Modified sutureless recess/tunnel technique for fixation of the internal receiver-stimulator in cochlear implantation

Abstract Background Fixation of receiver-stimulator (RS) in cochlear implantation is an important step surgery, while the technique used still debatable. Aim study The aim our to evaluate applicability modified recess/tunnel (R/T) fixation technique. Materials and methods De novo cases between august 2018 December 2020 were included. A bony recess was drilled deep full thickness RS. tunnel fashioned for fantail electrode lead with a groove slide it without trauma. No tie-down sutures used. length RS magnet tragus measured during follow-up visits. Results Seventy-eight patients received new R/T; 37 (47.4%) females. Children 50 (64.1%) average age 4.3 ± 2 years, adults 28 (35.9%) 36.4 10 years. Right implants 69 left ones only 9. total operative time 86 13 min, R/T preparation 11 4 min which represents 12.8% time. migration, hard. or soft failures detected. One case had postoperative haematoma originating from skin, other minor complications not related treated medically. Conclusion provides good RS, fantail, protection fixation. disadvantages wide exposure especially longer can be avoided this
