Periorbital osteotomies for orbital hypertelorism, with bone grafts, is a surgical procedure aimed at correcting the abnormal distance between the orbits, a condition known as hypertelorism. This procedure involves the use of bone grafts, which are typically harvested from the patient's own body, such as the hip, rib, or skull. The surgery is performed through an extracranial approach, meaning that the incisions are made externally rather than through the cranial cavity. The physician accesses the orbits and the naso-orbital region through various incision points, which may include the lower eyelid, eyebrow, or maxillary vestibule. Once access to the orbit is achieved, specialized surgical instruments, including drills and saws, are utilized to create precise incisions in the orbital rims. During the procedure, portions of the nasal and ethmoidal bones may be excised to facilitate the repositioning of the orbits. After the orbits are correctly aligned, they are secured in place using wires, screws, and plates. The harvested bone grafts are then placed into the recipient beds to fill any defects resulting from the orbital repositioning. Finally, all incisions made during the procedure are meticulously closed to promote healing and minimize scarring.
