Abstract
Background:Ameloblastoma is the second most common odontogenic tumor. It shows a locally aggressive behavior, with a high level of recurrence. Wide resection of the jaw is recommended for treatment of ameloblastoma. However, radical surgery causes an abnormal mandibular movement, facial asymmetry, and masticatory dysfunction.Methods:Three cases of different types of ameloblastoma is presented, with different reconstruction techniques including Non-Vascularized Bone Graft (NVBG), Osteocutaneous Fibula Free Flap (OFFF), and Deep Circumflex Iliac Artery flap (DCIA).Results:In all three cases the tumor site was successfully reconstructed to obtain very good esthetic results as well as functional oral rehabilitation with implants and fixed prosthetics for optimal masticatory function.Conclusion:For reconstruction of the mandible, we prefer bone grafts from the iliac crest. The natural curvature and variable bone height offer a very good reconstruction of the defect.
Highlights
Ameloblastomas represent approximately 1% of all tumours and cysts of the maxilla and mandible, and 10% of all odontogenic mandibular tumours
Several strategies have been used for the treatment of ameloblastoma of the jaw, including surgical resection, conservative treatment, enucleation, and bone curettage [6, 9]
The importance of wide surgical resection to minimize the risk of recurrence has been discussed previously in the context of a randomized trial involving 48 patients [10]
Summary
Ameloblastomas represent approximately 1% of all tumours and cysts of the maxilla and mandible, and 10% of all odontogenic mandibular tumours. The most common site of ameloblastomas is the angle and the body of the mandible. These tumours are characterized by slow growth and painless symptoms, which may delay an early diagnosis and cause facial deformity, increased tooth mobility, and ulceration of the oral mucosa [1]. Ameloblastoma is the second most common odontogenic tumor. It shows a locally aggressive behavior, with a high level of recurrence. Wide resection of the jaw is recommended for treatment of ameloblastoma. Radical surgery causes an abnormal mandibular movement, facial asymmetry, and masticatory dysfunction
