Patients with hypoplasia of the midface normally present a flattening of their facial profile due to insufficient development of the nose and maxilla. Treatment aimed to restore function and an aesthetic appearance calls for a Le Fort III osteotomy and the advancement of the midfacial segment either through distraction or interposition of autogenous bone blocks. However, drawbacks in using autogenous bone suggest that use of alternative graft material may be advisable. The present report describes a Le Fort III advancement using two enzyme-treated equine cancellous bone blocks to correct syndromic midfacial hypoplasia in a 22-year-old patient. A 12-mm surgical advancement was achieved, improving the patient's facial profile. At the 28-month follow-up, the midface advanced position was stable. Equine bone blocks could be a valid alternative to autogenous bone in Le Fort III midface advancement.
面中部发育不全的患者通常由于鼻子和上颌骨发育不足而呈现面部轮廓扁平。旨在恢复功能和美观外观的治疗需要进行Le Fort III截骨术，并通过牵引或自体骨块植入来推进面中部节段。然而，使用自体骨的缺点表明，使用替代移植材料可能是可取的。本报告描述了使用两块经酶处理的马松质骨块进行Le Fort III推进术，以矫正一名22岁患者的综合征性面中部发育不全。实现了12毫米的手术推进，改善了患者的面部轮廓。在28个月的随访中，面中部的推进位置稳定。在Le Fort III面中部推进术中，马骨块可能是自体骨的有效替代物。
