Impact of Otoendoscopy in Cholesteatoma Surgery

To study the Impact of Otoendoscopy at the end of apparent microscopic clearance of disease during primary Cholesteatoma surgery in detecting the residual cholesteatoma. A prospective, interventional, non randomized and non comparative study was conducted at the ESIC Medical College and PGIMSR. All patients of chronic otitis media of squamosal type undergoing modified radical mastoidectomy were included in the study. Otoendoscopy was performed after apparent clearance of cholesteatoma under microscope. If any residual cholesteatoma detected during otoendocsopy was recorded. Total of 63 cases were included in the study. Residual cholesteatoma was seen in 14% of the cases. Commonest site of residual cholesteatoma was sinus tympani. Otoendoscopy helps in visualizing the deep recesses of the middle ear cleft for residual cholesteatoma after apparent clearance under the operating microscope. It also helps in clearing the cholesteatoma from these deep recesses there by it helps in reducing the recurrence rate of cholesteatoma.
