Facial Muscle Firming Treatment - Superior Maxillary Region

Levator Labii Superioris Facial Muscles

The pair of muscles known as the Levator labii superioris are thin and quadrilateral in shape.

They originate from the lower margin of the orbit where some fibres attached to the superior maxillae, others to the malar bones.

They are inserted into the muscular substance of the upper lip. Their action is to raise and extend the upper lip.

Levator Anguli Oris Facial Muscles

The Levator anguli oris muscles each originate in the canine fossa immediately below the infraorbital foramen.

The fibres pass down and outward to be inserted into the angle of the mouth intermingling with those of the Zygomaticus, the Depressor anguli oris, and the Orbicularis.

Their action is to elevate the angle of the mouth.

Zygomaticus Major Facial Muscles

The Zygomaticus major muscles are slender bundles which originate from the malar bones, in front of the zygomatic suture.

Their fibres extend obliquely downward and inward to be inserted in the angles of the mouth where they blend with those of the Levator anguli oris, the Orbicularis oris, and the Depressor anguli oris.

Their action is to draw the angles of the mouth up and back.

Zygomaticus Minor Facial Muscles

The Zygomaticus minor muscles originate from the malar bone immediately behind the malar suture and extend downward and inward to insert into the Orbicularis oris.

Their action is to draw the upper lip up and out; form nasolabial furrow.
