摘要
目的 测量大前庭水管综合征(large vestibular aqueduct syndrome, LVAS)患者耳蜗的径线,探讨其在人工耳蜗植入术前评估的意义。方法 收集符合入选标准的40例大前庭水管综合征患者(LVAS组)和40例内耳结构正常的先天性感音神经性聋患者(对照组)的颞骨高分辨率CT资料,通过多平面重组,测量耳蜗各径线数据,包括长径A、宽径B、高度H以及耳蜗蜗管长度L,比较两组结果。结果 两组组内男女之间耳蜗各径线存在差异,女性各径线均小于男性(P<0.05)。LVAS患者的耳蜗长径A为8.88±0.43 mm、宽径B为6.57±0.43 mm、高度H为2.99±0.25 mm、蜗管长度L为33.94±1.99 mm;对照组分别为长径A 9.27±0.52 mm、宽径B 6.99±0.41 mm、高度H 3.04±0.34 mm、耳蜗蜗管长度L 35.79±2.18 mm。LVAS组长径A、宽径B、蜗管长度L较对照组小,差异有统计学意义(P<0.05),两组间耳蜗高度H差异无统计学意义(P>0.05)。结论 大前庭水管综合征患者耳蜗长径A、宽径B及蜗管长度L比内耳结构正常的先天性感音神经性聋患者小,CI术前测量耳蜗各径线,可以为植入电极的个性化选择及手术提供参考。
