作者分析各种原因引起的面瘫病人630例,发现外周性面瘫成人比儿童高出7～8倍,这主要与小儿颞骨内面神经管解剖构造的特点有关。作者解剖34块颞骨,发现面神经垂直段,在成人面神经干占管面积的40%左右,儿童1～3岁时面神经干占管面积的25%,4～7岁占30%。随着年龄增大,面神经干的直径增粗,面神经管也越接近成人。由此似可解释儿童面瘫发病率低的原因。另外,成人慢性中耳炎和胆脂瘤的并发症较多,发生耳源性面瘫者占5.5%。而在儿童面瘫多由急性化脓性中耳炎引起,胆脂瘤少见,93例中只1例手术证实为胆脂瘤。作者观察了1～4岁的儿童面瘫64例,原因
The author analyzed 630 patients with facial paralysis caused by various reasons and found that peripheral facial paralysis in adults than children 7 to 8 times higher, which is mainly related to the characteristics of the anatomical structure of the pediatric internal temporal neural tube. The author dissected 34 temporal bones and found that the facial nerve vertical segment accounted for about 40% of adult facial nerve stemming area. Children aged 1 to 3 accounted for 25% of facial nerve trunk area, 4 to 7 years of age accounted for 30%. With age, facial nerve stem diameter increased thick, facial nerve tube closer to the adult. This may seem to explain the reasons for the low incidence of facial paralysis in children. In addition, there are more complications of chronic otitis media and cholesteatoma in adults, with otogenic facial paralysis accounting for 5.5%. In children with facial paralysis and more caused by acute suppurative otitis media, cholesteatoma rare, only 93 cases of surgery confirmed as cholesteatoma. The authors observed 1 to 4 years old children with facial paralysis in 64 cases, the reason
