任何鼻气道的大小不仅取决于中隔分隔部和下鼻甲的宽度和轮廓，而且还取决于在通气的动态过程期间发生的压力变化下鼻侧壁的位置和稳定性。因此，任何先天性或后天的弱点，上部或下部的外侧软骨或其投资软组织可能会深刻地影响能力，以吸引足够的空气体积通过nose.Sixteen手术治疗的病人不全的外鼻阀（包括皮肤和骨骼支持的移动的鼻壁）是本文的主题。对16例“纯"外瓣膜功能不全患者的鼻测压数据显示，对于伴有前庭皮肤缺陷的患者，采用鼻中隔软骨或骨移植物或复合耳甲软骨皮肤移植物进行瓣膜重建后，总平均鼻气流增加了两倍。7例合并外瓣和间隔病变的患者术后气流改善主要来自瓣膜缺损的矫正。外鼻瓣可能是某些患者鼻气道阻塞的重要原因，其病理生理学和治疗在初次和二次鼻成形术中进行了讨论。
The size of any nasal airway depends not only on the width and contour of the septal partition and inferior turbinates but also on the position and stability of the lateral nasal wall under the pressure changes that occur during the dynamic process of ventilation. Thus any congenital or acquired weakness of the upper or lower lateral cartilages or their investing soft tissues may profoundly affect the ability to draw adequate volumes of air through the nose.Sixty-one surgical patients treated for incompetence of the external nasal valves (comprising the cutaneous and skeletal support of the mobile alar walls) are the subjects of this paper. Rhinomanometric data on 16 patients with ''pure'' external valvular incompetence showed a twofold increase in total mean nasal airflow following valvular reconstruction with septal cartilage or bone grafts or with composite conchal cartilage-skin grafts for patients with associated vestibular skin deficiencies. Seven patients with combined external valvular and septal pathology derived most of their postoperative airflow improvement from correction of the valvular defect. The external nasal valve may be a substantial cause of nasal airway obstruction in some patients; its pathophysiology and treatment are discussed in primary and secondary rhinoplasty.
