Abstract

Dysphonia is a common symptom in benign and pre malignant lesions of larynx affecting vocal cords. Surgical excision is the main stay of treatment. Only a limited number of studies have compared the efficacy of microdissection versus CO2 laser surgery in the larynx. In the present study we have compared conventional micro-laryngeal surgery and carbon dioxide laser assisted microsurgical technique in the management of these lesions. A randomized prospective study was conducted in 88 cases of benign and pre malignant lesions affecting vocal cords were divided randomly to undergo surgery either by conventional micro dissection or CO2 laser assisted techniques in a tertiary care hospital. The groups were assessed through vocal cord morphological observation by videostroboscopy and subjective voice assessment parameters GRBAS score and VHI10 index preoperatively and 2 weeks and 3 months postoperatively by a panel of blinded viewers and listeners. Surgical and recovery times were compared between the two groups. Intraoperative blood loss was compared by gauze visual analogue. Patients recovered remarkably well following both the techniques as denoted by the voice parameters. Peroperative bleeding was observed to be significantly reduced in the laser excision group; operating time was significantly increased in this group. Duration of hospital stay was similar in both groups. No differences in clinical outcomes are identified when comparing microdissection with laser excision of benign lesions.
