A persistent oronasal sinus tract of endodontic origin

J Endod. 1989 Mar;15(3):132-4. doi: 10.1016/S0099-2399(89)80135-9.

Abstract

Extraoral sinus tracts of endodontic origin may be confused with a wide variety of diseases. Although they may be located in a variety of sites on the face and neck, once diagnosed the treatment is relatively simple and successful. Endodontic therapy is the treatment of choice in these cases; however, periapical surgery may occasionally be required. A case of persistent oronasal sinus is described in which healing occurred only after surgical removal of the involved lesion.
