ABSTRACT

A case of nasal polyp arosing in the alveolar cleft in a patient with cleft lip and palate is reported. A 31- year old man visited a otolaryngologist because of a swelling at the right alar base. He was referred to our department for a clinical diagnosis of nasoalveolar cyst. Physical examination revealed a scar on the right upper lip following cheiloplasty and diffuse swelling of the nasal floor and gingiva. CT examination revealed a tumor measuring 30 X 40 mm in the alveolar cleft. MRI showed hypointensity on T1-weighted images and hyperintensity on T2- weighted images. A clinical diagnosis of a benign tumor was made, and the tumor was removed with the patient under general anesthesia. The histopathological diagnosis was a nasal polyp. No recurrence was observed after operation. Keywords: cleft lip and palate, nasal polyp, alveolar cleft.
