Endoscopic versus microscopic type 1 tympanoplasty in chronic suppurative otitis media- tubotympanic type

Background Chronic suppurative otitis media attributes to 71.6% of hearing impairment in which most of them only have central perforations without any ossicular erosion or middle ear pathology. There are insufficient explanations to conclude which technique is better for type 1 tympanoplasty. Hence the study was conducted to compare and analyze the endoscopic technique with conventional microscopic technique for performing type 1 tympanoplasty.

Methods This prospective study was done at Basaweshwara teaching and general hospital attached to MR medical college, Kalaburagi from December 2015 to June 2017 after obtaining institutional ethical clearance. Patients were selected according to inclusion and exclusion criteria and randomly posted for surgery by either endoscopic or microscopic technique and results were analyzed.

Results There were 60 patients in the study between 11-65 years with mean age of 28.85±10.87 years in which were 28 females and 32 were males. All patients were divided into 2 groups in which 30 underwent endoscopic and 30 underwent microscopic type 1 tympanoplasty. In this 46.7% of the patients had left ear conductive hearing loss whereas 31.7% of patients had right ear conductive hearing loss and 21.7% of the patients had bilateral conductive hearing loss which included 22 small perforations, 33 medium size perforations and 5 large perforations of pars tensa.

Conclusions We conclude that endoscope can be a better alternative for microscope in type 1 tympanoplasty as it provides a wide panoramic view, less operating time and hospital stay with negligible scar post operatively.
