title: Recent advances in superior semicircular canal dehiscence syndrome.
abstract: OBJECTIVE
  This study aimed to review the current advances in superior semicircular canal dehiscence syndrome and to ascertain its aetiology, whether dehiscence size correlates with symptoms, signs and investigation results, the best investigations, and its surgical management.
  
  
  METHODS
  A literature search using the key words 'superior semicircular canal dehiscence' was performed using the Allied and Complementary Medicine Database and the Embase, Health Management Information Consortium, Medline, PsycINFO, British Nursing Index, Cinahl and Health Business Elite databases for the period January 2009 to May 2014. Systematic reviews, meta-analyses, randomised controlled trials, prospective and retrospective case series, case reports, and observational studies were included.
  
  
  RESULTS
  Of the 205 papers identified, 35 were considered relevant.
  
  
  CONCLUSIONS
  The aetiology of superior semicircular canal dehiscence syndrome is unclear. Dehiscence size significantly affects the air-bone gap and ocular vestibular evoked myogenic potential thresholds. Computed tomography evaluation has a high false positive rate. The middle cranial fossa approach is the surgical standard for treating this syndrome; however, the transmastoid approach is gaining popularity.
