Corpus: Depressor septi muscle: Unterschied zwischen den Versionen

The depressor septi nasi muscle is a small muscle located in the nasal area, and it is part of the facial expression muscles (mimic musculature).

The depressor septi nasi muscle originates in the incisive fossa of the maxillary bone. The muscle fibers run medially and cranially, inserting into the cartilage of the nasal septum and the cartilage of the nasal wing.

The depressor septi nasi muscle is innervated by the buccal branches (rami buccales) of the facial nerve, which is the seventh cranial nerve (CN VII).

The primary function of the depressor septi nasi muscle is to pull the tip of the nose and parts of the nostril downward.

In cosmetic procedures, such as rhinoplasty, the depressor septi nasi muscle is often targeted. Botulinum toxin injections can be used to relax this muscle, resulting in the elevation of the nasal tip. Additionally, surgical dissection of this muscle is sometimes performed to achieve similar aesthetic effects.^[1][2]
