Maxillary Artery Traversing Through the Temporal Muscle.

Few previous dissection reports demonstrated the possible course of the maxillary artery (MA) through the temporalis muscle (TM). A dissection study performed a long time ago established a 2% prevalence of this variant. As the variant was not studied on angiograms, we decided to do so. One hundred seventy archived computed tomography angiograms were used on 95 male and 75 female patients. The MA course through the TM was found in 11/170 cases (6.47%) but in 16/340 sides (5.58%). This is because, in 5/11 cases, the variant was bilateral. Therefore, preoperative computed tomography angiography could be helpful when surgical procedures using either the TM or the MA are designed. The course of the MA is variable, either deep or through the TM.
