    Notes: The maxillary blood supply is essential for preserving the vitality of the affected maxillary region, integration of the grafting material, and wound healing such as following sinus floor elevation. Although it is well established that edentulous maxillae demonstrate a decreasing vascularity as bone resorption progresses, the vascular conditions relevant to sinus floor elevation procedures have not been investigated yet. This study deals with maxillary arteries relevant to sinus floor elevation surgery and examines the vascularization of the lateral maxilla after tooth loss. The vessels of the lateral maxilla of 18 maxillary specimens (10 male, 8 female, mean age 67 years) were prepared anatomically and the local main arteries, the number of macroscopically discernible branches and anastomoses, their calibers, and the distance between the caudal main branches and the alveolar ridge recorded. The lateral maxilla is supplied by branches of the posterior superior alveolar artery (PSAA) and the infraorbital artery (IOA) that form an anastomosis in the bony lateral antral wall, which also supplies the Schneiderian membrane. This intraosseous anastomosis was found in all of the specimens. Eight of 18 also showed an extraosseous anastomosis between PSAA and IOA, vestibular to the antral wall, giving off an average of 3 branches cranially and 5 branches caudally. The two anastomoses form a double arterial arcade to supply the lateral antral wall and, partly, the alveolar process. The PSAA had a mean caliber of 1.6 mm and exhibited an average of 2 endosseous and 1 extraosseous branches. The IOA had a mean diameter of 1.6 mm and showed an average of 1 endosseous and 3 extraosseous branches. The mean distance between the intraosseous anastomosis and the alveolar ridge was 19 mm in 2 defined measuring sites. Its mean length was 44.6 mm. The epiperiosteal vestibular anastomosis was situated further cranially, at a mean distance of 23 to 26 mm from the alveolar ridge and had a mean length of 46 mm. The rather large caliber of the vessels supplying the lateral antral wall seems to be crucial to the fact that the periosteal blood supply is maintained even in severe maxillary atrophy and after complete disappearance of the centro-medullary vessels.

    Notes: The latissimus dorsi muscle (LD) has been the subject of numerous studies, especially because of its variety of possible applications in plastic and reconstructive surgery.The clinical use of functional electrical stimulation (FES) and cardiomyoplasty has raised completely new questions in recent years. It was the aim of our study to find an optimal model for animal experiments for this cardiosurgical method, in which the LD is completely removed from its origin and transferred into the thorax. For this purpose, we compared the LD's arterial supply in animals used in experimental surgery, the sheep, dog, and pig, with the LD's supply in human.For studying the arteries of the LD macroscopically and by X-ray, we used an injection solution of latex and barium sulfate. After injection of the solution the vascularization was photographically documented. Subsequently, the muscle was detached from the neurovascular pedicle and prepared for radiological examination of the arterial vascularization.The planimetric computer-assisted identification of the various areas supplied by arterial branches was based on these radiograms. In order to also assess the weight of the supplied parts, the muscles were gravimetrically analyzed.The study showed that the blood supply in pig is very similar to that of man. This species, therefore, would be best suited for experimental cardiomyoplasty. © 1994 Wiley-Liss, Inc.
