Cochlear implant – experience and analysis of consecutive cases done in the Hearing and Speech Institute over a period of three months

Abstract

Purpose The aim was to analyze demographic and perioperative data of patients who underwent cochlear implantation (CI) at the Hearing and Speech Institute in the period between November 2019 and January 2020. Materials and methods Files of all patients undergoing CI in the period between November 2019 and January 2020 were collected used a specially designed checklist to record demographic, preoperative, operative, and early postoperative data. Data were recorded and analyzed using proper statistical analysis. Results Of 80 files reviewed, the data of 73 files were included. Average age was 4.3 ± 3.3 years, and 41 (56.2%) of them were males. Positive consanguinity was seen in 37 (50.7%) cases, positive family history was seen in 29 (39.73%), 13 (17.8%) cases had wide vestibular aqueduct, four (5.5%) cases had auditory neuropathy, and two (2.74%) cases had intracochlear anomalies. The average operative time was 85 ± 24 min. A total of 66 (90.4%) right ears were operated on. Difference in the operative time between wide vestibular aqueduct cases and normal cases was insignificant, whereas difference between right vs left ear operative time was significant. Early complications were reported in seven (9.6%) cases, and majority were partial facial palsy (5.5%). Conclusion Condensed CI work is possible in suitable environment of team discipline and adequate equipment, with comparable performance and outcome. In addition, it provides favorable conditions for training new surgeons.
