Intrabony ameloblastoma of the jaws. An analysis of 147 Thai patients.
In this study, 147 cases of intrabony ameloblastoma from the files of our departments were reviewed. Clinical findings showed an average age of 31.6 years and a sex ratio of 1.1:1. The average duration of the tumour was 2.7 years. The majority of the tumours, 93.9%, occurred in the mandible with 36.1% of the cases found in the molar area. Radiographically, 62.7% of the lesions were polycystic. Histopathologically, 49.0% had a follicular pattern. There seems to be no direct correlation between the histologic patterns and the radiographic appearances of the tumors but there is a slight indication that both monocystic and polycystic types tend to have the plexiform pattern, while the soap-bubble type tends to have the follicular pattern.
