尊敬的编辑部老师:您好!贵刊2017年第31卷第14期金哲如、林萍等学者发表的《水平半规管良性阵发性位置性眩晕李氏复位法实验模型研究》一文,对李氏复位法治疗水平半规管良性阵发性位置性眩晕(BPPV)的效果和作用机制提出了不同意见,该研究对颞骨医学影像学数据进行三维内耳重建并分割内耳结构,采用角度中间值内耳作为标准模型,并设计等腰直角三棱柱作为空间方位标识。通过标准空间半规管模型进行李氏复位法 Dear Editor: Hello! Your issue 2017 Vol. 31 No. 14 Jin Zheru, Lin Ping and other scholars published “horizontal semicircular canal benign paroxysmal positional dislocation Lee experimental study of the reposition method,” a text on the Lee Different views were put forward on the effect and mechanism of reduction therapy on the level of semicircular canal benign paroxysmal positional vertigo (BPPV). The study reconstructed three-dimensional inner ear muscles and segmented the inner ear anatomy of the temporal bone medical imaging data. The middle angle inner ear was used as the standard model , And design isosceles right angle prism as the spatial orientation of the logo. Li’s method of resetting is performed through the standard space semicircular canal model
