ABSTRACT
Objective: To summarize the experience of repairing or al and maxillofacial defects with radial forearm free flap. Methods: The clinical records of 110 cases received oral and maxillofacial reconstruction with radial forearm free flap were analyzed.Results: Forearm free flap healed well in 10 5 out of the 110 cases.with the overall success rate of 96.4%.Failure was in 4 c ases of cancer.One patient died from cerebral infarction 19 days after operation .Post operation infection did not result in the necrosis of the flaps because o f corresponding treatment in 5 cases.Conclusion: The radia l forearm free flap characterized by the anatomical consistency,easy fold, ideal thickness, flexibility and long pedicle, is feasible in the reconstruction of soft tissue defects in oral and maxillofacial region.
ABSTRACT
An experimental study of vascularized and nonvascularized free bone-grafts for mandibular defects in dogs was conducted.The different bone healing process was observed by histological study.The results show that with 3 cm-length bone graft either vascularized or nonvascularized its healing process is similar.Both bones of donor and receptor have osteogenic activity.This process is similar to that of fracture healing.
ABSTRACT
The tongue and its surrounding structures have special anatomical and functional characters and how to restore its shape and function after glossectomy (especially total glossectomy) still remains a difficult problem. The authors devised a new method of repair by using a forearm free flap with results in 16 out of 17 patients. The selection and shaping of the flap, the evaluation of the recipient site and its blood vessels, the prevention of the oral infection,the monitoring of the circulatory status of the flap and the evalution of the operative result were discussed.
ABSTRACT
This paper presents one case of total glossectomy and six cases of subtotal and partial glossectomy with transplantation of free forearm flaps to repair and reconstruct tongue defects.In this series, the operation proved successful in six cases, but failed in one only.The operation achieved the desired contour and function of the tongue,The authors have accordingly attempted a new procedure of glossal reconstruction. Prospects concerning improvement of the technique are discussed.
