Thyroid hematoma secondary to a blunt trauma is a rare problem. Despite the rarity, it can be a life-threatening condition with tracheal compression. Both surgical exploration and conservative management have been suggested for thyroid hematoma. However, there is still controversy on the optimal treatment. A 67-year old man who progressed severe dyspnea and neck swelling was transferred to the emergency department with a blunt anterior neck trauma after traffic accident. Contrast enhanced neck computed tomography scan showed huge hematoma within the right thyroid gland and slight tracheal deviation without prominent airway obstruction. One day later, anterior neck swelling was aggravated and the patient was intubated to prevent airway obstruction. After 3 days, hematoma resolution was revealed and extubation was done. We report this case with a review of literature.

Thymic cysts are uncommon tumors which usually occur in the neck and mediastinum. It is known to arise from embryonic remnants of the thymopharyngeal duct or from infammation of thymic tissues. Patients with thymic cyst are often asymptomatic and identified after surgical removal and histologic examination. We experienced a 73 year-old man with recently developed dyspnea. During the examination, chest CT showed a $5{\times}6cm$ sized cystic mass causing deviation of the trachea. It was located in between the right thyroid gland and anterior mediastinum. It also caused tracheal narrowing noted by bronchoscopy. Right anterior cervical incision and removal of the mass was performed and a histological diagnosis of thymic cyst was confirmed. The patient was discharged without complication.

Pleura, diaphragm, pericardial fat pad, intercostal muscles and omentum can be used to protect and revascularize the bronchial suture line of tracheal transplantation, lung transplantation and pulmonary resection. The purpose of the present study is to compare the influence of the pleura, diaphragm and omentum in survival of isolated tracheal segments in the experimental animals. Material and Method: Sprague-Dawley rats weighing 250- 350g were used. The animals were divided in three groups; the pleura, omentum and diaphragm. Following intraperitoneal anesthesia, endotracheal intubation was performed. Then the trachea was exposed. A three-ring sec- tion of cervical trachea was excised. The resected trachea was implanted at each sites. After 2 weeks, rats were sacrificed. Histopathological examination of the tracheal segments was performed. For comparison of each groups, histopathological viability of resected tracheal segment was scored by three tissue layers; epithelium, submucosa, and cartilage. The results were presented as average score. Result: In histopathological examination, submucosa and cartilage using tracheal segment necrosis scoring system. The pleural group showed well preserved tissue. There was minimal necrosis and inflammation compared with other groups. In the pleural group, tracheal necrosis scores were $2.17\pm0.983$at epithelium, $1.67\pm0.516$ at submucosa and $2.17\pm0.753$ at cartilage. At the omental group, scores were $1.00\pm0.00,\;1.60\pm0.548\;and\;1.80\m0.447$. In the diaphragmatic group, scores were $1.40:\pm0.894,\;2.40\pm0.547\;and\;2.20\pm0.447$. Total necrosis score were $6.00\pm1.789$ in the pleural group, $4.40\pm0.894$ in the omental group and $6.00\pm1.414$ in the diaphragmatic group. Conclusion: There were no significant viability differences in terms of total necrosis score for the viability of resected tracheal segment. But the best result was achieved in the omental group. Therefore, omental wrapping on tracheal graft site will be beneficial for the prevention of graft necrosis.

Background: Common treatment modalities for tracheal stenosis include conservative methods such as repeated balloon dilatation, removal of obstructive material through bronchoscopy and T-tube insertion as well as operative treatment methods. Recent advances in surgical approaches through tracheal resection and end-to-end anastomosis have been reported to give better functional and anatomical results. Material and Method: Between March 1990 and July 2002, 41 patients who received tracheal resection and end-to-end anastomosis at Asan Medical Center, University of Ulsan were studied retrospectively. Result: The causes for tracheal resection and end-to-end anastomosis included 26 cases of postintubation stenosis, 10 cases of primary tracheal tumors (3 benign, 7 malignant), 1 case of endobronchial tuberculosis, 2 cases of traumatic rupture, and 2 cases of tracheal invasion of a thyroid cancer, Of the 41 patients who received tracheal resection and reconstruction, 29 received tracheal resection and end-to-end anastomosis, and 12 received laryngotracheal anastomosis with cricoid or thyroid cartilage resection. Four of these patients received supralaryngeal release. The average length of the resected trachea was $3.6{\pm}1.0$cm. Of the 41 patients who received tracheal resection and end-to-end anastomosis, 30 (73.2%) experienced no postoperative complications, and 8 (19.5%) experienced granulation tissue growth and/or minor infections which improved after conservative management. Good or satisfactory results were therefore achieved in 92.7%. Complications included repeated granulation tissue growth in 7, wound infection in 2, anastomotic site dehiscence in 2, restenosis resulting in dyspnea on exertion in 1, and repeated postoperative aspiration requiring retracheostomy in 1. There was no early postoperative mortality. There were 3 cases of hospital death. Conclusion: In cases of proper length of tracheal lesion, excellent results were obtained after tracheal resection and end-to-end anastomosis. But, granulation tissue growth is so serious complication, it is necessary for continuous study and efforts to prevent it.

Primary adenoid cystic carcioma of trachea is rare, with an incidence of only 0.2 per 100,000 persons per year. When all series of the tracheal carcinomas are combined, adenoid cystic carcinoma is the second most common tumor only to squamous cell carcinoma in incidence. Most patients have wheezing or stridor, dyspnea, hemoptysis, and cough as symptoms. Treatment options include surgery alone, radiation therapy alone, or a combination of both. The recommended surgical option is primary tracheal resection and reconstruction. Recently, we experienced a case of adenoid cystic carcinoma in 45 year old female patient who was treated tracheal tumor resection and end-to-end anastomosis of the trachea, so we report this case with the literatures.

Acquired tracheoesophageal fistula (TEF) can occur rarely from various causes. Recently, cuff-related tracheal injury after endotracheal intubation with the orotracheal tube and tracheostomy cannula is the most common etiology of nonmalignant TEF. Since cuff-related TEF is usually preventable with proper selection of the cuffed tube and close monitoring of cuff pressure. Although most patients present increased secretions, recurrent pneumonia, or coughing after swallowing, a high index of suspicion is required in patients at risk for developing a TEF. Surgical correction for the defectis required. In most cases, primary closure of the esophageal defect and tracheal resection and end-to-end anastomosis give the best results.

Blunt intrathoracic tracheal injuries are rare, even among blunt chest trauma patients. An early diagnosis based on a high index of suspicion allows for timely surgical management of potentially fatal airway trauma, thereby improving overall outcomes. Diagnosing these injuries can be difficult due to their nonspecific clinical features and the occasional difficulty in radiologic diagnosis. If a patient exhibits respiratory compromise with difficult ventilation and poor lung expansion, despite the insertion and management of an intercostal drain following high-energy blunt trauma, there should be a heightened suspicion of potential airway trauma. The aim of primary repair is to restore airway integrity and to minimize the loss of pulmonary parenchyma function. This case report discusses the rare clinical presentation of a patient with blunt trauma to the intrathoracic airway, the surgical management thereof, and his overall outcome. Although blunt traumatic injuries of the trachea are extremely rare and often fatal, early surgical intervention can potentially reduce the risk of mortality.

The increasing frequency of post-tracheostomy stenosis parallels the increase in the incidence of tracheostomy. The development of stenosis of trachea following the operation of tracheal tumor or tracheostomy is a very serious complication. The continuing need for an adequate tracheal substitute has not been answered, despite the necessities of excision and reconstruction of the trachea to keep for effective ventilation. Experimental tracheal reconstuction, with a prosthesis of heavy Marlex mesh and pericardium, _ vas performed in twelve dogs. Five to six tracheal ring circumferential defects were created and were bridged with heavy Marlex mesh fashioned into a tube of suitable diameter. Group A: A prepared cylinder of Marlex mesh was anastomosed outside the cut ends of the trachea. Group B: The external surface of the prepared cylinder of Marlex mesh was completely covered with suitably sized patch of pericardium and overlapped all margin of the Marlex mesh by 2 to 3 mm in each direction. Group C: The internal surface of the prepared cylinder of Marlex mesh was covered with suitably sized patch of pericardium and overlapped all margin of the Marlex mesh by 2 to 3 mm in each direction. The results of this exepriment were as follow: 1. In group A and B, the graft was well bridged with new granulation and fibrous tissue, and the lumen of trachea kept good patency for effective ventilation.. The interstices of Marlex became uniformly infiltrated with young well vasculated connective tissue. Epithelization has not yet occurred at 4 weeks in each group, but there were evidences of new growing mucosa at grafted site in 6 weeks. The remainder of the prosthesis was completely covered with glistening epithelium and the underlying fibrous tissue became more matured with little inflammation. These findings were more striking in group B than group A. 2. In group C, the covered pericardium was necrotized with stenosis of the lumen of grafted site due to poor blood supply.

Tracheobronchial rupture is one of the less-common injuries associated with blunt chest trauma. The diagnosis of tracheobronchial rupture is not easy, but failure to diagnosis may lead to death or long-term disability. Early diagnosis and appropriate management can reduce the mortality and morbidity. Bronchoscopy is the diagnostic method of choice for patients with tracheobronchial rupture. We report a case of tracheal rupture after blunt chest trauma. A 40-year-old man was transferred to our hospital for dyspnea after blunt chest trauma. He was promptly diagnosed as tracheal rupture by fiberoptic bronchoscopy and chest computed tomogram. He was successfully managed by thoracotomy and primary repair.

Post-intubation tracheoesophageal fistula is rare, and its management causes a serious problems to surgeons. We have experienced 4 cases in 3 patients. Simple ditcision and closure of the fistulas were done by trans-cervical approach after weaning of ventilator. The tracheal defect was closed by simple suture, and the esophageal defect was closed in two layers before a viable muscle flap was interposed between the two suture lines in order to prevent recurrence. There was one delayed tracheal stenosls and one recurrent fistula, and these complications were also managed success ully.
