Context: The recent change of using endoscope instead of microscope in performing transcanal type 1 tympanoplasty has encouraged us to compare the results of the surgery. Aims: The aim of this study is to evaluate hearing status in the pre- and post-operative state after endoscopic type 1 tympanoplasty and to correlate the improvement with influencing factors like the age of the patient, site and size of perforation, wet/dry ear, status middle ear mucosa, status of mastoid air cells, and function of Eustachian tube. Settings and Design: An interventional study was carried out in the Department of Otorhinolaryngology, RIMS. Materials and Methods: Thirty cases of diagnosed pars tensa central perforations, aged above 18 years, with a small to subtotal perforation associated with a demonstrable conductive deafness not more than 40 dB was included in the study. Statistical analysis used: Chi-square test. Results: The graft uptake rate in our study is 90% and hearing improvement in terms of airbone (AB) gap within 0-15 dB was achieved in 83.3%. Age, sex, size of perforation, site of perforation, wet/dry ear, and status of the mastoid air cell system were not found to have a significant relation with the successful outcome of endoscopic type 1 tympanoplasty. Presence of mucosal hypertrophy and the nonfunctioning of the Eustachian tube were a significant determinant for the failure of type 1 tympanoplasty. Conclusions: The outcome of endoscopic type 1 tympanoplasty is similar to the outcome of the microscope assisted type 1 tympanoplasty with better cosmesis. |
