Videostroboscopic Evaluation of Patients with Benign Vocal Cord Lesions Following Micro Laryngeal Surgery in a Tertiary Care Centre

Background: Benign vocal cord lesions are one of the common causes of dysphonia. With the advent of microlaryngeal surgery, it is possible to remove lesions on the vocal cord precisely. Videostroboscopy is an advanced technique used to analyze the vibratory pattern of vocal fold mucosa. This study was conducted to compare the video stroboscopic findings in benign vocal cord lesions before and after surgery and to assess the outcome of surgical excision of benign vocal cord lesions on vocal fold vibration using video stroboscopy and voice analysis. Methodology: This prospective observational study was conducted among 46 patients with benign vocal cord lesions who underwent microlaryngeal surgical excision. in the Department of ENT, Government Medical College Thiruvananthapuram. Videostroboscopy, voice analysis, and voice handicap index were performed pre -and post -operatively. Postoperative results showed significant improvement in stroboscopic parameters, voice analysis, and voice handicap index, indicating effective surgical outcomes. Results: Postoperatively there was improvement in stroboscopic parameters of vocal cords. After surgery, objective and subjective voice improvement was observed in the voice analysis and voice handicap index respectively.
