Acute idiopathic sudden
sensorineural hearing loss (ISSNHL) following lumbar spinal surgery is an exceedingly rare phenomenon. This paper presents a case of ISSNHL presenting acutely after lumbar spine
decompression and fusion treated with transtympanic
steroids and hyperbaric
oxygen (HBO₂)
therapy. It also presents the ironic case of SSNHL secondary to presumed viral pathology sustained by the patient's operative surgeon who was treated with transtympanic
steroids and HBO₂ as well. Proposed etiologies of the patient's ISSNHL include:
hypotension, prone operative position, malfitted/malpositioned headrest, microemboli from a cell-saver, and
nitrous oxide anesthesia. The role of systemic
hypotension as an etiology of ISSNHL is discussed given the fact that there are no reported cases of ISSNHL in
orthopedic procedures performed with permissive
hypotension. The initiation of
steroids and HBO₂
therapy has been shown to be an effective treatment for ISSNHL when started within 14 days of symptom onset. HBO₂ and transtympanic
steroids were initiated 10 days earlier in the operative surgeon, which showed to be a better treatment modality compared to the postoperative patient. ISSNHL in the acute postoperative period of lumbar
spinal fusion surgery presents a unique treatment dilemma because systemic
steroids are routinely avoided over concerns of
pseudarthrosis. Of the seven documented cases of ISSNHL following lumbar spine surgery, none underwent HBO₂ as a treatment modality.
