Rare sudden hearing loss after lumbar spine decompression surgery: A case report and review of the literature

Sensorineural hearing loss (SNHL) is a known but rare complication of non-otological surgeries. SNHL after spinal decompression also remains a rare occurrence with a handful of reports in the literature. The exact mechanism is not clearly understood. Cerebrospinal fluid leak, barotrauma, microemboli, hypoperfusion, vasospasm, traumatic event, and anesthetic agents are some of the proposed etiologies. Early diagnosis and prompt intervention have shown benefits though management lacks consensus. We report a case of profound SNHL post-lumbar decompression and fixation surgery, who showed significant recovery at 4-week follow-up, and we review the literature for hearing loss after spine surgeries.
