Discussion on Mouth-Breathing and Nasal Obstruction

Nasal Obstruction and Palate-Tongue Position on Sleep-Disordered Breathing

OBJECTIVES We wanted to evaluate whether the presence of nasal obstruction makes a change on the association between the modified Mallampati score and the severity of sleep-disordered breathing (SDB) and the sleep quality. METHODS Polysomnography (PSG), the modified Mallampati score (MMS), the body-mass index, and a questionnaire about nasal obstruction were acquired from 275 suspected SDB pa...

The effect of mouth breathing versus nasal breathing on dentofacial and craniofacial development in orthodontic patients.

OBJECTIVES/HYPOTHESIS To determine the effect of mouth breathing during childhood on craniofacial and dentofacial development compared to nasal breathing in malocclusion patients treated in the orthodontic clinic. STUDY DESIGN Retrospective study in a tertiary medical center. METHODS Clinical variables and cephalometric parameters of 116 pediatric patients who had undergone orthodontic trea...

Electromyographic muscle EMG activity in mouth and nasal breathing children.

Mouth breathing may cause changes in muscle activity, because an upper airway obstruction leads may cause a person to extend his/her head forward, demanding a higher inspiratory effort on the accessory muscles (sternocleidomastoids). This purpose of this study is to compare, using electromyography (EMG), the activity pattern the sternocleidomastoid and upper trapezius muscles in mouth breathing...
