CPT® Code 31230

The procedure described by CPT® Code 31230 refers to a maxillectomy performed with orbital exenteration in an en bloc fashion. A maxillectomy involves the surgical removal of the maxilla, which is the upper jawbone, and is typically indicated for patients with malignant tumors located in the maxillary sinus. In cases where the tumor has invaded the periorbital region, the procedure may necessitate the removal of orbital structures, leading to an orbital exenteration. This radical approach is crucial for ensuring complete resection of the tumor and minimizing the risk of recurrence. The procedure can be approached through a lateral rhinotomy or an intraoral route, depending on the tumor's location. The surgical team meticulously removes the mucosa and bone of the maxillary sinus, ensuring that all affected tissues are excised. Following the maxillectomy, the orbital floor is reconstructed to restore anatomical integrity. In the case of en bloc orbital exenteration, the surgery involves a comprehensive removal of the eyeball and all orbital contents, which is performed through a full-thickness incision around the eye. This detailed approach is essential for addressing extensive malignancies that compromise both the maxillary and orbital regions.
