When the jaw position relapses, the palate can narrow and the jaws can recede, resulting in a
less defined facial structure and a “weak profile.” This can affect overall appearance. The
narrowing of the palate may cause a reduced width of the smile. Additionally, the airway can
become narrower, obstructing proper airflow during breathing. As a result, breathing difficulties,
including snoring, frequent awakenings, and daytime fatigue, can occur, especially during
sleep. Over time, Obstructive Sleep Apnea (OSA) can develop.
A failed maxillomandibular advancement (MMA) surgery, which did not include a counter
clockwise rotation, left her with degenerative jaw joints. She experienced persistent jaw pain,
limited mobility, and stiffness in her jaw muscles. She heard clicking and popping sounds
whenever she moved her jaw, her teeth alignment was affected and she developed open
mouth posture. It became difficult for her to eat and speak properly and she was concerned about her changing appearance.
