Background: Conservative treatment is performed for isolated anterior wall of the maxillary sinus fractures, in many cases when the fracture is clinically not severe and asymptomatic. Despite the absence of symptoms, complications such as sinusitis, rhinitis, and chronic purulent secretion may develop; therefore, successful reduction is required. We attempted to reduce the risk of complications using an alternative technique: reduction of the fracture with two urinary balloon catheters inserted through the maxillary ostium and fixation using fibrin glue, which minimizes the damage to the bony fragments and sinus mucosa. Methods: In this study, 38 patients who were diagnosed with an isolated anterior wall of the maxillary sinus fracture at our hospital between January 2014 and January 2017 were enrolled. The fracture site was exposed via the Caldwell-Luc approach followed by reduction through the insertion of two urinary balloon catheters using a nasal endoscope and fixation with fibrin glue. The sex, cause of fracture, physical examination, and presence of complications were examined and patient's medical records and facial bone computed tomography scans were analyzed. Results: Radiological evaluation showed that there was no evidence of collapsed reduction fragments. Although some patients had remaining symptoms of hypoesthesia (15%; 3 patients), there were no complications such as infection, rhinitis, sinusitis, and chronic purulent secretion at the surgical site. Conclusion: In this study, we present an alternative surgical technique using two urinary balloon catheters and fibrin glue for the successful reconstruction of an isolated anterior wall of the maxillary sinus fracture. This technique enables precise restoration with a reduced risk of complications.

Purpose: The aim of this study is to evaluate the feasibility and safety of cardia preserving proximal gastrectomy, in early gastric cancer of the upper third. Materials and Methods: A total of 10 patients were diagnosed with early gastric cancer of the upper third through endoscopic biopsy. The operation time, length of resection free margin, number of resected lymph nodes and postoperative complications, gastrointestinal symptoms, nutritional status, anastomotic stricture, and recurrence were examined. Results: There were 5 males and 5 females. The mean age was $56.5{\pm}0.5$ years. The mean operation time was $188.5{\pm}0.5$ minutes (laparoscopic operation was 270 minutes). Nine patients were T1 stage (T2 : 1), and N stage was all N0. The mean number of resected lymph nodes was $25.2{\pm}0.5$. The length of proximal resection free margin was $3.1{\pm}0.1$ cm and distal was $3.7{\pm}0.1$ cm. Early complications were surgical site infection (1), bleeding (1), and gastro-esophageal reflux disease (1) (this symptom was improved with medication). Late complications were dyspepsia (3) (this symptom was improved without any treatment), and others were nonspecific results of endoscopy or symptom. Conclusions: Cardia preserving proximal gastrectomy was feasible for early gastric cancer of the upper third. Further evaluation and prospective research will be required.

Peri-apical implant lesion, also known as 'retrograde peri-implantitis' can occur with multifactorial etiological factors. The purpose of this case report is to demonstrate resolution of periapical implant lesion by removal of causative factors and saving implant by regenerative therapy. A 54-year old male patient with mild dull pain around implant on the right mandibular second premolar area due to persistent peri-apical infection of the adjacent first premolar was treated. Extraction of tooth with symptomatic apical periodontitis and regenerative therapy on the buccal fenestration area of the implant and extraction site were performed. After 6-month reentry, notable regenerated bone tissue around implant was found, and implant placement on the previous extraction site was performed. After 14-month follow-up from the regenerative therapy, neither biological nor mechanical complication could be found around the implant, evidenced by high implant stability, normal clinical probing depth, and absence of discomfort spontaneously and during masticatory function. In conclusion, surgical intervention including regenerative therapy using bone graft and barrier membrane on periapical implant lesion can be suggested as one of the treatment options considering the extent of periapical lesion.

The reconstruction of deep soft tissue defect such as pressure sore has difficult problems. Myocutaneous flaps have been used commonly as the best coverage method for pressure sore. But, they have several drawbacks such as sacrifice of functional muscle, high morbidity of the donor sites and bulkiness at the recipient site. The concepts of perforator flap has recently developed and widely used to overcome these disadvantages. Between March 2005 to July 2006, we have treated 9 patients who had pressure sore using perforator based fasciocutaneous island rotation flap. Preoperative unidirectional Doppler was used in all cases. Mean number of perforator vessels was 3.8 and flap sizes were from $7{\times}5\;cm$ to $14{\times}13\;cm$. Rotation angles of flap were from 90 degree to 180 degree. In all cases, donor sites were closed primarily. All flap survived completely and postoperative complications were wound dehiscence in 1 case, wound infection in 3 cases. The mean postoperative follow up period was 15.7 months and recurrence was not reported. We could decrease donor site morbidity and cover wound sites easily by using flap rotation and get robust blood supply without sacrifice of functional muscle. Fasciocutaneous perforator island rotation flap would be very useful for various pressure sore treatment.

Maxillary defect may be induced by trauma, inflammation, cyst, tumor and surgical procedure. In case of limited wall defect, free bone graft has been preferred. But it has some problems such as postoperative bone resorption and soft tissue inclusion to recipient site. And we can not use free bone in the case who has inflammation in the donor site. So we used the micro-titanium mesh as reconstructive material for the maxillary wall defect. We had operated 8 patients who were diagnosed as maxillary partial defects from June 1997 to September 1998 in the Chin-Hae military hospital. They were 1 case of antral wall defect, 1 case of palatal wall defect, 5 cases of infra-orbital wall defects and 1 case of oroantral fistula case. As a result, the micro-titanium mesh has shown the morphological stability and biocompatibility and it could be used in case who has infection. And mesh structure could prevent soft tissue ingrowth to bony defect area. Thus it can be used to the case of maxillary partial defect successfully.

The pedicled omental flap has been used for treatment of various kind of complications in thoraxcic surgery. Its property of promoting neovascularization , immunilogic properties that limiting the spread of infection, providing soft tissue coverage are very effective in treatment esophageal fistulas. Also, congenital broncho-esophageal fistula [ BEF ] is a rare disease entity which was reported about 100 cases around the world. We experienced 27 years old female patient with Braimbridge type I congenital BEF. We performed division of BEF using stapler and pericardial patch coverage of esophageal side with concomittent left lower lobectomy. This patient was complicated with postoperative esophageal leakage with empyema thoracis. We have successfully managed these problems with re-thoracotomy and re-closure of esophageal fistula using Right Gastroepiploic Artery based pedicled omental flap wrapping around the esophageal anastomosis site. It is felt that pedicled omental flap is a very effective method to manage esophageal complication such as postoperative esophageal leakage.

Some types of spinal dysraphism can be accompanied by extraspinal cysts, including myelomeningocele, myelocystocele, myelocele, meningocele, limited dorsal myeloschisis, lipomyelomeningocele, and terminal myelocystocele. Each disease is classified according to the developmental mechanism, embryologic process, site of occurrence, or internal structure of the extraspinal cyst. In most cystic spinal dysraphisms except meningocele, part of the spinal cord is attached to the cyst dome. Most open spinal dysraphisms pose a risk of infection and require urgent surgical intervention, but when the cyst is accompanied by closed spinal dysraphism, the timing of surgery may vary. However, if the extraspinal cyst grows, it aggravates tethering by pulling the tip of the cord, which is attached to the dome of the cyst. This causes neurological deficits, so urgent surgery is required to release the tethered cord.

A perianal tick and the surrounding skin were surgically excised from a 73-year-old man residing in a southwestern costal area of the Korean Peninsula. Microscopically a deep penetrating lesion was formed beneath the attachment site. Dense and mixed inflammatory cell infiltrations occurred in the dermis and subcutaneous tissues around the feeding lesion. Amorphous eosinophilic cement was abundant in the center of the lesion. The tick had Y-shaped anal groove, long mouthparts, ornate scutum, comma-shaped spiracular plate, distinct eyes, and fastoons. It was morphologically identified as a fully engorged female Amblyomma testudinarium. This is the third human case of Amblyomma tick infection in Korea.

Abscesses are common in the oral and maxillofacial area. However, secondary thrombosis of the internal jugular vein accompanying the primary abscess is rare. In 1936, Andre Lemeierre studied 20 patients who showed an initial oropharyngeal infection, septicemia, internal jugular vein thrombosis, and secondary spread of the infection, and after then this condition Lemierre syndrome. Clinically, these patients present with tonsilitis lasting several days, continuous fever, and cervical pain. In the past, ligation and excision of the internal jugular vein was often performed. Current therapeutic modality for this condition is appropriate antibiotic prescription and surgical drainage of abscess. This case report presents a patient who showed symptoms of Lemierre syndrome, initiated as an oropharyngeal infection then developed thrombosis of the internal jugular vein. This patient was admitted into Seoul National University Dental Hospital. In addition to routine antibiotic therapy, surgical incision and drainage of the infection site was performed. Without ligation or excision, the thrombosed IJV disappeared eventually. As the Lemierre syndrome is not a common disease, this case report and review of the literature would be useful regarding a treatment of patients with Lemierre syndrome.
