The superior labial artery is a small blood vessel located in the upper lip of the face. It is a branch of the facial artery, which is one of the major arteries in the head and neck region. The superior labial artery supplies blood to the upper lip, the skin of the upper lip, and the mucous membranes of the mouth.
The superior labial artery begins at the angle of the mouth and travels upward along the border of the upper lip. It then branches off into smaller arteries that provide blood to the various tissues of the upper lip and mouth. The superior labial artery is an important blood vessel in the facial region as it helps to maintain the proper functioning of the tissues in the upper lip and mouth.
In addition to its role in supplying blood to the upper lip and mouth, the superior labial artery also plays a role in the development of the face during fetal development. During fetal development, the superior labial artery helps to form the upper lip and the surrounding facial structures.
Problems with the superior labial artery can lead to various issues in the upper lip and mouth. For example, if the artery becomes blocked or damaged, it can lead to tissue death and potentially even facial deformities. It is important to take care of the health of the superior labial artery to prevent these issues from occurring.
Overall, the superior labial artery is a small but important blood vessel in the face that plays a crucial role in the proper functioning of the upper lip and mouth. It is important to maintain the health of the superior labial artery to ensure that these tissues receive an adequate supply of blood.
Superior Labial Artery
The bony vault is the immobile portion of the nose. Speech is affected by nasal anatomy and pathologic conditions. The Abbe flap is a full-thickness composite flap, involving the transfer of the skin, muscle, and mucosa of the central part of the lower lip to the upper lip. A forehead flap supplies external skin. Fortunately, the deeper septum almost always remains intact within the pyriform aperture. The flaps are designed with a height equal to the defect and a width approximately half that of the defect.
Both the internal and external carotid artery systems supply blood to the nose. The anterior ethmoid, greater palatine, sphenopalatine, and superior labial arteries all form a plexus of vessels in the anteroinferior nasal septum. Lymph node metastases related to lip cancers occur in fewer than 10% of patients with cancer of the lower lip and up to 20% of patients with cancer of the upper lip and commissure. Lower lip cancers, therefore, are at higher risk for contralateral metastasis. Ipsilateral septal mucoperichondrial flaps, which are typically perfused by the ipsilateral superior labial artery, may also be used to restore lining defects of the vestibule and sidewall.
The plexus is principally supplied by branches and anastomoses of the sphenopalatine, superior labial, and anterior ethmoidal arteries and is the most common site of anterior epistaxis. An arterial arch with the diameter of 1. However, more inferiorly, it will not reach around to the alar bases. This positions a vertical sheet of bone and cartilage which can support the dorsum of the nose. In such circumstances, a bipedicle flap of residual vestibular skin can be incised in the area of the intercartilaginous line and advanced inferiorly to the desired alar rim level. The nasal blood supply can be considered to have three main sources with multiple anastomoses: the sphenopalatine considered the primary source , the superior labial, and the ethmoidal arteries. Sensory information is transported by nerves that penetrate the cribriform plate and traverse cranial nerve I the olfactory nerve to the brain.
Their viability is suspect and they do not reliably nourish primary bone cartilage grafts. Exposed spicules of bone or cartilage are removed. The septal composite flap does not supply enough mucosa to line the entire vestibule and ala. Second-stage division of the pedicle and final inset take place 14 days later Fig. This procedure also may reduce the oral aperture Fig. This lines the upper and midvault and permits simultaneous placement of primary subunit cartilage grafts.
The cartilaginous vault is supported by the upper lateral cartilages and the cartilaginous nasal septum. The OB and lateral olfactory tract receive their blood supply from a small artery that originates from the lateral surface of the anterior cerebral artery segment A2 , or from the medial fronto-basal artery. The anterior and posterior ethmoidal arteries usually exit the orbit 24 mm and 36 mm posterior to the lacrimal crest, respectively, leaving the optic nerve only 6 mm behind the posterior ethmoidal arteries. Then the mucosa of the right and left sides of the septum is reflected laterally and sutured to the lateral border of the defect. The foramen is located on the posterior aspect of the lateral nasal wall posterior to the middle turbinate.
The roof and lateral wall of the internal nasal cavity are supplied by the anterior and posterior ethmoidal arteries, sphenopalatine artery, and greater palatine artery. The labial arteries are branches from the facial artery. It emerges onto the face from the mandibular canal with the mental nerve at the mental foramen, and supplies muscles and skin in the chin region. Many believe nasal edema may be less from a closed rhinoplasty, although arguments can be made that there are adequate channels of lymphatic and venous drainage for open or closed rhinoplasty. The perioral incisions create bilateral skin and muscle flaps for rotation and advancement. The PATHWAY or location changes regularly, but it is said that the vessel is at least always in a reliable PLANE of depth.
They are usually asymptomatic and uncomplicated, however treatment can be administered to improve cosmesis and occasionally to prevent bleeding. What is the palatine artery? Graft exposure leads to infection, extrusion, scarring and retraction. Frederick J Menick MD, in Nasal Reconstruction, 2009 Central full-thickness defects of the upper middle and lower nose The high, converging medial and lateral walls of the upper and middle vaults permit the repair of modest lining defects of the superior nose by simple side-to-side approximation. Asterisk: Third ventricle and anterior commissure in the depth. It provides thin, supple, vascularized lining and central support to the nasal vestibules, the middle and upper vaults. However, the vascularity of the septal composite flap is profuse.
In the first stage, an FTSG is inset on the undersurface of the frontalis muscle for future lining and a cartilage graft is placed between the skin and frontalis for future structural support of the nostril margin. This anatomical study from Cotofino et al suggests the superior labial artery can either be deep to the orbicularis orismuscle, in the Orbicularis Oris muscle or superior to the OO muscle. Fortunately for surgeons, the septum is perfused by the septal branch of the superior labial artery, which permits elevation and lateral transfer of the septal mucous membrane on a 1. What makes up Kiesselbach plexus? A subtotal nasal amputation was required to treat squamous cell carcinoma of the anterior septum Figure 17-16. Mitral cells dendrites Mi build synaptic contacts arrows with ORN axons and tyrosine hydroxylase-positive periglomerular interneurons electron-dense deposits.
It supplies the anterior portion of the septum and medial wall of the nasal vestibule through the septal branch. The external carotid artery contributes most of the arterial supply through the internal maxillary sphenopalatine and greater palatine branches and facial arteries superior labial branch. They are preserved in the 1. The reflected dorsal mucosa can be incised and subdivided into a second transposition flap which can be reflected towards the tip. Semicircular incisions are performed from the edge of the skin defect toward the nasal ala bilaterally. This is a sensate axial musculomucocutaneous flap based upon the superior and inferior labial arteries. If the nasal bones are absent, it is difficult to stabilize a dorsal support framework.
Not according to this paper. This is removed with a knife or rongeur. But the depth is always the same. These grafts are designed to recreate a support framework wherever it is missing and will be unique for each case. Why do the inside of my lips feel wrinkly? The outline and dimensions of the septal flap are marked with ink. Cleaning of air is accomplished through the nasal hairs vibrissae and the mucosal surface.
