Several reports have investigated airway obstruction caused by redundancy of arytenoid mucosa. Flexible laryngoscope examination revealed prolapse of the mucosa overlying the arytenoid. Usually, pharyngeal or laryngeal microscopic procedures can successfully treat the redundancy of arytenoid mucosa. We experienced two cases of airway obstruction caused by redundancy of artenoid mucosa and report it with review of literatures.

Pharyngeal and laryngeal foreign bodies are common problem at ENT clinic. Removal of a foreign body is mostly simple with the manipulation of endoscope and various instruments. Rarely, migration of swallowed sharp foreign body makes complication. We describe a 74-year-old patient diagnosed with foreign body in larynx involving thyroid. In this case, we present this disease and the treatment course which has been successfully treated by surgical removal and conservative treatment. Furthermore, we discuss its symptoms, physical examinations through literature review.

Adenoid cystic carcinoma(ACC) is one of the common malignant tumor of the major and minor salivary glands. ACC arising from the larynx is relatively rare(less than 1% of laryngeal malignant tumors) and only about eighty cases have been reported in the English literature. Definite diagnosis of these lesions is made only from a histological analysis, because findings and symptoms are non-specific. The diagnosis progresses very slowly, therefore it often presents at an advanced stage with regional and distant metastasis. Here, we present one case of ACC of the supraglottic region with a review of literature.

Paratracheal air cysts are rare lesions and detected incidentally during CT scan or autopsy. Histopathologic diagnoses of paratracheal air cysts include trachocele, tracheal diverticulum and lymphoepithelial cyst. The cysts are lined by ciliated columnar epithelium and have communication with trachea. Previous reports suggested an association with obstructive lung disease because of increased expiratory pressures in these patients. Most of these cysts are asymptomatic but rarely cause productive cough, wheezing, recurrent laryngeal nerve paralysis and difficult intubation. We report a case of paratracheal air cyst causing dyspnea with a review of literature.

Endotracheal intubation is commonly associated with laryngeal injury that often resolves spontaneously without any complication. However, stenosis or granulomatous lesions are generally found on the tracheal wall or vocal process at the tube cuff level, caused by excessive cuff pressure. We present a case of fatal vocal cord granuloma leading to dyspnea following orthognathic surgery and sustained intubation for 14 hours.

Solitary neurofibroma of the glottis is extremely rare and accounts for only 0.1-1.5% of benign laryngeal tumors. Aryepiglottic fold is the most frequent involved site followed by arytenoids and ventricular folds. There have been few reports of neurofibroma of the true vocal cord. We report a case of neurofibroma which was deeply embedded in the vocal cord and misdiagnosed as muscle tension dysphonia with a review of literatures.

애성이란 음성의 질적 변화를 의미하는 것으로 이는 후두의 가장 대표적인 주 증상이다. 애성의 원인으로는 현재까지 알려져 있는것만 해도 약50 여종이 있다고 하며 그중 virus에 의한 상기도 감염증이 가장 많은 비율을 차지하고 있는 것으로 알려져 있고, 후두결절 및 풀립, 후두마비, 후두암, 후두유두종, 후두결핵등의 순으로 발생하는 것으로 알려져 있다. 최근 저자들은 본원에 입원중인 환자로서 애성 때문에 본 이비인후과로 진찰의뢰된 환자중 비교적 보기드문 질환과 동반된 애성환자 4예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 증예1. 29세 남자로서 교통사고로 후두부에 외상을 입은후 1 달만에 애성이 발생. 후두경 소견상 좌측성대의 paramedian paralysis 및 arytenoid cartilage의 전위가 인정되었음. 증예2. 53세 남자로서 clonorchis sinensis로 일반외과에서 전신 삽관마취하에 choledochostomy를 시행한 6 일후에 애성이 발생. 후두경 소견상 좌측성대의 median paralysis가 인정되었음. 증예3. 56세 남자로서 Aortic Aneurysm으로 내과에 입원한 환자로 입원전 3개월부터 애성이 발생. 후두경 소견상 좌측성대의 intermediate position paralysis 및 arytenoid cartilage의 전위가 인정되었음. 증예4. 74세 남자로서 Bronchogenic Ca.로 내과에 입원중인 환자로 입원 3년전부터 애성이 발생. 후두경 소견상 우측성대의 paramedian paralysis가 인정되었음

Background and Objectives Vocal fold (VF) scar is known to be the most common cause of dysphonia after laryngeal microsurgery (LMS). Steroids reduce postoperative scar formation by inhibiting inflammation and collagen deposition. However, the clinical evidence of whether steroids are helpful in reducing VF scar formation after LMS is still lacking. The purpose of this study is to determine whether intralesional VF steroid injection after LMS helps to reduce postoperative scar formation and voice quality. Materials and Method This study was conducted on 80 patients who underwent LMS for VF polyp, Reinke's edema, and leukoplakia. Among them, 40 patients who underwent VF steroid injection after LMS were set as the injection group, and patients who had similar sex, age, and lesion size and who underwent LMS alone were set as the control group. In each group, stroboscopy, multi-dimensional voice program, Aerophone II, and voice handicap index (VHI) were performed before and 1 month after surgery, and the results were statistically analyzed. Results There were no statistically significant differences in the distribution of sex, age, symptom duration, occupation and smoking status between each group. Both groups consisted of VF polyp (n=21), Reinke's edema (n=11), and leukoplakia (n=9). On stroboscopy, the lesion disappeared after surgery, and the amplitude and mucosal wave were symmetrical on both sides of the VFs in all patients. Acoustic parameters and VHI significantly improved after surgery in all patients. However, there was no significant difference between the injection and control group in most of the results. Conclusion There was no significant difference in the results of stroboscopy, acoustic, aerodynamic, and subjective evaluation before and after surgery in the injection group and the control group.

Methods for the operative management of patent ductus arteriosus are now well established, and in the vast majority of children the circulatory shunt can be safely and effectively abolished by dividing the ductus or by closing it in continuity with ligatures and transfixing sutures. In adults, however, closure of patent ductus arteriosus may pose important technical problems, particularly when there are associated pulmonary hypertension, calcification, aneurysm and infective endocarditis. Under these circumstance, division or ligation is unusually hazardous because the diseased vessels often fracture or tear when sutures are placed in them. Then we closed the patent ductus arteriosus by use of cardiopulmonary bypass in 18 patients and ligated the ductus via thoracotomy in 18 patients from Jan. 1986 to May 1990. And we compared the results between two different methods. We concluded that ligation of ductus had a problem of rupture and transpulmonary internal suture closure of PDA had a problem of injury of recurrent laryngeal nerve.

대상 및 방법: 1981년 3월부터 1996년 7월 까지 본원에서 치험한 원발성 기관 종양은 14례로, 평균 연령은 45.9세 였으며, 남녀비는 1:1.8이였다. 결과: 14례중 9례가 악성이었으며, 선양낭성암이 5례로 가장 많았다. 대부분의 환자에서 단순흉부촬영 및 기관지 내시경, 전산화 단층촬영을 시행하였고 대부분의 종양은 중하부에 위치하였다. 수술적접근을 위해 기관을 편의상 상부, 중부, 하부기관으로 분류하였으며, 각각의 위치에 맞게 경부 칼라절개, 경부 칼라절개 및 부분적 정중 흉골 절개, 우측 개흉술, 그리고 정중 흉골 절개 및 후두 박리술을 시행하였다. 수술후에 문합부위 파열 및 그로인한 기도폐쇄,설골 상부 박리후에 후두부 부종으로 사망한 례가 각각 1례씩 있었으며, 추적관찰중 진단후 8개월만에 사망한 1례를 제외한 전환자는 추적기간중 비교적 양호한 임상 경과를 밟았다.
