Abstract
Vocal cords are very delicated and intricate structure that help a human being to Breath, Speak as well as to sings. It is a micro structure and their functions are very accurate, even a small change in it by a lesion can produce enormous change in its function (Voice and Singing). Video Laryngo Stroboscopy is the process in which the normal and pathological vibrating pattern of vocal cord is made visible during phonation. Voice is analysed using Voice analyser and Voice Handicap Index. AIM OF THE STUDY: The present study is aimed at examining the objective and subjective parameters using Stroboscopy voice analysis and Voice Handicap Index(VHI) of patients with Benign Vocal Cord Lesions before and after Microlaryngeal surgery. METHOD: This study was conducted in the Department of Otorhinolaryngology of Government Stanley Medical College and Hospital during the period of December 2014 to September 2015. Based on the inclusion and exclusion criteria,38 patients with voice disorders were selected and sub categorized into Vocal Cord Nodule, Vocal cord Polyp, Vocal cord Cyst. Among 38 Patients 16 are presented as Vocal cord Nodule,16 Presented as Vocal cord Cyst and 6 Presented as Vocal Cord Polyp which includes both male and females. After getting valid consent from the patients, pre operative and Postoperative subjective and objective parameters using Stroboscopy voice analysis and Voice Handicap Index(VHI) were evaluated and analysed. RESULTS: Pre and Post operative assessment of patients with benign vocal cord mass lesions using stroboscopy, voice analyses and Voice Handicap index is a useful way to assess the degree of improvement following surgery. Both the patients and surgeon were provided with definitive evaluation with respect to the benefit following surgery and speech therapy. CONCLUSION: In conclusion pre and post operative assessment of patients with benign vocal cord mass lesions by stroboscopy, acoustic analysis and Voice Handicap Index is a useful way to assess the degree of improvement following surgery. Both subjective and objective parameters are assessed. Both patients and surgeons provided with a definitive evaluation with respect to the benefit following surgery and speech therapy.
