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.

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.

기관의 양성종양은 드물고 증상과 증후가 비슷하므로 대개 기관지 천식으로 잘못 진단된다. 원발성 신경섬유종은 슈반세포(Schwann cell)에서 기원하며 예후는 좋으나 재발할 수도 있고 악성으로 변할 수도 있기 때문에 기관 분절절제와 단단문합술이 권장되어진다. 최근 기관에 발생한 원발성 신경섬유종을 기관 분절절제와 단단문합술로 성공적으로 치험하였기에 문헌고찰과 함께 보고하는 바이다.

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.

서론: 기관내에 발생하는 과오종은 상기도폐쇄를 야기하는 매우 드문 질환이다. 이의 임상상은 기관지 천식이나 만성 기관지염 등의 내과적 질환과 유사하여 진단이 늦어지는 경우가 있다. 증례: 호흡곤란이 주소였던 65세 남자환자에서, 기관내 종괴를 관찰하였다. 종괴는 경직성 기관지내시경을 이용하여 성공적으로 제거되었고, 조직학적 검사상 과오종으로 확인되었다. 이후 환자의 증상은 매우 호전되었다. 결론: 기관내 과오종을 비롯한 여러 종양들은 기도폐쇄를 일으키는 여러 내과적 질환으로 혼동될 수 있다. 그러나 대부분 내과적 치료로는 효과를 기대하기 어렵고 수술적 치료를 요하므로, 이의 감별이 중요할 것으로 생각된다.

Background and Objectives : The treatment of supraglottic stenosis remains a challenging problem in the field of otolaryngology due to its association with dyspnea, dysphagia, and frequent recurrence. Any satisfactory treatment is not yet known. The author experienced six cases of supraglottic stenosis and report the successful treatment of five cases by repeated endoscopic laryngeal excision with KTP-532 laser under suspension layngoscopy. Materials and Methods : Six adults who were treated for supraglottic stenosis between March 1994 and December 1998 at the Department of Otoloaryngology-Head and Neck Surgery, Korea University Medical Center were studied retrospectively. The patients were placed under general anesthesia followed by endoscopic laryngeal excision with KTP-532 laser under supension laryngoscopy. The scar tissue and granulation tissue were visualized with an operating microscope, and then removed using KTP-532 laser (15watts, continuous mode). Intraoperative local steroid(Triamcinolone ) was injected in all cases after the stenotic portions were removed. Results : Endoscopic excision was performed in five cases ; among the five cases, cricoid cartilage was concomitantly removed in two cases, and epiglottis was removed in one case. Satisfactory swallowing and airway respiration were possible in all five patients who underwent endoscopic widening. Conclusion : The treatment of supraglottic stenosis is different from that of tracheal or glottic stenosis in that supraglottic stenosis is mainly developed in membraneous form. Repeated laser excision and local steroid injection under suspension laryngoscopy is an effective and recommend able method for the treatment of supraglottic stenosis.
