Material and method
This study included cephalometric radiographs of 45 male and 45 female subjects. All subjects were aged 13 years to 15 years. The subjects selected for this study were expected:
- 1.
To have undergone no previous orthodontic treatment,
- 2.
To breathe comfortably through the nose,
- 3.
Not to have any deglutition disorder or visual or hearing disorder,
- 4.
To have normal vertical occlusal relationships,
- 5.
Not to have any wound, burn, and scar tissue in the neck region.
Natural head position was determined by the
Discussion
Normal respiration denotes that nasal and pharyngeal structures are being used sufficiently.20 So that a person can breathe normally, it is necessary that not only there exist no nasal passage disease but also there exist no problem impeding the normal respiration, such as enlarged adenoid tissue and tonsil hypertrophy in the nasopharynx and oropharynx, respectively. A normal nasal airway is dependent on sufficient anatomical dimensions of the airway.36 In addition, the size of nasopharynx is
