Descending Necrotizing Mediastinitis (DNM) is a complication of oropharyngeal infections that can spread to the mediastinum. It is difficult to diagnose early because clinical and radiologic findings appear in the late stage of the infection. late diagnosis is the principal reason for the high mortality in DNM. An 18-year-old female admitted with Ludwig's angina from dental caries. Despite of combined antibiotics, dental extraction and drainge of submental abscess, infection spread to the cervical area. Chest computed tomogram revealed extension of the abscess to the pretracheal and periaortic space and development of bilateral pleural empyema. We performed bilateral cervical mediastinotomy and thoracotomy for drainage and debridement. Tracheostomy to secure the airway and postoperative pleural irrigation were performed. Postoperative course was uneventful and patient was discharged on the 40th postoperative day. It is important to perform chest CT scanning for early diagnosis of DNM when oropharyngeal infection spreads to the cervical area. Improved survival of patients with DNM implies early and radical surgical drainage and debridement via a cervical mediastinomy and thoracotomy.

PURPOSE: The aim of this study is to assess the long-term results of laparoscopic common bile duct exploration (LCBDE) and validate its effectiveness as a primary treatment modality for CBD stone. METHODS: A retrospective review of the medical records of 157 patients who underwent LCBDE from 1997 to 2011 was conducted. All LCBDE were performed by choledochotomy. Clinical demographics, operative outcome, recurrence rate of CBD stones, and long-term bile duct complications were analyzed. The mean follow-up period was 51.9 months. RESULTS: LCBDE was completed in 152 patients (96.8%) and 5 patients (3.2%) had open conversion. The male/female ratio was 78/79 and mean age was 67.3 years. Stone clearance was successful in 149 of 152 patients (98.0%). Nonlethal complications were noted in 11 patients (7.2%), including bile leakage in 6 patients (3.9%). Recurrent CBD stones developed in 9 of 152 patients (5.9%). Preoperative endoscopic sphincterotomy (P = 0.492) and choledochotomy repair type (T-tube drainage vs. primary closure, P = 0.740) were not significantly related to stone recurrence. There were no signs of any type of biliary injury or stricture observed in any of the patients during the follow-up period. CONCLUSION: LCBDE can be performed without increased risk of long-term complications such as bile duct stricture and recurrent CBD stones. LCBDE is a safe and effective treatment option for choledocholithiasis in terms of long-term outcome as well as short-term outcome.

Congenital anomaly of IVC is rare, but understanding of this anomaly is important in radiological diagnosis,angiographic procedures and major retroperitoneal and thoracic surgery. We analysed 23 cases of IVC interruptiondiagnosed by cardiac angiography at Seoul National University Hospital. The results were as follows: 1. Theincidence of infrahepatic interruption of IVC was 0.45% of the patients having cardiac angiography and mostpatients showed cyanosis(91%). 2. The most common associated cardiac anomaly was right ventricular outflow tractobstruction (60%). Other associated cardiac defects were VSD, ASD, valvular anomaliesin 9 cases(39%) respectively;double outlet right bentricle, bilateral superior vena cava, single ventricle in 6 cases(26%) respectively; singleatrim, PDA in 5 cases(22%) respectively. 6 cases of situs inversus, 3 cases of situs ambiguus,2 cases of visceralheterotaxia and one case of asplenia were observed also. 7 cases of left-sided IVC were associated with IVCinterruption in normal situs.

OBJECTIVES: We report a case of Ogilvie's syndrome following posterior decompression surgery in a spinal stenosis patient who presented with acute abdominal distension, nausea, and vomiting.SUMMARY OF LITERATURE REVIEW: Ogilvie's syndrome is a rare and potentially fatal disease that can easily be mistaken for postoperative ileus, and is also known as acute colonic pseudo-obstruction. Early recognition and diagnosis enable treatment prior to bowel perforation and requisite abdominal surgery. MATERIALS AND METHODS: An 82-year-old woman presented with 6 months of worsening back pain with walking intolerance due to weakness in both legs. She had hypertension, asthma, and Cushing syndrome without bowel or bladder symptoms. Further workup demonstrated the presence of central spinal stenosis on magnetic resonance imaging. The patient underwent an L2-3 laminectomy and posterior decompression. Surgery was uneventful. RESULTS: The patient presented with acute abdominal distension, nausea, and vomiting on postoperative day 1. The patient was initially diagnosed with adynamic ileus and treated conservatively with bowel rest, reduction in narcotic dosage, and a regimen of stool softeners, laxatives, and enemas. Despite this treatment, her clinical course failed to improve, and she demonstrated significant colonic distension radiographically. Intravenous neostigmine was administered as a bolus with a rapid and dramatic response. CONCLUSION Ogilvie's syndrome should be included in the differential diagnosis of postoperative ileus in patients developing prolonged unexplained abdominal distension and pain after lumbar spinal surgery. Early diagnosis and initiation of conservative management can prevent major morbidity and mortality due to bowel ischemia and perforation.

Failure of fixed implant supported prosthesis is caused by biomechanical factors such as excessive occlusal stress and biological factors such as bacterial infections andinflammation. Implants with severe bone resorption that have worsened without being resolved due to implant complications should be removed and then new treatmentsshould be planned, taking into account remaining teeth, remaining implants, and residual alveolar. The patient of this case removed some of fixed implant prosthesis of mandible.The condition of the remaining alveolar bone was reassessed for further implant replacement and a few implants were placed. Then implant assisted removable partialdenture (IAPRD) treatment is performed using implant surveyed bridge as abutment. Through this treatment, the clinical results were satisfactory on aspect of masticatoryfunction recovery and oral hygiene management. (J Korean Acad Prosthodont 2020;58:161-8)

Objective: To evaluate the following null hypothesis: the skeletal and dentoalveolar expansion patterns in the coronal and axial planes are not different with two different types of microimplant-assisted rapid palatal expansion (MARPE) systems. Methods: Pretreatment (T0) and post-MARPE (T1) cone-beam computed tomography (CBCT) images of 32 patients (14 males and 18 females; mean age, 19.37) were analyzed. We compared two different MARPE systems. One MARPE system included the maxillary first premolars, maxillary first molars, and four microimplants as anchors (U46 type, n = 16), while the other included only the maxillary first molars and microimplants as anchors (U6 type, n = 16). Results: In the molar region of the U6 and U46 groups, the transverse expansion at the midnasal, basal, alveolar, and dental levels was 2.64, 3.52, 4.46, and 6.32 mm and 2.17, 2.56, 2.73, and 5.71 mm, respectively. A significant difference was observed in the posterior alveolar-level expansion (p = 0.036) and posterior basal-bone-level expansion (p = 0.043) between the groups, with greater posterior skeletal and alveolar expansion in the U6 group. Conclusions Compared with the U46 group, the U6 group showed greater posterior expansion at the alveolar and basal-bone levels, with an almost parallel split. Both groups showed a pyramidal expansion pattern in the coronal view.

Purpose: The aim was to conduct a three-dimensional comparison of impacted canines with their contralateral normal counterparts in patients exhibiting unilateral buccal impaction of the maxillary canine, utilizing the palatal plane as the benchmark reference. Materials and Methods: Computed tomography scans from a cohort of 31 patients diagnosed with unilateral buccal impaction of the maxillary canine were analyzed. The impacted canine was examined against the contralateral normal canine, focusing on the variables of rotation, torque, angulation, root length, and root volume. The disparities in these parameters between the left and right canines and their association with patient age were evaluated. Results: Notable differences were observed in rotation, angulation, torque, root length, and root volume when comparing the impacted canine to its contralateral normal counterpart.Furthermore, a significant positive correlation was identified between the age of the patients and the root length discrepancy of the impacted and contralateral normal canines. Conclusion The palatal plane proves to be a viable skeletal reference for predicting the impaction of maxillary canines, with rotation, angulation, and torque serving as reliable indicators. The study further elucidates that the unilateral buccally impacted maxillary canine is characterized by a discernibly shorter root length and diminished root volume in comparison to the contralateral normal canine.
