Branches of mandibular nerve formed a loop through which passed the second part of maxillary artery.

Arteriography demonstrates the vascular support of the tumor and evinces the embolization of the internal maxillary artery.

External carotid angiograms showed tumor stain mainly supplied by the temporal branches of the internal maxillary artery.

Results: Staged preoperative embolization of feeder arteries via internal maxillary artery, and thyrocervical trunk with onyx was performed.

We present an unusual case in which maxillary artery was found deep (medial) to lateral pterygoid muscle.

The relationships of the pterygospinosus muscle with the mandibular nerve and its branches and the maxillary artery and its branches were analyzed.
