CPT® Code 31085

Obliterative frontal sinusotomy, as described by CPT® Code 31085, is a surgical procedure aimed at addressing issues related to the frontal sinus, particularly in cases where other treatments have failed. This procedure is less commonly performed today but may still be indicated for patients suffering from intractable frontal sinusitis, especially when previous endoscopic treatments have not yielded satisfactory results. It may also be necessary in cases of mucopyocele, which is a collection of pus within the sinus, or in the event of late complications arising from prior open obliteration procedures that were unsuccessful. The technique involves creating a coronal incision that extends from one ear to the other along the hairline, allowing for direct access to the frontal sinus. The procedure entails the removal of the frontal sinus mucosa and subsequent obliteration of the sinus cavity, typically using abdominal fat to fill the space, thereby preventing future complications associated with sinus disease. This approach is particularly relevant for patients who have not responded to less invasive treatments and require a more definitive surgical intervention to manage their condition effectively.
