The application of pedicled middle turbinate mucosal flap in transnasal endoscopic repair of cerebrospinal fluid rhinorrhea

Abstract

Objective:To investigate the application and efficacy of pedicled middle turbinate mucosal flap in transnasal endoscopic repair of cerebrospinal fluid rhinorrhea. Methods:15 patients with cerebrospinal fluid rhinorrhea were retrospectively analyzed，including 13 patients with simple cerebrospinal fluid rhinorrhea （86.7%） and 2 patients with cerebrospinal fluid rhinorrhea with meningoencephalocele （13.3%）. According to the location of the fistula, the pedicled middle turbinate mucosal flap under nasal endoscopy was used to repair cerebrospinal fluid rhinorrhea, in which 5 cases （33.3%） had leakage at the top of the sieve and 8 cases （53.3%） had leakage at the sieve plate. Two cases had leakage at the lateral racess of sphenoid sinus. Results:All cases of cerebrospinal fluid rhinorrhea were repaired successful and the mucosa epithelialized well in the operative area. There was no recurrence of cerebrospinal fluid rhinorrhea or other complications during the follow-up period of 4-24 months （average 13 months）. Conclusion:The pedicled middle turbinate mucosal flap has a high success rate for repairing cerebrospinal fluid rhinorrhea, and the nasal cavity damage is small, which is worthy of clinical promotion.
