Sudden deafness associated with bilateral Reissner's membrane ruptures
American Journal of Otolaryngology
|January 1, 1983
Summary
This histologic study reports sudden deafness in a patient with vertebro-basilar arteriosclerosis. The study found healed cochlear membrane ruptures, suggesting vascular insufficiency may predispose to inner ear membrane rupture.
Area of Science:
- Otolaryngology
- Neurology
- Pathology
Background:
- Sudden deafness is a complex condition often linked to inner ear pathologies.
- Vertebro-basilar arteriosclerosis is a significant vascular condition affecting blood supply to the brainstem and cerebellum.
Observation:
- A case study detailing a patient experiencing sudden deafness in both ears over a three-year period.
- The patient had a history of vertebro-basilar arteriosclerosis.
- Histologic examination of temporal bones revealed healed ruptures in cochlear membranes.
Findings:
- Two healed ruptures were identified in the right cochlea, one in the hook portion and another near the promontory, the latter causing saccular distortion.
- A healed rupture was also found in the left temporal bone, distal to labyrinthectomy obliteration.
- These ruptures occurred in the context of vertebro-basilar artery disease.
Implications:
- While sudden deafness and vascular disease were considered separate, the findings suggest a potential link.
- Chronic vascular insufficiency may increase susceptibility of inner ear membranes to rupture from pressure changes.
- This case highlights the importance of considering vascular health in patients with recurrent inner ear issues.
