Abstract： 目的总结髁颈及髁颈下骨折解剖复位、坚强内固定术后影响咬合关系的非骨源性因素.方法分析23例髁颈及髁颈下骨折经解剖复位、小型接骨板坚强内固定术后出现咬合紊乱的原因,并提出相应的处理措施.结果 23例术后咬合紊乱者均经曲面断层片及瓦氏位片复查,未发现小型接骨板变形、断裂以及骨折片再移位,但伴其他并发症(一过性面瘫2例;一过性下颌缘支损伤3例;感染2例;关节区疼痛2例;关节弹响及杂音1例). 结论髁颈及髁颈下骨折虽经解剖复位、小型接骨板坚强内固定,且术后并无导致咬合紊乱的骨源性因素,仍有发生咬合紊乱的可能性.其原因为肌源性和关节源性.这时,不需再次手术复位,只需颌间弹性牵引及功能锻炼,个别情况下调治疗即可恢复正常咬合关系.
