摘要

目的:长期以来,文献一直将下颌骨的动脉供应描述为来自下牙槽动脉这一单一动脉,而且是终末型的。相反,它似乎来自一个广泛而复杂的动脉网络,依赖于舌动脉、面动脉和上颌动脉及其侧支。我们的研究旨在证实和展示下颌骨动脉血管的丰富性,并建立动脉图谱:方法:用不同染料对舌动脉、面动脉和上颌动脉进行选择性注射后,在六个解剖标本中显示了下颌骨的动脉血管。一个标本在上颌动脉水平用彩色乳胶进行动脉内注射,以进行形态计量学研究:结果:对六个解剖标本进行了 18 次选择性动脉注射。对粘膜、肌肉骨膜和髓内血管进行了分析。每条动脉都有明确界定的皮肤黏膜血管区域。面动脉和上颌动脉供应下颌骨从髁突到骨骺的肌肉骨膜血管。舌动脉仅供应副骨和合骨区域的内皮层。面动脉和上颌动脉为下颌角至干骺端提供髓内血管。干骺端的血管则取决于面动脉。髁状突区域未发现染色。对解剖标本进行氯丁橡胶乳胶注射,发现下牙槽动脉和面动脉之间有通透性吻合:结论:下颌骨的动脉血管依赖于上颌动脉、面动脉和舌动脉。这是一个网络脉管系统。这项研究为绘制下颌骨动脉地图提供了可能。下牙槽动脉与面部动脉之间存在吻合,这证实了动态借用血管的存在。对这一动脉系统的了解有助于调整颌面外科护理并预测术中可能出现的并发症。

Arterial vascularization of the mandible and soft tissues. Anatomic study.

Arterial vascularization of the mandible and soft tissues. Anatomic study.

Purpose: The literature has for too long described the arterial supply of the mandible as coming from a single artery, the inferior alveolar artery, and being of the terminal type. Rather, it appears to come from an extensive and complex arterial network dependent on the lingual, facial, and maxillary arteries and their collateral branches. Our study aims to confirm and demonstrate the arterial vascular richness of the mandible and to establish arterial mapping.

Methods: The arterial vascularization of the mandible was revealed in six anatomic specimens after performing selective injections of the lingual, facial, and maxillary arteries with different dyes. A specimen was injected intra-arterially with colored latex at the level of the maxillary artery for a morphometric study.

Results: Eighteen selective arterial injections were performed on six anatomic specimens. The mucocutaneous, musculoperiosteal, and intramedullary vascularizations were analyzed. Each of the arteries has a defined and delimited cutaneo-mucous vascular territory. The facial and maxillary arteries supply the musculoperiosteal vascularization of the mandible from the condyle to the symphysis. The lingual artery supplies only the inner cortex of the parasymphyseal and symphyseal regions. The facial and maxillary arteries provide intramedullary vascularization from the angle of the mandible to the parasymphysis. The vascularization of the symphysis depends on the facial artery. No staining was found in the condyle region. Neoprene latex injection was performed on an anatomic specimen, revealing a permeable anastomosis between the inferior alveolar and facial arteries.

Conclusion: The arterial vascularization of the mandible is dependent on the maxillary, facial, and lingual arteries. This is a network vasculature. This study makes it possible to establish an arterial map of the mandible. The presence of an anastomosis between the inferior alveolar artery and the facial artery confirms the existence of dynamic and borrowed vascularization. Knowledge of this arterial system makes it possible to adapt maxillofacial surgical care and to anticipate possible intraoperative complications.

期刊介绍: Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
