In recent years, paranasal sinus mycosis has been increasing. We have experienced and present a case of the maxillary sinus mycosis.<BR>A 24-year-old man visited our hospital with a chief complaint of pain in the right upper third molar region. Radiograph at his first visit revealed that tooth 13j was completely impacted and also disclosed a radiopaque area approximately 2 mm in diameter in the middle of the right maxillary sinus. We diagnosed odontogenic sinusitis and mycosis of the right maxillary sinus suspect. Tooth j was extracted on the same day, and the extraction fossa was healed. Around January 5, 1991, he suffered spontaneous pain in the right buccal region, leading the patient to return to the hospital. Waters' view and facial CT revealed a high-density spot suggestions a fungus ball in the right maxillary sinus. On January 29, 1991, intraoperative histopathological examination under general anesthesia revealed a fungus-ball (later diagnosed as mucormycosis) in the right maxillary sinus. Radical surgery was performed on the maxillary sinus. Amphotericin B was administered in oral doses and gargle on the day after surgery.<BR>The patient's course has been good for 3.5 months after the surgery, and there have been no signs of recurrence.
