Objective : Cricothyrotomy and tracheostomy are performed by physicians in various disciplines. It is important to know the comprehensive anatomy of the laryngotracheal region. Hemorrhage, esophageal injury, recurrent laryngeal nerve injury, pneumothorax, hemothorax, false passage of the tube and tracheal stenosis after decannulation are well known complications of the cricothyrotomy and tracheostomy. Cricothyrotomy and tracheostomy should be performed without complications and as quickly as possible with regards the patients' clinical condition. Methods : A total of 40 cadaver necks were dissected in this study. The trachea and larynx and the relationship between the trachea and larynx and the surrounding structures was investigated. The tracheal cartilages and annular ligaments were counted and the relationship between tracheal cartilages and the thyroid gland and vascular structures was investigated. We performed cricothyrotomy and tracheostomy in eleven cadavers while simulating intensive care unit conditions to determine the duration of those procedures. Results : There were 11 tracheal cartilages and 10 annular ligaments between the cricoid cartilage and sternal notch. The average length of trachea between the cricoid cartilage and the suprasternal notch was 6.9 to 8.2 cm. The cricothyroid muscle and cricothyroid ligament were observed and dissected and no vital anatomic structure detected. The average length and width of the cricothyroid ligament was 8 to 12 mm and 8 to 10 mm, respectively. There was a statistically significant difference between the surgical time required for cricothyrotomy and tracheostomy (p < 0.0001). Conclusion : Tracheostomy and cricothyrotomy have a low complication rate if the person performing the procedure has thorough knowledge of the neck anatomy. The choice of tracheostomy or cricothyrotomy to establish an airway depends on the patients' clinical condition, for instance; cricothyrotomy should be preferred in patients with cervicothoracal injury or dislocation who suffer from respiratory dysfunction. Furthermore; if a patient is under risk of hypoxia or anoxia due to a difficult airway, cricothyrotomy should be preferred rather than tracheostomy.

Tracheal stenosis is due to tracheostomy or prolonged intubation. Development of tracheal stenosis following tracheostomy is very serious complication. In recent practice, tracheostomy has became more popular because of increased occasions of major and minor traumas. At the Dept. of thoracic surgery, Chonbuk national university hospital, we have experienced one case of tracheal stenosis following tracheostomy for assisted ventilation. Chest X-ray revealed the narrowing of trachea at cervicothoracic junction due to previous tracheostomy. We resected the narrow segment & tracheal reconstruction was performed with an excellent result in postoperative periods. Postoperative air tracheogram did not reveal demonstrable narrowing of air filled trachea.

Tracheostomy is a relatively common surgical procedure that is performed easily in an operating room or intensive care unit. Open tracheostomy is needed in patients requiring prolonged ventilation when percutaneous tracheostomy is inappropriate. Sometimes, it is difficult to achieve bleeding control in the peritracheal soft tissue, and in such cases, we usually use diathermy. However, the possibility of an electrocautery-ignited surgical field fire can be overlooked during the procedure. This case report serves as a reminder that the risk of a surgical field fire during tracheostomy is real, particularly in patients requiring high-oxygen therapy.

Tracheostomy is considered as a first treatment, when oral intubation seems to be difficult in patient who present severe upper airway obstruction. Generally, tracheostomy is performed in supine position. But if airway obstruction is severe enough to cause dyspnea, low oxygen saturation and inability to maintain supine position, tracheostomy should be performed in sitting position. The authors report a case of successful tracheostomy using high flow nasal cannula which help to maintain stable oxygen saturation and respiration in patients with laryngeal cancer.

Objective : To evaluate the magnetic resonance (MR) imaging features that have a statistically significant association with the need for a tracheostomy in patients with cervical spinal cord injury (SCI) during the acute stage of injury. Methods : This study retrospectively reviewed the clinical data of 130 patients with cervical SCI. We analyzed the factors believed to increase the risk of requiring a tracheostomy, including the severity of SCI, the level of injury as determined by radiological assessment, three quantitative MR imaging parameters, and eleven qualitative MR imaging parameters. Results : Significant differences between the non-tracheostomy and tracheostomy groups were determined by the following five factors on multivariate analysis : complete SCI (p=0.007), the radiological level of C5 and above (p=0.038), maximum canal compromise (MCC) (p=0.010), lesion length (p=0.022), and osteophyte formation (p=0.015). For the MCC, the cut-off value was 46%, and the risk of requiring a tracheostomy was three times higher at an interval between 50-60% and ten times higher between 60-70%. For lesion length, the cut-off value was 20 mm, and the risk of requiring a tracheostomy was two times higher at an interval between 20-30 mm and fourteen times higher between 40-50 mm. Conclusion : The American Spinal Injury Association grade A, a radiological injury level of C5 and above, an MCC ${\geq}50%$, a lesion length ${\geq}20mm$, and osteophyte formation at the level of injury were considered to be predictive values for requiring tracheostomy intervention in patients with cervical SCI.

Background and Objectives : Obstructive laryngeal cancers have to be managed with tracheostomy, which has been reported with increased local or stomal recurrence. Stomal recurrence after treatment of laryngeal cancer is one of the most serious issues in the management of laryngeal cancer. Prognosis of locally advanced laryngeal cancer in patients with previous tracheostomy is evaluated. Materials and Methods : Between 1996 and 2007, 174 patients with previously untreated advanced laryngeal cancer(stage III, IV) were enrolled. Overall survival(OS) and disease specific survival(DSS) according to the presence of previous tracheostomy were compared. OS and DSS of the groups with different duration from tracheostomy to treatment were compared. Results : Among 174 patients with advanced laryngeal cancer, previous tracheostomy was performed in 24 patients. Of 24 patients, there were stomal recurrences in 5 patients. DSS of previous tracheostomy group and that of the other group were statistically different(p=0.001). There was statistical significant difference between OS of groups which start treatment more than 14 days after tracheostomy and within 14 days(p=0.03). Conclusions : If possible, Previous tracheostomy should be avoided and if it is inevitable, the elective treatment should be recommended at least within 2 weeks.

기관절제술은 기도확보를 위해 다양한 임상적 상황에서 행해지는 술식으로 1546년에 Brasabola에 의해 처음 성공적으로 시행되었다. 기관절제술의 적응증으로는 상기도 폐쇄의 완화, pulmonary toilet의 촉진, dead space의 감소 및 mechanical ventilation의 장기 사용시 등을 들 수 있겠다. 그동안 term에도 변화가 있었는데, 1718년 까지는 "bronchotomy"란 term 이 사용되었고 그후 "tracheotomy"란 term 이 사용되었으나 1820년 이후에는 "tracheostomy"란 term 이 나오게 되어 현재 이 두가지 term 이 구별없이 사용되고 있다. 기도폐쇄를 야기시킬 수 있는 악안면 부위의 외상 혹은 여러가지 질병의 증가 추세로인해 구강외과의사가 기관절제술을 시행해야할 상황을빈번히 맞게 된다. 이에, 본 교실에서 기관절제술을 시행한 31 명의 환자에 대한 임상적 고찰을 통해 숙련된 기관절제술 및 그 처치능력의 중요성을 보고하는 바이다.

Purpose: The purpose of this research was to develop and train caregivers in tracheostomy tube care using a self-management program to assist patients with an 'at home' tracheostomy procedure. Caregivers' self-efficacy and knowledge of tracheostomy management before and after the training was also identified. Methods: Research participants were the main caregivers for patients with tracheostomies who were affiliated with a 'Home Healthcare Center'. Training and observation were done at 'A Hospital' and 'G Hospital' both affiliated with 'K University' in Seoul. Data were collected from May 3, 2010 to January 25, 2011 and analyzed using Wilcoxon signed rank test with SPSS program version 12.0. Results: Significant differences were found for the pre and post evaluation of the 'self-management program' for the implementation of tracheostomy care. The development and implementation of the 'self-management program' improved the main caregivers' knowledge of tracheostomy tube management (Z=-3.599, p<.001). Conclusion: Results show that this program has identified an effective nursing intervention for promoting the caregivers' knowledge of tracheostomy care and self-efficacy. We recommend that further research should be done to test primary caregivers' maintenance of knowledge and self-efficacy in tracheostomy tube management and identify factors affecting knowledge and self-efficacy in the care of these patients.

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.
