Middle fossa craniotomy and plugging of left-sided superior semicircular canal dehiscence
The patient is a 39 year old otherwise healthy woman with a long history of left-sided aural (ear) fullness, autophony (echo of the ear while talking or chewing), and worsening dizziness and vertigo that is worsened with straining, lifting, and loud noise exposure.
This video shows her surgery, a middle fossa craniotomy on the left side, extradural dissection to reveal the skull base and dehiscent superior canal, and plugging with bone wax. The surrounding skull base had multiple holes as well and was repaired using a split calverial bone graft from the bone flap raised during the craniotomy.
Post-surgery, she experienced a complete resolution of ear fullness and autophony, and improvement of her dizziness. She has returned to normal activities.
