Abstract

Introduction: Cochlear implantation is a boon to children with hearing loss. Rarely, it can be associated with complications. Soft tissue reaction can be a particularly distressing complication.

Materials and methods: The study was conducted on all patients presenting with soft tissue reaction post-cochlear implant in a tertiary care referral institute from March 2011 to June 2018. We graded the severity of soft tissue reaction as per the severity and then managed these patients accordingly.

Results: Thirty-five patients were included in this study. Grade 1 had 12 patients, grade 2 had 9, grade 3 had 4 and grade 4 had 9 patients. Grade 1, 2 and 3 reactions were managed conservatively, while grade 4 required surgery. The incidence of explantations increased with the grade severity.

Conclusion: Soft tissue reaction post-cochlear implant is a rare, but distressing complication. Grading and analyzing them can help us manage them in a better way.
