鼓气耳镜检查可判断鼓膜的活动度,鼓膜活动受限见之于浆液性中耳炎、鼓膜及中耳慢性疾患。耳镜顶端与外耳道之间务必完全密接,这样操作对幼小、爱动的儿童来说会感到不舒服。作者介绍取化验用橡胶管一段(3/8英寸),套入耳镜上段,耳镜尖端露出1/8英寸,检查时既不阻断视野,也能避免镜尖接触外耳道较敏感部分。
Drum examination otoscopy can determine the activity of the tympanic membrane, tympanic membrane activity is limited to serous otitis media, tympanic membrane and chronic diseases of the middle ear. Be sure to completely close the top of the otoscope with the external auditory meatus, this operation for young, love moving children will feel uncomfortable. The author introduces a test tube (3/8 inch) into the upper part of the otoscope. The tip of the otoscope shows 1 / 8th of an inch. The examination neither blocks the field of view nor prevents the lens tip from touching the more sensitive part of the external auditory canal.
