Air-collection behind the ear: a rare complication in cochlear implant surgery
Summary
A rare cochlear implant complication, air collection behind the ear, occurred in a 61-year-old male. This case highlights the Eustachian tube test for preventing such rare surgical complications.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Imaging
Background:
- A 61-year-old male with profound sensorineural hearing loss underwent cochlear implantation.
- The patient developed a post-operative swelling behind the ear.
Observation:
- Ultrasonography suggested liquid content, but aspiration revealed 30 cm³ of air.
- This indicated a rare complication of air collection behind the cochlear implant receiver-stimulator.
Findings:
- Air collection behind the ear is a rare cochlear implant surgery complication.
- Ultrasonography is useful for localization and differentiating solid/liquid content but not for identifying air.
- An abnormally patent Eustachian tube may predispose to this complication.
Implications:
- Early identification and management of air collection are crucial.
- The Eustachian tube test may help identify patients at risk.
- This case underscores the importance of considering unusual complications in cochlear implant recipients.
