Using the Subglottic Pressure to Predict the Dysphagia After Partial Laryngectomy

An open partial horizontal laryngectomy(OPHL) was performed for patients with T2 supraglottic and glottic carcinoma, according to the American Joint Committee on Cancer(AJCC) criteria. Type I OPHL: Entails the resection of the supraglottis, including the pre-epiglottic space and the upper half of the thyroid cartilage. Type II OPHL: Entails the resection of the entire thyroid cartilage, with the inferior limit represented by the upper edge of the cricoid ring. Type III OPHL: Entails the resection of the entire supraglottic, glottic, and part of the subglottic sites, sparing both or at least one functioning crico-arytenoid unit.

"For patients with T1 glottic laryngeal carcinoma, according to the criteria of the American Joint Committee on Cancer(AJCC), transoral endoscopic CO2 laser(2-40Watts) cordectomy was performed. The classification comprises eight types of cordectomies:~* A subepithelial cordectomy (type I) is a resection of the epithelium of the vocal fold.~* A subligamental cordectomy (type II) is a resection of the epithelium, Reinke's space, and vocal ligament.~* Transmuscular cordectomy (type III), which proceeds through the vocalis muscle.~* Total cordectomy (type IV).~* Extended cordectomy encompasses the contralateral vocal fold and the anterior commissure (type Va).~* Extended cordectomy, which includes the arytenoid (type Vb).~* Extended cordectomy, which encompasses the subglottis (type Vc).~* Extended cordectomy, which consists of the ventricle (type Vd)."
