Temporal bone pneumatization and tegmen tympani defects in superior semicircular canal dehiscence: are they related to middle cranial fossa depth?

Key Points

• This research investigates the relationship between temporal bone pneumatization, tegmen tympani defects, and middle cranial fossa depth in relation to superior semicircular canal dehiscence.
• Analyzed anatomical features of temporal bone and middle cranial fossa in subjects with semicircular canal dehiscence.
• Measured the degree of temporal bone pneumatization and depth of middle cranial fossa.
• Correlated findings to assess their relationship with the presence of tegmen tympani defects.
• Increased temporal bone pneumatization is associated with higher rates of superior semicircular canal dehiscence.
• Greater middle cranial fossa depth correlates with the presence of tegmen tympani defects.
• The findings suggest a potential anatomical predisposition influencing these conditions.
