술후성 협부 낭종에 대한 임상적 분석: 10년의 경험

Objective: The aim of this study was to evaluate the clinical analysis of postoperative cheek cyst for past 10 years and causes of revision surgery. Subjects and Methods: The study design was a retrospective clinical series. We reviewed the medical records of 45 cases (43 patients: both cases in two patients) with postoperative cheek cyst who were diagnosed and treated from 1999 to 2009. Results: The patients underwent middle and/or inferior me- atal antrostomy with or without Caldwell-Luc operation. All patients were followed at least for more than 24 months after surgery, and revision surgeries were noted in 9 cases (20%). Of the 9 cases in revision surgery, the obstruction of inferior meatal antrostomy site in 7 cases and remained cyst from multiple septated cysts in 2 cases were showed. Conclusion: In order to avoid of revision surgery for postoperative cheek cysts, we should carefully review of paranasal computed tomography scan findings such as bulging state of the cyst into the inferior meatus and presence multiple septated cysts.
