Transoral robotic surgery for oncocytic ductal cyst of hypopharynx: a lesion with a high probability of recurrence

Abstract

Hypopharyngeal cysts are very uncommon pathology. They are presented in adult people over 60 years. Although oncocytic cysts are benign tumors, an incomplete resection causes recurrence. The symptoms are not specific, but the more frequent are dyspnea and foreign body sensation upon swallowing. Diagnosis usually is under general anesthesia during intubation. A flexible fiberoptic laryngoscopy could be insufficient; the trumpet maneuver during this examination can reveled occult cysts. To perform a total resection, the surgeon must have a complete exposition of the operative field. We present a new case of a patient with a symptomatic hypopharyngeal cyst successfully treated with transoral robotic extirpation; our view was tridimensional magnified and the robotic instruments provided great range of movement that permitted complete and safe removal hypopharyngeal lesion.

Alternative Applications of Trans-Oral Robotic Surgery (TORS): A Systematic Review

“…Despite anatomical difficulties, the hypopharynx can be approached by robotic surgery. The piriform sinus is the most described site of benign tumours and, in this way, parathyroid adenomas, fibromas, oncocytic ductal cysts and lipomas have been reported to be removed using the TORS technique in this area [19][20][21][22]. In one case, a robotic lysis of epiglottis synechiae was performed in a patient with an unusual presentation of pemphigus vulgaris [23].…”

Transoral Robotic Surgery for Head and Neck Cancer: Practical Considerations

“…TORS was first developed between 2004 and 2005 by Weinstein and O'Malley and approved by the Federal Drug Administration (FDA) in 2009 [6]. In Colombia, the first two TORS were performed for a benign pathology in 2013 and reported in 2018 by Cadena et al [7,8]. In this country, 26 patients have been treated with TORS; 11 of them had benign pathology, 14 oropharyngeal, and one supraglottic cancer.…”
