Objective:
This study aimed to assess the superior semicircular canal (SSCC) morphology and to determine whether superior semicircular canal dehiscence (SSCD) correlates with temporomandibular joint (TMJ) symptoms.
Study Design:
Clinical data and cone beam computed tomography (CBCT) scans of 175 patients were retrospectively examined by 2 observers. Distribution and thickness measurements of the different types of bone cover of the SSCC were performed.
Results:
Five radiologic SSCC patterns were identified from CBCT data: 147 cases (42%) were defined as normal (0.6-1.7 mm thickness); 62 cases (17.71%) had a papyraceous pattern (<0.5 mm); 77 cases (22%) showed a thick pattern (>1.8 mm); and 42 cases (12%) had a pneumatized pattern. Observer 1 and 2 diagnosed SSCD in 22 of 350 (6.28%) temporal bones individually and had no discordances between the 2 reviews. All patients with SSCD were identified as having TMJ signs and symptoms (P < .05).
Conclusions:
Maxillofacial radiologists should be informed about these structures, which can be helpful for the interpretation of CBCT scans.
