[Post operative Caldwell-Luc procedure maxillary cyst: Report of a case].

Rare complication of radical surgery (Caldwell Luc procedure) of the maxillary sinus, maxillary cyst can occurred several years after. We describe the case of a patient 56 years old, who came to our consultationfor repeated pain in the right maxillary region with moderate facial asymmetry. In her history we noted a previous sinus surgery (Caldwell Luc) more than 10 years before. The imaging showed an expansive process filled with proteinic tissue of the posterior wall of the maxillary. With the history of the former surgery, we suspected the existence of a mucocele. She underwent an endonasal surgery and the pathological examination of the specimen revealed an intra osseous cyst lined with ciliated respiratory type mucosa post surgery of the maxillary sinus. The diagnosis of a maxillary cyst complicating a Caldwell Luc was established based on the results obtained with the clinico-radiological and pathological results.
