【摘要】 目的：探求进一步提高镫骨提高术疗效的途径。方法：对15具新鲜尸头的砧、镫骨及前庭窗等作解剖学研究，对有关本手术的数据进行观测。结果（以x±s计）：砧镫间夹角为91．90±4．49（83～100）°、豆状突长度为0．46±0．04（0．40～0．56）mm、镫骨头颈高度为0．61±0．04（0．56～0．68）mm、足板下缘厚度为0．30±0．04（0．26～0．40）mm，以及前庭窗龛上下壁倾角为35．28±3．86（31～39）°、16．75±1．89（14～18）°。据此，对经现行的两种术式治疗的病例，分别作近期与远期疗效比较，差异均无显著性意义。结论：两种术式均基本符合生理解剖学结构原理，但根据解剖结构有时也需选择术式。此外常规应用生物胶粘合剂或滴入血液以稳固砧镫联结，是谋求提高疗效的一项可行办法。更多还原

【Abstract】 Objective: For the purpose of improving patient’s hearing in stapes elevation surgery. Method:The anatomical features relating to this operation were observed and measured in 30 ears of fresh cadavers,whichincluded the length of lenticular process,the highness of stapes head and neck,the thickness of lower border offootplate, the angle of incudostapecial joint and the gradients of upper and lower wall of vestibular niche. The re-lation between two types of the present operation and the investigation were discussed. Result:The two types ofpresent operations were in accord with the physiologicoanatomical features of the stapes and incus. Conclusion:Inorder to improve the patient’s hearing, making use of biobinder for strengthening the incudostapedial connexionas a routine is suggested.更多还原
