Introduction: Butterfly inlay tympanoplasty is a surgical procedure with tragus cartilage for repairing middle or small size eardrum defects under microscope or endoscope in general or local anesthesia. This study focused on the results and effectiveness of endoscopic butterfly inlay tympanoplasty under local anesthesia for large perforation in a single hospital.

Methods: This retrospective study was performed at a Hsinchu district hospital in Taiwan. The patients with large eardrum perforation underwent endoscopic butterfly inlay tympanoplasty from September 2019 to August 2022 was included. Data were collected as follows: sex, age, the threshold of pure tone audiometry, air-bone gap, size of perforation, and operation time.

Results: There were 11 patients with an average age of 60.5 (19-80 years), 5 male and 6 female. All of the patients had eardrum perforations over 40%, and were accepted endoscopy inlay tympanoplasty under local anesthesia. The graft take rate was 100% (of 11/11). 10 patients had accepted pre and post-operative hearing test. The mean pre- and post-operative hearing thresholds were 56.3 ± 14.9 dB and 43.4 ± 17.7 dB, respectively. The average air-bone gap closure was 10.6 ± 5.8 dB. The average operation time was 45.5 (33-57 minutes).

Conclusions: In this preliminary analyses, endoscopic butterfly inlay tympanoplasty can be performed under local anesthesia with satisfied result. It can be office-based procedure as an alternative to tranditional tympanoplasty. Long term follow up and more case numbers were needed for further result.
