Unilateral patent nasopalatine duct: a case report and review of the literature.
A 15-year-old white female sought our institution complaining of a chirping noise during speech and swallowing. The noise was spontaneous, perceptible, and enhanced when hard suction on the anterior palate was performed. The patient reported no trauma, infection, or other clinical feature related to the noise. Clinical examination showed 2 small grooves on both sides of the midline, lateral to the incisive papilla. The left groove was visually deeper. Careful probing with a gutta-percha cone revealed the existence of a communication on this side extending from the mouth to the nasal cavity, which was confirmed clinically and radiographically. Probing was not possible on the right side. The diagnosis was unilateral patent nasopalatine duct, which was surgically treated. We report here a new case of patent nasopalatine duct and also present a review of the pertinent literature.
