听神经瘤的手术入路在本世纪初即有两种:一是由神经外科医生提出的后颅窝枕下入路,此手术入路于1907年由Charles Ballance首先报导成功治愈一例听神经瘤,以后历经神经外科医生如Cushing、Dandy等加以完善,已成为较成熟的手术方法而被广泛接受。近年来由于显微手术应用于神经外科,对保留重要的神经结构如面神经和听神经功能方面也取得很大的成绩(参见本刊1977年第3期116页及 There are two kinds of surgical approaches for acoustic neuromas at the beginning of this century: First, the posterior fossa suboccipital approach proposed by a neurosurgeon. This surgical approach was first reported by Charles Ballance in 1907 to successfully cure an acoustic neuroma. After being perfected by neurosurgeons such as Cushing and Dandy, it has become a more mature surgical method and has been widely accepted. In recent years, as microsurgery has been used in neurosurgery, great achievements have also been made in the preservation of important neural structures such as facial nerve and auditory nerve function (see Journal of the 3rd issue, 1977, p. 116).
