| dc.description.abstract | The study aimed to investigate temporomandibular joint (TMJ) arterial variability. In this prospective study, the vasculature variability was studied using a 3D volume rendering CT angiography including random patients at two hospitals. A 16-quadrant (A1-D4) evaluation grid was developed using the Frankfurt plan as main reference. For each quadrant, the number of arterial ramus or branches was scored as clearly visible (2), partially visible (1), or not visible (0). A total of 50 patients were enrolled (mean age of 62.9 ± 16.0); 21 (42%) were men, and 29 (58%) were women. The authors observed bilaterally higher arterial density in the posterior aspect of the ascending ramus of the mandible (p < 0.0001), corresponding to quadrants B2 (5.92 ± 2.27 and 6.14 ± 2.56), B3 (9.76 ± 2.97 and 11.18 ± 2.86) and B4 (7.38 ± 2.78 and 8.10 ± 2.42). A strong correlation was found between the number of vessels and the variability of the region (r ¼ 0.87, p ¼ 0.00001). No differences were observed between men and women. Within the limitations of the study, arterial variability was observed in the TMJ territory. The posterior zone of the condyle and ramus is the most vascularized area, with great variability, representing an increased risk for surgical bleeding. Therefore, this knowledge seems to be particularly relevant for surgeons dedicated to TMJ and other facial surgery or facial/cerebral radiologic interventions. The authors encourage future studies to include larger samples and to identify thoroughly the arterial branches in this area. | pt_PT |
