Endoscopic Cartilage Butterfly Tympanoplasty: A Two-Handed Technique with Endoscope Holder.

The aim of the study was to evaluate and report the short-term results of two-handed endoscopic cartilage butterfly tympanoplasty using endoscope holders. The efficacy of the operative technique was evaluated and assessed by comparing the air-bone-gap on pure tone audiometry preoperatively and on follow-up at 6 months and 1-year post operatively. Patients with uncomplicated otitis media and healthy middle ear status with no ossicular involvement underwent endoscopic transcanal cartilage butterfly tympanoplasty. Small and medium sized tympanic membrane perforations were included in the study. Pre- and postoperative air-bone gaps and presence for any residual perforation was noted. A total 69 patients consisting of 45 males and 24 females with a mean age of 24.45 years were included in the study group. Small perforations involving only one quadrant were 39 in number while the medium sized perforations involving two quadrants were 26 in number and the ones involving three quadrants were 4 in number. At the end of the follow-up period of 6 months and 1 year, successful closure occurred in 67 of 69 patients with a success rate of 97.1%. The mean preoperative Air-Bone gap was 34 ± 3.45 dB which showed a steady decline on follow-up at 6 months 13 ± 4.53 and 15.34 ± 3.39 dB at 1 year following surgery. Recurrent perforation was noted in two patients involving three quadrants of the tympanic membrane. Endoscopic two-handed butterfly cartilage tympanoplasty can be safely performed in small and medium sized perforations with no middle ear disease/ossicular involvement. The hearing outcomes and successful closure rate are similar to those of other surgical methods. Our study uses the endoscope which provides superior image quality and the use of an endoscope holder makes the technique a two handed one, thereby making the manoeuvring of the microear instruments easier. Moreover, it can be performed under local anaesthesia with low complication rates and quick recovery. Level of Evidence Level 4. © Association of Otolaryngologists of India 2020.
