The nasal valve area is the narrowest point in the nasal airway. External nasal valve (ENV) collapse during inspiration occurs if external valve area is too narrow or its lateral component is too floppy.
Twelve patients (7 males, 5 females) aged 8 to 12 years complaining of nasal obstruction due to ENV dysfunction underwent surgical intervention using alar batten graft assisted by temporary external suspensory suture.
All patients showed subjective and objective improvement of the nasal airway. The mean Nasal Obstructive Symptom Evaluation (NOSE) was 14 ± 1.71 before surgery and 7.83 ± 1.47 1 year after surgery (significant improvement, p ≤ .0001). The mean Peak Inspiratory Flow Rate was 29.92 ± 4.46 before surgery and 42.58 ± 4.93 1 year after surgery (significant improvement, P ≤ .0001).
External nasal valve collapse in children can be managed surgically by using alar batten graft. Temporary suspension suture can be helpful for supporting of the graft until complete healing occurs.
鼻瓣区是鼻气道最狭窄的部位。如果外鼻瓣区过窄或其外侧部分过于松弛，吸气时外鼻瓣（ENV）就会塌陷。
12例年龄在8至12岁之间、因ENV功能障碍而主诉鼻塞的患者，接受了使用鼻翼支撑移植物并辅以临时外部悬吊缝线的手术干预。
所有患者的鼻气道均有主观和客观改善。术前鼻阻塞症状评估（NOSE）平均为14±1.71，术后1年为7.83±1.47（显著改善, p≤.0001）。术前平均吸气峰流速为29.92±4.46，术后1年为42.58±4.93（显著改善, P≤.0001）。
儿童外鼻瓣塌陷可通过使用鼻翼支撑移植物进行手术治疗。临时悬吊缝线有助于在移植物完全愈合前对其起到支撑作用。
