker's Reconstructive Laryngectomy: Indications and Functional Outcomes.

Department of Ear, Nose, Throat and Head and Neck Surgery, Farhat Hached University Hospital, University of Sousse, Sousse, 4000, Tunisia.

Introduction: Frontal anterior laryngectomy with epiglottic reconstruction (Tucker's reconstructive surgery) is a technique of partial laryngectomy that has been used by several authors since its introduction in the 80s.The aim of this serie is to specify the indications of this operation and to present the functional and oncological outcomes of our study and those found in the literature.

Materials And Methods: We report a retrospective study of 65 cases who underwent Tucker's operation by many surgeons at our educational center over a period of 31 years (1988 - 2020).

Objectives: We aimed to compare the outcomes of patients with T1-T2N0M0 glottic squamous cell carcinoma who underwent either partial laryngectomy (PL) or radiotherapy (RT).

Methods: A retrospective analysis of 562 patients treated with RT (n = 151) or PL (n = 411) was conducted. The Kaplan-Meier method was used to estimate outcomes.

Study Design: A single institution, retrospective case-cohort study.

Methods: The present study retrospectively reviewed the clinical charts of a cohort of 100 elderly laryngeal squamous cell carcinoma (LSCC) patients who underwent OPHL at our institution.
