Abstract

Ameloblastoma is a benign neoplasm originating from odontogenic epithelium. It is the most common neoplasm in the jaws and is characterized by aggressive behavior and local invasion. Unicystic ameloblastoma (UA) has a unilocular feature in radiologic examination and a cystic feature histologically. Decompression and marsupialization are conservative method of treatment of large UA. The purpose of decompression and marsupialization are size reduction of the mass, which makes it easy to handle at total enucleation with protection of nerve damage and facial deformity. Here we report successful conservative treatment of extensive UA using decompression and marsupialization with a review of literatures.

• 

  Fig. 1 Dental panoramic view. Large radiolucent lesion including #35 is detected in the left mandible.

• 

  Fig. 2 Computed tomography (CT) view. Perforation of both side of the mandible is clearly detected. (A) Coronal view, (B) Axial view.

• 

  Fig. 3 Post operative dental panoramic view. A penrose drain is inserted into the mass.

  Fig. 4 CT view after 6 months follow-up. Perforation of mandible is not detected. (A) Coronal view, (B) Axial view.

• 

  Fig. 5 CT view after 8 months follow-up. Marked newly formed bone is detected. (A) Coronal view, (B) Axial view.

• 

  Fig. 6 The inferior alveolar nerve is protected with newly formed bone (arrow: inferior alveolar nerve).

• 

  Fig. 7 Microscopically, unilocular cyst is lined by thin epithelium with ameloblastic changes such as basaloid
