Lateral Semicircular Canal Dehiscence
Otology & Neurotology, 2007genesis of these symptoms has been attributed to the presence of a third window, which provides a different path for the dissipation of acoustic energy (4). A subset of patients, however, are asymptomatic, and these patients’ conditions are diagnosed on imaging or postmortem analyses of temporal bones.

Congenital Dehiscence in the Posterior Semicircular Canal
Otology & Neurotology, 2013Posterior semicircular canal dehiscence (PSCD) may be of congenital origin.PSCD is characterized by the lack of bone coverage, which results in its lumen being exposed to the meninges of the posterior cranial fossa or to the gulf of the jugular vein. It has an incidence of 0.2%.

Operative Techniques in Otolaryngology-Head and Neck Surgery, 2014
In the evaluation of patients with suspected superior (or posterior or lateral) semicircular canal dehiscence syndrome, imaging plays a crucial corroborative diagnostic role. The variable audiologic and vestibular signs and symptoms may be attributed to a third-window phenomenon, directly visible on computed tomography as a defect in the superior or ...

Incidence of semicircular canal dehiscence in Singapore
The British Journal of Radiology, 2009Semicircular canal dehiscence is a congenital syndrome that mainly affects the superior and, less commonly, the posterior semicircular canals. The diagnosis of superior semicircular canal dehiscence syndrome depends on the demonstration of a very small defect in the bony wall of the superior semicircular canal.

Superior semicircular canal dehiscence syndrome
Journal of Neurosurgery, 2017Superior semicircular canal dehiscence (SSCD) syndrome is an increasingly recognized cause of vestibular and/or auditory symptoms in both adults and children. These symptoms are believed to result from the presence of a pathological mobile “third window” into the labyrinth due to deficiency in the osseous shell, leading to inadvertent hydroacoustic ...
