Isolated Osteoma of the Ascending Process of the Maxilla.

ABSTRACT

BACKGROUND: Osteoma, the most common benign tumor of the paranasal sinuses, most commonly originates within the frontal sinus, followed by the ethmoid, the maxillary sinus, and finally sphenoid. Only 2 cases of osteomas of the nasal bones were previously reported. This study describes the first reported osteoma of the ascending process of maxilla and describes its management. METHODOLOGY: A 20-year-old man was presented with left painless hard nasal swelling. Computed tomography (CT) scan showed well-circumscribed hyperdense bony mass originating from the outer surface of the left ascending process of maxilla. This mass was removed through lateral nasal incision. RESULTS: The mass was histopathologically proved to be compact osteoma and was removed totally with no reported operative or postoperative complication. CONCLUSIONS: A case of osteoma of ascending process of maxilla was reported and could be safely removed. This directs surgeon attention to osteoma as a cause of nasal bone swelling because early diagnosis allows easy and safe removal of the osteoma.
