The Transverse Facial Artery and the Mandibular Condylar Process: An Anatomic and Radiologic Study.

In order to spare the TFA in fractures involving the condylar neck, surgical approaches to the condyle should preserve the uppermost 2 cm of the lateral surface of the condyle during dissection. Due to the necessity for periosteal elevation of the lateral surface of the condyle in condylar head fractures, it is possible to spare the TFA, running lateral to the condylar neck, and the medial condylar surface in order to leave the branches that derive from the maxillary artery (MA) intact.
