갑상선절제술은 내분비 외과의사가 하는 수술 중 가장 안전한 수술이지만 수술 중 기도나 식도가 손상 받을 수 있으므로 각별한 주의를 기울여야 한다. 특히 기도 괴사와 같이 생명에 위협을 주는 합병증이 있음을 유념해야 한다. 본 논문은 갑상선 전 절제술과 승모판 치환술을 함께 받은 72세 여성환자가 수술 후 3일만에 기도 괴사가 발생한 케이스이다. 3개의 기관륜에 걸쳐 괴사가 발생되어 있었다. 괴사된 조직을 제거하고, 이후 지속적인 괴사조직에 대한 제거와 치료와 적으로 기관개창술을 시행하고, 자연폐쇄를 유도하여 성공적으로 치료되었다. 비슷한 여러 논문들을 살펴본 결과 기도 괴사를 유발하는 요인으로는 조절되지 않는 기침, 여성, 갑상샘중독 결절, 기도 삽관 시 발생되는 손상, 삽관튜브 커프의 과팽창으로 기도가 장시간 높은 압력으로 압박되었을 때, 적절하기 않은 커프 크기, 삽관튜브 커프의 공기를 빼지 않고 무리하게 움직였을 때, 출혈이 많을 때, 과도한 전기소작으로 인한 손상, 기도로 가는 혈관손상으로 인한 혈액공급의 차단, 감염 등으로 보고 있다. 치료는 기도의 괴사와 감염의 정도에 따라 달라질 수 있다. 일차 봉합술, 일시적 스토마 형성, 일시적 기관조루술, 단단연결술, 기도 스텐트 설치술, 근육피판 재건술, 보존적 치료 등을 시행할 수 있다. 기도 괴사에 대한 위험인자와 치료에 대해서는 아직 확실히 적립되지 않은 상태이다. 드문 합병증이지만 생명을 위협할 수 있는 이러한 합병증에 대해 항상 염두 해 두고 수술 시 신중을 기하고 문제 발생시 신속한 대응을 해야겠다.

A 49-year-old man visited our hospital via the emergency room. He had suffered chest trauma by falling down. His chest X-Ray showed pneumomediastinum with pneumopericardium. We checked the Chest CT, and it showed pneumopericardium without any injury to the other organs, the compressed heart and a minimal pneumothorax on the left hemithorax. Closed thoracostomy was then done under local anesthesia. We then performed open pericardiostomy under general anesthesia. We got a good result and so we report on this case.

Dentigerous cyst is one of the most prevalent types of odontogenic cysts in the jaw. Usually dentigerous cysts begin to develope through an accumulation of fluid between remnants of the enamel organ and subjacent tooth crown which is developing or submerged. The teeth most often involved are mandibular third molars, maxillary canines, and mandibular premolars. And the cysts usually occur in the second or third decade of life. The treatment of dentigerous cysts-enucleation, marsupialization, and fenestration-is dictated by the size, environmental structures of the lesion, and desirability of conserving involved tooth. Marsupialization is a conservative technique which allows the reduction or elimination of cystic lesion by making it an accessory compartment of the oral cavity in the case where complete enucleation is not desirable. Marsupialization is thought to be the most suitable method of treatment for the conserving of the involved tooth, thus guiding eruption of it. We report the positive outcome got from marsupialization in dentigerous cysts with review of literature.

Primary pericardial malignant mesothelioma is a lethal and rare cardiac neoplasm of mesodermal origin. Most cases are associated with history of pericarditis with constriction and/or tamponade. Authors experienced a case of primary pericardial malignant mesothelioma in a 55-year old female who had suffered from dyspnea and chest pain. Pericardial nodules revealed intense uptake by FDG-PET scan and confirmed as primary pericardial malignant mesothelioma by thoracoscopic biopsy. Here we report this case with a brief review of the relevant literatures.

Maxillary canines are the most commonly impacted or ectopically erupted teeth. If we find the abnormality of maxillary canines early, we can manage it reasonably and systematically. If we cannot see the spontaneous normalization at the periodic recall, primary canine extraction will be the next treatment choice. However, if the primary canine is extracted too early, the extraction socket will be filled with hard bone and then the eruption pathway can be locked. So it is more beneficial to extract the primary canine at the period about 6 months before the normal canine eruption time. The next treatment plan can be surgical and orthodontic approaches before the root apical closure of the impacted canine. Sometimes, surgical extraction and further prosthetic procedure can be needed for a severely malposed impacted canine or badly resorpted incisor. This is the case of the idiopathic mesial movement of impacted maxillary canines.

Mucocele is a mucous retention phenomenon which is caused by a laceration to the duct of minor salivary glands causing extravasation of mucin into the connective tissue forming a cyst-like space. Sialolithiasis of minor salivary glands and chronic obstruction of salivary glands may also cause such a phenomenon. Mucocele is a smooth, rounded sessile mass with diameters varying from 1 to 15mm of sudden appearance. Mucocele tying directly beneath the mucosa may rupture spontaneously and decrease in size, but frequently recurs. Lower lip is most frequently affected, and the mouth floor and buccal vestibule may also be affected. Enucleation of the cyst is needed and removal of minor salivary glands, marsupialization and cryotherapy may also be done. The mucocele frequently recurs after its removal. A 1-year-old female patient visited the hospital with a complaint of a swelling on the lower lip since 4 months before. She had no pain history but 4 months ago, fell and such symptom appeared since then. On her first visit, a bullous solid, opaque lesion of 5mm in diameter was noted. Treatment choice of surgical approach and nonsurgical approach were explained to the guardian. Considering the patient's age, the guardian agreed to a nonsurgical procedure. Treatment was carried out by tieing 3-0 silk to the base of the lesion. One week later, the tie loosened and was re-tied. A week later, the mucocele disappeared. Mucocele on the lower lip may be usually be treated by surgical removal, but this may traumatize the surrounding minor salivary gland causing it to recur. Also, surgicial removal may induce an ischemic change causing sialometaplasia. In case of young patients or children with management problems, non-surgical methods such as this tie method may be used. This tie method does not need any local anesthesia and has no pain, no secondary infection, and low bleeding tendency.

Purpose: Xanthomatosis of the Achilles tendons is rare. In some patients, however, the lesions in the Achilles tendon need to be removed, which may be painful and disfiguring. While studies of successful surgical outcomes for the total resection and reconstruction of the Achilles tendon have been reported, reconstruction surgery has a technical challenge, and extended surgical exposures are required. This study analyzed five cases of bilateral xanthoma of the Achilles tendon, which was treated surgically using a wedge-shaped tendon-sparing approach to eliminate the need for tendon reconstruction. Materials and Methods: From July 2010 to May 2018, five patients with xanthomatosis in both Achilles tendons underwent wedge-shaped tendon preserving surgery. The average age was 49 years (range, 40-55 years), and the follow-up period was 21.4 months (range, 12-31 months). The patients consisted of three males and two females. Complications related to surgery were recorded. The outcome measures included the range of motion of the ankle joint, American Orthopaedic Foot and ankle Society (AOFAS) ankle/hindfoot score, and visual analogue scale (VAS) for overall satisfaction at the last follow-up. The availability of a single-limb heel raise and returning time to work were also measured. Results: Wound dehiscence that did not require secondary surgery was noted in one patient. At the last follow-up, the range of motion of the ankle joint was normal in all patients. The mean AOFAS ankle/hindfoot score was 91 (range, 85-96) and the VAS for the overall satisfaction ranged from 8 to 10. The average time between surgery and return to work was 27.6 days (range, 17-58 days) and all patients could perform a single-limb heel raise test. Conclusion: The tendon-sparing technique, which can preserve the anatomical functioning of the Achilles tendon, could be an excellent surgical approach because it has very promising functional and cosmetic surgical outcomes in patients with Achilles tendon xanthomatosis.

When many factors involved in the eruption of the teeth act as negative effects, they can cause eruption disturbance. Periodic observation, space acquirement, surgical exposure, orthodontic traction, orthodontic traction accompanied with surgical exposure, and surgical repositioning are considered as the treatment options of an impacted tooth, which is a form of eruption disturbance. In the first case, a male patient, age 9, visited Yonsei University Dental Hospital (YUDH) with a chief complaint of ectopic impaction of the upper left lateral incisor. We extracted the upper left primary lateral incisor and primary canine, and 5 months later, a window opening procedure was executed. Eight months later, the upper left lateral incisor partially erupted, and 18 months after the extraction, the axis of the tooth improved and the tooth erupted spontaneously. In the second case, a male patient, age 10, visited YUDH with a chief complaint of ectopic impaction of the upper right first premolar. We extracted the upper right first primary molar. Ten months later, the upper right first premolar erupted partially, and 19 months after the extraction, the upper right first premolar erupted spontaneously. We reported two cases in which improvement of eruption path and spontaneous eruption of an ectopic impacted tooth was achieved by extracting the deciduous tooth which interfered with the proper eruption of it.

Purpose: We aimed to evaluate the efficacy of Octyl-2-cyanoacrylate (Dermabond$^{TM}$) as a topical skin adhesive for pediatric urologic open surgery. Methods: From August 2010 to August 2011, we retrospectively evaluated pediatric patients who underwent urologic open surgery at our institution. A total of 128 pediatric patients with 210 incisions used Dermabond$^{TM}$ for skin closure. Results: We divided the 128 patients into 3 groups according to type of surgery. Group 1 underwent hydrocelectomy (55 cases, 41.3%), Group 2 underwent orchiopexy (43 cases, 32.3%), Group 3 underwent penoplasty (35 cases, 26.4%). One hundred and twenty eight patients who underwent 133 surgeries in total, with a total of 210 incisions visited our outpatient department postoperatively, and a total of 5 wound complications (2.3%) occurred, but were simple inflammations and no dehiscence was observed. When analyzed according to groups, no wound problems occurred in Group 1 (0/55, 0%), one occurred in Group 2 (1/43, 2.3%) and four cases occurred in Group 3 (4/35, 11.4%) respectively. When re-analyzed according to wound locations, one occurred in an inguinal wound (1/120, 0.83%), none occurred in scrotal wounds (0/55, 0%), and four occurred in penile wounds (4/35, 11.4%). In Group 3, the incidence of penile wounds was significantly increased compared to other groups (P=0.008). All 5 wound problems were inflammatory and healed at an average of 13.8 days (13-15 days) with antibiotic ointment application only. Conclusion: Dermabond$^{TM}$ is feasible and safe topical skin adhesive alternative to standard skin suture in pediatric urologic surgery. However, further research about its efficacy and safety could be valuable in the future.

Background: Twelve patients with acyanotic tetralogy of Fallot(TOF), characterized by the combination of a malaligned ventricular septal defect(VSD) and infundibular pulmonic stenosis with the clinical finding of acyanosis at rest, underwent surgical correction between January 1988 and July 1997. Materials and methods: 9.92% of patients with the diagnosis of TOF were acyanotic TOF in the same period. Ages ranged from 12 to 42 months(mean 25.2 months). 2D-echocardiographic studies, cardiac catheterization, and angiocardiograms were performed in all patients before operation. The preoperative mean systemic arterial oxygen saturation was 93.5%. According to the 2D-echocardiographic analysis, there was Lt-to-Rt shunt through VSD in 4 patients, bidirectional shunt in 2 patients, and no shunt in 6 patients. Results: The preoperative mean right ventricle to pulmonary artery(RV-PA) pressure gradients were 52.3 mmHg on 2D- echocardiogram and 48.4 mmHg on cardiac catheterization. The repair of ventricular septal defect was performed through a right atrial approach and the hypertrophic infundibular muscle bundles were resected by the transatrial and transpulmonary approach. Six patients(50%) received a transannular patch. The mean cardiopulmonary bypass time was 135.0 minutes, and the aortic crossclamp time was 87.8 minutes. Postoperative complications included bleeding necessitating reentry in one and chylothorax in one. No patient died after operation and there were no late deaths. Postoperative 2D-echocardiograms revealed tiny patch dehiscence in 5 cases and a moderate RV-PA pressure gradients(mean 15.3 mmHg). All patients were in New York Heart Association functional class 1 after operation. Conclusions: acyanotic TOF is the uncommon form of TOF, and acyanotic TOF can be repaired with a good outcome.
