Summary
Sudden sensorineural hearing loss (SSHL) can occur after spinal decompression surgery. Potential causes include anesthesia, pressure changes, and microemboli, necessitating further investigation and reporting of such cases.
Area of Science:
- Neurosurgery
- Otolaryngology
- Anesthesiology
Background:
- Spinal stenosis is a common condition requiring surgical intervention.
- Sudden sensorineural hearing loss (SSHL) is a rare but serious complication.
- Postoperative auditory complications after nonotologic surgery are not well-documented.
Observation:
- Two patients developed SSHL immediately following uncomplicated lumbar decompressive surgery.
- Hearing loss ranged from moderate to profound.
- Neither patient had a prior history of ear conditions.
Findings:
- Potential causative factors for SSHL post-spinal surgery include nitrous oxide, Valsalva maneuvers, and cerebrospinal fluid pressure fluctuations.
- Microemboli and viral infections are also considered possible contributors.
- SSHL is a rare complication, with only 26 prior cases documented after nonotologic, noncardiac bypass surgery.
Implications:
- Clinicians should be aware of SSHL as a potential, albeit rare, complication of spinal decompression.
- Further case reporting is encouraged to better understand the incidence and mechanisms of SSHL after spinal surgery.
- Prompt evaluation is crucial for patients experiencing hearing loss post-operatively.
