Summary
A rare traumatic perilymph fistula in an infant, caused by a metallic wire, was successfully treated. Surgical repair of the oval window and tympanic membrane resolved nystagmus, with the infant recovering well.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Trauma Surgery
Background:
- Traumatic perilymph fistula is uncommon in infants due to anatomical differences.
- Early diagnosis and intervention are crucial for managing such injuries.
Observation:
- An infant presented with a traumatic perilymph fistula in the right ear after a metallic wire injury.
- Symptoms included horizontal-rotatory nystagmus and evidence of ossicular dislocation on CT scans.
- Perilymph fluid leakage was observed at the oval window.
Findings:
- Surgical repair of the perilymph fistula using connective tissue was performed under general anesthesia.
- The incus-stapes joint was repaired, and the dislocated stapes footplate was repositioned.
- The tympanic membrane perforation was successfully closed with temporal fascia.
Implications:
- Surgical management can effectively treat traumatic perilymph fistulas in infants.
- Restoration of the oval window and tympanic membrane resolved nystagmus.
- Prompt surgical intervention leads to favorable outcomes and normal development in affected infants.
