Purpose: Laparoscopic total gastrectomy (LTG) for gastric cancer is still uncommon because of technical difficulties, especially in esophagojejunostomy (EJ). There are many reports for various laparoscopic procedures of EJ using linear or circular staplers. On the other hands, there has been no report for hand-sewn anastomosis. We report successfully performed intracorporeally hand-sewn EJ after LTG. Materials and Methods: The clinicopathologic data and short-term surgical outcomes of 6 patients who underwent totally laparoscopic total gastrectomy for upper gastric cancer from December 2010 and July 2011 were retrospectively reviewed. Results: The mean age was 66.5 years and mean body mass index (kg/$m^2$) was 24.6. All patients had medical comorbidities. The mean patient ASA score was 2.17. Among the 6 patients, previous abdominal operation was performed for 2 patients and combined operation was performed for 3 patients. The mean blood loss, operation time, and EJ anastomosis time was 130 ml, 379.7 minutes, and 81.5 minutes, respectively. The mean time to first flatus, first oral intake, and postoperative hospital stay was 3.0, 3.0, and 12.5 days, respectively. There was no 30-day mortality case. Postoperative aspiration pneumonia and multiple periventricular lacunar infarctions developed in 1 patient. There were no anastomosis-related complications and other major surgical complications. Conclusions: When the intracorporeal anastomotic technique becomes popular in LTG the intracorporeally hand-sewn EJ may be accepted as one method among the various laparoscopic procedures of EJ.

Surgical procedures for parotidectomy had been developed to gain adequate approach, prevent morbidity of nerve, and give esthetic satisfaction. We performed two cases of parotidectomy through facelift incision. One case was reconstructed with superficial musculoaponeurotic system (SMAS) flap and sternocleidomastoid (SCM) muscle rotated flap at the parotid bed. In second case, same procedures were performed, but collagen membrane was additionally implanted for prevention of Frey's syndrome. After surgery, two cases showed esthetic results without neck scar and hollow defect on parotid bed area.

We report a case of a morbidly obese man with an aortic aneurysm, in whom dental surgery was performed before elective cardiac surgery. His aortic aneurysm required emergency surgery. However, because of his morbid obesity, elective cardiac surgery was planned. Considering the high risk of infective endocarditis, dental surgery was required. Our patient was at a high risk of aortic rupture caused by hypertension and breathing difficulty in the supine position. Dexmedetomidine (DEX) is an anti-anxiety, sedative, and analgesic medicine that can stabilize circulatory dynamics and minimize blood pressure fluctuations. We administered intravenous DEX for sedation of the patient in Fowler's position. In conclusion, our understanding of the risk factors of DEX enabled us to perform safe invasive oral treatment.

Introduction: This study examined the treatment patterns of temporomandibular disorders (TMD) including conservative and surgical procedures. Materials and Methods: Patients with TMD who visited Gangnam Severance Hospital from June 2007 to May 2008 were enrolled in this study. All patients were examined from the orthopantomogram, temporomandibular joint (TMJ) tomography, and a clinical examination. The patients who required a further evaluation were examined by magnetic resonance imaging and/or computed tomography. The treatment patterns were divided into counseling, medication, splint therapy, botulinum toxin injection (BTI) and surgical treatment. Results: Among the 2,464 patients, the average age was 31.8 years (ranging from 6 to 93); 764 (31.0%) were male and 1,700 (69.0%) were female. 2,355 (95.6%) patients were treated with conservative therapy; 1,460 (62.0%) patients were treated with medication, 931 (39.5%) patients were treated with splint, and 46 (2.0%) were treated with BTI. There were 109 (4.4%) patients treated surgically. Eight (0.3%) patients were treated with total temporomandibular joint replacement surgery. Conclusion: Almost all patients with TMD were treated using conservative methods. Those patients who received surgical treatment because of an ineffective response to conservative treatment had definite problems with the internal derangement and/or osteoarthritis or had severe clinical symptoms.

This is to report a case of surgical and orthodontic of posterior scissor bite, deep bite and gummy smile by the segmental osteotomies. The surgical thechnics procedures used are Peterson's mandibular posterior segmental osteotomy, modified $K{\ddot{o}}le$ technic for mandibular anterior segment and Wunderer's maxillary anterior segmental osteotomy. The results are as follows : 1) Peterson's mandibular posterior segmental osteotomy could be achieved by the buccal approach with some difficulties in accessbility. 2) Upper and lower anterior segmental osteotomies were followed separately to correct the deep curve of Spee, deep bite and gummy smile in shortened period. 3) All alveolar segments were immobilized in preplanned position by the prefabricated palatal and lingual resin splint, therefore intermaxillary fixation was not necessary.

Velopharyngeal insufficiency(VPI), characterized by hypernasal resonance and nasal air emission, is a speech disorder that can significantly compromise speech intelligibility. Cleft palate, previously repaired cleft palate and submucous cleft palate are associated with VPI. Less commonly, patients may acquire it after adenoidectomy with or without tonsillectomy or as a result of neuromuscular dysfunction. Comprehensive evaluation by a VPI team includes medical assessment focusing on airway obstructive symptoms, perceptual speech analysis, MRI and instrumental assessment. Options for intervention include speech therapy, intraoral prosthetic devices and surgery. Surgical methods can be categorized as palatal, palatopharyngeal or pharyngeal procedures. Each surgical approach has its strengths and limitations. Oro-maxillofacial surgeons are increasingly involved in the referral, evaluation, and treatment of velopharyngeal function. Therefore, understanding of physiology, anatomic structures, evaluation and treatment protocols in VPI is very important. This article presents protocol for evaluation of velopharyngeal function with a focus on indications for surgical interventions.

Obstructive sleep apnea syndrome(OSAS) is a complex sleep disorder characterized by intermittent apnea secondary to sleep-induced obstruction of the upper airway. It occurs because of an airway obstruction anywhere between the trachea and the oronasal apparatus. The hallmark of OSAS is snoring, which is caused by vibration of the tissues of the pharynx as the airway narrows. The consequences of OSAS have focused on excessive daytime sleepiness resulting from sleep fragmentation and the cardiovascular derangements producing hypertension and arrhythmias. The primary method of controlling OSAS has been surgery. The current surgical procedures used for OSAS are tracheostomy, tonsillectomy, nasal septoplasty, uvulopalatopharyngoplasty, anterior mandibular osteotomy with hyoid myotomy and suspension, and maxillary, mandibular and hyoid advancement. We report a case of OSAS that was improved by genial advancement with infrahyoid myotomy and suspension. The patient was objectively documented by polysomnography, cephalometric analysis, and physical examination before the surgical procedure. The patient underwent genial advancement with infrahyoid myotomy and suspension. Patient had a good response from surgery.

Introduction: Surgical extraction of third molar is one of the most frequently performed procedures in oral and maxillofacial surgery unit as the impacted wisdom teeth could cause various complications. Even though, however, extraction of the impacted wisdom teeth is an obligation for the reason of possible complication even for general practitioners, it has been avoided. Various factors concerning surgical extraction of impacted third molar are considered: general condition of patients, relationship with relative anatomies, aspects of impaction, surgeon's skill. Materials and Methods: The consideration and crossing analysis of these factors with 2,463 patients who visit Dankook University dental hospital to extract those impacted third molar. Results: 1. Gender doesn't affect. 2. Medical problems have more complications. 3. There are more complications in high difficulty index (DI) impacted teeth. 4. When inferior alveolar canal overlap mandibular third molar, complication rate is 26.92%. 5. The most common complication was swelling and pain. 6. There is no statistical difference between the incidence of complication and surgeon's experience. Conclusion: In regard to these results, it seems that clinical or radiological examination can predict potential complications of wisdom teeth, and it is helpful to bear in mind the fact.

The most critical factor in determining which type of implant to be used would be the available bone of the patient. Usually a minimum of 5mm in the bone width and 8mm in the bone height is necessary to ensure primary implant stability and maintain the integrity of bone contact surface. Placement of implant is limited by the several anatomic strutures such as maxillary sinus, floor of the nose, inferior alveolar neurovascular bundle and nasopalatine foramen, etc. When severe resorption of alveolar ridge is encountered, implant placement would be a problematic procedure. A number of techniques to improve the poor anatomic situations have been proposed. This article reports 4 cases of patients using surgical procedures such as blade implant technique, cortical split technique in the anterior maxillary area, sinus lifting and lateral repositioning of inferior alveolar nerve, We treated dental implant candidates with unfavorable alveolar ridge utilizing various surgical techniques, resulted in successful rehabilitation of edentulous ridge.
