CPT® Code 31080

Obliterative frontal sinusotomy, as described by CPT® Code 31080, is a surgical procedure aimed at addressing chronic frontal sinus conditions, particularly in cases where other treatments have failed. This procedure is less frequently performed today but remains relevant for specific indications such as intractable frontal sinusitis, mucopyocele, or complications arising from previous surgical interventions. The technique involves accessing the frontal sinus through a brow incision, which is strategically placed just below the eyebrow. This approach allows the surgeon to reach the sinus without the need for an osteoplastic flap, which is a more invasive technique that involves removing a section of bone. During the procedure, the surgeon creates an opening in the medial floor of the sinus using a burr, which is then enlarged to facilitate the use of surgical instruments. The frontal sinus mucosa is meticulously elevated and completely removed, often with the assistance of an endoscope to ensure precision. Following the ablation of the mucosa, the sinus ostium is plugged with materials such as cellulose, and the cavity is obliterated by filling it with abdominal fat, effectively preventing future complications associated with sinus disease.
