OBJECTIVES The aim of the present study is to provide a detailed macroscopic mapping of the palatal and tuberal blood supply applying anatomical methods and studying specific anastomoses to bridge the gap between basic structural and empirical clinical knowledge. MATERIALS AND METHODS Ten cadavers (three dentate, seven edentulous) have been prepared for this study in the Department of Anatomy, Semmelweis University, Budapest, Hungary, and in the Department of Anatomy of the Medical University of Graz. All cadavers were fixed with Thiel's solution. For the macroscopic analysis of the blood vessels supplying the palatal mucosa, corrosion casting in four cadavers and latex milk injection in other six cadavers were performed. RESULTS We recorded major- and secondary branches of the greater palatine artery (GPA) and its relation to the palatine spine, different anastomoses with the nasopalatine artery (NPA), and lesser palatal artery (LPA) as well as with contralateral branches of the GPA. Penetrating intraosseous branches at the premolar-canine area were also detected. In edentulous patients, the GPA developed a curvy pathway in the premolar area. The blood supply around the maxillary tuberosity was also presented. CONCLUSION The combination of different staining methods has shed light to findings with relevance to palatal blood supply, offering a powerful tool for the design and execution of surgical interventions involving the hard palate. CLINICAL RELEVANCE The present study provides clinicians with a good basis to understand the anatomical background of palatal and tuberal blood supply. This might enable clinicians to design optimized incision- and flap designs. As a result, the risk of intraoperative bleeding and postoperative wound healing complications related to impaired blood supply can be minimized.

分析硬pa和上颌结节的供血量-对皮瓣设计和软组织移植物收获的临床意义（一项人体尸体研究）。

目的本研究的目的是使用解剖学方法并研究特定的吻合术以弥合基础结构和实证临床知识之间的鸿沟，提供and和管状血液供应的详细宏观图。材料与方法在匈牙利布达佩斯的Semmelweis大学解剖学系和格拉茨医科大学解剖学系中准备了10具尸体（3个齿状，7个无牙）。所有尸体都用Thiel的解决方案解决了。为了对供应supply黏膜的血管进行宏观分析，在四个尸体中进行了腐蚀铸造，并在其他六个尸体中进行了乳胶注射。结果我们记录了大p动脉（GPA）的主要和次要分支及其与the脊柱的关系，与鼻artery动脉（NPA）和小pa动脉（LPA）的不同吻合以及与GPA对侧分支的关系。在前磨牙犬区也发现了穿透性骨内分支。在无牙的患者中，GPA在前磨牙区形成了弯曲的路径。还显示了上颌结节周围的血液供应。结论不同染色方法的结合为与pa血供应有关的发现提供了启示，为设计和执行涉及硬pa的外科手术提供了有力的工具。临床相关性本研究为临床医生了解understand和肺部血液供应的解剖背景提供了良好的基础。这可能使临床医生能够设计优化的切口和皮瓣设计。结果，与血液供应受损有关的术中出血和术后伤口愈合并发症的风险可以最小化。
