[Surgical procedures for the anatomical characteristics of the nasal valve. Anatomy, physiology, pathology, and pathophysiology. Possibilities for surgical treatment].

The authors consider the nasal valve as an atomic particularity of the nose and its physiology. The nasal valve is formed by the caudal edge of the lateral cartilage and the septal cartilage. Each mutation in it leads to dyspnoea. The authors sugest operative methods for treatment of nasal valve's defects.
