Abstract :

 Chronic suppurative otitis media (CSOM) is a long standinginfection of a part or whole of the middle ear cleft. CSOM ischaracterized by ear discharge, a permanent perforation, andimpairment of heå. Statistics shows that in our country,there are about 5 crores of CSOM patients. Corrective surgery of CSOM provides dry ear with the improvementof heå in the majority of patients. The  introduction of endoscopy into middle ear has opened up new opportunities for minimally invasive temporal bone surgery. Endoscopy imaging provides dramatic new vistas to the otologist, and we are just in the early phase of developing the appropriate applications and supporting instrumentation.The endoscope ings the surgeon’s view into the depth of operative field and can provide a wide field of view with perspectives not possible with a surgical microscope. Operating microscopes provide magnified images in a straight line extending from the objective lens. Many deep recesses within temporal bone cannot be directly seen without the surgeon taking measures to expand the operative procedure.Endoscopes have an immediate advantage with an inherently wide field of view that extends from the tip of instruments lens. Additional angulation of view is accomplished by placing prisms into the tip. Endoscopes therefore offer the surgeon the capability of wide fields of view with minimal exposure, looking behind the obstructions or overhangs, and peering into recesses with much less requirement for surgical exposure than demanded by conventional techniques. Surgical morbidity and operating time can be substantially reduced.
