This week I have a case of a nasopalatine canal cyst. This is also referred to as an incisive canal cyst and/or a nasopalatine duct cyst. This case was found on a pantomograph of an edentulous patient. The patient presented for complete dentures and was asymptomatic. There is a well-defined radiolucent entity in the anterior maxilla. Due to the large size of the lesion, a cone beam CT was performed. The cone beam CT showed the well-defined ovoid radiolucent area with anterior displacement of the facial cortical plate. There was also a discontinuity of the facial and palatal cortical plates.
(Look closely as it is difficult to identify)
