Oral SurgeryThe Gillies approach is a surgical technique used in facial reconstruction, particularly for the repair of facial defects. The superficial temporal artery is of significant anatomical importance during this procedure, as it supplies blood to the scalp and face. Surgeons must be cautious to avoid damaging this artery during the approach.

Oral PathologySystemic sclerosis (scleroderma) causes contracture of facial skin giving a masklike appearance due to excessive collagen deposition and skin tightening. This leads to loss of facial expressions and a characteristic "pinched" facial appearance with microstomia and radial furrows around the mouth. Craniofacial dysostosis, achondroplasia, and solar elastosis do not cause this specific masklike facial contracture.
