Abstract
In present world of contemporary techniques of microscopic ear surgery and single handed endoscopic ear surgery, we propose the technique of two handed endoscopic tympanoplasty using endoscope holders. The aim of the study is to evaluate the functional and anatomical results of our technique of endoscopic type 3 cartilage tympanoplasty using endoscope holder. It is a Retrospective Non Randomized Clinical Study. A total of 67 endoscope holder assisted exclusively two handed endoscopic type 3 cartilage tympanoplasties performed from December 2014 to March 2017 with our technique were included in the study. Patients with pars tensa retractions and perforations with absent incus were included in the study. Those with cholesteatoma were excluded from the study. Full thickness tragal cartilage disc of 3 × 3 mm dimensions with a circular slot of 1 mm to fit onto the head of the stapes was used for reconstruction. Tympanic membrane reconstr uction was done along with attic reconstruction, using sliced tragal cartilage of 0.5 mm thickness. Patients were assessed at 6, 12 and 24 months for graft status. In early follow up period ranging from 24 to 52 months, the graft take up was seen in 64 ears with three perforations giving a success rate of 95.52%. The pre-operative air-bone gap was 42.6 ± 3.26 dB and the post-operative air-bone gap at 6 months, 1 and 2 years was 18.36 ± 3.46 dB, 19.42 ± 4.32 dB and 19.53 ± 4.33 dB respectively. The study reports good air-bone closure to 20 dB postoperatively following type 3 endoscopic tympanoplasty using endoscope holder. Slotted cartilage graft is definitely an excellent option for ossiculoplasty in cases of absent incus providing a stable assembly.
Level of evidence: Level 4.
