A total maxillectomy defect, if left unreconstructed or if poorly reconstructed, can lead to enophthalmos, orbital dystopia, feeding and speech problems, and loss of midfacial projection and vertical facial height. When the eye is preserved, despite resection of the supporting infraorbital bone during maxillectomy, bone reconstruction needs to be considered, using a vascularized bone flap. The authors have used the free fibula flap to simultaneously provide orbital support and restore midfacial projection in three patients, following total maxillectomy without orbital exenteration. For large maxillectomy defects with insufficient bony support, a free fibula flap should be considered as a reconstructive method, to adequately restore contour and the necessary structural support, and to provide optimal aesthetic and functional results.
全上颌骨切除术后的缺损,如果不进行重建或重建不佳,可导致眼球内陷、眼眶移位、进食和言语问题,以及面中部突出度和面垂直高度丧失。当保留眼球时,尽管在全上颌骨切除术中切除了支持性的眶下骨,但仍需要考虑使用带血管蒂骨瓣进行骨重建。作者使用游离腓骨瓣为3例全上颌骨切除且未行眶内容物剜出术的患者同时提供眼眶支持并恢复面中部突出度。对于骨支持不足的大型上颌骨切除术后缺损,应考虑将游离腓骨瓣作为一种重建方法,以充分恢复外形和必要的结构支持,并提供最佳的美学和功能效果。
