The laryngeal foreign bodies are not common among the foreign bodies in the air and food passage, however, it would cause fatal airway obstruction without performing immediate endoscopic removal or emergency tracheostomy procedure. It is our intent to report three cases of laryngeal foreign bodies, and to discuss diagnostic procedures, preventive measures and management of this problems.

Severe childhood asthma is a complicated and heterogeneous disorder with distinct phenotypes. Children with severe asthma have more persistent symptoms despite receiving treatment, more atopy, greater airway obstruction, and more air trapping than those with mild-to-moderate asthma. They also have higher morbidity and substantial airflow limitations that persist throughout adulthood. Identification of the phenotype clusters and endotypes of severe asthma can allow further modulation of the natural history of severe asthma and may provide the pathophysiologic rationale for appropriate management strategies.

This case describes a tracheal stenosis complicated by endobronchial truberculosis. A 50-year-old female with progressive dyspnea was referred to us for the management of long segmental tracheal stenosis. Treatment modalities for tracheal stenosis include open surgical resectin and reconstruction, mechanical dilation, laser resection, and placement of an airway prosthesis. The following is a report of a successful treatment of a long segmental tracheal stenosis through a tracheal augmentation and the use of al Bovine pericardium. This technique may provide a relief from tracheal stenosis.

The safety and success of dental sedation for children depend mainly on respiratory status of patients. A special condition, that is, nasal breathing in supine position with their oral airway blocked by rubber dam, should be considered. Therefore, irrespective of medical consultation, pediatric dentists themselves should do respiratory assessment especially adenotonsillar hypertrophy, nasal obstruction, posterior nasal drainage and airway hypersensitivity. Patients with sinusitis, allergic rhinitis, asthma, snoring and OSAS(obstructive sleep apnea syndrome) can induce the sedation failure and complete management of these can improve the safety of dental sedation.

본 연구는 병원전 단계 기도기 시뮬레이션 교육에 대한 연구로 연구대상은 응급구조학과 4학년 학생 22명으로 구성하였다. 교육시간은 10분 동안 3개의 기도유지기에 대한 전체 강의가 있었고, 10분 동안 마네킹을 이용하여 세 가지 기도기의 사용방법을 교육하고 실습을 시행하였다. 응급구조학과 학생을 대상으로 Airway management trainer Simman를 이용한 기도 내 이물 제거 모델에서 매킨토시후두경과 GlideScope and the AWS$^{(R)}$, McGrath$^{(R)}$ 비디오 후두경의 기관내 삽관 성공률과 삽관 시간, 시행자의 선호도를 비교한 결과 의미 있는 차이를 보였다. 마네킨을 이용한 병원전 기도기인 1차 시도에서는 유의한 차이를 보였지만 2차에서 숙련이 된 경우이라서 큰차이를 보이지 않았다. 기관내 삽관 기구의 선호도 조사에서는 Pentax AWS를 가장 선호하였다.

A thyroid cartilage fracture is a rare entity and can be overlooked easily. Such cases are difficult to diagnose, and assessment and treatment guidelines are difficult to determine. CT of the neck region may be useful when acute airway intervention is not required or when more information regarding the neck's anatomy is required for management decisions. We describe a case of a thyroid cartilage fracture with displacement. In the emergency department (ED), neck CT and fiberoptic nasopharyngoscopy were used to assess the status of the patient's (a male) vocal chords immediately. He remained unable to phonate continuously. After an immediate assessment, we decided to use steroid and conservative therapy. The patient had a good recovery and was without symptoms one month after injury. There is no question that early surgical repair of neck injuries affords the best results for airway and voice patency in most cases however, we suspect that surgical repair is not needed in all cases. Early recognition and an accurate therapy plan for a thyroid fracture with displacement are essential. Therefore, the emergency physician's immediate and careful decision based on endoscopy and neck CT is important for the patient's long-term recovery.

Dental implantation in the mandibular anterior region is considered a safe and reliable surgical procedure. On the other hand, several articles have reported that inadvertent hemorrhage of the sublingual artery can result in life-threatening airway obstruction. Surgical ligation under intubation or tracheostomy is the most widely used approach for controlling mouth floor bleeding in this highly vascular region. Nonetheless, surgically exploring the bleeding focus is difficult because of anatomical distortion followed by widespread edema and swelling. Since swelling of the mouth floor advances quickly, timely management is essential for favorable postoperative outcome. This paper reports a case of immediate hemorrhage control with angiographic embolization to perform rapid hemostasis before the ongoing swelling causes airway obstruction. Less invasive, angiographic embolization can prevent neurovascular damage during a surgical exploration of injured vascular structures on the mouth floor.

Background and Objectives： Primary benign masses in subglottis and trachea are rare. Symptoms of tracheal obstruction are similar to those of bronchial asthma, chronic bronchitis, as well as malignant lesions. Materials and Methods： Eight patients with benign tracheal masses from April 1992 through June 2001, at otolaryngology-head and neck surgery. department of Seoul national university hospital were studied by retrospective medical record review. Results : They were 3 females and 5 males aged from 0 to 57 years. The pathologies of the intratracheal masses were lipoma. tuberculosis, pleomorphic adenoma, hemangioma(two case), reparative giant cell granuloma, epithelial inclusion cyst and nonspecific lymphadenopathy, respectively. The most characteristic symptoms were dyspnea and stridor, both inspiratory and expiratory. Five of them had been treated as bronchial asthma. Conclusion： For the management of patients with the subglottis and tracheal masses, it is important to establish secure airway. regardless of pathology of the masses. The diagnosis should be considered in any patient with asthma-like manifestation, especially who fails to respond to medical treatment. It is necessary to examine the airway thoroughly, and chest and simple cervical X-ray may contribute to the diagnosis of possible intratracheal mass.

Purpose: Difficult organs or locations or inadequate tube intubations can cause complications. There are some cases in which the tube location changes or the tube is removed due to processing inside the organ while installing the stylet or rapid stylet removal. Thus, this study aimed to evaluate and develop an integrated intubation tube with stylet (IITS) for easier intubation of organs in emergency cases and reduce complications caused by the stylet. Methods: This study used a "Laerdal Airway Management Trainer". For stylet intubation, procedure No. 14 of the national practical test protocol was followed, but the removal step was omitted. In this study, each emergency case was intubated with an IITS, in which the stylet was not inserted or removed separately even though it has the function of an organ intubation stylet. Results: The existing classic ET intubation method had a success rate of 100% and had an average intubation time of 21.75 seconds, The developed IITS method was also successful in all cases and had an average intubation time of 15.78 seconds. Conclusion: Application of an IITS is expected to reduce intubation time and decrease inappropriate depth and intubation failure due to stylet removal, therefore improving the efficiency of airway maintenance.
