The Evaluation of Facial Artery Position in Related to Soft Tissue Pogonion and Soft Tissue Gonion: A Cadaver Study.

This anatomic study was designed to assess the position of the facial artery concerning the soft tissue landmarks, pogonion (Pog)and Gonion (Go). Sixty freshly frozen cadavers were used in this study. On the right side, the mean distance between the facial artery and Pog was 7.05±0.66 cm. The mean distance between the facial artery and Go was 3.34±0.36 cm. The results indicated that the facial artery was 32.32%±2.05 of a mandibular length to Go and 67.78%±2.05 Pog. On the left side, the mean distance between the facial artery and Pog was 7.10±0.65 cm. The mean distance between the facial artery and Go was 3.23±0.34 cm. The results indicated that the facial artery was 31.30±2% of the mandibular length at Go and 68.71±2% at Pog. The ratio of the facial artery distance to Pog and Go did not correlate with the mandibular length ( P >0.05). However, the distance between the facial artery, Pog, and Go correlated with mandibular length. ( P <0.001). The ratio of the cross-point of the facial artery with the mandibular border to the length of the mandible about Go and the Pog was generally found to be independent of mandibular length.
