“…In some cases in which the dehiscence is located adjacent to the superior petrosal sinus or the more posterior aspect of the canal near the common crus, the transmastoid approach is preferred. Alternatively, an angled endoscope may extend visualization for plugging via middle cranial fossa approach (94). Furthermore, in some cases the transmastoid approach is not feasible due to a contracted mastoid with a low-hanging tegmen.…”

Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal) that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

“…Moreover, the method employed in the present study may not be ideal for the study of the membranous labyrinth for which histological sections after decalcification will be the better choice. The knowledge of the normal anatomy of the ear is often called for in surgical procedures in this region such as removal of acoustic nerve tumor, repair of canal dehiscence, etc [10,11].…”

“…This was followed by reinforcement and repair of any associated tegmen defects by placement of a split calvarial bone graft and temporalis fascia grafting. Recently, a MFC approach using an angled endoscope was developed at our institution . The procedure uses a smaller craniotomy and minimizes temporal lobe dissection and retraction.…”

“…2,3 In some patients, SCD-related symptoms are severe and surgical repair is indicated. Surgical repair is performed using either middle fossa craniotomy (MFC) 4,5 or transmastoid approaches. 6,7 Common repair techniques include resurfacing the dehiscent area with bone graft and fat or fascia, or plugging the SSC with various materials, including bone wax.…”
