Background To evaluate the importance of larynx compartments in prognosis T3-T4a laryngeal cancer treated with transoral laser microsurgery. Methods Two hundred and two consecutive pT3-T4a carcinomas. Pre-epiglottic space involvement, anterior posterior paraglottic (PGS) vocal cord, arytenoid mobility were determined. Local control (LC), overall survival (OS), disease-specific (DSS), laryngecto...

Laryngeal schwannomas are extremely uncommon. We present a case of bulky supraglottic schwannoma with involvement of the preepiglottic and superior paraglottic spaces. Clinical findings, computed tomography and magnetic resonance images are presented. These characteristics are typical, however not specific to schwannomas. For definitive diagnosis, histology and immunohistochemistry are necessar...

The definition of these sites is shown in Table 13.1. The larynx projects into the hypopharynx from the front so that grooves, known as the pyriform fossae, are formed on either side. These are shallow above and are separated from the valleculae by the pharyngoepiglottic folds. Lower down, the pyriform fossae become deeper. The upper shallow part of the pyriform fossa is bounded laterally by th...

A 47-year-old man was transferred from another clinic with a one year history of progressive dyspnea that had recently deteriorated. He was a heavy drinker (1 bottle of whisky/day) and smoker (1 pack/day). On the direct laryngoscopy, polypoid masses with smooth surfaces were found involving both the true and false vocal folds (Fig. 1A). We suspected the man was suffering from vocal cord carcino...
