CPT® Code 61333

The procedure described by CPT® Code 61333 involves the exploration of the orbit using a transcranial approach, which is a surgical technique that allows access to the orbit through the skull. This approach can be executed by either removing a section of the frontal bone while preserving the orbital rim or by removing both the frontal bone and the supraorbital arch. The primary purpose of this procedure is to gain access to the superomedial aspect of the orbit, particularly for addressing lesions or defects located at the orbital apex, optic canal, or those that involve both the orbit and adjacent intracranial structures. The surgical process begins with a bicoronal incision, which is made across the scalp, allowing for the reflection of the scalp to expose the underlying structures. The procedure requires careful manipulation of the frontal lobe and the dura mater, ensuring that the surrounding tissues are preserved as much as possible. The removal of the lesion is performed with precision, ensuring that a margin of healthy tissue is included to minimize the risk of recurrence. After the lesion is excised, the surgical team reconstructs the orbit and secures the frontal bone back in place, followed by the repair of the soft tissues and skin. This complex procedure necessitates a thorough understanding of cranial anatomy and meticulous surgical technique to ensure optimal outcomes for the patient.
