[External nasal valve. Method of reconstruction with its dysfunction].

The aim of this work is to improve the reconstruction techniques the external nasal valve, with its dysfunction caused by vertically located lateral legs of the lower lateral cartilage. There is shown a brief analysis of the anatomy of the external and internal nasal valve, methods of reconstruction with its dysfunction and surgical correction of this. The method of reconstruction of the external nasal valve is proposed, where we have used the isolation and removal of the vertically extending lateral legs lower lateral cartilage and expansion of the valve zone by an auto / allogeneic cartilaginous graft.
