1994년 9월 부터 1996년 9월까지 본원에서는 38명의 환자가 비디오 흉강경수술로써 자연성 기흉질환에 대 해 치료를 받았다. 이 중 자연성 기흉 환자는 38명이었으며 남자가 31명 여자가 7명이었고 평균연령은 30세 였다 사망은 없었고 비디오 흉강경을 통한 술후 합병율은 자연성 기흉의 경우에서 7.9%(3/38)였다. 비디오 흉강경을 이용한 자연성 기흉의 수술의 경우에 재발성 기흉은 없었고 창상 열개가 3례, 7일 이상의 지속적 공기 누출이 3례 있었고 동일한 환자였다. 같은 시기에 비디오 흉강경을 이용하여 자연성 기흉을 수술한 38 례의 A군과 개흉술을 이용한 21례의 B군과의 비교 분석을 하였다. A군에서는 평균 추적기간 14.3717.48개 월간 재발성 기흉은 없었으나, B군에서는 16.81$\pm$7.12개월간 1례의 재발이 있었다. 비디오 흉강경 수술과 개 흉술에서의 마취 유도시간을 포함하여 수술시간에는 유의적인 차이는 없었으나 술 후 입원 기간과 술 후 흉관 삽입 기간은 비디오 흉강경 수술시에 보다 적었다. 술 후 합병율은 A군에서 7.9%(3/38)로 B군 42.9%(9/21) 보다 훨씬 적었다. A군에서 동일한 환자에서 창상 열개와 7일 이상의 지속적인 공기누출이 \ulcorner시에 있었던 경우가 3례였고, B군에서는 기흉의 재발 1례와 창상 열개 2례가 동반하는 7일 이상의 지속적인 공기 누출이 8례가 있었고 1례에서는 농흉이 발생하였다. 비디오 흉강경 수술은 개흉술에 비해 자연성 기흉에 대해서 효과적인 치료 방법이다.

Background Repair of facial laceration in the emergency department can pose a number of difficulties. Children can be uncooperative, but adults can also be if they have sustained head trauma or are intoxicated. Leukosan SkinLink consists of topical adhesive and adhesive tape that can be applied easily to long or tense wounds. In this study, the authors compared conventional suturing with Leukosan SkinLink for facial laceration patients in the emergency department. Methods The prospective study was carried out from March 2013 to September 2013 with linear facial laceration patients visiting the emergency department. Exclusion criteria were open fractures, joint injuries, skin defects, hairy skin, and mucosa. The author used Leukosan SkinLink for skin closure in the experimental group and used conventional suturing in the control group. The scar evaluation using the Patient and Observer Scar Assessment Scale (POSAS) along with satisfaction scores, procedure times, and complications were compared. Results A total of 77 patients (30 in the control group and 47 in the experimental group) participated and underwent follow-up for 6 months postoperatively. The scar assessment using the POSAS and the satisfaction score in both groups were similar. The average procedure time in the experimental group was shorter. In the control group, there were four cases of wound dehiscence, two of infection, and one of skin necrosis, whereas four cases of wound dehiscence and one allergic reaction occurred in the experimental group. Conclusions With a simple application technique, Leukosan SkinLink is a new effective method for facial laceration repair especially useful for children and uncooperative adults.

The present study investigates the effects of calcium sulfate graft on the periodontal healing in intrabony periodontal defects of dogs. Following the general anesthesia with 30mg/kg pentobarbital injected intravenously, the first premolar was extracted and full-thickness periodontal flap was elevated from the second premolar to the fourth premolar. The portion of premolars coronal to the alveolar crest was removed and mesial and distal roots were separated. Exposed root canals were sealed with Caviton and covered completely with flaps sutured. Following the healing period of 12 weeks, the surgical sited were uncovered and $4{\times}4mm$ intrabony defects were surgically created. Those defects with calcium sulfate graft following the root planing was designated as the test sites and those with flap surgery-only were designated as control sites. The animals were sacrificed after 8 weeks and the healing was histologically analyzed. The results were as follows. 1. No foreign body reaction or inflammation were observed in either groups. Calcium sulfate was completely resorbed in the test sites. 2. New cementum was observed coronal to the notch in both groups. Connective tissue fibers were oriented parallel to the root surface in the controls. Connective tissues were formed in large amount in the sites. 3. Test sites showed marked amount of new bone formation while the control sites showed minimal bone gain. 4. Root resorption was observed in coronal portions of th control Sites. The results suggest that calcium sulfate is a biocompatible graft material with a potential for new bone and cementum formation.

Purpose: Axillary osmidrosis is caused by excessive apocrine gland secretion, which causes an unpleasant odor. Axillary osmidrosis causes difficulty in social activities and personal handicap. We studied the long term follow up results of our surgical procedures and sought to find a best surgical treatment methods. Methods: From January 1991 to December 2006, a total of 1864 patients(587 men, 1277 women) had been treated with this procedure for axillary osmidrosis and hyperhidrosis. Follow up periods varied from 10 to 15 years. We used the subdermal excision technique, using two small incisions over the axilary folds and using a Kawata dissector(instrumental shaving) and additional manual subdermal excision(manual shaving). Results: Among the total patients, 782 patients were followed up. Except a pure hyperhidrosis patients, 759 osmidrosis patients was included. 588 patients(77.4%) had a good results, 148 patients(19.5%) had a moderate results and 23 patients(3.1%) had a recurrence. Complication developed in 189 patients(10.1%): hematoma or seroma in 25 patients, wound dehiscence in 86 patients, partial skin necrosis in 45 patients, and infection in 28 patients. Conclusion: We conclude that our method has several advantages such as 1) short operation time, 2) minimal scaring, 3) lower complication rates, 4) high satisfactory rates.

Background Various surgical techniques have been used to correct Tessier number 7 craniofacial cleft, which involves macrostomia, ear deformity, and hemifacial microsomia. To achieve symmetrical and satisfactory results in patients with macrostomia, the authors performed a 1-mm medial overcorrection on the cleft side and evaluated the results of this procedure. Methods A retrospective medical record review of patients diagnosed with Tessier number 7 craniofacial cleft from March 1999 to February 2017 was performed. Using clinical photographs, outpatient clinic records, and operative records, information was recorded regarding concurrent congenital anomalies, postoperative complications, and follow-up. Using Photoshop CS2, the length of both sides of the lip was compared. The ratio of these lengths was calculated to evaluate lip symmetry. Results Of the patients treated at the Department of Plastic and Reconstructive Surgery at Kyungpook National University Chilgok Hospital, 11 (male-to-female sex ratio, 7:4) were diagnosed with Tessier number 7 craniofacial cleft. Concurrent congenital anomalies included skin tag, hemifacial microsomia, and cleft palate. The mean duration of follow-up was $78.273{\pm}72.219$ months and the mean ratio of the lengths of both sides of the lip was $1.048{\pm}0.071$. Scar widening occurred as a postoperative complication in some patients. No cases of wound infection, bleeding, or wound dehiscence occurred. Conclusions For the successful correction of macrostomia, plastic surgeons should consider both functional and aesthetic problems of the lip. Adequate repair of the orbicularis oris muscle, skin closure with Z-plasty, and medial overcorrection of the neo-oral commissure led to good results in our patients.

Elevating thin flaps has long been a goal of reconstructive surgeons. Thin flaps have numerous advantages in reconstruction. In this study, we present a surgical method for elevating a thin flap and demonstrate the safety of the procedure. A retrospective review was performed of the electronic medical records of patients who underwent thin flap elevation for lower extremity reconstruction from April 2016 to September 2016 at the Department of Plastic Surgery of Asan Medical Center. All flaps included in this study were elevated above the superficial fascia. A total of 15 superficial circumflex iliac artery free flaps and 13 anterolateral thigh free flaps were enrolled in the study. The total complication rate was 17.56% (n=5), with total loss of the flap in one patient (3.57%) and partial necrosis of the flap in four patients (14.28%). No wound dehiscence or graft loss at the donor wound took place. Elevation above the superficial fascia is not inferior in terms of flap necrosis risk and is superior for reducing donor site morbidity. In addition to its safety, it yields good aesthetic results.

The superiorly based flap tracheostomy(SBFT) has been advocated as an new technique of tracheostomy to manage a wide variety of causes of upper airway obstruction. This technique has particular applicability in patients who require long term tracheostomy such as in bilateral vocal cord paralysis and severe obstructive sleep apnea. SBFT has numerous advantages such as shortening of the gap between the skin and trachea : construction of a self-sustaining tract ; circumferential mucocutaneous junction to reduce infection, granulation tissue, bleeding, and stenosis of the tract : avoidance of the laryngotracheal damage : easy placement of a tracheostomal stent to promote speech, coughing and swallowing. Most of all, this technique can reduces the suprastomal buckling by the support of the superiorly based tracheal flap, and thus prevents the stenosis of suprastomal airway. The disadvantage of SBFT is more time-consuming procedure than the conventional tracheostomy, A retrospective analysis of 8 patients undergoing SBFT between June, 1994 and March, 1995 in Dankook University Hospital was performed to present the surgical technique and com-plication rates. The average duration of follow up was 11 months. The complications were consisted of a wound infection and a sternal granulation. The other complications including wound dehiscence, tracheitis, pneumonia, tracheal granulation, sternal narrowing and subglottic stenosis were not experienced.

Gunshot injuries can range from the most minor to the life-threatening. Multidisciplinary care is required for successful management of patients, In the acute phase, care may involve emergency surgeons, anaesthesists, neurosurgeons, ophthalmic surgeons, vascular surgeons, ENT specialist in addition to the oral and maxillofacial surgeons. Afterwards, definitive treatment of facial gunshot injuries depends ultimately on the abilities and skills of the oral and maxillofacial surgeons, and their appreciation of such injuries. The timing and sequence of the surgical procedures used for reconstruction and rehabilitation of maxillofacial gunshot injuries are crucial to a successful outcome and aesthetic result. If incorrect, they may lead indefinitely to infection, graft rejection, wound dehiscence with consequent multiple revisional operations and complication which will prolong hospital stay and increase treatment costs and morbidity on those patients. We present a gunshot case of a 46-year-old man who tried to commit sucide, and have avulsive and penerating wounds on the face and the neck. We removed the scattered bullets and fragments successfully and the wounds were closed primarily.

The latissimus dorsi flap has high vascularity and is helpful for the reconstruction of infected areas. Herein, we present a patient with recurrent infections and soft-tissue defects who underwent cranial reconstruction using a free latissimus dorsi flap. The patient had undergone craniectomy and reconstruction using alloplastic bone 18 years previously. A scalp defect accompanied by infection occurred five years ago, and patient underwent reconstruction using a free flap at another hospital; however, the problem persisted. After debridement and bone flap removal, the right latissimus dorsi musculocutaneous flap was elevated, and the thoracodorsal artery and vein were anastomosed end-to-end to the right superficial temporal artery and vein. Methicillin-resistant Staphylococcus aureus was eradicated, and the flap survived. Cranioplasty was performed eight months later, and one year follow-up proceeded without complications. Effective reconstruction and cranioplasty are possible using the free latissimus dorsi musculocutaneous flap, even on scalp with persistent infections and soft-tissue defects.

Between March 1978 and December 1985, 39 patients were admitted to our hospital & surgery was performed to 27 patients. Among 39 patients, male patients were 31 cases, female 8 cases and the age ranged from 42 years old to 69 yrs old with the average of 55 years old. Main symptoms of esophageal cancer were dysphagia [6%], weight loss [20%], retrosternal and epicardial discomfort [18%], hoarseness [13%], and hiccup [5%]. The anatomical locations of esophageal cancer were followed as; 51% in lower esophagus & cardia, 44% in middle, and 5% in upper esophagus. Among 27 cases, 5 cases were managed by feeding gastrostomy and jejunostomy due to inoperability, 19 cases by esophagogastrostomy, and 3 cases by colon bypass with the resection of esophageal cancer. Postoperative complications were noticed in 7 cases, such as anastomotic leakage in 2 cases [7%], respiratory insufficiency in 2 cases [7%], intussusception in 1 case [4%], wound dehiscence in 1 case [4%], and hepatitis in 1 case [4%]. Among 2 respiratory insufficiency, 2 patients die as a result of that complication and operative mortality was 7%.
