The procedure described by CPT® Code 61332 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 performed in two ways: either by removing 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 procedure begins with a bicoronal incision, which is made across the scalp, allowing for the reflection of the scalp to expose the underlying structures. Subsequently, burr holes are drilled above the orbital rims to facilitate the removal of the frontal bone. The dura mater, which is the outermost layer of the meninges covering the brain, is carefully reflected to expose the floor of the frontal fossa. This meticulous approach ensures that the frontal lobe can be retracted safely, allowing for a clear view of the surgical field. The procedure culminates in the identification and biopsy of abnormal tissue within the orbit, which is crucial for diagnostic purposes. Following the exploration and biopsy, the surgical team reconstructs the orbit and secures the frontal bone back in place, ensuring proper healing and restoration of the anatomical structures.

The exploration of the orbit via a transcranial approach, as described in CPT® Code 61332, is indicated for various conditions that necessitate direct access to the orbit and surrounding structures. The following are the explicitly provided indications for this procedure:
The procedural steps for the exploration of the orbit using a transcranial approach are as follows:
Post-procedure care following the exploration of the orbit via a transcranial approach involves monitoring for any complications, such as infection or cerebrospinal fluid leaks. Patients are typically observed for neurological status and any signs of complications related to the surgery. Pain management is provided as needed, and instructions for wound care are given to ensure proper healing. Follow-up appointments are essential to assess recovery and to evaluate the biopsy results obtained during the procedure. The overall recovery time may vary depending on the extent of the surgery and the individual patient's health status.
