Nasal polyposis is often encountered in rhinology practice. Those who fail conservative management, a definitive surgery is essential to achieve sufficient ventilation and drainage of the affected sinuses by using either microdebrider or conventional instruments for functional endoscopic sinus surgery (FESS). A prospective study was
conducted on 36 cases of nasal polypi in a tertiary care hospital. 18 cases were operated by conventional endoscopic instruments and 18 using the microdebrider.
The study aimed at comparing the intra operative (blood loss, duration of surgery)
and post operative results (crusting, scarring, discharge, symptoms, recurrence) between the two groups using Lund – Mackay scoring system and the data was statistically analysed.
There was no statistically significant difference in surgical outcome for patients when either conventional endoscopic instruments or microdebrider was used. However,
there was a significant symptomatic improvement in cases undergoing microdebrider FESS. Microdebrider assisted polypectomy is precise, relatively bloodless surgery though the precision depends on the surgeon’s anatomical knowledge and operative skills. Study substantiates that these instruments are helpful but not a prerequisite for successful outcomes in FESS. The study re-emphasises the utility of the microdeb-
rider to young learning FESS surgeons
