OBJECTIVETo study the anatomy and preparation methods of an improved lateral arm free flap (LAFF) for the future clinical application.

METHODSTwenty-two adult upper extremities from cadavers after injected with red latex through common carotid arteries were used. The course, branches, distribution and variations of the blood vessels and nerves of the improved LAFF were observed. The outer diameters of the vessels were measured.

RESULTSThe mean length of vascular pedicle of the improved LAFF was (14.85 ± 1.28) cm, significantly more than that (5.46 ± 2.60) of traditional LAFF (t = -8.483, P < 0.001). The mean outer diameters of pedicle arteries and veins in the improved LAFF were (2.24 ± 0.66) mm and (2.22 ± 0.52) mm, significantly more than those (1.15 ± 0.21 and 1.26 ± 0.23) in traditional LAFF (t = -8.690, P < 0.001; t = -15.057, P < 0.001), respectively.

CONCLUSIONThe improved LAFF has a longer vascular pedicle and larger artery and vein in diameter than conventional LAFF, and is more suitable for the repair of the small and medium-sized defects of the head and neck.

OBJECTIVETo improve a better method to achieve the upper arm's circumferential harmony by using adjacent aesthetic unit combined upper arm liposuction.

METHODSLiposuction of upper arm, axilla and part of the scapula area was performed on 88 cases at one stage from January 2007 to March 2013.

RESULTSAll the cases achieve satisfactory results. The circumferential curve is smooth and elegant. No severe complication happened.

CONCLUSIONSThis method proved to be safe and effective and can be accomplished in one stage.

The weight, height and mid-upper-arm circumference (MUAC) were measured in 159 women of reproductive age between June and November 1991 in four remote valleys in the Eastern Central Highlands of Irian Jaya, Indonesia. The average weight was 42.3 +/- 5.2 kg and 26% weighed less than 40 kg. The average height was 141.3 +/- 9.1 cm and 30% were shorter than 140 cm. By the MUAC measurement, the nutritional status was considered to be inadequate (MUAC less than 23 cm) in 58% of the women. 8% of the women were observed to be visibly pregnant and 43% were lactating. In the same period 112 women in the Yamil valley were visited at home. They had given birth to 331 children, of whom 83 had died before the age of five years, i.e. a child mortality rate of 251 per 1000 births. Nearly half of the mortality (45%) occurred shortly after birth. PIP: To obtain baseline information to assist a new nurse-midwife, weight, height, and mid-upper-arm circumference (MUAC) were measured in 159 women of reproductive age in four remote valleys (Yamil, Hey, Moruman, and Bomela) in the Eastern Central Highlands of Irian Jaya, Indonesia, in 1991. Average weight was 42.3 +or- 5.2 kg; 26% weighed less than 40 kg. Height averaged 141.3 +or- 9.1 cm; 30% were shorter than 140 cm. The MUAC was less than 23 cm (indicative of inadequate nutrition) in 58% of the women and 20 cm or less (malnutrition) in 16%. The international reference standards for weight, height, and MUAC are 56.6 kg, 163.7 cm, and 26 cm. 8% of women appeared pregnant and 43% were lactating. Home visits to 112 women in the Yamil valley revealed they had given birth to 331 children, 83 of whom had died before 5 years of age (child mortality rate, 251/1000 births). Since maternal food supplementation aimed at increasing birth weight would lead to more complicated deliveries in stunted mothers, the most feasible strategy is a nutrition program for schoolchildren--the mothers of the next generation.

The superficial brachial artery (SBA), a branch of the axillary artery, is one of the most common arterial variations in this area. While it is more vulnerable to accidental arterial injection or injury, it could be useful for the nourishment of a medial arm skin free flap. To analyze the relationship between the SBA of axillary origin and segmental variation of the axillary artery, we dissected 304 arms of Korean cadavers. We found an SBA of axillary origin in 12.2% of cadaveric arms. Unilateral occurrence was detected in 16 cadavers and bilateral in 10. SBAs gave rise to radial and ulnar arteries in the cubital fossa (8.9%), continued in the forearm as the radial artery (2.3%), or ended in the upper arm (1.0%). The SBA ended as ulnar artery was not found in any of the cadavers. The bifurcation of the SBA into the radial and ulnar arteries, presence of an SBA that ends in the upper arm, and the lack of continuation as the ulnar artery are characteristics of SBAs in Korean cadavers.

BACKGROUND: The ability to explore the anatomy has improved our appreciation of the brachial anatomy and the quality of regional anesthesia. Using real-time ultrasonography, we investigated the cross-sectional anatomy of the brachial plexus and of vessels at the axillary fossa in Koreans. METHODS: One hundred and thirty-one patients scheduled to undergo surgery in the region below the elbow were enrolled after giving their informed written consent. Using the 5-12 MHz linear probe of an ultrasound system, we examined cross-sectional images of the brachial plexus in the supine position with the arm abducted by 90degrees, the shoulder externally rotated, and the forearm flexed by 90degrees at the axillary fossa. The results of the nerve positions were expressed on a 12-section pie chart and the numbers of arteries and veins were reported. RESULTS: Applying gentle pressure to prevent vein collapse, the positions of the nerves changed easily and showed a clockwise order around the axillary artery (AA). The most frequent positions were observed in the 10-11 section (79.2%) for the median, 1-2 section (79.3%) for the ulnar, 3-5 section (78.4%) for the radial, and 8-9 section (86.9%) for the musculocutaneous nerve. We also noted anatomical variations consisting of double arteries (9.2%) and multiple axillary veins (87%). CONCLUSIONS: Using real-time ultrasonography, we found that the anatomical pattern of the major nerves in Koreans was about 80% of the frequent position of individual nerves, 90.8% of the single AA, and 87% of multiple veins around the AA.

In 1951, in the midst of the Korean War, artist Lee Quede produced anatomical drawings to teach artistic anatomy to his student Lee Ju-yeong while interned in the Geoje prison camp. Comprising 2 books and spanning over 48 pages, 74 drawings were produced alongside explanations in a textbook format. The table of contents was ordered starting from body proportions, then the skeleton, the muscles, and the head. By part, there were 4 drawings of the trunk, 51 of the head, 7 of the arms, 9 of the legs, and 3 of the full body. Though the drawings of the head and face are both high in number and in detail, there were many errors in his depictions of the bones, and the boundaries between the structures of his muscle drawings were drawn so unclearly as to be indistinguishable. The essential forms, proportions and movement are included, but his disproportionate dedication to the head and the incoherent way that the book is arranged with no relevance to its table of contents leave something to be desired. It is regrettable that Lee Quede's return to North Korea meant that his drawings were not widely used, but despite this, I believe that these are invaluable documents in assessing the influence of Japanese artistic anatomy at the time, as well as the introductory circumstances of Korean artistic anatomy.
