Abstract:
The superficial temporal artery and the occipital artery on both side of 50 Chinese adult cadavers were dissected and the course and distribution of these two arteries were studied and their length, external diameter, internal diameter and the thickness of the walls were meassured.1. The main stem of the superficial temporal arteries runs upward and forward in front of the orifice of the external auditory meatus at an angle on the average of 12.44?8.16? away from the vertical line. This artery was found in 68.68?4.66％ situated before the superficial temporal vein and auriculo-temporal nerve. The average length of the main stem is 3.88?1.04cm; the external diameter 1.64?0.42mm; the internal diameter 1.19?0.10 mm and the thickness of its wall 0.23?0.08 mm. 2. The parietal branch of the superficial temporal artery runs upwards and backwards to the vertex of the skull at an angle of 25.92?10.09 away from the vertical line. The average length is 7.56?1.63 cm. It may be classified into three typs: (1) the single-stem type (2) the bifurcate type (3) the double-stem type. The average external diameter of the branch is 1.24?0.28mm, the internal diameter 0.91?0.19mm, the thickness of its wall 0.17?0.06 mm. There arr 7.45?2.71％ of the cases that the internal diameter is less or equal to 0.5 mm.3. The frontal branch of the superficial temporal artery runs forwards and upwards to the frontal tuber or above the lateral-upper angle of the orbital, then turns upwards to the vertex of the skull. Its average external diameter is 1.31?0.35mm; the internal diameter, 0.91?0.29 mm, and the thickness of its wall, 0.18?0.08mm.4. The Occipital artery runs out to the skin through the fascia between the trapizius and sterocleidomastoid, but sometimes it porferates the muscular fibers of one of these two muscles. The point from which it runs out is located at 2.23?1.12 cm below the external occipital protuberans and 3.41?0.85cm lateral to the midline. Three types of the branching patterns were found: the main-stem, the bifurcate and the plexiform type. The average external dianeter of the occipital artery is 1.47?0.14 mm, the internal diameter,1.13?0.29 mm, and the thickness of its wall, 0.18?0.08mm.
