A PROSPECTIVE STUDY TO EVALUATE THE OUTCOME OF FLEXIBLE ENDOSCOPIC INJECTION THYROPLASTY IN PATIENTS OF VOCAL FOLD PARALYSIS

Abstract

INTRODUCTION Injection Laryngoplasty in the office setting have shown promising results with significant improvement in both subjective and objective voice outcome measures in patients of Vocal fold paralysis OBJECTIVE The aim of this study was to evaluate the safety, efficacy and outcome of Flexible Endoscopic Injection Type-1 Thyroplasty in patients of Unilateral Adductor Vocal fold paralysis METHOD A Prospective hospital based Interventional study was carried out in the department of ENT of a Tertiary Care Medical College and associated Hospital during a period of 22 months from January 2020 to October 2021. A total of 60 patients were selected according to Inclusion criteria and Exclusion criteria.Each of these patients underwent Injection Laryngoplasty with Gel foam under Local Anesthesia. Auditory perceptual assessment was done using modified GRBAS score, Voice Handicap Index and Maximum phonation time. RESULTS Statistical analysis revealed a significant difference between pre and post-injection voice quality as assessed by “GRBAS” scale and Voice Handicap Index (VHI). Maximum phonation time (MPT) was sufficiently increased following injection andimprovement was consistent throughout the follow-up periods. CONCLUSION Injection Laryngoplasty with gel foam paste is a temporary remedy for compensatory therapy for v o c a l c o r d p a r a l y s i s w i t h o u t a n y m a j o r disadvantages.
