The malar bones are major determinants of mid-facial shape. In an oriental population, malar prominences are considered an unpleasing and undesirable feature because they give the face a triangular shape and may produce an emaciated and sunken appearance. There are two main operative approaches to malarplasty. One is a coronal approach and the other is a intraoral approach. The former possess advantages of symmetricity, accuracy and superiorly, medially and posteriorly aesthetical transposition of the malar bone. However, it has drawbacks such as a long visible scar on the scalp and extensive operation. Though the latter is a simple method avoiding a visible scar, it has some problems of asymmetricity, cheekdrooping, partial transposition of the malar complex and difficulty of aesthetic transposition. The authors intended to perform intraoral malarplasty for symmetrically aesthetic transposition of the whole malar bone without cheekdrooping. From February 1996 to January 1999, 9 female patients with prominent malar complex, in whom the coronal incision was objectionable, had intraoral malarplasty performed with 2-point fixation after L-shaped osteotomy involving the zygomatic process of maxilla, resulting in symmetric and aesthetically desirable three dimensional transposition of the malar bone.

PURPOSE: To see the stability and error in the diffusion-weighted magnetic resonance (MR) imaging technique in the experimental models and to observe the signal intensities in the early cerebral lesions of the animal models. MATERIALS AND METHODS: Diffusion coefficients of acetone and distilled water were measured by diffusion-weighted MR image and were compared with actual values. Differentiation of diffusion from perfusion were done at the resin flow phantom. The signal intensities caused by early parenchymal changes were measured in normal, hypovolemic, and embolic, and dead animal models by using diffusion-weighted image and compared with pathoIogic finding and vital staining. RESULTS: Diffusion coefficients of acetone and distilled water were 4.48 x 10-3 and 2.72 x 10-3 which were very close to the actual values. Diffusion-weighted MR image obtained at flow phantom was not affected by flow (perfusion) at the 100-400 of b-factor range. Animal study done at that b-factor range revealed a significant signal difference between the left and right sides only at the embolic model induced by polyvinyl alchol particles (p<0.05). These changes were not detected in microscopic finding but could be identified in vital staining. CONCLUSION: Diffusion-weighted MR image can be used to detect early parenchymal change when the appropriate b-factor range was applied.

An upward slant of palpebral fissure is usually said and believed to be a hallmark of Mongolian race. The slant of palpebral fissure is very important in the evaluation and treatment of patients with congenital deformities. And these statistical values of slant of palpebral fissures are very helpful in case of traumatic or congenital lateral canthal deformities and upper face lift or forehead lift. The normal values of slant of palpebral fissures are variable according to races, sex and ages. Even if upward slant of palpebral fissure are one of characteristic features of Koreans, there are a few articles concerning them in Korea yet, unfortunately. So, we have inevitably utilized the Caucasian or Japanese statistical data. Authors measured the slant of palpebral fissure in Koreans, and statistically analyzed them in 996 individuals including 468 males and 528 females. The mean values of slant of palpebral fissure was 8.5+/-2.0degreein males and 8.8+/-2.5degreein females. The mean values of slant of palpebral fissure was greater in female than male. However, there was no statistical difference between males and females. The slant of palpebral fissure reached the peak level at childhood and teenagers in a great portion. After the peak level, the changing pattern of slant of palpebral fissure was decreasing gradually. In summary, we consider 8.65degreeas normal standard value of slant of palpebral fissure when performing lateral canthal surgery in Koreans.
