A STUDY OF CONVENTIONAL METHOD AND MICROFLAP BASED TECHNIQUE FOR EXCISION OF NON MALIGNANT VOCAL FOLD NODULAR LESIONS

Abstract

Introduction: Management of benign vocal fold nodular lesion provides a particularly good window into the revolution of voice surgery. The changes in approach to surgical management have resulted largely because of advancement in knowledge of anatomy and physiology of the vocal fold layered structures & technological developments that have improved our ability to examine and quantify voice function and the availability of better surgical instruments. Aims: Comparison of Microap technique with conventional method for benign vocal fold nodular lesion and Comparison of Intropertive and post-operative parameters like operative time, primary bleeding, operative procedures, residual tissue, collateral damage, postoperative complication, recovery time and so on between two methods. Materials and Methods: This study was Prospective Randomised single blind trial study. This study was conducted at Patna Medical College & Hospital, Department of ENT from Feb 2020-August 2022. Result: We found in Conventional Group, the mean Total Score of Pre-op Video Stroboscopy (Individual) (mean± s.d.) of patients was 9.2632± 1.9268. In Micro Flap Group, the mean Total Score of Pre-op Video Stroboscopy (Individual) (mean± s.d.) of patients was 8.7857± 1.6898. Difference of mean Total Score of Pre-op Video Stroboscopy (Individual) with both Group was not statistically signicant (p=0.2413). In Conventional Group, the mean Total Score of Post-op Video Stroboscopy (mean± s.d.) of patients was 2.2895 ± 3.3684. Conclusion:We found that Mean Total Score of Post-op Video Stroboscopy was higher in Conventional compared to Micro Flap group which was statistically signicant. It was showed that Mean Video Stroboscopy Outcome Difference (Pre-Post) was less in Conventional compared to Micro Flap group which was statistically signicant
