Two methods for sampling inner ear fluid (a mixture of endolymph and perilymph) from corpses are described and compared. Using the classical method, a part of the petrous bone is chiselled out and, subsequently, a needle, attached to a 1-ml-syringe, is inserted through the oval foramen into the region of the utriculus. The inner ear fluid can then be removed. When the method proposed by Trela (1975) is applied, thin layers of the petrous crest are chiselled out until the common crus of the superior and posterior semi-circular becomes apparent. With a needle, attached to a 1-ml-syringe, the inner ear fluid can then be collected. The experiments show Trela's method to be simpler than the classical method. Moreover, only small amounts of inner ear fluid can be obtained by the latter technique. Trela's method is recommended for further studies on this fluid, which may be of forensic interest.
本文描述并比较了两种从尸体中采集内耳液（内淋巴和外淋巴的混合物）的方法。采用经典方法时，需凿出部分颞骨岩部，随后将连接1毫升注射器的针头经椭圆孔插入椭圆囊区域，进而抽取内耳液。应用特雷拉（1975年）提出的方法时，需凿去颞嵴薄层，直至上半规管和后半规管的总脚清晰可见，然后用连接1毫升注射器的针头采集内耳液。实验表明，特雷拉的方法比经典方法更简便。此外，采用后一种技术只能获取少量内耳液。鉴于这种液体可能具有法医学研究价值，建议采用特雷拉的方法进行进一步研究。
