Abstract
Nasal airway patency plays an important role in the process of craniofacial growth and development.In recent years,a growing body of research has confirmed that structural abnormalities of the nasal cavity not only lead to respiratory dysfunction but may also further affect normal craniofacial skeletal development by altering airway dynamics and breathing patterns.Among these factors,inferior turbinate volume and nasal septal deviation,as key anatomical factors affecting nasal airway patency,have garnered increasing attention.An increase in inferior turbinate volume significantly reduces the effective space for nasal ventilation,elevates nasal resistance,induces persistent nasal obstruction,and forces individuals to adopt a long-term mouth-breathing pattern.Nasal septal deviation,through the dual mechanisms of physical obstruction and airflow turbulence,disrupts normal nasal ventilation and,in severe cases,may lead to compensatory hypertrophy of the contralateral inferior turbinate,forming a vicious cycle.Long-term mouth breathing disrupts the perioral muscular balance,leading to a lowered tongue position,restricted transverse development of the maxilla,high-arched palate,and a steeper mandibular plane,among other craniofacial morphological abnormalities.Furthermore,nasal septal deviation can alter the direction of mechanical tensile forces generated during cartilage growth,interfering with the normal development of the maxilla and palate.In summary,inferior turbinate hypertrophy and nasal septal deviation are not only common anatomical causes of nasal airway obstruction but may also exert profound effects on normal craniofacial growth and development in adolescents by inducing mouth breathing,disrupting muscular functional balance,and altering mechanical force transmission.This article systematically reviews the interrelationships and recent research progress regarding inferior turbinate hypertrophy,nasal septal deviation,and craniofacial development,explores their potential mechanisms of action,and aims to provide a reference for tracing the clinical etiology of malocclusion in adolescents.关键词
