Abstract

Aim: To review the management and reconstruction of ameloblastoma of mandible in different age groups over a period of 11 years.

Methodology: This retrospective study includes 51 cases operated in the Maxillofacial Unit, Bhagwan Mahaveer Jain Hospital, Bangalore, from the year 2007 to 2017. The data of these patients were collected to record demographic data such as age, gender with site of tumour and type of reconstruction after resection, follow-up period and incidence of complications. This study evaluated the outcome in terms of aesthetics, function and choice of reconstruction in different age groups.

Results: Most patients were of 21-40 age group. 37 (72.5%) were found to be unicystic ameloblastoma. 41 (80.3%) patients underwent reconstruction following the resection. There was a change in trend seen over a period of time with free grafts and reconstruction plate being historical, except in special situations like old age and unfit patients. According to one-way ANOVA and Tukey's post hoc analysis, free flaps were known to take a longer duration (mean = 503 min) compared to other modes of reconstruction. However, free grafts and free flaps were demonstrated to have a good facial contour and speech with most cases dentally rehabilitated with implants. Among the complications, 1 (16%) case with reconstruction plate showed screw loosening, 2 (28%) cases with free grafts showed graft exposure, and 1 (3.5%) case with free flap had venous congestion, making free flaps the most reliable option.

Conclusion: Free fibula is the gold standard of mandible reconstruction, but depending on age, medical condition, economic status and size of the defect other modes of reconstruction can be chosen with the acceptance of suboptimal results.
