Our Experience with Two Handed Endoscopic Tympanoplasty

Endoscopic tympanoplasty is a minimally invasive procedure and may be an alternative to conventional microscopic tympanoplasty with less operative time, producing similar graft uptake. Endoscopic tympanoplasty has a major disadvantage of single handedness which is overcome by a novel concept of "Two-handed technique" using Khan's Justtach (endoholder). The aim was to study the outcomes of two handed endoscopic tympanoplasty in terms of graft uptake and hearing outcome. Two handed endoscopic tympanoplasty was performed in 20 patients with chronic suppurative otitis media between April 2018-April 2019, in the Department of Otorhinolaryngology, M.G.M. Medical college and MYH hospital, Indore. Tragal cartilage graft via palisading supported with perichondrium was used. Postoperative follow up was done at 3rd month's period, graft status and hearing evaluation was done using Pure tone audiometry. Graft uptake was intact in 19 (95%) out of 20 patients and infection and failure in 1 (5%) case, average preoperative A-B gap was 15-25 dB loss (minimal) in 1 (5%) patient, 3 (15%) patients had 25-40 dB loss (mild) and 16 (80%) patients had 40-55 dB loss (moderate) hearing loss. The post-operative improvement was evaluated in which 6 (30%) patient had 15-25 dB loss (minimal), 12 (60%) patients had 25-40 dB loss (mild), and 2 (10%) patients had 40-55 dB (moderate) conductive hearing loss. We used Wilcoxon Signed Ranks Test for audiological evaluation with a 'p value' of 0.000 making the hearing improvement significant. "Two handed endoscopic tympanoplasty" is an emerging technique which can overcome almost all the major issues related with single handed technique with high degree graft uptake and good hearing outcomes. Endoscope holder is a valuable adjunct to conventional endoscopic surgery.
