Experience of diagnosis and treatment of fibrovascular polyp of the hypopharynx

Abstract

Objective:To explore and analyze the imaging examinations, clinical presentation, operative methods complication and the surgical outcomes of fibrovascular polyp of the hypopharynx （hFVP）. Methods:The clinical data of 10 patients with hFVP were analyzed retrospectively from January 2015 to June 2020 at the First Affiliated Hospital of Zhengzhou University.Results: All the 10 cases were sporadic. The locations of pedicle: 5 cases were found in pyriform sinus （4 on the left side, 1 on the right side） ,3 cases were found in lateral pharyngeal wall （on the right side），and 2 cases were found in postcricoid space. Among 10 cases, 8 cases were treated with endoscopic coblation cauterization,1 case had excision of endoscopic laryngeal forcep, and 1 case for endoscopic CO2 laser treatment as well as coblation cauterization. Follow up for 5.9-71.4 （30.9） months showed that 7 cases had no recurrence, 2 cases had no connection, 1 cases had recurrence once. One patient recurred once underwent the last operation with transcervical approach as well as tracheotomy,and no recurrence was found in the follow up of 13.2 months. Conclusion:Fibrovascular polyp of the hypopharynx is rare benign submucosal neoplasm clinically, and endoscopic coblation cauterization is a good choice. Recurrent fibrovascular polyp of the hypopharynx can be treated by endoscopic coblation cauterization again, so that patients with multiple recurrences whose polyps are giant or euangiotic can consider the transcervical approach, if necessary, the tracheotomy will also be given.
