Clinical observation of maxillary cyst with endoscopic marsupialization in nasal / 中国内镜杂志

ABSTRACT

Objective To explore the feasibility and evaluate its efficacy of transnasal marsupialization of maxillary cyst under nasal endoscope. Methods 15 cases of maxillary cyst were treated by endoscopic marsupialization in nasal. According to the situation of maxillary cysts, the fenestration of bottom nasal was opened in 6 cases, the fenestration of inferior nasal meatus was opened in 7 cases and inferior nasaI meatus was opened through the prelacrimal duct recess in 2 cases under the nasal endoscope. With partial removal of the cyst wall, the cyst and maxillary sinus was fused into a cavity if necessary. This ensured nasal drainage through the cyst cavity and nasal cavity or maxillary sinus. Results The operations of the 15 patients were success without complications. All patients were followed up for 6 to 24 months after operation. Operation cavity to complete epithelization in 2 to 3 months, the cyst cavity drained well with no recurrence. Conclusion Endoscopic marsupialization in nasal is a feasible alternative for management maxillary cyst. It makes the procedure simple, less traumatic, quick recovery, definite curative effect and low recurrence rate.
