面瘫患者能否在发病之早期判断其可能难于自行恢复,对此已有广泛研究和改进了的电诊断技术,通过若干方法和试验在早期判明面瘫的预后,以求对预后不良者及早给予有效的治疗,然而迄今尚无一种单一的试验能在面瘫早期作出100%精确的预后。虽然用来侦查神经的远端有无神经纤维的脂肪变性的电诊断试验,已证明是一种较好的预后指标,其中神经 Patients with facial paralysis can judge early in the onset may be difficult to self-recovery, which has been extensively studied and improved diagnostic techniques, through several methods and tests in the early identification of facial paralysis prognosis, in order to poor prognosis early effective However, to date, no single trial has resulted in a 100% accurate prognosis in the early stages of facial paralysis. Although the electrical diagnostic test to detect the presence or absence of nerve fibers on the distal end of the nerve has proved to be a good prognostic indicator,
