the elevator muscle group that includes the procerus muscle and the levator labii superioris alaeque nasi muscle. the depressor muscle group which includes the alar nasalis muscle and the depressor septi nasi muscle. the compressor muscle group that includes the transverse nasalis muscle. the dilator muscle group which consists of the dilator naris muscle that expands the nostrils; it is in 2 parts: (i) the dilator nasi anterior muscle, and (ii) the dilator nasi posterior muscle.
B. Aesthetics of the nose nasal subunits and nasal segments [modify] To prepare, map, and execute the surgical correction of a nasal defect or defect, the structure of the external nose is divided into 9 aesthetic nasal subunits, and 6 aesthetic nasal sectors, which offer the plastic cosmetic surgeon with the measures for figuring out the size, degree, and topographic area of the nasal problem or deformity.
the dorsal nasal segment the lateral nasal-wall sectors the hemi-lobule segment the soft-tissue triangle sections the alar sectors the columellar sector Nose job: The Common carotid artery. Utilizing the co-ordinates of the subunits and segments to determine the topographic location of the defect on the nose, the plastic surgeon strategies, maps, and carries out a rhinoplasty treatment.
Thus, if more than 50 percent of a visual subunit is lost (harmed, defective, damaged) the cosmetic surgeon replaces the entire visual segment, usually with a local tissue graft, gathered from either the face or the head, or with a tissue graft harvested from somewhere else on the client's body. C. Go Here For the Details and veins [modify] Like the face, the human nose is well vascularized with arteries and veins, and hence supplied with plentiful blood.
The external nose is supplied with blood by the facial artery, which becomes the angular artery that courses over the superomedial element of the nose. The sellar region (sella turcica, "Turkish chair") and the dorsal area of the nose are provided with blood by branches of the internal maxillary artery (infraorbital artery) and the ophthalmic arteries that originate from the internal typical carotid artery system.
