Inner ear pathology associated with Reye's syndrome
International Journal of Pediatric Otorhinolaryngology
|December 1, 1983
Summary
Reye's syndrome causes severe inner ear damage, affecting hearing and balance. Pathological changes in the cochlear and vestibular systems were noted in a young patient.
Area of Science:
- Otolaryngology
- Neuropathology
- Pediatric Pathology
Background:
- Reye's syndrome is a rare but serious condition that causes swelling in the liver and brain.
- Inner ear involvement in Reye's syndrome has not been extensively documented.
Observation:
- A 2-month-old patient with Reye's syndrome exhibited severe pathological changes in inner ear tissues.
- Damage was more pronounced in inner hair cells than outer hair cells within the organ of Corti.
Findings:
- Degeneration was observed in non-sensory epithelial cells lining the cochlear duct.
- Reissner's membrane was frequently ruptured or collapsed.
- Both sensory and non-sensory cells in vestibular end organs showed marked degeneration.
Implications:
- These findings indicate acute inner ear pathology in Reye's syndrome.
- Such changes may lead to hearing and/or equilibrium impairment in survivors.
- Further research is warranted to understand the long-term effects on auditory and vestibular function.
