SURGICAL TREATMENT OF GLANDULAR ODONTOGENIC CYST IN POSTERIOR REGION OF MANDIBLE

Abstract

A 49-year-old male patient complained "I can’t chew on the swollen side" (according to patient information). The anamnesis revealed a slightly painful lesion with 5 years of evolution. The physical examination showed swelling, with both cortices expanding, approximately 3 cm, in a retromolar area on the right side of the mandible, covered by normal-looking mucosa. Imaging examination showed an intraosseous lesion with hypodense area associated to tooth 46 in retromolar region. Incisional biopsy followed by histopathological examination closed the diagnosis of glandular odontogenic cyst. The lesion was treated by enucleation followed by peripheral ostectomy. The 12-month follow-up showed no signs of recurrence at clinical examination, such as imaging tests. Although the glandular odontogenic cyst is a rare entity, it needs to be diagnosed and treated, since it may present an aggressive character to the gnathic bones.
