Reevaluation of the arterial blood supply of the auricle

The anatomical basis for auricular flaps used in multiple aesthetic and reconstructive procedures is currently based on a random distribution of the underlying arterial network. However, recent findings reveal a systematic pattern as opposed to the present concepts. Therefore, we designed this study to assess the arterial vascular pattern of the auricle in order to provide reliable data about the vascular map required for surgical interventions. Sixteen human auricles from eight body donors (five females/three males, 84.33 ± 9.0 years) were investigated using the unique ‘Spalteholz’ method. After arterial injection of silicone, a complete transparency of the tissue was achieved and the auricular arteries and branches were visible. Qualitative and quantitative evaluation of the arterial vascular pattern was performed. The superior and the inferior anterior auricular artery provided the vascular supply to the helical rim, forming an arcade, i.e. helical rim arcade. On the superior third of the helical rim another arcade was confirmed between the superior anterior auricular artery and the posterior auricular artery (PAA), i.e. the helical arcade. The perforators of the PAA were identified lying in a vertical line 1 cm posterior to the tragus, supplying the concha, inferior crus, triangular fossa, antihelix and the earlobe. The results of this study confirmed the constant presence of the helical rim arcade (Zilinsky‐Cotofana), consistent perforating branches of the PAA, and the helical arcade (Erdman), and will help and guide physicians performing auricular surgeries toward fast and simple procedures with optimal patient satisfaction.     

Anatomy of the superficial temporal artery and its branches: its importance for surgery

The temporoparietal, parieto-occipital flaps or the forehead flaps that are used in reconstructive surgery are prepared on the superficial temporal artery (STA) and its branches. For a successful surgery and a suitable flap design, adequate anatomical knowledge is needed. In our study, the red colored latex solution was injected into the external carotid artery; the STA and its branches were dissected in 27 specimens. The mean diameter of the STA at the zygomatic arch was determined as 2.73±0.51 mm. The diameters of the frontal branch were bigger than those of the parietal branch in 15 samples out of 27. The diameters of both the frontal and parietal branches were equal in four samples. The diameter of the parietal branch was bigger than that of the frontal branch in eight samples. In 20 samples out of 27 (74.07%), the bifurcation point of the STA was above the arch. In six samples (22.22%), the STA bifurcated directly over the arch. In only one sample (3.70%), bifurcation was not observed and the STA continued only as a frontal branch (absence of the parietal branch). The absence of the frontal branch was not encountered. In one sample (3.70%), double parietal branches were observed. In six samples out of 27 (22.22%), zygomatico-orbital artery was not encountered. In 21 samples (77.77%), zygomatico-orbital arteries ran towards the face, parallel to zygomatic arch and distributed in the orbicularis oculi muscle. The transverse facial artery existed in all samples. The auricular branches running to the helix and tragus were observed in all samples. The STA was 16.68±0.35 mm at the front of the tragus. Some landmarks were chosen on the head and then the STA was observed where it crossed all of these landmarks. This paper confirms the well-known variability of the superficial temporal arterial branches and their relation to the pericranial region. Knowledge concerning the arterial features of the lateral forehead region is important for the aesthetic surgeon. STA and its branches have been found to be suitable for use in microvascular anastomoses. A better understanding of the midline forehead vascularity should allow modification of reconstructive techniques and reduce postoperative complications.

The superficial temporal artery: anatomical type and clinical application to the flap of the fascia temporal superficialis

The goal of our study is to assess the anatomical type of the superficial temporal artery (STA) in the black population using the classification of Ricbourg et al.. Forty-seven fresh cadavers and three extracted and frozen heads were included in this study. The external carotid artery was isolated in the neck and injected by Rhodopas stained with Congo Red. The superficial temporal artery was dissected using a Y-shaped skin incision. The last step of the procedure was to remove the flap of the fascia superficialis temporis. The third segment of the superficial temporal artery and its terminal branches were studied. This segment courses cephalad and wraps the zygomatic arcade. It splits into two terminal branches: the temporo-frontal and the temporo-parietal ones. The most important of its collaterals, the zygomato-maleus artery, plays a crucial role for distinguishing the subtypes of STA according to the classification of Ricbourg et al.. Indeed, this branch can be subdivided into two types: --type I: the zygomato-malar artery arises from the trunk of the STA; it courses perpendicular and with a slightly ascending direction; this type accounts for 93% of the cases. --type II: the zygomato-malar artery originates from the branch of the temporo-frontal artery. Its course is either horizontal or caudad. This type accounts for 3% of the cases. Our results confirm those of Ricbourg et al.. Thus, we could not CONFIRM the notion of a racial predominance of typology of the STA in our context. We did not study the dimensions of STA and also the level of its bifurcation. Indeed, it has been largely reported in the literature. These elements constitute the anatomic basis of the surgical use of temporal flaps. The vessel-containing tissue in which travels the STA forms the so-called fascia temporalis superficialis whose plasticity and polyvalency are critical during the procedures of plastic and reconstructive surgeries.

Arterial anatomy of the auricle: its importance for reconstructive surgery

Because the auricle is an organ that is both used as a flap in reconstructive surgery and is often exposed to trauma, the arterial distribution of the auricle is of great importance. The aims of this study were to investigate the auricular branches of the posterior auricular artery (PAA) and superficial temporal artery (STA), to determine the vascular territory of various auricular flaps for flap design. Fifteen human male cadaver auricles were used for this study. A branch of the STA to the ear lobe (lower branch) was present in only five auricles (33%). Branches distributing the tragus were small and short arterioles (middle branch of the STA) which were present in 14 auricles (93%). The upper branch of the STA ascends the ascending helix, giving off sub-branches. Some of these sub-branches traverse to the posterior surfaces of the ear and communicate with branches of the PAA. The upper branch was present in all auricles. In 10 auricles (67%), the PAA terminated on the posterior auricular surface, whereas in five auricles (33%) it continued and distributed to the parietotemporal area. The arterial network which was obvious in the middle region of the posterior auricular surface was formed from the middle branch and some sub-branches of the upper branch of the PAA, which was found in 10 auricles (67%). We are convinced that the PAA is the dominant artery for the auricle and the arterial network of posterior auricular surface is better developed in the middle region than the other regions.

Anatomie de la vascularisation artérielle de l'auricule. Son importance en chirurgie reconstructrice

Résumé La vascularisation artérielle de l'auricule a une grande importance clinique: il est exposé aux traumatismes et volontiers utilisé comme lambeau en chirurgie reconstructrice. Les buts de cette étude étaient l'analyse des rameaux auriculaires de l'artère auriculaire postérieure (AAP) et de l'artère temporale superficielle (ATS) afin de déterminer les territoires vasculaires de différents lambeaux auriculaires. Les auricules de 15 cadavres d'hommes adultes ont été utilisés pour ce travail. Un rameau auriculaire inférieur de l'ATS destiné au lobule de l'auricule était présent sur seulement 5 auricules (33,3%). Les rameaux auriculaires moyens de l'ATS destinés au tragus étaient petits et courts; ils étaient présents sur 14 auricules (93,3%). Le rameau auriculaire supérieur de l'ATS cheminant devant l'hélix lui donnait quelques rameaux. Quelques-uns traversent le pavillon, vers la face postérieure et communiquaient avec les rameaux auriculaires de l'AAP. Le rameau auriculaire supérieur de l'ATS était présent sur tous les auricules. Sur 10 auricules (66,6%), l'AAP se terminait à la face postérieure de l'auricule. Sur 5 auricules (33,3%), cette artère se poursuivait et se distribuait à la région pariéto-temporale. Le réseau artériel, bien formé dans la région moyenne de la face postérieure de l'auricule, était constitué par le rameau auriculaire moyen de l'AAP et de quelques artérioles provenant de son rameau supérieur, ce qui a été parfaitement retrouvé sur 10 auricules (66,6%). Nous avons ainsi montré que l'AAP est l'artère principale de l'auricule et que le réseau artériel de la surface auriculaire postérieure est beaucoup mieux développé dans la partie moyenne que dans les autres régions de l'auricule.

     

Arterial supply to the thyroid gland and the relationship between the recurrent laryngeal nerve and the inferior thyroid artery in human fetal cadavers

The aim of this study was to identify the arterial supply to the thyroid gland and the relationship between the inferior thyroid artery (ITA) and the recurrent laryngeal nerve (RLN) in fetal cadavers using anatomical dissection. The anterior necks of 200 fetuses were dissected. The origins of the superior thyroid artery (STA) and the ITA and location of the ITA in relation to the entrance of the thyroid lobe were examined. The relationship between the ITA and the RLN was determined. The origins of the STA were classified as: external carotid artery, common carotid artery (CCA), and the thyrolingual trunk. The origins of the ITA were the thyrocervical trunk and the CCA. The ITA was absent on the left side in two cases. The relationship of the RLN to the ITA fell into seven different types. Type 1: the RLN lay posterior to the artery; right (42.5%), left (65%). Type 2: the RLN lay anterior to the artery; right (40.5%), left (22.5%). Type 3: the RLN lay parallel to the artery; right (11.5%), left (7%). Type 4: the RLN lay between the two branches of the artery; right (1%), left (3.5%). Type 5: The extralaryngeal branch of the RLN was detected before it crossed the ITA; right (4.5%), left (0%). Type 6: the ITA lay between the two branches of the RLN; right (0%), left (0.5%). Type 7: the branches of the RLN lay among the branches of the ITA; right (0%), left (0.5%). The results from this study would be useful in future thyroid surgeries. Clin.

Systematic Analysis of the Smooth Muscle Wall Phenotype of the Pharyngeal Arch Arteries During Their Reorganization into the Great Vessels and Its Association with Hemodynamics

Early outflow morphogenesis is a critical event in cardiac development. Understanding mechanical and molecular based morphogenetic relationships at early stages of cardiogenesis is essential for the advancement of cardiovascular technology related to congenital heart defects. In this study, we pair molecular changes in pharyngeal arch artery (PAA) vascular smooth muscle cells (VSMCs) with hemodynamic changes over the course of the same period. We focus on Hamburger Hamilton stage 24–36 chick embryos, using both Doppler ultrasound and histological sections to phenotype PAA VSMCs, and establish a relationship between hemodynamics and PAA composition. Our findings show that PAA VSMCs transition through a synthetic, intermediate, and contractile phenotype over time. Wall shear stress magnitude per arch varies throughout development. Despite distinct hemodynamic and fractional expression trends, no strong correlation was found between the two, indicating that WSS magnitude is not the main driver of PAA wall remodeling and maturation. While WSS magnitude was not found to be a major driver, this work provides a basic framework for investigating relationships between hemodynamic forces and tunica media during a critical period of development.
