The pneumatic otoscope is indispensable in evaluating pressure within the middle ear of infants and children by measuring the tympanic membrane mobility. If the eardrum moves normally in response to positive and negative pressure, then a significant ear effusion, suppurative or nonsuppurative, is highly unlikely. Tympanic membrane color, luster, translucence, and light reflex should therefore be correlated with mobility before any decisions regarding therapy are made. In addition, the pneumatic otoscope with a veterinary otic speculum appears to be a simple and safe way to evaluate the vagina and rectum of infants and young children.
通过测量鼓膜活动度来评估婴幼儿中耳内压力时，气耳镜是必不可少的工具。如果鼓膜在正负压力作用下能正常移动，那么出现大量耳积液（化脓性或非化脓性）的可能性极小。因此，在做出任何治疗决策之前，应将鼓膜的颜色、光泽、透明度和光反射与活动度联系起来。此外，带有兽用耳镜的气耳镜似乎是评估婴幼儿阴道和直肠的一种简单且安全的方法。
