Abstract

Background: Parapharyngeal space tumors (PPST) are accounting for 0.5-1.5% of all head and neck tumors. Most of them are benign (80%); pleomorphic adenoma, neurogenic tumors are common. Treatment is mainly surgery. Depending on each case, the surgeon chooses the approach to the PPST. Endoscopy-assisted procedures have been introduced for the surgery of PPST because they can improve the visualization of critical neurovascular structures and margins of PPST. Objectives: To evaluate the effectiveness of endoscopy-assisted transoral approach for PPST. Methods: Prospective case series. 22 patients had endoscopy-assisted transoral approach for PPST in ENT department of ChoRay Hospital from 1/2018 to 12/2022. Results: Mean age was 50 (range: 19-75), male to female ratio was 1.05. Symptoms included tumor in mouth (18/22) and dysplagia (12/22). Most MRI or CT imaging noted clear-margin tumor in retroparapharyngeal space (22/22), with mean gross diameter 42mm (range: 32-60). Oral diet was started after surgery 5 days. No complications after surgery were recorded. Pathology reports were pleomorphic adenomas in 15/22 cases. Conclusions: PPSTs are uncommon tumors. Treatment is mainly surgery with multiple approaches. With the assistance of endoscopy, indications of transoral approach are widened with successful, safe and aesthetically pleasing results.
