Repair of posterior semicircular canal dehiscence from a high jugular bulb.
Ontology highlight
ABSTRACT: Objectives
We describe the clinical evaluation and operative management of posterior semicircular canal dehiscence caused by a high jugular bulb.Methods
We performed a retrospective case report.Results
The patient had clinical and audiometric findings consistent with semicircular canal dehiscence and imaging findings that demonstrated erosion of the posterior semicircular canal by a high jugular bulb. Resurfacing of the eroded canal provided resolution of the vestibular symptoms without damage to the inner ear.Conclusions
Dehiscence of the posterior semicircular canal can cause clinical and audiometric findings similar to those of superior semicircular canal dehiscence syndrome. Resurfacing of the area of dehiscence can successfully relieve the vestibular symptoms. In the case of dehiscence of the posterior canal from a high jugular bulb, resurfacing may offer advantages over canal plugging for definitive management.
