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。
Objective: To explore ways to further improve the stapes to improve the curative effect. METHODS: Anatomical studies were performed on 15 anterior cadaver anvils, stapes and vestibular windows, and the data of the operation were observed. Results (in terms of x ± s): The angle between the anvils was 91.90 ± 4.49 (83-100) °, the length of the soya was 0.46 ± 0.04 (0.40-0.56) mm, the height of 镫 bone neck was 0.61 ± 0.04 (0.56 ~ 0.68) mm, the thickness of the lower edge of foot plate was 0.30 ± 0.04 (0.26 ~ 0.40) mm, and The inclination of the upper and lower walls of the vestibular niche was 35.28 ± 3.86 (31-39) ° and 16.75 ± 1.89 (14-18) °. Accordingly, there is no significant difference between the short-term and long-term efficacy of the current two types of surgical treatment cases. Conclusion: The two surgical procedures are basically consistent with the principles of physiological anatomy, but according to the anatomy and sometimes need to choose surgery. In addition to the conventional application of bio-adhesive or glue into the blood to stabilize the anvil joint is to seek to improve the efficacy of a feasible way.
