Abstract
Statistical observation of 58 cases with postoperative maxillary cysts, which were treated surgically and conservatively at the department of otolaryngology of Saga Medical School from November 1981 to October 1984, was performed. The results are summarized as follows; 1) The age of the patients ranged from 23 to 69 years. The average age was 44.0 years. 2) The male to female ratio was 37: 21. No significant lateral preference of affected maxillary sinus was found. 3) The incubation period from the last surgical treatment to onset of the symptoms was an average of 17.7 years; the shortest was four months and the longest was 43 years. 4) Most of the patients complained of symptoms such as cheek swelling and/or pain, regardless of the number and site of the maxillary cysts. 5) It appears that ENT doctors should perform follow-up examinations on patients for three months after surgery in fear of the development of maxillary cysts.
