Here, we present a case involving a 64-year-old man with a recurrent orbitofrontal cholesterol granuloma treated by the Modified Lothrop (Draf III) procedure. The patient, who had a history of trauma and previous sinus surgery, presented with chief complaints of nasal congestion, olfactory impairment, and diplopia. We suspected chronic sinusitis; computed tomography showed a soft-tissue shadow extending from the bilateral frontal sinuses to the ethmoid sinuses, with a cyst in the right orbitofrontal region. We performed endoscopic surgery for removal of the mass, and histopathological analysis of the resected specimen confirmed a diagnosis of cholesterol granuloma. The lesion recurred 2\u2009months later, and we performed revision surgery using the Modified Lothrop or Draf III procedure. The patient showed no relapse at the 5-year follow-up. These findings suggest that the Draf III procedure is an effective surgical treatment for cholesterol granulomas.
