The dentigerous cysts originate through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium, or between this epithelium and the tooth crown. Next to the radicular cyst, they are the second most common type of odontogenic cyst. They occur over a wide age range with a peak frequency in the 2nd to 3rd decade. A substantial majority involve the mandibular third molars, followed in order of frequency by the maxillary permanent canines, mandibular second premolars, and maxillary third molars. With regard to the treatment of these cysts, the marsupialization procedure with obturator is recommended during the age when the eruptive force of the teeth is still strong. It can be effective when preservation of the displaced teeth is desirable. We treated the dentigerous cyst by marsupialization with obturator and guided the eruption of involved teeth to normal position. And we got the results as follows : 1. Severely dislocated teeth associated with dentigerous cyst erupted into proper position. 2. The enamel hypoplasia and the root deformity were observed some cases. 3. The bone expansion and defect were healed without infection and recurrence.

Purpose: We wanted to evaluate the results of arthroscopic management of an isolated rupture of the subscapularis tendon using suture anchors. Materials and Methods: Twenty nine patients with unilateral ruptures of the subscapularis tendon and who underwent arthroscopic repair between February 2001 and October 2007 were reviewed prospectively. All the cases were isolated tears of the subscapularis without the involvement of any other rotator cuff tendon. In 19 patients the tear was localized to the superior one third, in 7 cases the tear was localized to the upper two thirds and the entire tendon was involved in 3 cases. The mean follow up period was 12.2 months (range: 6-26 months). The results of the treatment were assessed by evaluating the constant shoulder score and the pain score before surgery and after surgery. Results: The constant shoulder score improved from $49.9\pm7.3$ to $73.8\pm3.0$ points compared to before surgery and the pain score improved from $4.3\pm3.2$ to $11.2\pm3.0$ points postoperatively. Conclusion: Arthroscopic repair of isolated ruptures of the subscapularis tendon using suture anchors is a good option for effectively managing these tears.

Ten cases with esophageal foreign body were treated surgically from July 1980 to October 1995 at the Departme t of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The mean age was 45.3 years, with a range from 25 to 71. Out of ten cases, 6 were female and four were male. Common symptoms were dysphagia, fever, foreign body sensation and neck pain. Three cases of foreign bodies were of fish bones, two of bubble paclcage of drugs, one case of a Eeer bottle cap, one of a piece glass, one of a bathtub plug, one of chicken and one of a bean. The diagnosis was established by esophagography using a water soluble contrast material and esophagoscopy. Among of ten cases, two had esophageal stricture due to the ingestion of Aye at a young age. One case had experienced psychological problems. All foreign bodies were removed by surgical procedures. Five cases were treated by cervical esophagostomy, one case by right thoracotomy, one case by retrograde bougienation through gastrostomy and two cases by cervical incision and drainage for cervical abscess. Three cases developed pos operative esophageal leaks which healed spontaneously and transient hoarseness developed in one case. One case developed traumatic pneumothorax and subcutaneous emphysema which was treated by closed thoracostomy. There were no operative deaths. C(ocean J Thorac Cardiovasc Surg 1997;30:1117-20)

Symptomatic neuromas after amputation can be troublesome to treat and make it difficult to properly fit a brace. Surgical management is required when conservative management such as prosthetic socket modification or local injections fail. However, small cutaneous nerves adhere to adjacent soft tissue and they are difficult to locate. The authors suggest that ultrasonography guided tattoo localization using a charcoal suspension is useful to find a visually indistinguishable neuroma.

Radicular cyst is a true epithelium lined cyst formed when epithelium at the apex of a nonvital tooth is stimulated by inflammation. It is the most common type of cyst in the oral cavity, but its frequency is low in the primary dentition. Treatment of large-sized cyst aims at conservation of adjacent structure and allowance of proper eruption of the successive permanent teeth in the primary dentition. Considering these two aspects, marsupialization or enucleation following decompression is recommended as a treatment means for large-sized radicular cyst. In this case, 8-year old boy visited the pediatric dentistry department. Yonsei University Dental Hospital, with the chief complaint of pain on the lower right area. Clinical and radiographic examinations revealed periapical radiolucent lesion on #84, which had previous pulp treatment and restorated with the stainless steel crown. Dislocation of its successive tooth, #44, was also observed. #84 was extracted and sent for biopsy. Through histologic examination, it was diagnosed as radicular cyst. Following its extraction, removable space maintainer was delivered, which was also used as a decompressor. During periodic check-up for next 22 months, favorable healing of the lesion and eruption of the successive tooth were observed.

The Dentigerous cyst is reported to be one of the most common lesions of the jaw. It is derived from reduced enamel epithelium that surrounds the crown of an unerupted tooth. Dentigerous cysts usually remains asymptomatic and presents as well-circumscribed radiolucencies surrounding the crown of a tooth. Most dentigerous cysts are treated by surgical enucleation or marsupialization of the cyst to allow eruption of the permanent tooth. The nasopalatine duct cysts derived from the islands of epithelium remaining after closure of the embryonic nasopalatine duct. The cyst presents as a well-circumscribed oval or heart-shaped radiolucency located in the midline of the anterior maxilla between the roots of the central incisors. Treatment is by surgical enucleation, employing a palatal approach. This report present two cases. One case was diagnosed with dentigerous cyst and treated by enucleation. 12 Months later, affected second premolar was erupted normally. The other case was diagnosed with nasopalation duct cyst. Histological examination of the enucleated cyst confirmed a nasopalatine duct cyst. There was no recurrence during follow up period.

Background: Sternal wound infection (SWI) is an important complication after cardiac surgery. The aim of this study was to investigate the predictors affecting sternal wound infection and preventive factors including short term Vancomycin therapy in patients who underwent coronary artery bypass grafting (CABG). Material and Method: A retrospective study was done using data collected from January 2001 through December 2007. This included 219 patients who had isolated CABG. The definition of SWI was documentation from a microbiological study and a requirement for simple closure or other surgical revision. Result: The overall incidence of SWI was 7.8% (n=17). The causative organisms were methicillin resistant Staphylococcus aureus (MRSA, n=13), methicillin resistant Staphylococcus epidermidis (n=2), Pseudomonas aeruginosa (n=1), and Candida albicans (n=1). Ten cases had deep sternal wound infection with mediastinitis; 7 cases had a superficial wound infection. Infection-related mortality was low (1/17; 6%). Diabetes mellitus (p=0.006) and smoking history (p=0.020) were factors that predicted high risk. Short term use of vancomycin decreased the incidence of MRSA-associated SWI (p=0.009). For treatment, curettage and rewiring or flap were needed in most cases (88%, n=14). Conclusion: Patients who had diabetes mellitus and a smoking history need careful management. Short term use of vancomycin is effective for prevention of SWI with MRSA.

Purpose: After periodontal surgery, studies have found that the use of periodontal wound dressing reduces the risk of wound infection and increases healing. The purpose of this study is to evaluate the effect of attachable periodontal wound dressing on the healing and patient satisfaction after periodontal flap surgery. Materials and Methods: Twenty-eight patients requiring periodontal surgery underwent periodontal flap surgery on both quadrants of maxilla or mandible. Postoperative pain, bleeding, dietary discomfort and hypersensitivity in relation to attachable periodontal wound dressing was assessed using Visual Analogue Scale (VAS). Additional survey on frequency of burning sensation and overall satisfaction rates were assessed. Results: VAS mean values for pain, bleeding, and dietary discomfort depending on the presence and absence of attachable wound dressing were; pain: 2.82, 3.96 (P = 0.002), bleeding: 1.61, 2.54 (P = 0.008), dietary discomfort: 2.82, 4.18 (P < 0.001), respectively. Test groups with attachable wound dressing reported significantly lower rates of discomfort. No significant difference was observed in burning sensation and hypersensitivity related with wound dressing. Satisfaction was higher in 75% of patients who received wound dressing. Conclusion: According to the results of this study, patients who received attachable periodontal wound dressing reported less postoperative pain, bleeding, and dietary discomfort. There was no statistical significance related to the use of wound dressing with burning sensation and hypersensitivity.

A 12-year-old castrated male Shih-tzu dog presented with vomiting, anorexia, and weight loss. The patient's medical history and hematological, radiographic, ultrasonographic, and endoscopic findings were used for diagnosis. The patient's medical history showed that he was being treated for chronic kidney disease since a few weeks. The serum biochemical analysis showed moderate azotemia. However, abdominal radiographic and ultrasonographic findings showed the presence of a mass in the pylorus area of the stomach. On gastrointestinal endoscopic examination, the proliferative mass was found in the pyloric antrum. The histopathological results of the endoscopic biopsy specimen indicated that it was strongly suspected a gastric adenoma; therefore, we surgically excised the pyloric outflow region via a Y-U pyloroplasty. The histopathological examination of the surgically excised specimen also indicated that the mass was a gastric adenoma. After surgical treatment, the patient's condition improved gradually, and the clinical symptoms diminished in approximately 3 weeks after surgery. The patient's condition was well controlled until recently, i.e., 18 months after surgery. This case report describes the clinical findings, imaging characteristics, endoscopic findings, and histopathological features of a gastric adenoma in the pyloric outflow tract of a dog.

Traumatic bone cyst (TBC) is an asymptomatic lesion seen most in adolescents. TBC is found incidentally on routine panoramic examinations and appears as a relatively well-demarcated unilocular radiolucency with scalloped margins. Histological examination reveals a vacant cavity of cancellous bone usually unlined or very occasionally lined with a thin connective tissue layer. The lack of lining epithelial membrane is common histological feature. The most affected site is between the mandibular canine and third molar. The involvement of the mandibular symphysis is rare. The etiopathogenesis of the TBC is unclear. TBC is treated with surgical exploration and curettage; new bone is formed in place of the lesion within 6 - 12 months of surgery. Diagnosis of TBC prior to surgical intervention has limitations in most of the cases. Both of our patients were diagnosed through radiological examination and biopsy. Neither patient had a history of trauma. After surgery, the panoramic radiograph and CBCT were used to confirm bone healing.
