Plast Reconstr Surg:颅面微小症的早期下颌骨牵张和骨骼成熟时正颌矫正的需要

2019-02-17 不详 网络

关于颅面微小症患者下颌发育不良的治疗存在争议,特别是下颌骨牵引成骨的作用。作者比较了对接受或未接受早期下颌骨牵张成骨术的骨骼成熟的颅面微小症患者进行正颌手术的需求。研究人员对1993年1月至2017年3月期间评估的所有颅面部微小症患者进行了回顾性研究。该研究包括患有Kaban-Pruzansky I级至III级下颌骨的患者,并且在最近的随访时至少14岁。结果,38名受试者符合纳入标准:17名接受下

关于颅面微小症患者下颌发育不良的治疗存在争议,特别是下颌骨牵引成骨的作用。作者比较了对接受或未接受早期下颌骨牵张成骨术的骨骼成熟的颅面微小症患者进行正颌手术的需求。

研究人员对1993年1月至2017年3月期间评估的所有颅面部微小症患者进行了回顾性研究。该研究包括患有Kaban-Pruzansky I级至III级下颌骨的患者,并且在最近的随访时至少14岁。

结果,38名受试者符合纳入标准:17名接受下颌骨牵引成骨,21名接受下颌牵张成骨(平均年龄18.95±2.82岁,分别为17.95±2.14岁; p = 0.246)。下颌畸形的程度相匹配(牵引,29.4%Kaban-Pruzansky IIb级和5.9%III级;没有牵引,23.8%IIb级和9.5%III级; p = 0.788)。在正颌手术的需要方面,牵引组和非牵引组之间没有显著差异[牵引,n = 10(58.8%);没有牵引,n = 8(38.1%); p = 0.203]。

结果似乎表明,接受早期下颌骨牵张成骨术的颅面微小症患者与未接受早期下颌骨牵张成骨术的颅面微小受试者的正颌骨手术率在正颌骨成熟率方面无明显差异。受到干扰的受试者可能仍然最终需要正颌手术来矫正面部不对称。需要进一步的研究来确定牵引的最佳时机和技术,牵引期间和之后正畸管理的重要性,以及改善面部对称性的早期心理社会益处。
