Neurofibromatosis [Von Recklinghausen`s disease] is a rare Mendelian dominant disease, which shows multiple generalized symptoms and signs at various sites [Ex Skin, Bone, Nerve, Endocrine, Mediastinum rarely Lung, etc.]. We experienced one case of neurofibromatosis which has typical skin lesions [cafe-au-lait, multiple nodules, axillary freckling] with neurofibrosarcoma [malignant change from mediastinal lesion]. Patient was admitted our department because of recently developed severe dyspnea which was probably due to main tracheal compression by mediastinal neurofibrosarcoma. After successful removal of mediastinal mass dyspnea disappeared completely. Patient`s postoperative course was uneventful, and the patient was discharged 14 days after operation.

Substernal goiter may be defined as any thyroid enlargement that has 50 to 100 % of its mass inferior to the thoracic inlet. Ectopic substernal goiters are rare, and most substernal gaiters arise from cervical thyroid gland. Fifteen to fifty percent of these patients are asymptomatic. Symptoms, when present, are usually the result of tracheal or esophageal compression. Symptoms are often positional. Standard chest roentgenograms are often diagnostic, but computed tomographic or radioactive iodine scans may be helpful. In symptomatic patients or those in whom explorations are undertaken for diagnostic purpose or exclude carcinoma, surgical removal is indicated. Although cervical thyroids with substernal extension may be safely and successfully removed through a cervical incision, primary substernal goiters by definition derive their blood supply from within the thorax and are better approached by splitting the sternum or through a posterolateral thoracotomy. Recently we experienced a child fist sized secondary posterior mediastinal goiter in 55-year old female. The mass was completely removed through right posterolateral thoracotomy without any complications. The postoperative courses were uneventful.

Pure lipoma, originating from the trachea is a very rara disease entity A-37-ycar-old-male patient had suf'leered from intermittent episodes of dyspnea and has been treated under the diagnosis of bronchial asthma for 6 months. On chest CT scan and bronchofiberscopic examination, a round mass with the pedunculated neck was found in the mid-portion of the membranous portion of the intrathoracic trachea. Under the guide of fiberoptic bronchoscope, the mass was extirpated using polypectomy w re loop and eletrocauterization . He was discharged without any events on third postoperative day of operation and has been well without recurrence for 6 months.

Adenoid cystic carcinoma of the tracea is rare, but is a very serious critical life-threatening disease.Nearly all the lesions of the trachea are presented as obstructive lesions. Bronchoscopic examination including chest CT, tomogram and air tracheogram are essential for the further definition of these lesions. This is a case report of adenoid cystic carcinoma in a 47 years old male patient. The tumor was located in cervical trachea with wide base and obstructing the lumen almost completely. The patient`s symptom was productive cough and hoarseness for 4 months. The tumor was resected and End-to-End anastomosed. The tumor was confirmed to be adenoid cystic carcinoma histopathologically. The need for removal of tracheal tumor whether complete or incomplete, is clear enough regardless of the histology of the tumor. This patient was treated post-operatively with radiation.

Benign tumors of the trachea are rare and are usually misdiagnosed as bronchial asthma because of the similarity of the symptoms and signs. Although the prognosis of neurofibroma which originats from Schwann cells is good, it may recur or undergo malignant change, so segmental resection of the trachea is recommended. Recently, we experienced a case of primary neurofibroma of the trachea treated successfully by segmental resection of the trachea and end-to-end anastomosis. We report it with a brief review of literatures.

In the past several years the popularity of the motor cycle has produced an increasing incidence of the injuries to the larynx and trachea. Most of all on accidents come to death and survivors to the hospital are rare. Early diagnosis and to keep air way are necessary to initiate proper treatment in injury of upper air way. Meticulous apposition of mucous membrane and reconstitution of laryngeal skeleton are important. We experienced a rare case of 26 year old men with cricothyroidal transection after trauma. On Oct. 17, 1985, the patient struck his neck on baggage frame of truck when dropping from his motor cycle on sudden stop. Emergency tracheal intubation on distal segment of trachea was accomplished by otolaryngologist in a local clinic. He was transferred to our hospital. Exploration 2 hours later revealed complete separation of cricoid cartilage from thyroid cartilage. The recurrent laryngeal nerve could not be identified. Anastomosis of thyroid and cricoid was accomplished and Portex endotracheal tube was inserted as splint for 10 days. No stenosis developed. The air way appeared adequate for moderate physical activity though paramedian fixation of vocal cord paralysis. Postoperative follow-up course has been good after he discharged on POD 14 days.

Bronchogenic cysts are uncommon congenital lesions which are derived from primitive foregut. Most of the bronchogenic cysts may occur at the tracheal bifurcation, both main bronchi, the lung parenchyme and the mediastinum. We experienced a case of bronchogenic cyst with a esophageal stalk. The diagnosis was made by simple chest x-ray and confirmed by bronchoscopy and chest CT. On the chest CT findings, 6.8X4.8 cm-sized oval shaped mass was located on the right posteroinferior side of the carina, elevating the right main bronchus and the thin wall of the mass was enhanced with contrast materials. On the operative findings, the esophagus and the cyst were connected with a stalk and the cyst was filled with mucinous materials. And on the histological findings, the mass was lined with pseudostratified ciliated columnar epithelium. Thus we report this case of bronchogenic cyst with review of literatures.

Tracheoesophageal puncture (TEP) and voice prosthesis insertion following laryngectomy may fail to form an adequate seal. When spontaneous closure of the fistula tract does not occur after conservative measures, surgical closure is required. The purpose of this study was to summarize the available evidence on surgical methods for TEP site closure. A comprehensive search across PubMed, Web of Science, SCOPUS, and Cochrane was performed to identify studies describing surgical techniques, outcomes, and complications for TEP closure. We evaluated the rate of unsuccessful TEP closure after surgical management. A meta-analysis with a random-effect method was performed. Thirty-four studies reporting on 144 patients satisfied inclusion criteria. The overall incidence of an unsuccessful TEP surgical closure was 6% (95% confidence interval [CI] 1-13%). Subgroup analysis showed an unsuccessful TEP closure rate for silicone button of 8% (95% CI < 1-43%), 7% (95% CI < 1-34%) for dermal graft interposition, < 1% (95% CI < 1-37%) for radial forearm free flap, < 1% (95% CI < 1-52%) for ligation of the fistula, 17% (95% CI < 1-64%) for interposition of a deltopectoral flap, 9% (95% CI < 1-28%) for primary closure, and 2% (95% CI < 1-20%) for interposition of a sternocleidomastoid muscle flap. Critical assessment of the reconstructive modality should take into consideration previous history of surgery or radiotherapy. Nonirradiated fields and small defects may benefit from fistula excision and tracheal and esophageal multilayer closure. In cases of previous radiotherapy, local flaps or free tissue transfer yield high successful TEP closure rates. Depending on the defect size, sternocleidomastoid muscle flap or fasciocutaneous free flaps are optimal alternatives.

The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

Background: Tracheal hamartoma is a very rare cause of upper airway obstruction. Its clinical features can mimic medical conditions, such as bronchial asthma, chronic bronchitis, and so on. Case; This report presents the case of a 65 year old man whose major symptom was dyspnea. We found a tumor in his distal tracheal lumen, and the tumor was removed with success using rigid bronchoscope. The tumor was histologically proven to be a hamartoma, and his symptoms were much improved. Conclusion: It is important to distinguish it from other conditions because medical management is often not helpful. Surgical correction-with or without thoracotomy-is inevitable.
