title: Protrusion of postoperative maxillary sinus mucocele into the orbit: case reports.
abstract: Maxillary sinus mucocele, which appears more than 10 years after Caldwell-Luc surgery, is very rare in the United States or Europe. However, it is very common in Japan. It is called "postoperative maxillary sinus mucocele" or "postoperative maxillary cyst." In this paper, postoperative maxillary sinus mucoceles, which protruded into the orbits, are reported. One patient, a 50-year-old man, underwent Caldwell-Luc surgery 31 years ago, and the other patient, a 61-year-old woman, underwent Caldwell-Luc surgery at the age of 18. The incidence of this disease, symptoms, diagnosis and treatment are discussed in this paper.
