The maxillary sinus is an anthropological landmark because of difference of volume of maxillary sinus among persons of different ethnic origin. This study was undertaken to provide morphological characteristics of Korean's maxillary sinus. The size and volume of maxillary sinus were measured in 44 Korean skulls 23 males and 21 females from cadaver. The shapes of the maxillary sinus were classified according to Anagnostopoulou et al. (1991) and the sizes of the medial antral wall area of the maxillary sinus were classified according to Fernandes (2004b). The mean volume of maxillary sinus was 12.83+/-5.41 cm3, which was significantly different between males and females. Bilateral symmetry of the volume of the maxillary sinus was observed in the 70% of the specimens. The width of maxillary sinus was 26.59+/-4.96 mm. The height of maxillary sinus was 26.65+/-6.16 mm. The anteroposterior length was 32.84+/-4.96 mm. The anteroposterior length measured on C-Arm radiography was 36.99+/-4.72 mm. The shape of maxillary sinus was semi-ellipsoid and the majority (50%) of the shape of medial antral wall area of maxillary sinus was the type of small. The results of this study could be useful to clarify the anthropological characteristics of the maxillary sinus in Korean, and to provide an index of ethnic classification for the medial antral wall area.

This study aims to investigate the anatomical information of the sphenopalatine foramen with special reference to the bleeding control of the sphenopalatine artery and to the blockage of the pterygopalatine ganglion during functional endoscopic sinus surgery. Forty-three midsagittal sectioned Korean heads were used in the study. The mucosa on the lateral nasal wall was removed for showing the sphenopalatine foramen. The shapes of the sphenopalatine foramen were classified by 4 types. Angle from the akanthion and distances from akanthion, conchae, sphenoidal sinus and greater palatine foramen were measured. The sphenopalatine foramen was frequently found as oval shape and bilateral symmetry of 28.6%. The vertical length was 5.5 mm, the horizontal length was 5.3 mm. The most anterior point of the sphenopalatine foramen was located on 54.4 mm few and angles were between 15.9degrees and 22.1degrees from akanthion. The distances were 36.2 mm from anterior end of middle nasal concha, 6.2 mm from posterior end of middle nasal concha, 27.2 mm from greater palatine foramen. The uppermost point of the sphenopalatine foramen was located on 22.3 mm from the most superoanterior end of the sphenoidal sinus, 18.6 mm from the lowermost end of the sphenoidal sinus. This study could be useful to provide the confidence about the location of the sphenopalatine foramen during functional endoscopic sinus surgery.

OBJECTIVE: The goal of this study was to evaluate the clinical course of total hysterectomized patient with benign gynecologic disease using minilaparotomy. METHODE: 45 benign gynecologic diseased patients who hysterectomized with Pfannelstiel's skin incision and PCA (patient controlled analgesics). 30 patients were laparotomized, and 15 patients were minilapartomized. We analyzed the data of this patients for age, parity, duration of operation, the weight of the uterus, change of the hemoglobin, removal time of foley catheter, starting time of regular diet, initial time of ambulation and discharge date. RESULT: Minilaparotomy hysterectomized patients have lesser bleeding and show more rapid recovery of bowel movement and bladder function. And they experience lesser pain than the other group. CONCLUSION: Minilaparotomy is a safe and feasible route of hysterectomy for a selected group of patients.

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.

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.
