Superior Canal Dehiscence

All patients exhibiting positive clinical findings for SCD should be referred to an otolaryngologist. A multidisciplinary approach incorporating audiology and otolaryngology is optimal in the management of patients with SCD. The following treatment options may be considered.

Counseling

For less severe cases, counseling on avoidance of precipitating stimuli is sufficient to prevent the symptoms from becoming debilitating (Minor, 2000).

Surgical Intervention

Reserved for patients with severely debilitating symptoms, intervention consists of surgical repair of the superior canal via resurfacing or plugging (middle cranial fossa or transmastoid approach) (Brantberg, et al., 2001).

Amplification

In cases of persistent hearing loss, with or without surgical intervention, hearing aids may be helpful, based on the degree of loss and perceived handicap. However, consideration must be given to the Tullio effect.
