目的：探索一种膜迷路积水的客观判断方法。方法：采用计算机图像分析技术对豚鼠内耳组织切片做了相关数据的测试，并将正常组与积水模型组做比较。结果：正常组豚鼠耳蜗的中阶面积底回为１２４４３．０±４０７．２，顶回７６５２．２±１５５９．２，前庭膜长度底回１４９．６±１４．７，顶回１２１．３±２２．０。积水组中阶面积底回２３３６６．８±５０４５．８，顶回１０２０２．０±２９２７．９，前庭膜长度底回２２８．８±６２．７，顶回１２９．４±２１．９。统计分析，积水组中阶面积蜗管各部（Ｃ１－Ｃ８）与正常组均有显著差异。结论：计算机图像分析法测定中阶面积及前庭膜长度，准确可靠，应用于积水耳蜗的测定较传统法（光镜下主观判断）更为科学、可信。
Objective: To explore a method of objective judgments of labyrinth of membranous labyrinth. Methods: The data of the inner ear tissue of guinea pigs were tested by computer image analysis technique, and the normal group and the hydrocephalus model group were compared. Results: In the normal group, the mid-step area of the cochlea in the guinea pigs was 12443.0 ± 407.2, and the top was 7652.2 ± 1559.2. The length of the vestibular membrane was 149.6 ± 14.7 at the base and 121.3 ± 22.0. In the hydrocephalus group, the mid-step area was 23366.8 ± 5045.8 at the bottom, and 10202.0 ± 2927.9 at the top. The length of the vestibular membrane was 228.8 ± 62.7 at the end and 129.4 ± 21.9 at the top. Statistical analysis, hydrocephalus group Sciotic segment (C1-C8) were significantly different from the normal group. Conclusion: The computer image analysis method for the determination of mid-size and vestibular membrane length is accurate and reliable. It is more scientific and credible than the traditional method (subjective judgment under light microscope) for the determination of hydrocephalus.
