Nasal patency in mouth breathing children

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...

Mouth breathing in children with learning disorders.

UNLABELLED Given the importance of studying the causes of learning disorders, we designed this case-control study to assess the nasal cavity volume, pharyngeal and palatine tonsils in children with and without learning disabilities. METHOD A total of forty-eight children were enrolled in the study: twenty-four coming from the Center for Evaluation and Early Stimulation (CADEP), in which the c...

Nasal resistance, skeletal classification, and mouth breathing in orthodontic patients.

Three-dimensional assessment of pharyngeal airway in nasal- and mouth-breathing children.

OBJECTIVES The aim of this study was to assess the pharyngeal airway space (PAS) in nasal and mouth-breathing children using cone beam computed tomography (CBCT). METHODS Volume, area, minimum axial area and linear measurements (PAS-NL, PAS-UP, PAS-OccL, PAS-UT, PAS-Bgo, PAS-ML, PAS-TP) of the pharyngeal airway of 50 children (mean age 9.16 years) were obtained from the CBCT images. The means...

Electrical Activity of the Anterior Temporal and Masseter Muscles in Mouth and Nasal Breathing Children Summary

Mout h breathing has been associated with severe impact on the development of the stomatognathic system. Aim: This paper aims to analyze the electromyographical findings and patterns of electrical activity of the anterior temporal and masseter muscles in mouth and nasal breathing children. Materials And Method: The patients were divided into two groups: mouth breathers (n=17) and nasal breather...
