Objective: To study the correlative factors of synechiae following endoscopic sinus surgery and their clinical significance.
Methods: Thirty-two cases (47 sides) of surgical cavity synechiae occurred in 338 (513 sides) endoscopic sinus surgeries were analyzed. The types of synechiae and correlative factors such as pathological features, primary ailment severity, pneumatization of middle turbinate, middle turbinate management, surgical procedures and follow-up management were analyzed.
Results: 1. The synechiae occurred in 9.16% of cases. 2. The synechiae occurred successively as: ethmoid sinus cavity synechiae and occlusion, synechia between middle turbinate and lateral nasal wall, middle turbinate synechiae with nasal septum, inferior turbinate synechiae with nasal septum. There was no synechiae between inferior turbinate and middle turbinate. 3. Synechia frequently occurred in patients with inflammatory lesions, severe primary ailment, pneumatization of middle turbinate, pathological middle turbinate, improper surgery and follow-up management and delayed follow-up.
Conclusion: It is very important to fully recognize every correlative factors of synechiae pre-operatively in order to reduce synechiae. In addition, improvement of surgical technique, appropriate management of middle turbinate, in time follow-up and separation of synechiae timely are also indispensable to successful surgery.
