| Popis: | Introduction In surgical approaches to condylar fractures, there is a risk of damage to the transverse facial artery (TFA) which may in turn account for impaired blood supply to the temporomandibular joint (TMJ). In order to investigate the risk of damage to the TFA, and prevent lesions to this artery resulting from TMJ surgical procedures, we studied the distance between the TFA and the head of the condylar process. Methodology A dissection study was conducted on 10 fresh cadavers (20 condylar specimens dissected), involving fifty CT scans of the face with intravenous contrast. Vertical distance from the TFA to the top of the mandibular condyle head and distance from the TFA to the lateral aspect of the mandibular condyle were measured. Results The lateral aspect of the mandibular condyle is vascularized by branches emanating from the superficial temporal artery (STA) and the TFA. The TFA was located 1.84 ± 0.6 cm below the condylar process of the mandible and ran 1.09 ± 0.54 mm lateral to the head of the mandibular condyle. Discussion 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. |
