Conservative treatment of a unicystic ameloblastoma by marsupialization with a favorable response: A case report and review of the literature

Esin Demir, Omer Gunhan


Ameloblastoma is a benign tumor of odontogenic epithelium which is slow growing, locally invasive,
expansive that may result with asymmetries of the face. Conservative treatment of odontogenic
tumors with marsupialization is not common but can be done successfully in those with cystic
pattern. The aim of this case and literature review is to propose marsupialization as an initial
procedure for its treatment. We have presented a case of an ameloblastoma involving 56‑year‑old
male patient. Orthopantomography and computed tomography showed the lesion extended
between the right molar region and left molar region of mandible with both buccal and lingual
expansion and root resorptions. On clinical examination, expansions of mandible and slight tooth
mobilities were seen. An incisional biopsy was carried out and histopathologic examination revealed
ameloblastoma although clinical features of lesion were more suggestive of cyst. Our case was treated
by obturator marsupialization with a good healing. This case and review of the literature discusses
the available treatment option according to macroscopic features of jaw lesions and emphasizes
on the importance of the most conservative treatment option. Conservative treatment preserves
integrity of bones while radical treatment can leave major cosmetic and functional sequelae such
as pathologic fractures, complication with reconstruction plates.
