A midface flap, specifically a zygomaticofacial flap, is a surgical procedure utilized to address structural defects in the midface region. This type of flap is particularly important for reconstructive purposes following the resection of tumors, traumatic injuries to the face, congenital anomalies, or various inflammatory and degenerative conditions affecting the facial structure. The midface is a critical area that houses prominent facial features and plays a vital role in essential functions such as respiration, speech, chewing, swallowing, vision, and the sense of smell. The anatomical structure of the midface includes bones that support the orbital contents, the roof of the oral cavity, and the airway, as well as the olfactory units and sinuses. During the procedure, a template is created based on the dimensions of the skin deficit, which is then traced onto the donor site. The zygomatic bone serves as the superior border of this template, while the anterior auricular line, nasal sidewall, and nasolabial fold define the lateral, medial, and inferior borders, respectively. It is crucial to ensure that the flap is of adequate length to reach the defect without causing tension, while also allowing for contouring and accommodating any swelling that may occur postoperatively. The flap is then rotated and positioned over the defect to verify that its size and contours are appropriate for effective closure. This meticulous approach ensures that the resulting repair is not only functional but also aesthetically pleasing.
