Objective:
To explore the method of clinical application and the efficacy of free fibula osteomyocutaneous flap in one-stage reconstruction of transmidline bilateral mandibular defect caused by giant neoplasms.
Methods:
From july 2000 to october 2002, transmidline bilateral mandibular defects caused by ameloblastoma (4 cases) and gingival carcinoma (2 cases), according to the character of defects, were reconstructed with free fibula osteomyocutaneous flaps. Peroneal artery and vein were used as vascular pedicle, the fibula was reshaped, and micro-titanium plates were used in rigid fixation between fibula and residue of bilateral mandible. Microvascular anastomoses were carried out between peroneal artery/vein and small artery/vein in neck.
Results:
Six free fibular osteomyocutaneous flaps survived well. Follow up duration ranged from 6 months to 2 years, the lower face appearance recovered well, occlusion relationship were normal, all patients were satisfactory with appearance and chewing function after repair of removable denture.
Conclusion:
Free fibular osteomyocutaneous flap is a favorable material in the reconstruction of transmidline bilateral mandibular giant defect. The blood supplement of fibula is offered both by segmentral periosteum and nutrient artery from bone marrow, It is greatly benefit to reshaping as arched mandible.
