Pulling the skin off to expose the skull!! This is a coronal flap to the upper facial skeleton!! This is a frontal bone (forehead) exposure for facial reconstruction after a car accident. A coronal flap approach is indicated to expose the anterior cranial vault, the forehead, and the upper and middle regions of the facial skeleton, known as the craniomaxillofacial region. It is used in the repair of extensive upper facial/craniofacial fractures after extreme accidents. The advantage is that with strict adherence to surgical principles, is poses minimal complications during surgery as well as an aesthetic advantage of a hidden scar in the hairline.
My husband had this surgery due the trauma from a home invasion. I can actually find it fascinating now, at the time all I wanted was for him to live.
