Treatment of nasal valve stenosis

Nasal valve dysfunction is one of the most common causes of obstructed nasal ventilation. In most cases the cause is congenital, but iatrogenic occurrence after functional-aesthetic rhinoplasty is not infrequent. To diagnose nasal valve dysfunction, a thorough anamnesis, inspection, endoscopy, and palpation is required. If conservative therapy using rhinologic substances, as well as outer and inner stenting do not achieve the desired outcome, and the dysfunctional site can be localized, surgical procedures are indicated to improve nasal valve function. Numerous procedures and techniques are available, amongst which the most important ones shall be elucidated and discussed in the present article. These include septoplasty, septorhinoplasty, and enlargement of pyriform aperture stenosis, as well as corrections of the upper and lower lateral cartilages.
