ABSTRACT
<p><b>OBJECTIVE</b>To analyze the audiologic results of cochlear implantation in bilateral severe to profound sensorineural hearing loss following head trauma.</p><p><b>METHODS</b>A retrospective study of our cochlear implantation cases in bilateral severe to profound sensorineural hearing loss following head trauma (with or without temporal bone fractures). Four patients in second hospital of Shandong university were analyzed in this study.</p><p><b>RESULTS</b>All the patients received unilateral cochlear implantation and gained open-set speech perception ranging from 92% to 100%. The aided hearing threshold ranged from 30 dBHL to 35 dBHL. None of them experienced a decrease in the hearing performance in the follow-up (1-2 years).</p><p><b>CONCLUSION</b>With sufficient preoperative assessment, cochlear implantation is an effective management for hearing rehabilitation in bilateral severe to profound sensorineural hearing loss following head trauma.</p>
