Breathing mode influence on craniofacial development and head posture.

Area of Science:

• Dentistry
• Orthodontics
• Pediatrics

Background:

• Abnormal breathing patterns, particularly oral breathing, are increasingly prevalent.
• These patterns can influence craniofacial development, even in individuals without distinct facial anomalies.
• Understanding these effects is crucial for early intervention and management.

Purpose of the Study:

• To compare cephalometric differences in craniofacial structures and head posture.
• To differentiate between nasal and oral breathing in children and teenagers with normal facial growth patterns.

Main Methods:

• Ninety-eight patients aged 7-16 with normal facial growth were evaluated.
• Breathing modes were determined through clinical assessment and airflow sensing.
• Participants were grouped by age (7-9 and 10-16 years) to account for growth stages.

Main Results:

• Younger oral breathers (7-9 years) had smaller nasopharyngeal dimensions.
• Older oral breathers (10-16 years) showed increased palate length and lower anterior face height.
• Adolescent oral breathers also exhibited a lower hyoid bone position relative to the mandibular plane.
• No significant differences in head posture were observed between groups.

Conclusions:

• Oral breathing, even in normal facial growth patterns, is associated with airway dimension differences in children.
• In adolescents, oral breathing correlates with specific changes in facial structures and hyoid bone position.
• These findings highlight the subtle yet significant impact of breathing patterns on craniofacial development.
