Abstract

Background: In developing countries, many diagnosed cases of ameloblastoma (AB) have a significant delay in receiving treatment  because of patient factors and healthcare facility constraints.


Objectives: The radiologic progression of ABs with delayed treatment was analysed using panoramic radiographs and cone-beam  computed tomography imaging.


Method: Histopathologically confirmed cases of AB with follow-up radiographs indicating no treatment were retrospectively reviewed  over a study period of 10 years. Fifty-seven cases with 57 initial and 107 follow-up radiographs were included. Each follow-up radiograph  was analysed for changes in borders, locularity, effects on surrounding structures and lesion size.


Results: There was a general increase  in poorly-demarcated lesions, with seven cases transforming from an initial unilocular to a multilocular appearance. At follow-up, there  was an increase in cortical thinning and cortical destruction. Ameloblastomas presented with a three-fold increase in average size from  the initial to follow-up visits. Regression analysis showed a statistically significant relationship between lesion duration and length (p =  0.001). A statistically significant relationship existed between duration and overall lesion dimensions when only the first and last  observations per patient were used (p = 0.044).


Conclusion: Considering the aggressive nature and unlimited growth potential, ABs with delayed treatment may show extensive growth, complicating their eventual management.


Contribution: This study aimed to raise  awareness of the importance of the timeous management of patients with AB by highlighting the detrimental effects of delayed  treatment.
