ABSTRACT
OBJECTIVES: In the present study, we aimed to develop an oral examination smart chart application for tablet personal computers (PC). We evaluated the time required to perform an oral examination and assessed the degree of user's convenience by using this application. We determined to make our application cost and human resource effective by automatically computerizing the statistics to facilitate its application in oral health services such as national oral health research. The development of this application for tablet PCs was aimed at recording the results of oral examinations. METHODS: We produced flow charts and designed the program screen, which would replace the existing paper chart. To evaluate the efficiency of the application, 1 preventive dentistry professor and 6 dentistry students performed an oral examination on 41 subjects. We performed the oral examination in duplicate using a tablet PC and a paper chart. The data collected were analyzed using the SPSS 18.0 program. P-values less than 0.05 were considered statistically significant. RESULTS: The time required for oral examination by the study group (the group using the application) and the control group (the group using paper) were 131.93+/-10.14 and 151.85+/-7.77, respectively; the difference between these values was statistically significant (P-value=0.002). The oral examination could be performed faster in the study group (the group using the application) than in the control group; therefore, we noted that the time taken for oral examination was reduced by using the application. CONCLUSIONS: The tablet-based system has been shown to save time by omitting the step of entering the paper chart data into a computer. Further, the findings of this study can be used to establish an oral health index database with the help of additional resources. Moreover, it would facilitate creating awareness among the patients with regard to their oral health indices through the use of visual aids.

The term concha bullosa describes aerated turbinate and it is most common on middle turbinate. Symptoms of concha bullosa depends on the amount of pneumatization and location. Concha bullosa without symptoms does not need surgical treatment, however, surgical treatment is indicated when it causes nasal obstruction. There are many reports of concha bullosa because it is a common anatomic variation. Despite many reports of concha bullosa, there is no definite statistics on the size of concha bullosa, and there has been no reports on what its largest size is. This report deals with a giant concha bullosa of middle trubinate of 4.5 cm in length, 2.2 cm in width size causing complete nasal obstruction.

The congenital absence of the major salivary glands is an uncommon disorder, although it is not always symptomatic. Their etiopathogenesis is poorly understood. Aplasia of the salivary glands may occur either in isolation or in association with other developmental abnormalities. Some authors have reported familial salivary gland aplasia. Aplasia may be partial or total. Severely affected patients suffer from dry mouth and an increased rate of dental decay. Following clinical exclusion of the cause of these symptoms, the diagnosis of submandibular gland aplasia can be confirmed by computed tomography and a Tc-99m pertechnate scintiscan. The authors experienced a case of incidentally detected, unilateral submandibular glandular aplasia in a 38-year old female. So we present this case with review of literatures.

BACKGROUND AND OBJECTIVES: The traditional adenoidectomy using adenotome and adenoid curette could not guarantee a clear operative field due to bleeding. Also the traditional transoral adenoidectomy was not always effective in the complete removal of adenoid tissues obstructing the choana and surrounding the eustachian tube. This study was performed to evaluate the effectiveness of using the electric suction coagulator for adenoidectomy. MATERIALS AND METHOD: This study was completed by 60 patients who underwent adenoidectomy or adenoidectomy with ventilation tube insertion. For adenoidectomy, 30 cases were performed using the variable sized suction coagulator via nasal cavity and the other 30 were performed using the adenotome and adenoid curette with oral approach. The amount of intraoperative bleeding and the duration of surgery were recorded. A preoperative and a at least one-month post operative nasal endoscopic photograph and lateral skull radiograph were obtained. RESULTS: Intraoperative bleeding amount was less and less time was needed in suction coagulator method (p<0.05). There was no statistical difference in the postoperative endoscopic grade, adenoid nasopharyngeal ratio, and the shortest nasopharyngeal diameter between two groups. The postoperative improvement of subjective symptoms was not different. CONCLUSION: Adenoidectomy using transnasal suction coagulator is an effective method for complete removal of adenoid with the advantages of excellent visualization and complete hemostasis. Especially, the authors think that this method is useful for the removal of superior part of adenoid and peritubal adenoid tissue.

BACKGROUND: Inguinal herniorrhaphy remains one of the most common general surgical operations. Mesh repair is advocated by several specialized hernia centers. The purpose of this study was to compare results of mesh and Shouldice repair for inguinal herniae. METHODS: A clinical review was made of 73 cases of inguinal herniae treated during the 3 years from January 1993 to December 1996 at the Department of Surgery, Dae Rim Saint Mary's Hospital, and at the Department of Surgery, Eum Sung Saint Mary's Hospital. We treated 38 patients with mesh repair and 35 patients with a Shouldice procedure. Among 73 cases, 72 cases were males and only one case was a female. All except 8 cases had indirect types of hernias. RESULTS: Mesh repair required less time (80 minutes) and was an easier operative technique than the Shouldice procedure (95 minutes), but postoperative pain was similar between the two procedures. Postoperative pain was relieved after one week in 60% of the patients and after four weeks in 88% of the patients. The complications following the operations were similar between the two procedures: voiding difficulties developed in two cases, wound infection in one case, and a hematoma in two cases. There were no recurrences during the 6 month to 3 year follow up. CONCLUSIONS: Inguinal herniorrhaphy using a mesh repair technique provides is simple, rapid, less painful, and effective.

BACKGROUND AND OBJECTIVES: Vestibular compensation is a process of behavioral recovery following unilateral labyrinthectomy (ULX). The neural plasticity in vestibular compensation was assessed by observing changes of behavioral response and c-Fos expression following contralateral labyrinthectomy (second labyrinthectomy) in ULX rats. MATERIAL AND METHODS: Contrala-teral labyrinthectomy was performed 2 weeks after ULX in Sprague-Dawley rats, each weighing 250-300 gm. Changes of spontaneous nystagmus, head tilt, and c-Fos expression in the medial vestibular nucleus (MVN) and nucleus prepositus hypoglossi (PrH) were measured. RESULT: In ULX, spontaneous nystagmus with the slow phase directed to the lesion side was 3.5+/-0.5 beats/sec and head tilt deviated to the lesion side was 71+/-16 degrees just after ULX. Spontaneous nystagmus disappeared within 72 hours, but head tilt was maintained at 28+/-8 degrees until 2 weeks after ULX. The number of c-Fos proteins 2 hours after ULX was 81+/-25 and 212+/-63 in MVN of the lesion side and the intact side, respectively. And PrH showed 136+/-37 in the lesion side and 94+/-19 in the intact side, which was opposite of MVN in spatial expression of c-Fos. In second labyrinthectomy, direction of spontaneous nystagmus and head tilt was opposite to the first ULX and their decrement was faster. c-Fos was expressed more in the MVN of the first labyrinthectomized side than in the second one and PrH showed the opposite pattern to MVN, which was opposite to the first ULX in spatial expression. CONCLUSION: These results suggest that recovery of vestibuloocular reflex in vestibular compensation is accomplished by restoration of neuronal activity in the central nervous system including MVN and PrH.

A clinical analysis was made of 18 cases of traumatic diaphragmatic rupture which had been treated during the 8 years from January 1989 to December 1997 at the Department of Surgery & Chest Surgery, Dae Rim Saint Mary's Hospital. The results are as follows: 1) The most common ages were 3rd and 4th decades (61.1%).There were 14 males and 4 females (M : F = 3.5 : 1) 2) The traumatic diaphragmatic ruptures were due to blunt trauma in 13 (72.2%) patients (left 10, right 3) and penetrating trauma in 5 (27.8%) patients (left 5). 3) The common symptoms were dyspnea (77.8%), abdominal pain (66.7%), and chest pain (55.6%). 4) 12 of the 18 patients were diagnosed before operation. Six patients were diagnosed during operation. 5) 15 of the 18 patients were operated on within 24 hours (83.3%). 6) The most common associated intraabdominal injured organ was spleen (44.4%). The most common herniated organ was colon (27.8%). 7) Most of the injuries ranged in size from 6 to 10 cm in the blunt trauma patients (53.8%) and less than 5 cm in penetrating trauma patients (100%). 8) The operations were done using a laparotomy alone in 11 patients, a thoracotomy in 5 patients, and a thoracoabdominal incision in 2 patients. 9) Postoperative complications were developed in 8 patients (44.4%). 10) The perioperative mortality was 11.1%, and the causes of deaths were hypovolemic shock and septic shock. In conculusion, traumatic diaphragmatic rupture without severe associated organ injury could reveal a good outcome, if early diagnosis and proper treatment was performed.

BACKGROUND: With the advent of functional endoscopic sinus surgery, the importance of the ostiomeatal unit(OMU) has been known. Anatomic abnormalities, irreversible inflammatory changes, or obstruction of ostiomeatal unit lead to sinus ostial obstruction and subsequent chronic or recurrent sinusitis. For these reasons, septal deviation, concha bullosa and paradoxical middile turbinate may compress the uncinate process and occlude the infundibulum and then they may induce anterior paranasal sinusitis. OBJECTIVES: This study was conducted to evaluate the relationship between the existence of anatomical variations of sinonasal regions and Babbel's five patterns of chronic sinusitis based on coronal plane CT and to be helpful in treatment of chronic sinusitis. MATERIALS AND METHOD: From february 1994 to February 1996, Coronal plane CT scans of 150 patients with bilateral sinonasal disease were retrospectively reviewed. We examined anatomical variations-paradoxical middle turbinate, concha bullosa, and septal deviation-using PNS CT and analyzed the finding of PNS CT based on Babbel's five patterns of chronic sinusitis. One patient with bilateral sinonasal disease was considered as two different cases. RESULTS: In consequence of this study, the existence of anatomical variations don't show any influence on the paranasal sinusitis patterns. CONCLUSION: This study suggests that the existence of anatomical variations may not be significantly associated with respective incidence of the paranasal sinusitis patterns and may similarly influence in each patterns of chronic sinusitis.

This study is a clinical review of two groups of patients. Group I was composed of 97 patients who were submitted to negative appendectomy under the impression of acute appendicitis and, group II was 45 patients who received conservative treatment with the same impression at the department of surgery, Dae Rim Saint Mary's Hospital, from January 1, 1994 to August 31, 1996.The purpose of this study is to identify possible factors for the decision of operation or conservative treatment in the patients with suspected appendicitis and so to decrease unnecessary operation. Clinical characteristics of the patients were compared between two groups by the method of comparison of means(X test). The following results were obtained; 1) The incidences of group I and group II among the patients in the state of suspicious appendicitis were 97 of 1,004 cases(9.7%) and 45 of 1,004 cases(4.5%) respectively. 2) The number of female patients was 1.5 times more than male in both groups(p0.05) 8) Leukocytosis above 10,000/mm3 appeared in 44% of patients in group I and 53.3% in group II(p>0.05). 9) In admission route, the patients via ER was 2 times more than those of OPD in group I and in group II that was 5 times more than this.
