Abstract

Nasal septal turbinate (NST) is a clearly visible structure located in the anterior part of nasal cavity on the nasal septum that limits laterally the nasal valve. It is often thought that the structure of NST and its function are poorly characterized and is rarely considered by rhinosurgeons during plan and make surgery. NST represents as a fusiform area of the erectile tissue, similar in structure and function to nasal turbinate. The central part of the NST contains cartilage of the nasal septum, but most of its three-dimensional volume consists of soft tissues: mucosa, erectile tissue, blood vessels and secretory glands. According to various researchers, the main function of NST is to ensure a change in the air flow towards the nasal turbinate and the osteomeatal complex and humidification the first portion of the air at the beginning of inspiration. Destruction of NST during septoplasty can lead to tissue drying and predispose to scabs and epistaxis. Preliminary treatment results suggest that NST is an important surgical target in rhinosurgery.
