小型钛接骨板坚固内固定治疗面中份骨折

Internal fixation with mini-titanium plate for midface fractures

３４例面中份骨折用小型钛接骨板坚固内固定治疗。采用头皮冠状切口和辅助切口，可充分显露颧骨、颧弓、眶底及上颌骨的骨折，有利于骨折片的精确复位和固定。小钛板坚固内固定为骨折固定提供了可靠的三维稳定。颧额缝和颧颌缝的固定是获得足够稳定的关键。在颧额缝上方至少需要两颗固定螺钉。

Thirty four patients with midface bone fractures were fixed by rigid inernal fixation (RIF) with mini-titanium plate. An optimum exposure is provided for the fracture sites of zygomatic, zygomatic arch, orbital floor and maxilla with the coronal iscision and adjuvant incisions. The approach was of benefit to accurate anatomic reduction and fixation of the fracture segments. RIF with mini-titanium plate provided three-dimensional stability. The fixation of zygomaticfrontal crevice and zygomatic maxillary crevice were the key for obtaining sufficient stability, and at least two fixation screws were required above zygomaticfrontal crevice.
