Massive Ameloblastoma and Reconstruction with Free Fibular Graft

Aims: To report a case of massive ameloblastoma in mandible with wide excision and reconstruction with free vascularized fibular graft and titanium plate.

Case Description: A 49- year-old male patient complained right facial mass since 5 years ago. Patient underwent right hemimandibulectomy with general anesthesia and pathologic examination revealed folliculare ameloblastoma. The large defect after resection reconstructed with free fibular graft. Fibula was osteotomised and resembled with mandible shape and reconstructed by plate with intact pedicle. Care was taken to protect the periosteal branch of the peroneal artery before performing an osteotomy. Shaping of the resected fibula was done according to the preoperative template. A titanium miniplate with locking screws was used to secure the osteotomized fibula and the mandible. To secure the airway, we performed tracheostomy. Followup after operation, patient still got a defect facial asymmetry in right mandible.

Discussion: Ameloblastoma is histologically benign but locally aggressive tumor originating from odontogenic epithelium. After hemimandibulectomy, reconstruction continued with microvascular free fibular graft and titanium plate. Osteotomies were performed with the pedicle still attached.

Conclusions: Free vascularized fibular graft with titanium plate is preferrably reconstruction option for large defect after wide excision of mandibular ameloblastoma.
