Introduction by Dr. Mark Levenson
Patients who present with a history of dizziness or vertigo with loud noise or on compression of the ear canal may have a hole in the bony canal of the inner ear. These patients also frequently experience echophony (hearing your own voice reverberating) and a mild hearing loss in that ear. These symptoms may be related to the abnormality described in the abstract below.

The article presents a minimally invasive surgical treatment for this condition performed as a same-day surgery which has had a high degree of success. Previous surgical treatments for this condition require opening of the skull and a combined ear and brain surgery approach for repair.

Dr. Levenson reports that new patients treated since the completion of the study have also enjoyed a high degree of success with round window reinforcement for superior semicircular canal dehiscence.

To evaluate the outcome of round window (RW) tissue reinforcement in the management of superior semicircular canal dehiscence (SSCD).


Twenty-two patients with confirmed diagnosis of SSCD by clinical presentation, imaging, and/or testing were included in the study. Six surgeons at four institutions conducted a multicenter chart review of patients treated for symptomatic superior canal dehiscence using RW tissue reinforcement or complete RW occlusion. A transcanal approach was used to reinforce the RW with various types of tissue. Patients completed a novel postoperative survey, grading preoperative and postoperative symptom severity.


Analysis revealed statistically significant improvement in all symptoms with the exception of hearing loss in 19 patients who underwent RW reinforcement. In contrast, 2 of 3 participants who underwent the alternate treatment of RW niche occlusion experienced worsened symptoms requiring revision surgery.


RW tissue reinforcement may reduce the symptoms associated with SSCD. The reinforcement technique may benefit SSCD patients by reducing the “third window” effect created by a dehiscent semicircular canal. Given its low risks compared to middle cranial fossa or transmastoid canal occlusion, RW reinforcement may prove to be a suitable initial procedure for intractable SSCD. In contrast, complete RW occlusion is not advised.
