前言鼻成形术(Rhinoplasty)的适应症取决于鼻形态结构和功能的检查。后鼻孔闭锁在文献中常有报导,家族性后鼻孔闭锁的报导却很少见。病因: 主要病因有以下几种学说:在原始口鼻腔间隔以Hochstetter鼻颊膜,此膜以后衍生嗅板,并形成原始鼻腔陷凹。正常情况下,此膜于胚胎第7周破裂,形成原始后鼻孔,位于前颌骨(Premaxilla)之后。此膜如不破裂,便形成后鼻孔闭锁,其位置比较靠前,因此作者并不完全同意此学说。

Preface Rhinoplasty’s indications depend on the examination of nasal morphology and function. Posterior nostril atresia is often reported in the literature, and familial posterior nosocomial atresia reports are rare. Etiology: The main etiology has the following theories: in the original mouth and nose interval to Hochstetter nasal buccal membrane, this film later derived olfactory plate, and the formation of the original nasal cavity depression. Normally, this membrane ruptured at 7th week of embryo to form the posterior nostril behind the Premaxilla. If the film is not ruptured, it will form the posterior nostril atresia, the location of the front, so the author does not completely agree with this doctrine.
