Abstract

Influence of adenotonsillar hypertrophy on dentofacial development of children

Highlights

The airway, respiratory pattern and craniofacial formation are interrelated and the pharyngeal structures such as adenoid and tonsils play an important role in the adequate facial growth and bony development [1]
Since normal nasal breathing is frequently disrupted in these children, many attempts have been made to establish a causal relationship between dentofacial abnormalities and pharyngeal airway obstruction associated with adenotonsillar hypertrophy [3]
Regarding the measurements of the SNA and SNB, which indicate the antero-posterior position of the maxilla and mandible in relation to the cranial base, the statistical analysis showed that the maxilla and mandible were more retrognathic against cranial base in children with adenotonsillar hypertrophy than control group

Summary

Introduction

The airway, respiratory pattern and craniofacial formation are interrelated and the pharyngeal structures such as adenoid and tonsils play an important role in the adequate facial growth and bony development [1]. The upper airway obstruction during childhood may result in various dentofacial alterations depending on the magnitude, duration and time of occurrence [2]. Early diagnosis and treatment of any restriction of pharyngeal airway is imperative to normalize form and function and ensure proper orthodontic stability and craniofacial growth. Hypertrophy of the adenoid and palatine tonsils are one of the most frequent causes of upper respiratory obstruction in pediatric population. Since normal nasal breathing is frequently disrupted in these children, many attempts have been made to establish a causal relationship between dentofacial abnormalities and pharyngeal airway obstruction associated with adenotonsillar hypertrophy [3]. Investigations have produced mixed results, suggested dentofacial alterations include a constricted maxillary arch, retrognathic mandible, steep mandibular plane angle, increased anterior facial height and malocclusion [4,5]
