腓骨垂直牽引術應用於下顎骨重建-病例報告

Vertical Distraction Osteogenesis of Fibula Bone Flap in Mandibular Reconstruction-A Case Report

摘要


本篇報告一位十八歲女性,下顎骨因腫瘤切除,以腓骨皮瓣修復。因修復後的新齒槽骨(腓骨)與鄰接的原有自然齒槽骨有相當的高度差,所以採用修復後的新齒槽骨(腓骨)作垂直骨牽引增高術。在垂直牽引的過程中受到牽制,如固定骨板螺絲鬆脫、及移動骨片在牽引的引導方向中受到干擾等,以致與法達到預期的牽引效果。本文探討造成此次牽引過程中可能受到的原因及改善方式,提供大家作參考。

The reconstruction principle requires not only that esthetic profile be acquired, but also that oral function rehabilitation be obtained. So in order to maintain the mandibular continuity after tumor resection, the use of free vascularized bone flap is considered to be a treatment option. The fibula bone flap presents many advantages, but it does not offer sufficient bone height to restore the alveolar ridge after reconstruction when a dentate mandible is involved. The double barrel fibula technique and vertical distraction osteogenesis of fibular bone can solve this problem. In this article, we present an 18 years old female, who was a victim of central giant cell granuloma of the mandible, which was reconstructed by utilizing a fibula flap. During the 2-year postoperative follow-up, no tumor recurrence was noted. The patient and her family requested oral function rehabilitation. We used the vertical distraction osteogenesis method to increase the height of the fibular bone before implant placement of the dentate mandible (new mandible). This method is desirable from both functional and esthetic point of view for mandibular reconstructions.
