Abstract
Abstract Microdebrider as a new technology in the management of laryngeal lesions is a powered rotatory dissection device with suction assistance; it was used before in orthopedic surgery and sinus surgery. The aim of this work was to assess the microdebrider as a tool for excision of benign laryngeal lesions and compare its results (intraoperative and postoperative) with those of microlaryngeal surgery by cold instruments. Forty patients with benign vocal fold lesions were included (25 women and 15 men), with age ranging from 24 to 51 years. Group I was subjected to excision of lesions by the conventional instruments. Group II was subjected to excision of lesions by the microdebrider. Each patient was subjected to the protocol of voice assessment preoperatively and 3 weeks postoperatively. The patients were assessed subjectively by Voice Problem Self-Assessment Scale and objectively by laryngoscopy, stroboscopy, and acoustic analysis. No significant difference in the acoustic parameters between the two groups was observed, but there was significant difference between the preoperative and the postoperative acoustic parameters for each group. Postoperative parameters satisfactorily improved with resolution of the lesions in both groups. The microdebrider was determined to be a safe, accurate, and reliable method in removal of benign vocal fold lesions but does not offer major advantages compared with the standard instruments.

Microdebrider as a new technology in the management of laryngeal lesions is a powered rotatory dissection device with suction assistance; it was used before in orthopedic surgery and sinus surgery
Microdebrider use in endoscopic sinus surgery was first reported in 1996, and it was subsequently adapted for laryngeal applications in 1999
The inclusion criteria were patients presenting with voice complaints and diagnosed as benign laryngeal lesions namely polyps, nodules, granuloma, papilloma, or cyst, patients not responding to voice therapy, and patients who are fit for general anesthesia
Summary
Microdebrider as a new technology in the management of laryngeal lesions is a powered rotatory dissection device with suction assistance; it was used before in orthopedic surgery and sinus surgery. Microdebrider as a new technology in management of laryngeal lesions is a powered rotatory dissection device with suction assistance, which is designed to minimize trauma to the surrounding tissues [8,9]. Its application in laryngeal surgery is relatively new, but it has been in use for decades in orthopedic and temporomandibular joint surgery [9] This electrically powered instrument combines suction and irrigation functions with an oscillating blade within a protected sheath that provides continuous suction [10].
