Maxillary sinus mucocele presenting as a late complication of a maxillary advancement procedure

This is the authors' abstract. We don't add key points for this paper.

Paranasal sinus mucoceles are benign, locally expansile cyst-like masses that are filled with mucus and lined with epithelium. Less than one per cent of them involve the maxillary sinus. Most of these are late complications of a Caldwell Luc procedure. A case is presented of a 31-year-old woman with a maxillary sinus mucocele who had undergone a Le Fort I maxillary advancement procedure 15 years previously - a complication never previously reported.
