CPT® Code 21175

Reconstruction, bifrontal, superior-lateral orbital rims and lower forehead, advancement or alteration (eg, plagiocephaly, trigonocephaly, brachycephaly), with or without grafts (includes obtaining autografts)

The procedure described by CPT® Code 21175 involves the surgical reconstruction of the bifrontal region, specifically targeting the superior-lateral orbital rims and the lower forehead. This operation is primarily performed to correct various skeletal deformities, which may include conditions such as plagiocephaly, trigonocephaly, and brachycephaly. These conditions are characterized by abnormal head shapes resulting from premature fusion of skull sutures, leading to asymmetrical or misshapen skulls. The reconstruction aims to restore normal anatomical structure and function, enhancing both aesthetic appearance and cranial integrity. During the procedure, the surgeon may utilize bone grafts, which are typically harvested from the patient's own body, such as the hip, rib, or skull. This autologous approach minimizes the risk of rejection and complications associated with foreign materials. The surgery is performed under general anesthesia, ensuring the patient is completely unconscious and pain-free throughout the operation. To access the surgical site, the physician makes incisions in strategic locations, such as the eyelid or scalp, allowing for optimal visibility and manipulation of the underlying bone structures. The bones are then carefully reshaped and repositioned to achieve the desired contour. If bone grafts are indicated, they are meticulously placed to augment the forehead or orbital rim, providing additional support and structure. To secure the bones in their new positions, various fixation devices, including wires, plates, and screws, may be employed. Finally, the incisions are closed, completing the surgical intervention.
