Purpose:
To review the age of onset, gender, sites, pathologic types, operation methods and prognosis, and explore the internal relations in 108 cases of ameloblastoma.
Methods:
The patients were divided into 7 groups according to the age, and then the proportion, primary site, pathologic type, and recurrence rate of ameloblastoma in all groups were analyzed. The relationship among pathologic type, recurrence rate and primary site, as well as the relationship between operation methods and recurrence rate were evaluated.
Results:
In 108 patients, 61 patients were 20-39 years old (56.48%) with more men than women. 88 patients occurred in the mandible(81.48%). Follicular type accounted for 45.37%, and plexiform type accounted for 62.96%. The average recurrence rate of 108 patients was 32.41%, and recurrence was more often in patients over 50 years old. The postoperative recurrence rate of 65 patients treated by curettage was 43.08%, while it was 16.28% in 43 patients treated by radical correction. The recurrent rate was 34.69% in follicular type, 26.47% in plexiform type, and 28.57% in acanthoma type and granular cell type respectively.
Conclusions:
Ameloblastoma usually occurs in young men, more frequently in mandibular molar region, ramus and mandibular angle. Follicular type and plexiform type are the most common pathological types. Follicular type relapses more easily. Compared with curettage, radical surgery can reduce the recurrent rate.
