Four studies comparing cochlear implant (CI) hearing outcomes in individuals with temporal bone fractures to hearing outcomes in non-head injured individuals with CI reported comparable Consonant Nucleus Consonant, speech perception, Bamford-Kowal-Bench (BKB), and functional scores. Across studies, 14.5% of patients experienced complications, many of which were considered major complications that required inpatient treatment or follow-up surgery; facial nerve stimulation complications occurred most frequently. Overall, "hearing outcomes following CI in patients with temporal bone fractures are generally good with the majority of patients experiencing a benefit, both in terms of pure tone audiology and speech perception" (p. 172). Additional research with larger sample sizes and standardized outcome reporting is needed to increase the validity of pooled results.
