Редкие причины назальной обструкции

Abstract

Nasal obstruction can be influenced by numerous anatomical and physiological factors. For rhinosurgeons, it is important to know about the existence of such muscular and vascular components of the internal nasal valve (INV) region as the nasal septal swell body (NSB) and the nasal vestibular body (NVB) that – like other components of the INV – can take part in the development of the nasal obstruction. The body of the nasal septum is a glandular structure consisting of seromucous glands and venous sinusoids. It is associated with the area of the internal nasal valve and provides additional resistance to nasal airflow. The nasal vestibular body is an unstable dynamic vascular structure of the internal nasal valve, which is located on the inferolateral border of the area of the internal nasal valve, immediately in front of the head of inferior turbinate. There is currently no consensus regarding the surgery of these muscular and vascular components of the internal nasal valve for the treatment of nasal obstruction. However, the studies described in this review may indicate the effectiveness of surgical reduction of NSB and NVB. At the same time, other anatomical causes of nasal obstruction, such as hypertrophy of the inferior turbinate or deformation of the nasal septum, may interfere with the analysis of the described structures of the INV region, which may compromise the results of standard surgical interventions for nasal obstruction.
