Whether it is from a narrow maxilla that leads to the retraction of the mandible (Scenario 1), a retruded maxilla that also leads to a retruded mandible (Scenario 2), or a large tongue; the end effect is the blockage of the airway. The patients will open up the airway by moving the head forward. This forward posturing causes muscle soreness for the head, neck, and shoulder. Tension headache usually follows. Numbness for the fingers can also happen as the stiffness spreads further down the upper back.
The reposition of the mandible forward will help open up the airway and the head will gradually move back to its neutral, balance position directly on top of the shoulder. Chiropractors regularly treat these patients without realizing the main cause of it. They blame it on the excessive use of smart phones, sitting habit, driving position, etc… As soon as the physical therapy stops, the symptoms start to come back. The only permanent solution to treat TMD/Airway Obstruction is to advance the mandible and the tongue forward and open up the airway passage.
