Posttraumatic labyrinthitis ossificans with perilymphatic fistulization

Area of Science:

• Otolaryngology
• Neuroscience
• Radiology

Background:

• Labyrinthitis ossificans involves fibrosis or ossification of the inner ear's membranous labyrinth.
• Common causes include tympanogenic, meningogenic, and hematogenous spread, with trauma being less frequent.
• Understanding the varied etiologies is crucial for diagnosis and management.

Observation:

• A patient presented with right-sided hearing loss, otitis media symptoms, and positional vertigo.
• The symptoms were attributed to perilymphatic fistulization.
• Positional vertigo and hearing loss indicate inner ear dysfunction.

Findings:

• Imaging confirmed labyrinthitis ossificans.
• The ossification was secondary to a temporal bone fracture.
• The fracture extended through the otic capsule, implicating direct trauma to the inner ear structures.

Implications:

• This case underscores temporal bone fractures as a potential cause of labyrinthitis ossificans.
• Early diagnosis through imaging is vital for managing hearing loss and vertigo.
• Further research into trauma-induced labyrinthitis ossificans is warranted.
