Can Jaw Surgery Improve Breathing?
Many patients find that orthognathic surgery has an unexpected benefit β easier breathing. Here is why.
Yes β orthognathic surgery can significantly improve breathing, particularly nasal breathing. This is one of the main functional benefits of the procedure.
How jaw surgery improves breathing:
- 1. Upper jaw surgery forward (maxillary advancement):
- Moves the floor of the nose forward
- Opens and widens the nasal passages
- Reduces nasal resistance
- Improves airflow through the nose
- 2. Lower jaw surgery forward (mandibular advancement):
- Pulls the tongue base forward
- Opens the pharyngeal airway (back of the throat)
- Reduces snoring and sleep apnea
- Improves breathing during sleep
- 3. Combined (maxillomandibular advancement):
- Both jaws moved forward for maximum airway improvement
- The most effective surgical treatment for sleep apnea
- Significantly improves both nasal and throat breathing
Who Benefits Most
- Patients who are most likely to notice breathing improvement include:
- People with a recessed midface or lower jaw
- Those who mouth-breathe due to nasal obstruction
- Patients with sleep apnea or snoring
- People who feel their airway is narrow
Clinical Guidance
One of the less talked about benefits of orthognathic surgery is improved breathing. Moving the upper jaw forward opens nasal passages, and moving the lower jaw forward opens the throat airway. Many patients report they breathe better both during the day and at night after surgery.
