Orbitocranial approach to anterior cranial fossa, extradural, including supraorbital ridge osteotomy and elevation of frontal and/or temporal lobe(s); without orbital exenteration

The CPT® Code 61584 describes a surgical procedure known as the orbitocranial approach to the anterior cranial fossa, which is performed extradurally. This approach is utilized primarily for accessing the anterior cranial fossa to address various medical conditions, including the resection of malignant tumors, treatment of infectious diseases, and management of traumatic injuries affecting the orbit and paranasal sinuses. Notably, this procedure is conducted without orbital exenteration, which is the complete removal of the periorbita, eyeball, eyelids, and surrounding skin. The surgical technique involves a careful incision of the scalp, which is strategically placed along the inferior border of the zygomatic arch and extended in a curved manner to meet the contralateral midpupillary line behind the hairline. This meticulous approach allows for the elevation of the frontal and/or temporal lobes while preserving the integrity of the orbit. The procedure is complex and requires a thorough understanding of the anatomical structures involved, as well as the surgical techniques necessary to achieve optimal exposure and access to the targeted areas of the cranial fossa.
