Abstract

Purpose

In Le Fort 1 osteotomies there is a risk of injuring the maxillary artery, during the pterygomaxillary (PM) disjunction. To improve the knowledge of the relation between the maxillary artery and the PM suture, an anatomic study of the pterygopalatal fossa has been performed.

Methods

The study was based on CT scan head with vascular injection of the supraaortic trunks in 92 patients. The vertical length of the PM junction and the position of maxillary artery in relation to PM junction have been measured on a parasagittal plane passing through the lateral surface of the PM junction, and on a plane where the PM suture is the highest.

Results

The height of the PM junction on the plane passing through the lateral surface of the PM junction was 6.86 ± 2.67 mm, and the maxillary artery was located 18.22 ± 3.79 mm from the most inferior point of the PM junction. The maximum PM junction height was 13.96 ± 3.03 mm, and at this place the maxillary artery was located 18.85 ± 3.26 mm from the most inferior point of the PM junction. The distance between these two planes was 5.14 ± 2.02 mm.

Conclusions

According to our results, the height of the PM junction is less than 14 mm and during the PM disjunction there is a risk of injuring the maxillary artery 18 mm above the inferior extremity of the PM junction.
