Abstract:
BACKGROUND: Postoperative maxillary cyst(POMC) occurs as a delayed complication following Caldwell-Luc(C-L) operation. Revisional C-L operation has been preferred by most surgeons. Recently, marsupialization with intranasal endoscope has been increased in the management of POMC. OBJECTIVES: The aim of this sutdy was to evaluate the clinical characteristics of POMC and the relationship between location of the cyst on axial PNS CT and surgical approaches. MATERIALS AND METHODS: The 24 patients(26 sides) were reviewed from 1990 to 1996. According to the classification methods of Nakamura, sixteen cases were located in medial, two cases in posterolateral and eight cases in anterolateral of the maxilla. RESULTS: The 22 cases including medial(16 cases), posterolateral(2 cases) and Anterolateral(4 cases) types were treated with marsupialization via intranasal endoscopic approach, 4 of 8 cases which were located in anterolateral type were treated with Caldwell-Luc approach. There was no complication and showed improvement in all patients. CONCLUSION: We think that the classification methods of cyst was useful in deciding surgical approaches. The endoscopic intranasal marsupialization is an effective therapeutic method of POMC especially in medial and posterolateral types.
