Description

<p>Transoral surgery is a minimally invasive treatment procedure for superficial laryngo-pharyngeal cancer. We retrospectively evaluated the data of 42 patients with superficial laryngo-pharyngeal cancer who underwent transoral surgery at our department between January 2012 and December 2021. We performed 61 transoral surgeries, including transoral videolaryngoscopic surgery (TOVS) (47 cases) and endoscopic laryngopharyngeal surgery (ELPS) (14 cases) in 42 patients with hypopharyngeal cancer (46 cases), oropharyngeal cancer (8 cases), supraglottic cancer (5 cases), hypopharyngeal and esophageal cancer (1 case), and pharyngeal cancer after laryngectomy (1 case). In most of the cases (50 cases, 82%), the diagnosis was made by upper gastrointestinal endoscopy. The pathological T stage was Tis, T1, and T2 in 31 cases, 26 cases, and 4 cases respectively, and 11 patients developed metachronous multiple laryngo-pharyngeal cancers. Simultaneous double cancer was found in 29 patients; 21 patients (50%) had esophageal cancer and 8 patients (19%) had head and neck cancer. Locoregional recurrence occurred in 7 (16.7%) patients. Three patients developed aspiration pneumonia and 2 patients developed pharyngeal stenosis after surgery. Transoral surgery is a useful and developing procedure for superficial laryngo-pharyngeal cancer and should be applied in carefully selected cases.</p>
