A sinonasal fungus ball is extremely rare in the frontal sinus (FS), as the FS is located on the anterior cranial floor and closely proximal to the orbit. The anatomical location and morphology of the FS make it difficult to remove the fungal mass, and surgery is required to remove the fungal mass and open the FS ostium. Given that fungal infections may recur due to postoperative stenosis of the FS ostium, the surgical approach should be thoroughly reviewed preoperatively. We herein report a rare case of a sinonasal fungus ball of the right FS in a 71-year-old man treated with Draf type IIb surgery. For FS fungus balls, the surgical approach to the FS should be considered based on a preoperative imaging diagnosis. In the present case, removal of the fungal mass by shaving enough bone from the FS floor seemed to be able to cure the disease without recurrence.
