Clinicostatistical Study of Ameloblastoma Treatment.

Abstract

The purpose of this study was to investigate the treatment of 190 cases of ameloblastoma in our department from 1966 to 1994. The statistical results with regard to age, sex and region agreed with those of other investigators. Thirty-five of 43 (81.4%) cases underwent enucleation in 1960s, but the sixteen of 27 (59.3%) cases underwent partial resection of mandible in 1990s. The defect of mandible was reconstructed with iliac bone grafting since 1968, grafts with a mixture of iliac blocked bone and PCBM (particulate cancellous bone and marrow) have been used since 1975. Grafting of the inferior alveolar nerve with the great auricular nerve to the defect has been performed in our department since 1977. Recently, technique involving pull-through of the inferior alveolar nerve bundle has been used in our department. When the reconstruction method for the mandible and nerve has been established, it becomes possible to operate radically and positively. Recurrence occurred in 17 cases after the primary enucleation. It is thought that the primary treatment of ameloblastoma must be as radical as possible. It appears to be necessary to observe progress and perform follow-up in cases of ameloblastoma for more than ten years, because there was one recurrence at 9 years and 4 months after the first operation. In fact, three quarters of our cases were lost to follow-up. Such losses can problems in confirming recurrence and responding rapidly.

Ameloblastoma resection with immediate rib reconstruction: addressing the problem of mandibular angle and central bone bulk

“…Although others have been able to preserve this nerve and even graft it for reconstruction, so far we have not been able to duplicate their good results. 6 Because of the large size of tumours in our series, the nerve has regularly been sacrificed on the involved side.…”

Ameloblastoma: An Updated Narrative Review of an Enigmatic Tumor

“…The male: female ratio was 1.5:1. Hatada et al from Japan documented a mean age of 35 years with a male: female ratio of 1.6:1, with about 93% of tumors located in the mandible [18]. In a study on 52 cases of ameloblastomas from India, the predominant age of presentation was the third to fourth decades with a male preponderance; and the most common site was the lower jaw, especially the posterior aspect, both for new and recurrent cases [19].…”

The Epidemiology, treatment, and complication of ameloblastoma in East-Indonesia: 6 years retrospective study

“…Lu et al ( 4 ) studied the Chinese populations and showed a mean age of 31.4 years with a 1.5:1 male : female ratio and 90.8% of the tumors were in mandible. A study by Hatada et al ( 5 ) on the Japanese population showed a mean age of 34.7 years with a 1.6:1 male : female ratio and 92.6% was located in the mandible. There was no study found in Indonesian population.…”
