[The nose, an orthodontic-surgical marker]

Area of Science:

• Physiology
• Anatomy
• Embryology

Background:

• Facial mechanics research seeks a universal physiological marker.
• The nose's role in physiological function is often underestimated.

Purpose of the Study:

• To identify a universal marker for facial mechanics.
• To re-evaluate the significance of nasal function in physiology.

Main Methods:

• Literature analysis integrating embryology, anatomy, and respiratory physiology.
• Review of existing research on nasal function and facial mechanics.

Main Results:

• Nasal ventilation at rest emerges as a significant factor in facial mechanics.
• A novel perspective on the nose's physiological importance is presented.

Conclusions:

• Nasal ventilation at rest is a crucial consideration in therapeutic approaches.
• Optimizing nasal ventilation should be a primary goal in various therapies.
