European laryngological society propose four types endoscopic supraglottic laryngectomy

Abstract

The limited excision addresses small superficial lesions affecting free edge of the epiglottis, the aryepiglottic fold or the superior edge of the arytenoid. The median supraglottic laryngectomy excluding the pre-epiglottic space addresses small superficial T1 lesions of the endolaryngeal epiglottis. The incision line extends to the pre-epiglottic space but does not aim at removing the pre-epiglottic space entirely. The pharyngo-epiglottic folds, aryepiglottic folds, and ventricular folds are preserved. The median supraglottic laryngectomy including the pre-epiglottic space addresses T1 and T2 lesions of the endolaryngeal epiglottis. The entire pre-epiglottic space is removed as far as possible. Depending on extent of the lesion, the resection can include one or two ventricular bands and the aryepiglottic folds. The lateral supraglottic laryngectomy addresses lesions affecting the three folds or T1 and T2 lesions of the aryepiglottic fold. The procedure removes free edge of the epiglottis ipsilateral to the lesion, the area of the three folds and the aryepiglottic fold. The resection can include the inner wall and anterior angle of the pyriform sinus, the entire ventricular fold and the arytenoid (provided it is mobile).
