An experimental neuroanatomic investigation of the innervation of the dog's tongue by the method of retrograde axonal transport of horseradish peroxidase required that chorda tympani neurectomy be performed in neonatal pups. Surgical exposure and transection of the chorda tympani proximal to its union with the lingual branch of the mandibular nerve in the past has been accomplished by radical lateral approach which is suited only for acute experimentation. This report describes a ventral surgical exposure of the extracranial portion of the chorda tympani in the dog. This surgical procedure permits long-term survival and is considered especially useful for the chronic neuroanatomic and neurophysiologic investigations on the role of the chorda tympany in taste, salivation and lingual vasodilation in the dog.
通过辣根过氧化物酶逆行轴突运输法对犬舌神经支配进行的实验性神经解剖学研究，要求在新生幼犬中进行鼓索神经切除术。过去，在鼓索与下颌神经舌支汇合近端进行手术暴露和横断，是通过根治性外侧入路完成的，该入路仅适用于急性实验。本报告描述了犬鼓索颅外部分的腹侧手术暴露。该手术方法可使动物长期存活，并且被认为对关于鼓索在犬味觉、唾液分泌和舌血管舒张中的作用的慢性神经解剖学和神经生理学研究特别有用。
