Jaw Structure
The structure of the upper and lower jaw also plays a role in the progression of sleep apnea. The people having inferior upper jaw mostly suffer from sleep apnea as the nasal airway is compromised. The reason is that the bone present at the roof of the mouth and the bone which is present at the base of the nasal pathway is the same so when the roof of the mouth is restrained the nasal airway will also be restricted causing the closing of the path and making the process of breathing difficult.
