Postoperative Results of Superior Semicircular Canal Dehiscence: Analysis of 350 Surgical Interventions

1

Superior semicircular canal dehiscence (SSCD) results from bone thinning over the superior semicircular canal, leading to vestibular and auditory symptoms.
2

High-resolution CT and vestibular evoked myogenic potentials are essential for diagnosing SSCD, which can present with various auditory and vestibular symptoms.
3

Surgical repair of SSCD is often necessary for debilitating symptoms, with the middle cranial fossa approach providing better symptom resolution than the transmastoid approach.
4

This study analyzed 350 SSCD surgeries, making it the largest database to evaluate postoperative outcomes based on demographic factors.
5

The minimally invasive keyhole craniectomy method was used for repairs, employing various materials to either resurface or plug the dehiscence.
