The fibula free flap (FFF) is considered a gold standard for maxillary reconstructions, and in the last few decades, this flap has been widely used for mandibular defects, with a range of modifications, which have allowed the improvement and greater success. The reconstructions of the maxilla and midface are less reported than mandibular reconstructions, despite the remarkable evolution over the years. In the reconstruction of type IIIa maxillary defects using FFF, some authors report that it may not provide enough height to support the orbit in class 3 and 4 defects. Others also encountered several difficulties, mainly in modeling fibular bone (FB) for the zygomatic-maxilla complex reconstruction and orbital floor, due to the difficulty in rotating the soft tissues, pedicle, orientation of the (FB) segments.
To show this new technique presents another option for maxillary reconstruction with a FFF in type IIIa defects.
After harvesting FFF in the standard fashion, differentiated osteotomies, modeling, and arrangement of the fibular bone segments are performed.
This new technique presented has the advantage of requiring only one flap, promoting the resolution of the technical difficulties previously reported.
游离腓骨瓣(FFF)被认为是上颌骨重建的金标准,在过去几十年中,该瓣已被广泛用于下颌骨缺损,并进行了一系列改良,从而实现了改进并取得了更大的成功。尽管多年来有了显著发展,但上颌骨和中面部的重建报道少于下颌骨重建。在使用游离腓骨瓣重建IIIa型上颌骨缺损时,一些作者报告称,在3级和4级缺损中,它可能无法提供足够的高度来支撑眼眶。其他人也遇到了一些困难,主要是在为颧上颌复合体重建和眶底塑形腓骨时,由于软组织、蒂的旋转以及腓骨段的定向存在困难。
展示这项新技术为使用游离腓骨瓣重建IIIa型缺损的上颌骨提供了另一种选择。
以标准方式切取游离腓骨瓣后,对腓骨段进行不同的截骨、塑形和排列。
所呈现的这项新技术的优点是仅需一个瓣,解决了先前报道的技术难题。
