Reduction of Square Jaw
Square jaw reduction can narrow one's lower one-third of the face, particularly if it's caused by the lower jaw and the surrounding muscles. Excessive chewing or teeth grinding at night (a condition known as Bruxism) may cause the masseter muscles to enlarge or hypertrophy, causing the square jaw look. Bruxism in turn, may cause headaches and temporo-mandibular joint (TMJ) aching in some people. While lower square jaws are often considered a positive trait in men, a wide lower jaw in women can distort the natural appearance of the angle between the chin and the neck, and
cause significant facial discordance and/or masculinization of the female face. Even in certain men, the size of the lower jaw can cause facial disharmony—particularly when there is asymmetry. This square jaw appearance is further accentuated in Asians because of their smaller facial structures. Square jaw reduction can create an almond shaped face shape for ladies and a youthful sleek look for the men. Surgical and non-surgical methods are available for the treatment of square jaw.
Surgical techniques can be used to directly reduce the size of an enlarged mandible (lower jaw). Small incisions are made usually inside of the mouth, and instrumentations are used to remove the outer layer of the enlarged mandible, narrowing the jaw. Internal incisions are performed because they do not leave any visible scars. If the upper and lower jaws are not in alignment, it is likely that the teeth need to be corrected to accommodate for the new improved jaw positions and this is accomplished with orthodontics.
Another method for square jaw reduction is to treat the enlarged lower jaw muscles (masseter muscles) with jaw-reduction micro-injections. This procedure relaxes your enlarged jaw muscles so that the muscle mass slowly decreases over several months. There is no down-time and improvement is gradual. Dosage is adjusted upon an assessment of your facial muscles. Some individuals require more while others may require lesser to obtain an optimal result. Improvement is generally seen 2 – 3 weeks after treatment. Peak improvement occurs at 3 to 9 months with good results still observable at one year in many patients.
