CPT® Code 21255

The procedure described by CPT® Code 21255 involves the reconstruction of the zygomatic arch and glenoid fossa using bone and cartilage grafts, which may be harvested from the patient's own body, known as autografts. This surgical intervention is typically indicated for patients who have suffered trauma or have congenital deformities affecting the zygomatic arch, which is the bone that forms the prominence of the cheek, and the glenoid fossa, the socket in the temporal bone that receives the head of the mandible. The procedure aims to restore the structural integrity and function of these facial components, which are crucial for both aesthetic appearance and proper jaw function. The surgical technique includes making an incision near the ear to access the affected area, followed by the careful resection of tissue to expose the zygomatic arch and glenoid fossa. The harvested graft, often taken from the rib, is then meticulously placed into the prepared recipient bed, and secured using various fixation methods such as wires, plates, or screws. Finally, the incisions are closed to promote healing and minimize scarring.
