Endoscopic interlay tympanoplasty: our experience

Sajitha Bhaskaran K., Naveen Kumar


Background: Chronic otitis media is treated conventionally by tympanoplasty using a temporalis fascia graft using a microscope, through a post aural approach. The present study comprises of 50 cases of chronic otitis media, which were treated by endoscopic interlay technique of tympanoplasty, combining two novel approaches in otological surgery.

Methods: Total of 50 patients were studied, with in a period of one year at our institution. All of them underwent type I endoscopic tympanoplasty by interlay method. All of whom were followed up for 6 months. Patients were evaluated in terms of graft uptake, improvement in hearing and rate of complications.  

Results: In the present study, we have recorded a graft uptake rate of 98%. The mean post operative air bone gap at the end of 6 months was 0.9 dB (p=0.001) which was statistically highly significant.

Conclusions: Endoscopic interlay tympanoplasty is a novel and preferred technique, which could be implemented in all cases of dry chronic otitis media.
