Evaluating the Effect of Endoscopic Sinus Surgery on Laryngeal Mucosa Stroboscopic Features

The major presenting symptom of nasal polyps is nasal obstruction. The role of nasal obstruction in the genesis of laryngeal disorders is still unknown.
The aim of this study was to evaluate laryngeal videostroboscopic changes after functional endoscopic sinus surgery (FESS) in patients with nasal polyposis. A longitudinal study was carried out from March 2012 to June 2013. Thirty patients with bilateral nasal polyposis who did not respond to maximum medical treatment and were candidates for FESS were recruited. Laryngeal videostroboscopy was performed before and 3 months after FESS. Glottic gap, true vocal cord (TVC) borders and pliability, false vocal cord (FVC) movement, laryngeal erythema and mucosal edema were documented.
Laryngeal erythema and TVC edema were significantly decreased after FESS. Laryngeal erythema was documented in 18 patients after a 3-month follow-up. Four patients (13.3%) showed mild-to-moderate TVC edema and 26 patients (86.7%) had normal TVC mucosa.
The results of this study show that FESS has a significant impact on laryngeal videostroboscopic features including laryngeal erythema and TVC edema.
