The Position of Mandibular Canal in the Sections of the Mandible / 체질인류학회지

The complications and sequelae after the mandibular surgery are related to inferior alveolar neurovascular bundles, which pass through the mandibular canal. The knowledge of their positions would decrease the risk of mandibular surgery dramatically and would be used for the development of the new surgical techniques. This study was undertaken to clarify the anatomical position of mandibular canal for the mandibular surgery. Forty four mandibules (23 males and 21 females average 66.5 years) obtained from the collection of Hanyang medical college were studied. The location of mandibular canal in the sections between premolars and molars were measured. The obtained results were as follows; At first, the mandibular canal lay lingual to the distal part of the body of the mandible. It then ran anteriorly and to the buccal part of the mandible between the first and the second premolars. In the sections between premolars and molars, the distance between the mandibular canal and the lower border of mandibular body was 8.9+/-1.9 mm at the position of the first molar, the distance between the deepest point of the alveolar socket and the mandibular canal was 9.5+/-3.5 mm at the second molar, which was the narrowest point. The results of this study would be useful to decrease the risk of the mandibular surgery and to develop the new techniques for mandibul surgery in the field of the dentistry and maxillofacial surgery.

Morphometry of the Korean Nasal Turbinates / 체질인류학회지

Recently, with the increasing interests in the endoscopic nasal surgery, it is essential for practitioners to have detailed knowledges of the anatomical structures for the successful surgery. This study was undertaken to provide morphological information of the nasal turbinates as anatomical reference during endoscopic nasal surgery. A total of 43 adult cadaver heads were bisected midsagitally and evaluated morphometrically. The results were as follows: The highest nasal turbinatee were observed in 66.7% of the case. After removal of the mucosa, the distances from the akanthion to the anterior end of superior, middle, inferior nasal turbinate were 46.75 mm, 38.23 mm, 18.51 mm respectively. The distances from the akanthion to the posterior end of superior, middle, inferior nasal turbinate were 55.11 mm, 54.72 mm, 50.26 mm respectively. The lengths of the superior, middle, inferior nasal turbinate were 22.20 mm, 40.14 mm, 40.97 mm respectively. The detailed measurements of the nasal turbinates performed in this study may provide useful anatomical landmarks for the endonasal endoscopic surgery.

A Case of Multiple Masses after Suction-Assisted Lipectomy

Suction-assisted lipectomy has become an increasingly popular procedure, being one of the most frequently performed aesthetic procedures in Korea. Serious complications of suction-assisted lipectomy are uncommon but aesthetic problems are often troublesome. Here we report a patient with multiple abdominal masses composed of fat necrosis with fibrosis after suction- assisted lipectomy that was treated with excision. We also discussed and deduced the cause of its complication because plastic surgeons are liable to overlook this rare complication.

Effects of the Recombinant Human Epidermal Growth Factor on Full-thickness Wound of the Rat Skin

The wound healing effect of topical application of the recombinant human epidermal growth factor(rhEGF) on full-thickness dermal injury was investigated. Two full-thickness excisions were made on the back of the experimental animals. The rhEGF was applied twice a day and the rate of wound closure was measured every day for 14 days. On the seventh postoperative day, the histological findings of epithelization and granulation were examined by Massons tichrome stain, and immunohistochemical staining for proliferating cell nuclear antigen (PCNA) and alpha-smooth muscle actin(alpha-SMA). The wound size was a significant reduction in the rhEGF treated groups as compared with the control group (p<0.05). However, there was no statistical difference in the wound size among the concentrations of the rhEGF treated group. Histological examination revealed that epithelization and granulation was increased significantly in the rhEGF group compared to control group (p < 0.01, 0.05). PCNA and alpha-SMA immunoreactive cells were observed at the margin of wound and the rhEGF treatments significantly increased the number of PCNA and alpha-SMA immunoreactive cells as compared to those of control group (p < 0.01, 0.05). Taken together, these findings suggest that rhEGF enhance the epithelial wound healing by the stimulate of cell proliferation. The wound contraction might be also affected by rhEGF application.
