The purpose of this paper is to present the potential application of tissue adhesive in the management of traumatized gingival wound in clinical dental hygiene practice. Cyanoacrylate adhesive has been used for closure of superficial laceration without suturing, which is available in periodontal and oral surgery. Small gingival or mucosal lacerations may occur by improper or excessive instrumentation of the dental hygienist during scaling and root planing procedure. In this circumstances, tissue adhesive is very effective, simple, and convenient method as an alternative to conventional wound closure by suturing. The tissue adhesive consists of monomeric n-butyl-2-cyanoacrylate, which polymerizes quickly in contact with tissue fluid. The sutureless treatment of gingival laceration with tissue adhesive has advantages of good esthetic results, less trauma, time saving, antibacterial and hemostatic effects. In addition, local anesthesia as well as re-visit for dressing and removal of suture are not required. Use of tissue adhesive could be beneficial to both dental hygienist and patient in the management of procedural error.

Background Preauricular sinuses are congenital abnormalities caused by a failure of fusion of the primitive tubercles from which the pinna is formed. When persistent or recurring inflammation occurs, surgical excision of the infected tissue should be considered. Preauricular defects inevitably occur as a result of excisions and are often difficult to resolve with a simple suture; a more effective reconstruction technique is required for treating these defects. Methods After total excision of a preauricular sinus, the defect was closed by a plastic surgeon. Based on the depth of the defect and the degree of tension when apposing the wound margins, the surgeon determined whether to use primary closure or a posterior auricular flap. Results A total of 28 cases were examined. In 5 cases, including 2 reoperations for dehiscence after primary repair, reconstruction was performed using posterior auricular transposition flaps. In 16 cases of primary closure, the defects were closed using simple sutures, and in 7 cases, closure was performed after wide undermining. Conclusions If a preauricular defect is limited to the subcutaneous layer and the margins can be easily approximated, primary closure by only simple suturing may be used to perform the repair. If the defect is deep enough to expose the perichondrium or if there is tension when apposing the wound margins, wide undermining should be performed before primary closure. If the extent of the excision exposes cartilage, the procedure follows dehiscence of the primary repair, or the tissue is not sufficiently healthy, the surgeon should use a posterior auricular flap.

The purpose of this study was to determine how often toddlers and preschoolers in kindergartens have accidents and what factors affect the accident rate. The study population consisted of 150 children who were attending at nursery schools and 150 children who were attending at kindergartens. The data was collected from ten nursery schools and five kindergartens from five districts in Daegu. The questionnaires were distributed to teachers of participating nursery schools and kindergartens to be completed using nursing care records in the institutions and by interviewing children's parents about all of the accidents happened in a previous year. Data were collected during the period of August 1 through 31, 2002. The results of the study are as follow: 1. Among 300 children, 282 had 506 accidental injuries during the study period. 2. The month, the day and the time with the highest accident rate were April. Monday, and between 2 and 4 o'clock in the afternoon, respectively. 3. Locations where the injury took place most included nursery schools or kindergartens, around the homes of the children, and inside the home. 4. Most accidents were occurred due to lack of carefulness of the children, and the most prevalent forms of injury was abrasions. 5. Most frequently injured part of the body was legs of the children. 6. Most injuries were healed within three days and required first aid measures to disinfect the wound. Mostly, these were performed by family members at home. Some children go to the hospital to suture the open wound. Most frequent type of complication was scar formation and the cost of the treatment ranged from 9,000 to 30,000 won. 7. Children's age. sex, birth order. personality. type of family composition. type of residency. father's occupation, father's age, and mother's age were significantly related to the frequency of injury among children. Children who were in nursery schools and kindergartens need their assessment for accident involving condition according to seasons, time. place. This study provided a very useful and important data to prepare accident prevention education program and accident prevention strategies, and to develop Injury Surveillance System.

Purpose: Sacrococcygeal pilonidal sinus is a chronic inflammatory disease that mostly affects young people, which warrants surgical intervention. Although many surgical methods have been suggested, an optimal surgical method remains controversial because of high recurrence rates and postoperative complications. The objective of this study is to evaluate the results of wide excision and coverage with fasciocutaneous advancement flap for the treatment of sacrococcygeal pilonidal sinus, and to assess the usefulness of this method Methods: From May 1995 to October 2006, the authors treated 19 patients with the use of coverage with fasciocutaneous flap after wide excision. The results were evaluated regarding recurrence rates, complications, and the change in sensitivity of the gluteal region after surgery. The follow-up period was 7 to 142 months (mean, 76 months). All patients were male. Results: Postoperative complications were wound infection at the suction drain insertion site and skin necrosis around the suture margin in one case, respectively. During the follow up period, only one recurrence (5.3%) was seen in fifth postoperative month, which was successfully treated by the same operative procedure. There was no other complications such as seroma, hematoma, wound dehiscence and flap loss. Extensive scarring and anatomic distortion did not occur in the reconstructed area. In addition, sensitivity of the gluteal region did not diminish. The aesthetic results were satisfactory for all patients as well. Conclusion: The authors advocate that fasciocutaneous flap closure be a good alternative method to cover defects after the excision of sacrococcygeal pilonidal sinus.

This is a retrospective study on emergency patients with active oral bleeding. The study was based on a series of 135 patients treated as emergency patients at Wonju Christian Hospital, from Jan. 1, 1997, to Dec. 31, 2001. The postoperative bleeding was the most frequent cause of active oral bleeding in emergency room and bleeding from trauma and medically compromised (bleeding disorders) patients were next in order of frequency. In the injury of maxillofacial vessels, peak incidence was occurred in the inferior alveolar vessel (42.9%), followed by the submucosal vessel of lip & cheek, the superior alveolar vessel, and sublingual vessels. The most common disease of bleeding disorders was vascular wall alteration (infection, etc), followed by liver disease, thrombocytopenic purpura, anti-coagulation drugs in order. In the characteristics of dental diseases on bleeding disorders, periodontal disease and alveolar osteitis (osteomyelitis) were more common. The hemostasis was most obtained by use of wound suture, simple pressure dressing, drainage for infection control and primary interdental wiring of fracture. In the complication group, the infrequent incidence was showed in vomiting, hypovolemic shock, syncope, recurred bleeding & aspiration pneumonia. In the uncontrolled oral bleeding, the injured vessels were suspected as skull base & ethmoidal vessels. In this study, authors found that the close cooperation between the dentistry (Oral and maxillofacial surgery) and the medicine (emergency & internal medicine) was the most important for early proper control of active oral bleeding. And then post-operative wound closure, drainage for infection control and previous systemic evaluation of bleeding disorders were critical for the prevention of postoperative bleeding in the local dental clinic.

Peripheral nerve injury occurs mostly by trauma and is usually associated with fracture of bone and joint, muscular injury and tendon injury and it also evokes paralysis and anesthesia. When treatment of peripheral nerve injury is considered,, the modality of treatment is decided by the general condition of the patient, type of injury, associated injuries and the condition of wound. To get the maximum results, surgical treatment and reconstruction and rehabilitation should all go in hand-in-hand. From January 1985 to December 1994, we observed 61 patients that had operation without reconstruction due to peripheral nerve injury with a follow-up period of more than 1 year. Among the 61 patients, 44 were men(72%) and 17 were women(28%). Follow-up period was average 19 months. Age distribution was mostly in their twenties with a mean age of 28 years. Time interval of operation after injury was average 11 months. Trauma was the main cause of peripheral nerve injuries with a proportion of 87%. 31 patients had neurorrhaphy, in which case 14 patients had stay suture and 17 patients did not. 14 patients had nerve graft, and 16 patients had neurolysis. We used our scales to compare the results of surgery on the basis of British Research Council System. We gave scores to every sensory and motor scale to estimate functional improvement and emphasized on motor functional improvement. The total score = sensory score + ($2{\times}motor$ score). We considered 8-9 points as excellent, 6-7 points as good, 2-5 points as fair, 0-1 points as poor result. We considered excellent and good as much improved. Excellent and good results were obtained in 13 out of 14 neurorrhaphy with stay suture(93%), 12 out of 17 neurorrhaphy without stay suture(71%), 6 out of 14 nerve graft(43%), 12 out of 16 neurolysis(75%). Among the patients with neurorrhaphy done within 3 months, 11 out of 14(86%) showed improvement, but among the patients after 4 months 3 out of 17(76%) showed improvement. 84% of improvement was observed in the patients with time interval from injury to surgery within 3 months, and 64% in the patients with time interval after 4 months. In the aspect of age, 77% with the age below 20 years, 70% with the age between 21 and 30 years, 66% with the age above 31 years showed improvement. We conclude that considering degree of injury, time interval from injury and age with the adequate method of treatment, we can obtain good results from surgery.

The advantages of the $CO_2$ laser are offset by the delay in laser wound healing secondary to thermal damage. To minimize the undesirable thermal damage of the $CO_2$ laser, investigators have developed technical advances in the delivery system of the laser energy. This study compared tissue healing of the continuous and the pulsed modes $CO_2$ laser wounds in an animal surgery model. Five healthy Landrace and Yorkshire mixed breeds of both genders were used (45-51 kg, 4-6 months old, three males and two females). A full thickness wound of skin ($2{\times}2{\times}2cm^2$) was made over on the each pig's both sides of dorsal midline at 0, 7, 14, and 18 days. The wounds created at 18, 14, 7 and 0 days were named post-wounding day (PWD) 3, 7, 14 and 21, respectively. In each pig, one wound (left side) was treated pulsed $CO_2$ laser and the other wound (right side) was treated continuous wave $CO_2$ laser. Each wound was closed with two interrupted suture of 3-0 sutures. At 21 days after initial wounding, each wound was taken for histological evaluations. The degrees of reepithelialization were performed more prominently in the pulsed mode group than in the continuous mode group. The degrees of granulation were greater significantly in pulsed mode group than those in the continuous mode on PWD 3 (p < 0.05). The degrees of fibroblasts in the pulsed mode group were greater significantly in comparison to those in the continuous mode group on PWD 7, (p < 0.05). In conclusion, reepithelialization, granulation and fibroblasts in the pulsed mode group were greater markedly in comparison to those in the continuous mode group. It was considered that pulsed mode $CO_2$ laser was more suitable for the skin incision than the continuous mode $CO_2$ laser.

The closure of any circular or asymmetric wound can result in puckering or an excess of tissue known as a 'dog ear'. Understanding the mechanism of dog ear formation is a fundamental requirement necessary to facilitate an appropriate treatment. Many solutions have been reported in the literature, but in all cases, the correction entails the extension of the scar and the sacrifice of the dermal plexus. Here, we propose a novel technique of dog ear correction by using a three-bite suture that sequentially pierces the deep fascial plane and each dog ear's margin, thus allowing for flattening the dog ear by anchoring the over-projecting tissue to the deep plane. The three-bite technique proved to be a fast, easy, and versatile method of immediate dog ear correction without extending the scar, while maintaining a full and complete local skin blood supply.

Twenty nine adult patients underwent surgical esohpagectomy and one, bypass procedure for documented carcinoma of esophagus and cadiac portion of stomach at Chonnam National University Hospital from Jan 1986 to April 1991. There were several kinds of esophagectomies including through transhiatal, left thoracotomy only, laparotomy and thoracotomy, and laparotomy and right thoracotomy and cervical incision. Twenty five and squamous cell carcinoma and 5, adenocarcinoma. The tumor locations were the upper third in 3, middle third in 12, lower third in 10 and cardiac portion of stomach in 5. After operation, 8[27%] patients were classified in Stage IIa, 6[20%] patients in Stage IIb, 15 patients[50%] in Stage III and one patient in Stage IV. Major postoperative complications included anastomotic narrowing in 3, limited suture line leak in 2, wound infection in 2, hoarseness in 2, pseudomembraneous enterocolitis in 1 and herpes zoster in 1. There was no death within 30 days of operation. Ten months survival was 100% for patients with Stage lIa, 67% for patients with Stage IIb, 50% for patients with Stage III. Furthermore, 20 months survival was 75% in IIIa, 33% in IIb, and 40% in III. But there were no significant differences in survivals among the stage. The actuarial survival is 58% at one year and 41% at two years, The periods of average survival is 589 days after operation.

With the adevance of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. We have experienced these diseased of the 3 cases in our department. The first case was a 25 year old male who was severe dyspneic and subcutaneous emphysema, hemoptysis, and hemopneumothorax of both side were noted. During tracheostomy, it was found that the 2net ring of the trachea was ruptured. No definitive procedure was made on admission. Corrective surgery was performed with end-to-end anastomosis on 31 post-traumatic day. The second case was a 43 year old female who received multiple stab wounds on the anterior neck and it was found that the cricoid cartilage was transected partially. The injured cartilage was approximated with interrupted suture of No. 600 wire. The third case was a 19 year old male who had sustained a compression chest injury without external wound or rib fracture. At five days after trauma, he had suffered from dyspnea, and obstruction of the left main bronchus due to traumatic bronchial rupture was confirmed by means of bronchoscopy and bronchography at two weeks after the trauma. End-to-end anastomosis of the bronchus was performed and the left lung was aerated well. Mild postoperative stenosis of trachea was remained in the first case. Others were uneventful.
