Post-surgical and oncologic outcomes of frontal anterior laryngectomy with epiglottic reconstruction: a review of 68 cases

Laryngeal function-preserving of frontolateral vertical partial laryngectomy (FLVPL) for selected T4a glottic cancer with thyroid cartilage invasion adherence to the anterior commissure: an innovative attempt

“…Anatomically, the anterior commissure of the larynx is generally defined restrictively and functionally as the anterior insertion region of the vocals folds to the thyroid cartilage [ 11 ]. Due to the lack of vocal ligament and the inner perichondrium, cartilage’s resistance against tumor invasion is lower and is prone to high incidence of recurrence and so the cartilage adjacent to the tumors involving the anterior commissure must be resected [ 1 ]. Recently, the classification of larynx tumors based on compartments has been emphasized as an important point to the indications of partial surgery [ 10 ].…”

“…The rate of patients being restricted to soft or liquid food because of swallowing difficulties ranged from 9% to 23% after 1 year, depending on the therapy arm, and 14–16% after 2 years [ 4 ]. The median nasogastric tube removal time and decannulation time was 10 and 12 days about the frontal anterior laryngectomy [ 1 ]. These figures are much worse than those reported for FLVPL in our present study.…”

“…During our observation, a series of T4a patients have confined tumor in a subregion, and the outer cortex of the thyroid cartilage is involved with the tumor through anterior commissure. FLVPL is a surgical treatment option in early glottis LC involving the anterior commissure, and which is grounded on the anatomic and oncologic principles [ 1 , 7 ]. As a result of tumor causes, vertical cartilage resection requiring the removal of more than half of the vocal folds with anterior commissure is typically large.…”
