随着翼管神经切断术和面神经手术的开展,急需寻求疗效评估和定位诊断的可靠检查法。翼管神经是由岩浅大神经(副交感)及岩深神经(交感)组成的混合神经,含有支配泪腺分泌的副交感纤维,司理鼻及软腭粘膜的交感和副交感纤维,来自软腭味觉感受器的感觉纤维及司理面部血管的血管运动神经纤维,其副交感中枢在脑干内上涎核及面神经运动核周的神经元群。目前认为泪液分泌检查法中应用最广、简而易行的乃是Schirmer法和鼻泪反射法。前者系在结膜表面麻醉后,用宽5 mm、长35mm的滤纸条挂于下睑缘,记录5分钟后纸条被浸湿的长度;后者用一简单的鼻粘膜三
With the development of pterygoid nerve transection and facial nerve surgery, there is an urgent need to seek reliable methods of assessing efficacy and positioning diagnosis. The pterygoid nerve is a mixed nerve composed of superficial petrous nerves (parasympathetic) and deep petrosal nerves (sympathetic), with sympathetic and parasympathetic fibers that govern the secretion of the lacrimal gland, sympathetic and parasympathetic fibers that manage the nasal and soft palate mucosa, sensory fibers from soft palate-taste receptors And the facial nerve vascular motor nerve fibers, the parasympathetic center in the brainstem supratentorial nucleus and facial motor neurons perinuclear group. Currently considered the most widely used method of tear secretion test, simple and easy to Schirmer method and nasolacrimal reflex method. The former is the surface of the conjunctiva anesthesia, the width of 5 mm, 35mm long filter paper hanging on the lower eyelid, record 5 minutes after the length of the wet paper; the latter with a simple nasal mucosa three
