Prevention of Lateral Synechia Formation with Silastic Sheet in the Endoscopic Sinus Surgery / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Lateral synechia formation between the middle turbinate and the lateral nasal wall is one of the most common complications in endoscopic sinus surgery. Unstable and floppy middle turbinate occurs not infrequently and it may make meticulous postoperative dressing difficult during healing period, and consequently increases the risk of synechia and recurrence of sinusitis. The aim of this study was to investigate whether insertion of the silastic sheet in the middle meatus can effectively prevent the synechia formation. SUBJECTS AND METHOD: Twenty eight patients (31 sides including 3 bilateral cases) with unstable and floppy middle turbinate occurred during endoscopic sinus surgery were enrolled in this study. The silastic sheet was designed in fan-shape and inserted between the middle turbinate and the lateral nasal wall. The silastic sheet was secured to the caudal septum and removed 2 to 3 weeks after the operation. We performed a follow-up study for 5 months and investigated the occurrence rate of synechia. RESULTS: The success rate of our method was 90.3% and synechia in the middle meatus developed in 3 of 31 sides (9.7%). Although synechia between the middle turbinate and nasal septum occurred in 4 sides, the patients did not complain of olfactory disturbance. CONCLUSION: The results of this study suggest that insertion of the silastic sheet in the middle meatus can be a useful method in the prevention of lateral synechia formation when unstable and floppy middle turbinate has developed during endoscopic sinus surgery.
