Summary
Sudden sensorineural hearing loss is a rare complication following craniotomy in patients with otosclerosis. This hearing loss occurred immediately post-operation with no recovery in two reported cases.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Otosclerosis is a condition affecting the middle ear bones.
- Patients with otosclerosis may have vulnerable auditory systems.
- Craniotomy is a surgical procedure involving the skull.
Observation:
- Two patients with otosclerosis underwent craniotomy for unrelated conditions.
- Sudden sensorineural hearing loss was observed immediately after surgery in both patients.
- No hearing improvement was noted post-operatively.
Findings:
- Sudden sensorineural hearing loss is a rare complication of non-otologic, non-cardiopulmonary bypass surgery.
- This complication has not been previously reported in otosclerosis patients undergoing craniotomy.
- Vulnerable ears, such as those with otosclerosis or pre-existing hearing loss, may be susceptible.
Implications:
- Highlights a potential risk for patients with otosclerosis undergoing cranial surgery.
- Suggests careful consideration of auditory risk in otosclerosis patients undergoing non-ear related surgery.
- Emphasizes the need for awareness among surgeons and audiologists regarding this rare complication.
