The blow-out fracture can be reconstructed by various autogeneous and alloplastic material. Particulate, nonresorbable hydroxyapatite is currently one of the choice of implant material available for reconstruction of blow-out fracture. Hydroxyapatite is radiopaque ceramic, physically and chemically similar to enamel and cortical bone. It is a biomaterial derived from natural corals to use as a bone graft substitute. And we looked into the clinical usefulness of 2 type of hydroxyapatite with their advantages and disadvantages in reconstruction of blow-out fracture. 183 patients with blow-out fracture who underwent surgical reconstruction with two types of hydroxyapatite from March 1933 to July 1977 have been analyzed the results of surgical reconstructions, and have been followed up for more than a year. And the condition of formerly inserted hydroxyapatite was observed in the patients who needed 2nd surgical reconstruction due to the enophthalmos. The disadvantages of hydroxyapatite are fragility, size and contour limitations. In spite of these demerits, hydroxyapatite can be one of the prospective materials to reconstruct orbital floor. Through the clinical experiences for 5 years, we have not found any of complications of exposure, infection, and foreign body reaction. Low rates of diplopia, limitation of ocular movement, and enophtalmos was observed. Hydroxyapatite was well adherent to adjacent orbital bone in most patients who needed secondary reconstruction for enopthalmos. In conclusion, our study shows that the availability of hydroxyapattite in reconstruction of blow-out fracture is recommendable, with low complication rates. Hydroxyapatite important appears to be well tolerated, and provides useful alloplastic prosthesis with few problems in reconstruction of blow-out fracture.

Reconstruction of partial ear defect to approximate the opposite normal ear is actually very difficult. Because the patterns of partial ear defect (site, shape and size of defect) are extremely variable, the operative method on each case should be changed. In an effort to overcome these problems, many reconstructive methods have been reported so far. We experienced 11 cases of partial ear defect from September, 1995 to August, 1996 and different reconstructive methods were applied In this study, the most common cause of partial ear defect was trauma (9 cases) and the most common site was middle part of ear helix. The defects were varying from 1x2 cm to 1.5x5 cm in size. The methods that has been used for reconstruction of ear defect include direct closure, helical chondrocutaneous advancement flap, Dieffenbach's method, retroauricular flap, tubed bipedicled flap and so on. We could get to know the merits and demerits of each method through this follow up study. So authors obtained the several basic conclusions about the merits and demerits of each method and standard of method selection in various patterns of ear defects. From analysis of the cases with review of literature, the our conclusions are as follows. 1. If the size of de(tract is small and the patient does not want to have two times of operation, direct closure can be done with good results. 2. If the defect exists on ear auricle confuted to helix and if there are no or small amount of associated cartilage defect, tubued bipedicled flap seems to be proper. 3. With the ear auricle defect confined to helix, especially helix of upper ear auricle, helical chondrocutaneous advancement flap can brought tile best result, though it has disadvantage of being decreased in its size 4. If there are extensive defect on ear auricle extending over scapha and antihelix, retroauricular flap can be done with good results. 5. In the ear auricle defect acompanying considerably large cartilage loss, Dieffenbach's method is thought to be proper.

9.Anatomy Cartoon for Common People.

Anatomy must be known not only by medical students but also by health science students. Furthermore, common people had better know anatomy because anatomy helps them keep their own health and dig up their own curiosity of body. It is desirable that common people learn morphology and function of the human body using easy, familiar, and interesting anatomy cartoon. But we could not find such a Korean anatomy cartoon, so that we tried to make anatomy cartoon for common people as follows. For anatomy cartoon, anatomist decided anatomy contents to write sentences. Based on the sententces, raw illustrations of anatomy cartoon were drawn on the paper with a pencil. Final illustrations of anatomy cartoon (931 cuts) were drawn on Adobe Illustrator of the personal computer. In addition, anatomy comic cartoon composed of four cuts (100 episodes) were drawn. Anatomy term explanations, anatomy photographs, and anatomy movies were created and hyperlinked with the anatomy cartoon, all of which were distributed through homepage (anatomy.co.kr), CD title, and book. The anatomy cartoon will be helpful not only to anatomy study of the common people and health science students but also to preliminary anatomy study of the medical students.

Objective: We investigated whether circle of Willis (COW) morphology on 3D time-of-flight (TOF)
MR angiography differs between young normal subjects, older normal subjects, and patients with
carotid atherosclerotic plaques. Methods: One hundred seventy-seven subjects were grouped according
to age into a young group (20 – 40 years; n = 91) and an older group (> 60 years; n = 86). Subjects
underwent brain MR examination as part of a health check-up. Fifty-three patients with carotid
atherosclerotic plaque were also included for evaluation in this study. COW morphology on 3D TOF
MR angiography was analyzed in terms of completeness or incompleteness of the anterior and posterior
components of the circle and completeness of the circle. Results: An incomplete pattern of anterior
circulation was significantly more common in carotid atherosclerotic plaque patients (20.7%) than
normal older subjects (5.5%) (p < 0.01). A complete posterior circulation pattern was more frequent
in normal young subjects (46.5%) than in normal older subjects (16.5%) or the patient group (18.9%)
(p < 0.01). Of patients with carotid artery stenosis, 18.9% had a bilateral incomplete connection and
were significantly more likely to have an incomplete pattern than normal young (2.3%) or normal
older subjects (2.2%) (p < 0.001).
Conclusion: Young, healthy subjects were significantly more likely to have a complete pattern of posterior
circulation than older subjects. Patients with carotid atherosclerotic plaques were significantly more
likely to have incomplete anterior circulation and an incomplete circle than young, normal subjects.
