Summary
A rare stapes gusher complication in ear surgery can occur unexpectedly. Preoperative imaging like computed tomography scans may not always predict this risk, impacting hearing outcomes.
Area of Science:
- Otolaryngology
- Neurosurgery
- Radiology
Background:
- A stapes gusher, a rare but severe complication in ear surgery, can lead to significant hearing loss.
- Characteristic radiologic abnormalities on computed tomography (CT) scans often predict the risk of a stapes gusher.
Observation:
- This report details two cases of stapes gusher occurring despite normal preoperative CT scans.
- Neither patient exhibited pre-surgical radiologic indicators typically associated with this complication.
Findings:
- One patient developed sensorineural hearing loss, while the other experienced dizziness and tinnitus.
- Postoperative magnetic resonance imaging (MRI) scans also failed to reveal predictive features in these cases.
Implications:
- Surgeons must remain aware that preoperative CT scans may not identify all risks for perilymphatic gusher.
- This highlights the need for vigilance and potentially alternative diagnostic considerations in high-risk stapedotomy procedures.
