title: [Maxillary mucocele after an orthognathic surgery: case report].
abstract: Mucoceles are not often found in the maxillary sinus, and is a rare surgery complication, in this case, orthognathic. This review describes a mucocele that partially occupies the right maxillary sinus, causing a chronic nasal obstruction. This is the case of a 44 year-old female patient, which after 12 years of several orthognathic surgeries, presents facial pain and right nasal obstruction. The paranasal sinus computed tomography reveals a mass with liquid content that occupies the lower part of the right maxillary sinus and compromises the right nasal cavity. The patient was treated with an intranasal marsupialization and a middle meatotomy with endoscopic nasal approach. Evolution was satisfactory two years after the intervention.
