ABSTRACT
Background@#Endoscope-assisted surgery is a surgical method that has been used in oral and maxillofacial surgical fields. It provides good illumination, clear, and magnified visualization of the operative field. The purpose of this article is to describe the early clinical experiences to conduct minimally invasive surgery with endoscope-assisted enucleation of cysts on the jaw. It appears that this approach may be a superior alternative to the conventional approach. @*Methods@#In this study, 24 patients (9 females, 15 males, average age 41.5) underwent endoscope-assisted cyst enucleation under general anesthesia. All operations were done by one surgeon. The cases were classified depending on whether bone penetration occurred at the cyst site. The cystic lesions were enucleated using an endoscope with a 0°, 1.9 mm diameter, or a 30°, 2.7 mm diameter. Two bony windows were used for the insertion of a syringe for irrigation, curettes, suction tips, sinus blades, surgical drills, and an endoscope. An additional small channel was made for the insertion of endoscopic instruments. @*Results@#The 24 patients who underwent cyst enucleation were regularly observed for 3 to 12 months to evaluate for complications. Although some patients experienced swelling and numbness, these symptoms did not persist, and the patients soon returned to normal and there was no sign of recurrence. @*Conclusions@#The results of this study have suggested the possibility of minimally invasive surgery with endoscopes when it comes to cyst removal in the oral and maxillofacial region. Nevertheless, this study has limitations designed as a preliminary report focusing on the feasibility of endoscope-assisted cyst enucleation in the oral and maxillofacial regions.
ABSTRACT
BACKGROUND@#Brain abscess is a life-threatening condition that occurs due to complications during a neurosurgical procedure, direct cranial trauma, or the presence of local or distal infection. Infection in the oral cavity can also be considered a source of brain abscess.CASE PRESENTATION: A 45-year-old male patient was transported with brain abscess in the subcortical white matter. Navigation-guided abscess aspiration and drainage was performed in the right mid-frontal lobe, but the symptoms continued to worsen after the procedure. A panoramic radiograph showed alveolar bone resorption around the maxillary molars. The compromised maxillary molars were extracted under local anesthesia, and antibiotics were applied based on findings from bacterial culture. A brain MRI confirmed that the three brain abscesses in the frontal lobe were reduced in size, and the patient's symptoms began to improve after the extractions.@*CONCLUSION@#This is a rare case report about multiple uncontrolled brain abscesses treated by removal of infection through the extraction of maxillary molars with odontogenic infection. Untreated odontogenic infection can also be considered a cause of brain abscess. Therefore, it is necessary to recognize the possibility that untreated odontogenic infection can lead to serious systemic inflammatory diseases such as brain abscess. Through a multidisciplinary approach to diagnosis and treatment, physicians should be encouraged to consider odontogenic infections as a potential cause of brain abscesses.
ABSTRACT
PURPOSE: To determine the incidence of asymptomatic bacteriuria in Korean preschool children, we performed national survey. MATERIALS AND METHODS: We surveyed kindergardens in seven representative cities of Korea. Before performing urine culture, we selected children by urine dipstick screening method(leukocyte esterase and nitrite test). And we analysed the incidence according to sex, age and socioeconomic status. RESULTS: Total registered population was 2,239 children and male to female ratio was 1.16. Overall, asymptomatic bacteriuria was found in 1.03%(23 children). In the male the incidence was 0.3%(3 children) and in the female it was 2.0%(19 children). Less than 4 years old children showed higher incidence (2.9%) than those of any other age groups, such as, 0.5% in 4, 1.1% in 5 and 1.3% in 6 years old. High, middle and low socioeconomic status groups showed the incidence as 0%, 0.9% and 1.4%, respectively The number of leukocyte esterase positive children was 184(8.2%) and that of nitrite positive children was 115(5.1%). Among them urine culture was performed in 175children and 23 children showed significant bacteriuria(colony count> 100,000/ml), so predictability of asymptomatic bacteriuria by dipstick test was 13.1% Radiologic study was performed in 9 children who had bacteriuria, but none of them showed urological abnormalities. CONCLUSIONS: From the above data, we found that asymptomatic bacteriuria is more common in female, younger age and lower socioeconomic status among the Korean preschool children. Considering cost-benefit aspects of the screening for asymptomatic bacteriuria, however, we should re-evaluate the necessity of our study on these particular age groups.
