Sažetak
The aim of the study was to analyse zygomatic air cell defect (ZACD) incidence using MRI and validity of panoramic radiograph as a comparative method of ZACD diagnostics. The connection between ZACD incidence, age, left/right TMJ and co-morbidity with diagnosis of TMJ-disorder was analysed. Panoramic radiographs and MRIs of 140 TMJs of 70 consecutive patients with previously confirmed TMJ diagnosis were compared in the study. Grading system was used (4-point scale: “0” as absence to “3” as the most extended pneumatisation) to determine low signal on MRIs as a pneumatisation of the temporal bone. ZACD was diagnosed in 22 joints of 15 patients (incidence 20.4%) with 7 patients having bilateral appearance. In nine patients' joints ZACD was identified as extensive according to the grading scale. The validity of ZACD findings on panoramic radiographs compared with MRI findings was 0.45 sensitivity and 0.98 specificity. There was no relation (p>0.05) between co-morbidity of ZACD and TMJ-disorder, neither by age nor side of the body. More prevalent ZACD in our MRI analysis than in other researches based on panoramic radiographs is explainable by the expected superimposed osseous structures in the area of articular eminence.
