Corpus: Depressor septi muscle: Unterschied zwischen den Versionen

The Musculus depressor septi nasi is a small muscle in the area of the nose. It is part of the mimic musculature.

The depressor septi nasi muscle has its origin in the incisive fossa of the maxillary bone (maxilla). Its fibres run medially and cranially. There they radiate into the cartilage of the nasal septum (cartilago septi nasi) and the nasal wing (cartilago alaris nasi), where they find their insertion.

The depressor septi nasi muscle is innervated by the rami buccales of the VII cranial nerve (facial nerve).

The depressor septi nasi muscle pulls the tip of the nose and parts of the nostril downwards.

Botulinum toxin treatments targeting the depressor septi nasi muscle as well as dissections of the muscle as part of rhinoplasty are widely used to raise the tip of the nose.^[1][2]
