Recurrent Pott's Puffy Tumor Treated With Anterior Skull Base Resection With Reconstruction of the Anterolateral Thigh Flap.

Pott's puffy tumor (PPT) is a rare, life-threatening complication of frontal sinusitis that is treated with a combination of appropriate antibiotics and surgery for the removal of infected tissue. A 56-year-old man with recurrent forehead swelling was admitted and diagnosed with recurrent PPT. He had undergone endoscopic sinus surgery and pericranial abscess drainage. We planned to remove the infected tissue and bones and perform reconstruction with an anterolateral thigh (ALT) flap. Eight weeks after surgery, the patient showed no inflammation, and the antibiotics were discontinued. No recurrence was observed at 1 year and 7 months after surgery. Combined surgical and antibiotic treatment is effective for PPT. Reconstructive treatment can be chosen for refractory recurrent cases with intracranial complications. To our knowledge, this is the first report of PPT treated by anterior skull base resection with reconstruction using an ALT flap in an immunocompromised patient.
