A CASE REPORT OF MAXILLARY CYST ; ONE CASE OF ANEURYSMAL BONE CYST AND TWO CASES OF DENTIGEROUS CYST

There are various type of maxillary cyst. We treated a one case of aneurysmal bone cyst and two cases of dentigerous cyst of maxilla. Aneuryemal bone cyst is still an uncommon jaw lesion and is regarded as a nonneoplastic lesion consisting of cystic lesion consisting of cystic cavities with non-endothelial-lined space. Although its pathogenesis is controversial, radiographic and histologic feature is characteristic. In this case, a cystic lesion which was clinically diagnosed as a traumatic bone cyst but postoperative biopsy showed as an aneurysmal bonw cyst was developed around the apices of left central incisor and lateral incisor of maxilla, and its cause is suggested to be a trauma. Dentigerous cyst is fomed in relationship to a normal permanent tooth, but rarely it may be associated with a supernumerary tooth. In this case, a large dentigerous cyst developed around the impacted maxillary third molar encroached upon maxillary sinus and almost entirely obliterated it. One case of dentigerous cyst was found around the maxillary supernumerary impacted tooth which was located beneath the apices of left central incisor and lateral incisor. Under the local anesthesia, an aneurysmal bone cyst was thoroughly curetted and primary closure was performed. Under the general anesthesia, a dentigerous cyst which was developed maxillary third molar was enucleated with a combination of Caldwell-Luc operation and the other was enucleated with primary closure. Post-operative follow-up check revealed a good prognosis.
