Objective
This study investigates the importance of bone density, surface area, and diameter of anatomical structures of the superior semicircular canal (SSC), lateral semicircular canal (LSC), posterior semicircular canal (PSC), utricle, and saccule in patients diagnosed with superior semicircular canal dehiscence (SSCD).
Materials and methods
The bone density, surface area, and diameter of SSC, LSC, PSC, utricle, and saccule were measured and compared between the SSCD group and control group. Fifteen ears in the SSCD group and 60 ears in the control group were evaluated. Additionally, within the SSCD group, the dehiscent and healthy sides were evaluated independently.
Results
SSC’s bone density was significantly lower in the SSCD group compared to the control group (
p
 = 0.008). No significant differences were found in surface area and diameter between the groups (
p
 > 0.05). While most of the anatomical structures showed no significant difference in bone density between dehiscent and healthy ears (
p
 > 0.05), SSC bone density was significantly lower in affected ears (
p
 = 0.000) in SSCD group.
Conclusion
Based on the data obtained in this study, bone density and anatomical structure may be useful in patients diagnosed with SSCD.
