Purpose: This study sought to assess the relationships between a morphological characteristic of the superior semicircular canal (SSC) and both the roof thickness of the glenoid fossa (GF) and bone changes of the temporomandibular joint (TMJ) on three-dimensional images.

Methods: Cone-beam computed tomography (CBCT) images of 200 individuals (105 females and 95 males; 400 temporal bone regions) were examined by two different observers. The correlations between the bone thickness overlying the SSC and the thickness of the roof of the GF with TMJ's bone pathologies were analyzed.

Results: The superior semicircular canal dehiscence (SSCD) was significantly associated with dehiscence of the roof of the GF. The relationship between the dehiscence of the SSC and the roof thickness of the GF was found to be strongly correlated (p < 0.05). There were no statistically significant differences between the bone changes of TMJ and the presence or absence of the SSCD.

Conclusions: A correlation between the bone thickness overlying the SSC and the roof thickness of the GF was found. However, there was no relationship between the bone thickness overlying the SSC and bone changes of TMJ.

Background: Superior canal dehiscence syndrome (Minor's syndrome) is a condition characterized by a bony defect in the superior semicircular canal (SSCC), with treatment primarily being surgical, notably through plugging of SSCC.

Aims/objectives: To examine the clinical outcome and postoperative VHIT findings after transmastoid plugging of the SSCC.

Materials And Methods: Patients having a superior semicircular canal dehiscence (SSCCD) syndrome with debilitating symptoms who underwent a plugging of the SSCC a transmastoid approach were included.

A severe case of bilateral superior semicircular dehiscence was presented in Instituto de Neurorrehabilitación y Balance, Chile. The patient reports hearing and vestibular problems in certain situations; a complete analysis is carried out from the clinical history to neurological laboratory studies and imaging to diagnose bilateral semicircular canal dehiscence finally. Health condition management is under the ICF model, which will allow for determining and classifying the problems and possible interventions for this interesting clinical case.

Introduction: The most common histopathological finding in Ménière's disease (MD) is endolymphatic hydrops (EH), which involves the dilation of the membranous labyrinth. The direct relationship between EH and MD is debated, although EH plays a crucial role in auditory and vestibular functional tests. MRI sequences such as 3D-FLAIR and 3D-real-IR are used to study EH, with the latter being more effective.
