CPT® Code 31081

Obliterative frontal sinusotomy, as described by CPT® Code 31081, 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, complications arising from previous surgical interventions, or conditions such as mucopyocele. The technique involves a coronal incision, which is made along the hairline, allowing access to the frontal sinus without the use of an osteoplastic flap. The primary goal of this surgery is to obliterate the frontal sinus, effectively preventing the recurrence of sinus-related issues by removing the sinus mucosa and filling the sinus cavity with abdominal fat. This approach is particularly relevant for patients who have not responded to endoscopic treatments or have experienced late complications from prior open obliteration procedures. The procedure includes the use of a burr to access the sinus and the complete ablation of the mucosa, ensuring that the sinus is thoroughly treated to mitigate future problems.
