Abstract
We performed fenestration of the maxillary sinus in 27 pediatric patients (49 sinuses) with chronic sinusitis who had not responded to conservative therapies (medications, irrigation and etc, ). Nasal polypectomy or ethomoidectomy was added in some patients. The symptoms improved in 70.4% of the patients and did not improve in 29.6%. The radiological examintions showed 61.2% of improved cases and 38.8% of failed ones. On overall evaluation (symptoms plus radiological findings), 59.2% of the cases were successful and 40.8% were unsuccessful. The therapeutic efficacy was lower in patients of younger ages and the degree of the improvement was higher with the time after the operation. The sinus window was patent in 42 sinues (85.7%) and closed in 7 sinues (14.3%). Mean postoperative period in the patent cases was 18.4 months.
