Summary
Wegener's granulomatosis can affect the temporal bone, causing hearing loss and facial nerve palsy. Early treatment with steroids and cyclophosphamide can improve these symptoms, highlighting the disease's otologic manifestations.
Area of Science:
- Otolaryngology
- Neurology
- Rheumatology
Background:
- Wegener's granulomatosis is a rare autoimmune disease that can affect various organs, including the temporal bone.
- Otic and neurologic manifestations, such as hearing loss and facial nerve palsy, can be presenting symptoms.
Observation:
- Two cases of Wegener's granulomatosis are presented with distinct initial symptoms: profound hearing loss and facial nerve palsy.
- Histopathology revealed granulation tissue invasion of the tympanic cavity and facial nerve, consistent with Wegener's granulomatosis.
Findings:
- Wegener's granulomatosis can lead to conductive, mixed, or sensorineural hearing loss due to middle and/or inner ear involvement.
- Facial nerve palsy in Wegener's granulomatosis is associated with granulomatous involvement and bony canal destruction.
Implications:
- Prompt diagnosis and treatment with steroids and cyclophosphamide are crucial for managing otologic and neurologic symptoms.
- Temporal bone histopathology is vital for confirming Wegener's granulomatosis in cases with unexplained hearing loss or facial nerve palsy.
