1.Reliability of Transrectal Ultrasonography in Diagnosis of Uterine Cervical Carcinoma.
Journal of the Korean Radiological Society 1994;30(1):159-168
PURPOSE: To evaluate the relibility of transrectal ultrasonography (TRUS) to define adult female genital organ and to diagnose and stage the cervical carcinomas. METHODS AND MATERIALS: After analysis of normal ultrasonographic anatomy of female pelvis in ten healthy women, I performed TRUS in thirty patients of uterine cervical carcinomas by rotating the 5 MHz electronic linear array transducer(SL2, Siemens, Erlangen, Germany) along the reference sagittal plane in the middle of uterine cervix & vagina. The results of TRUS were analyzed and compared to FIGO, surgical pathology, CT and MRT, ect. RESULTS: TRUS allowed good visualization of the uterus, uterine cervix, parametrium, vagina, anterior rectal wall, walls of the urinary bladder, and uterine cervical carcinomas. The accuracy of staging with TRUS was 83%, compared with the accuracy of 67% for clinical staging according to the criteria of the International Federation of Gynecotogy and Obstetrics(FIGO). For extent of parametrial involvement, the sensitivity of TRUS was 93%, with the specificity of 86% and the diagnostic accuracy of 89%. The same reliability parameters for clinical evaluation were 71%, 79%, and 75% respectively. CONCLUSION: Above findings suggest that low-cost TRUS could be usefully applied to pretreatment evaluation of patients with uterine cervical carcinoma.

2.Cephalometric study of obstructive sleep apnea patients in the upright and supine positions.
Korean Journal of Orthodontics 1995;25(6):655-664
Sixty male patients with polysomnographically documented OSA were included in this study. A pair of cephalograrns were obtained in the upright and supine positions. In the supine position, the ANB angle, lower facial height and the cross-sectional area of soft palate increased and there was a decrease in the vertical airway length and oropharynx cross-sectional area. Positional changes did not affect the cross-sectional area of tongue, but the cross-sectional area of the oropharynx decreased in the supine position. The obese group had higher AI and RDI. Maxillary unit length, C3-H, the cross-sectional areas of tongue, soft palate and oropharynx were significantly greater in the group Obese than in non-obese group. No correlation was noted between the mandibular unit length and OSA severity. The group of small mandibular unit length showed shorter lower facial height and maxillary unit length, and smaller cross-sectional area of tongue than the long mandibular unit length group. Hyold bone positioned more inferiorly and cross-sectional area of nasopharynx decreased as the OSA severity increased.

4.The Role of Endorectal Ultrasonography in the Follow-up Evaluation of the Uterine Cervical Carcinomas in Intra-arterial Cisplatin Chemotherapy.
Journal of the Korean Radiological Society 1994;30(6):1135-1140
PURPOSE: lntra-arterial cisplatin infusion chemotherapy delivers higher concentration of this therapeutic agent to the limited area of cervical carcinoma. We evaluated the role of endorectal ultrasonography (ERUS) in the analysis of the tumor response to this chemotherapy. MATERIALS AND METHODS: ERUS was done in 20 patients of cervical carcinomas limited to the pelvis by rotating the 5 UHz linear arraytransducer along the reference sagittal plane in the middle of uterine cervix and vagina. We examined and compared the change of tumor size and morphology on ER US, before, during and after intra-arterial cisplatin (50 mg/m2) chemotherapy through internal lilac artery near uterine arterial branching. Colposcopy and radical hysterectomy with pelvic lymphadenectomy were performed in all patients, and ERUS findingswere compared with those findings. RESULTS: ERUS correlated well with surgery in the estimation of preoperative tumor size and morphology. Tumor reduction rate on ERUS (100-the largest area of the preoperative tumor/the largest area of the initial tumor) was as follows: more than 75% decrease of the original size in 3 patients, 75% -50% in 6 patients, 50%-25% in 8 patients, and less than 25% in 3 patients. Hyperechoic reflecting areas were noted in 4 patients, which corresponded to gaseous necrosis on postoperative pathology. CONCLUSION: ERUS is helpful to evaluate the morphologic change of cervical carcinoma limited tothe pelvis in intra-arterial cisplatin chemotherapy.

5.Sonourethrography in the Evaluation of Anterior Urethral Strictures.
Journal of the Korean Radiological Society 1994;30(4):731-738
PURPOSE: To determine the reliability of sonourethrog raphy (SUG) in the evaluation of male anterior urethral strictures. MATERIALS AND METHODS: Both SUG with retrograde saline infusion and retrograde urethrography (RUG) were performed in 5 young normal volunteers and 20 patients with symptoms of impaired urine flow. Those findings were compared with urethroscopic and operative findings in all patients. RESULTS: SUG was more accurate in the evaluation of the stricture length and degree than RUG in 7 patients with anterior urethral strictures, when compared with their subsequent open urethroplasty findings. Only SUG could classify the degree of spongiofibrosis surrounding the strictures in 15 patients. So, SUG was diagnostically as efficacious as or, superior to, RUG in all 20 patients. CONCLUSION: SUG can be used as one of complementary and reliable tools for diagnosis, evaluation and follow-up of anterior urethral strictures.

6.Percutaneous balloon dilatation for transplant ureteral strictures.
Journal of the Korean Radiological Society 1993;29(5):935-943
We report 10 kidney-allografted patients treated for 11 ureteral strictures with standard endourologic ballon catheter dilatation and internal stenting between August 1979. They have been followed until 2 to 140 months (mean 42). We compared and alalyzed the 6 successful strictures(54%) and 5 unsuccessful strictures. There was no statistically significant difference of demographic, clinical and radiologic interventional techniques between two groups. But there was slightly higher success rate in abruptly narrowed shorter fibrotic strictures in ureteroneocystostomy sites than smoothly tapered longer ones in other sites of the ureter. Longterm stenting by the transplantation team with cystoscopic removal of internal ureteral stents by urologists resulted in 3 cases of stent occlusion, encrustation or fracture. Exact early diagnosis of ureteral structure with continued close follow up and proper radiologic interventional procedure with optimal stenting period may increase the success rate and still provide an alternative to surgery.

9.The Craniofacial Structure of Some Korean Adults with Normal Occlusion.
Korean Journal of Physical Anthropology 1994;7(1):9-23
The characteristics of craniofacial complex mere different from each individual, based on age, sex, size, race and environmental factors. This study was undertaken to find out the sexual and racial difference of the craniofacial complex using lateral cephalometrics and previous studies. The material of this study was lateral cephalometric radiograms, obtained from 100 Korean adults (50 males and 50 females) ranged 20 to 27 years old, who have normal occlusion and pleasing profile. The results obtained from this study there as follows : 1. The mean values in the craniofacial complex of some Korean adults pith normal occlusion mere established. 2. The maxillae of female subjects there more protrusive than those of males. 3. In size the craniofacial complex, the male subjects were greater than females. 4. In position of upper and lower incisors, the male subjects there more protrusive than females. 5. In ratios between anterior and posterior facial height, the male subjects mere higher than females. 6. The upper incisors of some Korean adults mere relatively more protrusive than those of the other ethnic groups.

10.Dentofacial Changes in Class I Cases Treated With and Without Extraction.
Korean Journal of Physical Anthropology 1996;9(1):45-54
In order to compare the changes of dentofacial skeleton, teeth and soft tissue profile in Class I malocclusion patients treated with and without extraction, cephalometric radiographs were taken in 22 female patients as extraction group and 23 female as nonextraction group who were treated in the Department of Orthodontics in Chonnam National University Hospital. The results were as follows. 1. At the beginning of treatment, average age was 19.0 years in extraction group and 15.9 years in nonextraction group. Duration of treatment was 2.8 years in extraction group and 1.7 years in nonextraction group. 2. Before treatment, there were significant difference between 2 groups in the amount of protrusion and proclination in upper and lower central incisor and lower lip protrusion. After treatment, these differences were decreased. 3. In comparison before and after treatment in extraction group, upper and lower central incisor protrusion and lower lip protrusion were significantly improved. In nonextraction group, retrusion and improvement of inclination of upper and lower central incisor were not found.
