Transmastoid repair of superior semicircular canal dehiscence

Abstract

Successful operative management of superior semicircular canal dehiscence can be achieved via the transmastoid approach under local anaesthesia.

Outpatient repair of superior semicircular canal dehiscence via the transmastoid approach

“…Of their three reported patients, all had complete resolution of their SSCD symptoms, and all had preserved or improved hearing. Following this publication, Kirtane et al6 provided a case report of a similar technique with similar results, and Crovetto et al7 similarly offered a brief technique description of transmastoid resurfacing of SSCD.…”

Evolution in surgical management of superior canal dehiscence syndrome

“…The first of these alternative methods to be described was a transmastoid approach with a plugging of the superior semicircular canal [3]. The first case report was described by Kirtane in 2009 and performed under local anesthesia, constituting the first reported alternative surgical treatment method to the standard middle fossa approach used up to that point.…”

Outcomes and complications in superior semicircular canal dehiscence surgery: A systematic review

“…This opening is also called the third window, in reference to the oval and round windows, the two physiological openings of the otic capsule . Superior semicircular canal dehiscence (SSCD) syndrome is a condition characterized by the presence of sound‐ and/or pressure‐induced vertigo or oscillopsia due to the dehiscence of bone overlying the superior semicircular canal . Vestibular activation in response to acoustic stimulation is termed the Tullio phenomenon, whereas vestibular activation elicited by pressure changes in the external auditory canal or Valsalva maneuver is referred to as Hennebert's sign .…”
