OBJECTIVE: To examine the benefit of cochlear implantation (CI) in pediatric patients with a history of temporal bone fracture resulting in single-sided deafness (SSD).
STUDY DESIGN: Retrospective chart review.
SETTING: Two tertiary academic centers.
PATIENTS: Pediatric patients less than 18 years of age with SSD secondary to temporal bone fracture who underwent CI from 2012 to 2022.
INTERVENTIONS: CI.
MAIN OUTCOME MEASURES: Postoperative audiometric testing.
RESULTS: Seven subjects were identified (median age: 10 years (y); Q1 to Q3: 5 to 16 y). Median time from temporal bone trauma to CI was 7 months (mo) (Q1 to Q3: 3 to 7 mo) and 85% had otic capsule involvement. Subjects were followed for a median length of 12 months (Q1 to Q3: 6 to 24 mo) after CI. All patients achieved full electrode insertion, though 2 required scala vestibuli insertion due to ossification of the scala tympani (one of whom had a history of meningitis after temporal bone fracture). Postoperative audiometric testing revealed variable speech perception outcomes with 4 of 7 obtaining open or closed set speech perception and 3 of 7 obtaining only sound awareness. No postoperative complications occurred.
CONCLUSIONS: CI is a feasible intervention for SSD following pediatric temporal bone fractures, but outcomes are variable. Early evaluation and timely CI, ideally within 6 months of temporal bone fracture, may optimize outcomes. Cochlear ossification, either as a result of otic capsule fracture or subsequent meningitis, may lead to suboptimal outcomes.
