Abstract

Background and Objectives: The dentigerous cyst is a developmental odontogenic cyst which originates through alternations of the reduced enamel epithelium in an unerupted tooth. The purpose of this study was to investigate the clinical features of dentigerous cyst, especially those involving the maxillary sinus.
Materials and Methods: Retrospective survey of dentigerous cyst was undertaken at the Department of Otorhinolaryngology-Head and Neck Surgery from January 1985 through June 2008.
Results: There were 22 dentigerous cysts in this study. They occur over a wide age range with a peak frequency in the second to fourth decades. Every cyst was related to a supernumerary tooth. Facial swelling was the most common presenting symptom. Radiolucent and unilocular lesion was a radiologic characteristic of dentigerous cysts. Nineteen cases were treated by traditional Caldwell-Luc approach. Endoscopic marsupialization was used in three cases.
Conclusion: Dentigerous cysts involving the maxillary sinus usually present as facial swelling. Radiologic examinations and clinical features can aid in diagnosis. Complete surgical enucleation can reduce recurrence. Endoscopic marsupialization should be considered carefully as the another option of treatment for dentigerous cyst of the maxillary sinus in selected case.
