Limited maxillary defects are commonly grafted with bone blocks harvested from the symphysis or the ramus; harvesting a second surgical site in the mandible increases both operative time and patient's postoperative morbidity. To overcome these disadvantages, the zygomatic buttress (ZB) was suggested as an alternative maxillary source of autogenous bone. This intraoral donor site has a natural convex shape and can be accessed along with the recipient site through the same flap design. We report a case series describing this uncommon technique of bone harvesting from the zygomatic buttress to reconstruct limited alveolar defects in the maxilla.
局限性上颌骨缺损通常采用取自下颌骨联合或下颌支的骨块进行移植;在下颌骨开辟第二个手术部位会增加手术时间和患者术后发病率。为克服这些缺点,有人提出将颧支柱(ZB)作为上颌骨自体骨的替代供区。这个口内供区呈自然凸形,并且可以通过相同的皮瓣设计与受区同时进行手术操作。我们报告了一个病例系列,描述了这种从颧支柱获取骨块以重建上颌骨局限性牙槽骨缺损的罕见技术。
