Abstract
Purpose
To observe the effectiveness of preoperative drug-induced sleep endoscopy in improving surgical results of patients undergoing single-level barbed pharyngoplasty surgery for OSA, using a prospective randomized model.
Methods
A single-center randomized controlled trial with two prospective arms was carried out to compare functional results in patients treated with barbed reposition pharyngoplasty (BRP) surgery without a preoperative drug-induced sleep endoscopy (DISE) evaluation vs patients treated with BRP surgery performed after DISE evaluation of sites/patterns of collapse.
Results
We compared 50 patients who underwent BRP without a preoperative DISE evaluation (Group A) and 42 patients (Group B) treated with BRP surgery but preoperatively selected by means of a preoperative DISE. In this second group of patients, after DISE evaluation, 70% of patients were selected for single-level BRP surgery because they showed an isolated velopharyngeal collapse at the DISE evaluation, without obstruction at other upper airway levels evaluated. Both groups of patients showed a statistically significant difference between preoperative and postoperative values of AHI, ODI, and LOS (p<0.05 in all cases). Comparing Group A and Group B patients, the therapeutic success rate was found to be 60% in patients treated without preoperative DISE evaluation and 83% in patients treated with preoperative DISE (p = 0.02).
Conclusion
DISE appears to improve the surgical results of single-level velopharyngeal surgery due to the possibility of excluding patients with obstruction of the base of the tongue, the hypopharynx, and the epiglottis/larynx.
