In order to clarify that marsupialization is effective in the treatment of cystic ameloblastoma, 35 cases of mandible ameloblastoma treated by means of marsupialization were examined clinically, radiologically and histopathologically.
The age of the patients ranged from 4 to 80 years (average 24 years) . In 31 cases (88.6%), a reduction of lesion was found clinically and radiologically between 2 months and 2 years 4 months after marsupialization and in 4 cases no reduction was found.
As for the relation between the macroscopic findings and treatment result, most of the lesions with smooth cyst wall reduced soon after the operation. About half of the lesions with smooth and rough cyst wall reduced wholly, but the other half reduced only partially. All four lesions with a rough cyst wall (granular type) didn't reduce but grew into the lumen of the cyst.
The lesions of the squamous cell type and large follicular type reduced distinctly. As for the lesions of the plexiform type, some lesions reduced but the others grew.
When some tretment has been necessary after marsupialization, minimal resection of mandible was satisfactory in most cases.
From these results, it is suggested that marsupialization is effective in the treatment of cystic ameloblastoma.
