The fibula osteoseptocutaneous flap is a good option for reconstruction of three-dimensional composite maxillary defects. This flap provides both bone and soft-tissue reconstruction and allows osseointegrated dental implantation, either simultaneously or in a second-stage procedure. Simultaneous placement of osseointegrated dental implants reduces operative sessions and allows faster oral rehabilitation for properly selected patients. The defects may result from trauma or resection of benign tumors or low-grade malignancies. Between August of 1999 and July of 2001, three patients underwent maxillary reconstruction with the fibula osteoseptocutaneous flap and simultaneous osseointegrated dental implants. The cause of the defect was trauma in two cases and resection of an adenoid cystic carcinoma in the other. The mean length of the fibula used for bony reconstruction was 4.7 cm. One osteotomy was performed in one case and no osteotomy was necessary in the other two. Skin islands of 8 x 2.5 cm and 16 x 3.5 cm were used for two patients. For the other patient, a double skin island was used for both nasal (6 x 4 cm) and oral (6 x 5 cm) reconstructions. Two osseointegrated implants were inserted into the fibular bone for each patient. Six months after the first-stage procedure, palatal rotation flaps or mucosa grafts were used to cover the exposed implant necks and prepare the implants for prostheses. One month after the second-stage procedure, prostheses were placed. An implant-supported prosthesis was used for one patient and implant/tissue-supported prostheses were used for the others. At a mean follow-up time of 30 months (range, 16 to 38 months), all patients were able to use the dental prosthesis for chewing (beginning 6 weeks after the final procedure) and all patients were satisfied with the cosmetic results.
腓骨骨皮瓣是三维复合上颌骨缺损重建的良好选择。该皮瓣可同时进行骨和软组织重建,并允许在一期手术或二期手术中进行骨整合牙种植。同时植入骨整合牙种植体可减少手术次数,并为合适的患者提供更快的口腔功能康复。这些缺损可能由创伤、良性肿瘤切除或低度恶性肿瘤切除引起。1999年8月至2001年7月期间,3例患者采用腓骨骨皮瓣并同时植入骨整合牙种植体进行上颌骨重建。2例缺损原因是创伤,另1例是腺样囊性癌切除。用于骨重建的腓骨平均长度为4.7 cm。1例患者进行了1次截骨,另外2例无需截骨。2例患者分别使用了8×2.5 cm和16×3.5 cm的皮岛。另1例患者,双皮岛分别用于鼻腔(6×4 cm)和口腔(6×5 cm)重建。每位患者在腓骨上植入2枚骨整合种植体。一期手术后6个月,采用腭旋转瓣或黏膜移植覆盖暴露的种植体颈部,并为安装假体做准备。二期手术后1个月,安装假体。1例患者使用种植体支持的假体,其他患者使用种植体/组织支持的假体。平均随访时间为30个月(范围16至38个月),所有患者均能够使用假牙咀嚼(最终手术后6周开始),并且所有患者对美容效果均满意。
