Outcomes of suture lateralization without tracheostomy for bilateral vocal fold paralysis

Abstract

Our objective is to describe the outcomes of endoscopic suture lateralization without tracheostomy for bilateral vocal cord paralysis (BVFP). This is a retrospective as well as a prospective study of 55 patients who presented to the Department of Otorhinolaryngology, First Central Hospital of Mongolia. The total of 55 patients was divided into 2 groups, group 1 consisted of 25 patients who underwent vocal cord suture lateralization from 2017 March to 2020 of October and group 2 consisted of 30 patients who underwent partial and total cordectomy by cold instruments and electrocoagulation before 2017. We did electroglottography, a peak flow meter for voice, and breath before and 1, 6 months after surgery. Maximum phonation time and harmonic noise ratio decreased after surgery in the case group (p<0.05). Other voice parameters no statistically changed. All voice parameters statistically changed in the control group. Peak inspiratory flow meter statistically increased in the case group compared than control group (p<0.05). Vocal cord suture lateralization without tracheostomy is minimally invasive, and in patients in whom function returns, it is reversible without damaging the structure of the vocal cord. Suture lateralization the advantages offered by chordectomy are evident in its rapidity, simplicity in concept, immediate assessment of airway size, better short duration hospitalization, and low risk of complications. The voice quality after surgery is not significantly altered SL is a superior, reliable and viable alternative to the chord, arytenoidectomy for BVFP.
