1. Objective. The aim of this study was to investigate whether dental implant exposure to the maxillary sinus cavity increases the risk of maxillary sinus complications. 2. Study design. An implant was placed bilaterally in the maxillary sinus of eight adult female mongrel dogs in a way that it penetrated the bone and mucous membrane of the maxillary sinus floor to the extent of 2 mm, 4 mm, or 8 mm. The implants were left in place for six months. 3. Results. Radiographic and histologic examinations did not show any signs of pathologic findings in the maxillary sinus of the eight dogs. 4. Conclusion. This study indicates that implant protrusion into the maxillary sinus cavity is not related to the development of sinus complications.

In the presence of acute pericoronitis of mandilbular third molar, antibiotic therapy and early incision and drainage are the method of choice, followed by definitive surgical extraction of the tooth as soon as it becomes subacute. If excision of the overlying tissues is decided on, it should be done adequately. All overlying tissues must be throughly excised, and the crown portion of the unerupted tooth should be completely exposed. After excision has been completed, the wound should be managed with a surgical dressing. This should be allowed to remain approximately 7 days. And then, surgical extraction of the impacted mandibular third molar can be done usually. In this operation, there are many complications, such as, postoperative bleeding, infection, trismus, dysphasia and paresthesia. The surgeon are discredited and medicolegal problem may be occurred in the presence of many distressed complications. Therefore, the relatively nonsurgical treatment is the method of choice. So, authors selected the conservative treatment methods of incision and drainage, primary endodontic drainage, operculectomy without surgical extraction of the mandibular third molars. The results were more favorable without the postoperative complication in Wonju old offender prison.

Purpose: The purpose of this study is to compare the dosimetry of electron beam (EB) plans and three-dimensional helical tomotherapy (3DHT) plans for the patients with left-sided breast cancer, who underwent breast conserving surgery. Materials and Methods: We selected total of 15 patients based on the location of tumor, as following subsite: subareolar, upper outer, upper inner, lower lateral, and lower medial quadrants. The clinical target volume (CTV) was defined as the area of architectural distortion surrounded by surgical clip plus 1 cm margin. The conformity index (CI), homogeneity index (HI), quality of coverage (QC) and dose-volume parameters for the CTV, and organ at risk (OAR) were calculated. The following treatment techniques were assessed: single conformal EB plans; 3DHT plans with directional block of left anterior descending artery (LAD); and 3DHT plans with complete block of LAD. Results: 3DHT plans, regardless of type of LAD block, showed significantly better CI, HI, and QC for the CTVs, compared with the EB plans. However, 3DHT plans showed increase in the $V_{1Gy}$ at skin, left lung, and left breast. In terms of LAD, 3DHT plans with complete block of LAD showed extremely low dose, while dose increase in other OARs were observed, when compared with other plans. EB plans showed the worst conformity at upper outer quadrants of tumor bed site. Conclusion: 3DHT plans offer more favorable dose distributions to LAD, as well as improved target coverage in comparison with EB plans.

The management of teeth in the line of a mandibular fracture is controversial despite the general agreement that most of these teeth can be preserved. Teeth should be retained if bony attachments are adequate for survival, the tooth is sound and important in maintaining fixation of the fractured segment of bone. Teeth should be removed if they are loose and interfere with the reduction of fragments, are devitalized and potentially a source of wound infection, are damaged beyond their usefulness or may become devital and interfere with healing by becoming infected. However, tooth removal will increase the level of trauma, extend the severity of the wound and require expensive prosthetic treatment. Therefore, it is very important to conserve infected teeth in the line of a mandibular fracture through early primary endodontic treatment (pulp extirpation, canal enlargement and canal opening drainage) and splinting. The basic principles underlying the treatment of pulpless teeth are those underlying general surgery. Therefore, debridement of the infected wound (pulp extirpation and canal enlargement), drainage (canal opening) and gentle treatment of the tissues (occlusal reduction and teeth splinting) are the principles of surgery. This is a representative case report of conservative care by the early endodontic drainage of infected teeth in the line of a mandibular fracture.

The surgical treatment of extensive urethral strictures remains a controversial topic; although techniques have evolved, there is still no definite method of choice. Since 1968, when Orandi presented an original technique for one-stage urethroplasty using a penile skin flap, the Orandi technique has become the most prevalently used one-stage procedure for anterior urethral strictures. We present a 20-year follow-up experience with one-stage reconstruction of long urethral strictures using a longitudinal ventral tubed flap of penile skin, with some important technical changes to Orandi's original technique to overcome the deficient vascularity caused by periurethral scar tissue. In 1997, a 55-year-old male patient complained of severe voiding difficulty and a weak urinary stream because of transurethral resection of the prostate due to benign prostatic hyperplasia. Another 47-year-old male patient had the same problem due to self-removal of a Foley catheter in 2002. In both patients, a urethrogram demonstrated extensive strictures involving the long segment of the anterior urethra. A rectangular skin flap on the ventral surface of the penis was used considering the appropriate length, diameter, and depth of the neourethra. The modified Orandi flap provided a pedicled strip of penile skin measuring an average of 8 cm. The mean duration of follow-up was 20.5 years. A long-term evaluation revealed stable performance characteristics without any complications.

Generalized anaphylaxis is a most dramatic and acutely life-threatening allergic reaction and may cause death within a few minutes. Differential diagnosis of anaphylaxis is made by clinical signs, such as, mental change, respiratory distress, hypotension, hypoglycemia, urticaria and angioedema. Especially, insulin reaction, myocardial infarction and vasovagal syncope are considered as differential diagnosis. In cases of fatal anaphylaxis, respiratory and cardiovascular disturbances predominate and are evident early in the reaction. This is a case report of the intensive care of anaphylactic shock after intravenous injection of the penicillin in a old medically compromised patient with the maxillary osteonecrosis. The anaphylactic shock symptoms, such as, unconsciousness, respiratory disorder, no pulsation on carotid artery and cardiopulmonary arrest are occurred in intravenous injection of augmentin 1.2 g after the skin test. In spite of immediate emergency cares, such as intravenous injection of epinephrine, endotracheal intubation, cardiopulmonary resuscitation, and continuous intensive care, the patient is expired in 58 hours after anaphylactic shock attack.

Objective : Chronic subdural hematoma (CSDH) is one of the most common intracranial hemorrhages. It can be managed with a simple surgical treatment such as burr-hole trephination and drainage. However, it has a relatively high recurrence rate. The mechanisms and risk factors for the recurrence have not yet been clearly identified and studies have reported varying results. Methods : We analyzed 230 patients with CSDH who were treated with burr-hole trephination and drainage at our institution from March 2011 to March 2016. The patients were divided into recurrence and non-recurrence groups and the medical records of each group were used to analyze the risk factors associated with CSDH recurrence. Results : After burr-hole trephination and drainage, CSDH recurrence was observed in 49 (21.3%) of the 230 patients. In univariate analysis, none of the factors showed statistical significance with respect to CSDH recurrence. In multivariate analysis, preoperative antithrombotic medication was the only independent risk factor for CSDH recurrence (odds ratio, 2.407; 95% confidence interval, 1.047-5.531). Conclusion : The present study found that preoperative antithrombotic medication was independently associated with CSDH recurrence.
