自1986年至1991年对38例梅尼埃病患者进行了内淋巴囊(ES)手术,术中记录ES的位置和大小。将ES的位置分为三型:Ⅰ型ES位于沿外半规管的轴线延长线上;Ⅲ型ES位于后半规管下方,接近颈静脉球;Ⅱ型ES位于Ⅰ型和Ⅲ型之间。将ES的大小分为三型:大型长>6mm,宽>4mm;中型长3～6mm,宽2～4mm;小型长<3mm,宽<2mm。术中用3mm长的钩针测量ES的大小。术前全部病人行高分辨CT颞骨横轴位扫描,测量后半规管与岩骨后面(P-P)之间的距离。以上发现用于研究ES位置与p-P之间距离和
Thirty-eight Meniere’s disease patients underwent endolymphatic sac (ES) surgery from 1986 to 1991, recording the location and size of ES. The location of ES was divided into three types: Type I ES was located along the extension of the axis of the semicircular canal; Type III ES was located below the posterior semicircular canal close to the jugular bulb; Type II ES was located between type I and III. The ES size is divided into three types: large length> 6mm, width> 4mm; medium length 3 ~ 6mm, width 2 ~ 4mm; small length <3mm, width <2mm. Intraoperative use of 3mm long crochet ES size measurement. All patients underwent preoperative high resolution CT axial temporal scanning of the temporal bone to measure the distance between the posterior semicircular canal and the posterior petrosal bone (P-P). The above findings were used to study the distance between ES positions and p-P
