Abstract

Objective: 1. Giant micro-anatomy and vascular cast on the human body and maxillofacial, the reference applied anatomy for clinical cosmetic surgery. Explore the human body and maxillofacial vascular digitized, three-dimensional visualization of the maxillofacial blood vessels in and around the structure adjacent relationship. Materials and methods: 1. Giant micro anatomy: normal adult head and neck specimens carotid artery perfusion red latex red solution or Mercurochrome nose from the lower edge of the mandible, the leading edge of the tragus to the naked eye and under the operating microscope the back Deep and anatomical layers, starting at the outside diameter of the observation and recording of maxillofacial vascular running, branches, distribution, anastomosis and concomitant. Vascular cast: three cases of normal adult head and neck specimens (fresh), carotid artery pressure injected red perchlorethylene filler, observed by corrosion after maxillofacial source of the blood vessels, course, branch distribution agreement and accompanied situation. Angiography and three-dimensional reconstruction: three fresh adult head and face specimens, perfusion CT scan forward after scanning through the carotid artery perfusion gelatin - lead oxide contrast agent, respectively, continuous scanning radiography and CT scan data. Dicom format, import Mimics software, shaded surface display method (shaded surface display, SSD) of the skull, maxillofacial vascular and facial contour display of three-dimensional reconstruction and visualization were observed adjacent to the three-dimensional relationship. Results: 1. Anatomical features maxillofacial maxillofacial vascular arteries comes mainly from the facial artery, ophthalmic artery, the branch of the maxillary artery and the superficial temporal artery. ⑴ facial artery is the main breadwinner of the cheek, lips and chin, constant initiation site, but its running distributed terminate parts variable facial artery starting at the outside diameter of 2.3 ± 0.4mm was 100%. ⑵ the submental artery are constant branch of the facial artery, starting outside diameter of 1.8 ± 0.6mm, the rate was 100%. (3) lower lip artery starting outside diameter of 1.2 ± 0.4mm, rate of 75%. ⑷ the labial artery initiation site than constant, starting outside diameter of 1.3 ± 0.3mm, the rate was 96.8%. ⑸ nose under the edge of the artery outer diameter of 1.0 ± 0.3mm, the rate was 83.3%. ⑹ nose artery outer diameter of 0.6 ± 0.2mm, the rate was 91.67%. ⑺ lateral nasal artery outer diameter of 0.9 ± 0.2mm, the appearance rate of 91.67%. The inner canthal artery ⑻ outer diameter of 0.6 ± 0.2mm, the rate was 66.67%. ⑼ facial artery masseteric branch starting at the outside diameter of 1.2 ± 0.2mm, a rate of 50%. ⑽ dorsum artery outer diameter of 0.8 ± 0.3mm, the rate was 58.33%. The ⑾ infraorbital foramen infraorbital artery to start external diameter 1.0 ± 0.2mm, the rate was 100%. The ⑿ transverse facial artery outer diameter of 1.8 ± 0.5mm, there was 100%. ⒀ zygomatic orbital artery outer diameter of 1.0 ± 0.3mm, there was 100%. ⒁ supraorbital artery of the supraorbital foramen starting at the outside diameter of 1.0 ± 0.2mm, was 100%. ⒂ supratrochlear artery starting at the outside diameter of 1.3 ± 0.3mm, there was 100%. 2 different research methods show the characteristics of the blood vessels (1) giant micro-dissected: conventional vascular perfusion full line blood vessels clear, easy separation and easy tracking observations vascular branch distribution outside diameter size. ⑵ vascular cast: maxillofacial vascular finer pipeline full, thickness, density and reasonable, artery showed complete specimens of beautiful, bright color, stereoscopic. ⑶. 3D visualization: reconstruction of three-dimensional visualization of anatomical models of the the maxillofacial main artery, the vivid image of the display of maxillofacial vascular space location and the adjacent relationship with the surrounding tissue, can be in any direction rotation observed, in accordance with The design needs to be cut, partial display, simple operation, and flexibility. Conclusions: 1. Through latex reperfusion, vascular cast, gelatin - lead oxide angiography and three-dimensional reconstruction of a variety of methods on the arteries of the maxillofacial system application anatomical reference for clinical cosmetic maxillofacial surgery basis. 2 latex perfusion, vascular casting, gelatin - lead oxide angiography and three-dimensional reconstruction methods can clearly show the maxillofacial's arteries, each with its own characteristics. Gelatin - lead oxide angiography and three-dimensional reconstruction of the establishment of the maxillofacial vascular 3D visualization model, clinical and maxillofacial surgery plastic surgery designed to develop preoperative program of basic research and applied anatomy new method has good development prospects.
