Abstract

INTRODUCTION: Vocal cord lesions like vocal nodules, polyps and cysts though benign are significant because they disrupt the vocal fold vibratory function causing dysphonia. Removal of lesion, restoring the vibratory function and optimizing the voice are the goals of treatment of benign vocal fold lesions. Lesions not responsive to voice therapy / medical therapy have to be excised. Objective and subjective assessment of the laryngeal functions before and after surgery help to evaluate the effectiveness of the treatment. Quantification of such results also helps to compare voice outcome using different techniques. AIM OF THE STUDY: To compare the efficacy of Conventional microlaryngeal excision with Coablation for benign vocal cord lesion. METHODS AND MATERIALS: A sample of 40 patients with a clinical diagnosis of benign vocal cord lesions (polyp, nodule and cyst), were enrolled in our study. Each patient preoperatively underwent videolaryngoscopic examination and the disease severity was assessed with Voice handicap index and GRBAS score,after procuring the consent from them. Conservative treatment was tried and treatment failure patients were randomly divided into two groups viz. Conventional and Coblation method of microlaryngeal surgery. All the operated patients were reassessed at first week,first month and third month with Videolaryngoscopy, VHI and GRBAS score and the reults were analysed. RESULTS: In our study of 40 patients with benign vocal cord lesions, the overall post operative recovery was good in both the group. Surgical ease was better in the coblation group. But both the VHI score and GRBAS score was better in conventional group with significant p value(0.005). CONCLUSION: Coblation being a newer technique can be employed for surgical treatment for microlaryngeal surgery considering its advantages and less time consumption. Yet conventional microlaryngeal surgery with cold steel still gives better result comparatively.
