The levator labii superioris alaeque nasi muscle (occasionally shortened alaeque nasi muscle) is, translated from Latin, the "lifter of both the upper lip and of the wing of the nose". The muscle is attached to the upper frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip. [ 1 ]
The results of the procedure are long-lasting, or relatively permanent due to the use of natural tissue rather than fillers and also because the injections are made to facial expression muscles and improve graft retention. Because it is a non-incisional procedure, facial autologous muscular injections are scar-less and results appear natural.
Also if the needle is placed too medially the medial pterygoid muscle can be injected, resulting in trismus. The sphenomandibular ligament may act as a barrier to the agent if the injection is given too shallow and the lingual nerve is only anesthetized. [3] This injection can rarely cause needle tract infections of the pterygomandibular space.
Muscle Action Risorius: Smirk Buccinator: Aids chewing by holding cheeks flat Levator labii superioris: Elevates upper lip Levator labii superioris alaeque nasi muscle: Snarl Levator anguli oris: Soft smile Nasalis: Flare nostrils Orbicularis oris muscle: Purse Lips Depressor septi nasi: Depresses nasal septum Procerus: Moves skin of forehead
It passes anterior-ward deep to the platysma and depressor anguli oris muscles. It provides motor innervation to muscles of the lower lip and chin: the depressor labii inferioris muscle, depressor anguli oris muscle, and mentalis muscle. [1] It communicates with the mental branch of the inferior alveolar nerve. [citation needed]
