CPT® Code 31225

The procedure described by CPT® Code 31225 refers to a maxillectomy performed without orbital exenteration. A maxillectomy is a surgical procedure that involves the removal of the maxilla, which is the upper jawbone that also forms part of the orbit and the nasal cavity. This type of surgery is primarily indicated for patients with malignant tumors located in the maxillary sinus, which is the cavity situated within the maxilla. In cases where the tumor has invaded the periorbital region, a more extensive procedure known as orbital exenteration may be necessary; however, CPT® Code 31225 specifically denotes a maxillectomy that preserves the orbital structures. During the procedure, the surgeon gains access to the maxillary sinus through either a lateral rhinotomy, which is an incision made on the side of the nose, or an intraoral approach via the canine fossa, depending on the tumor's location. The surgical team meticulously resects both the mucosa and the bone of the maxillary sinus to ensure complete removal of the tumor. Following the resection, the orbital floor is reconstructed to maintain the structural integrity of the orbit. This procedure is critical for managing malignancies in the maxillary region while aiming to preserve surrounding anatomical structures, particularly the orbit, which houses the eye and its associated tissues.
