Angiomyolipoma is a benign tumor that is composed of adipose tissue, blood vessels and smooth muscle. The kidney is the most common location of this tumor. In the larynx, angiomyolipoma has been rarely reported in the literature. We describe the patient of 64-year-old male with an angiomyolipoma arising from the vallecula. The tumor had a smooth surface with numerous small vessels and showed heterogeneous contrast enhancement on CT. The tumor was not adhesive to surrounding tissue and was completely removed by laryngomicrosurgery with $CO_2$ laser. Microscopically, the tumor is composed of mature adipose tissue, tortuous thick walled blood vessels and thick bundles of smooth muscle.

Pharyngocutaneous fistula is one of the most common wound complications after total laryngectomy. The leakage of saliva may cause an erosion of greater vessels nearby and result in a life-threatening bleeding. 65-year-old male received laryngectomy and pharyngectomy followed by Latissimus dorsi flap reconstruction due to recurred laryngeal cancer with oropharyngeal extension after postoperative radiotherapy. Pharyngeal fistula was developed and an excessive fresh blood flowed through the oral and nasal cavity. The patient was transferred to the operating room immediately, and the causing artery was ligated. The rupture of the common carotid artery and its branches should be warned when the pharyngocutaneous fistula is developed. Prompt and proper therapy must be performed for the patients with impending or acute hemorrhage.

It is well known that laryngeal papilloma is histopathological benign, but clinically one of the most troublesome disease in otolaryngologic department, usually seen in child age. Since Cleesmann reported papilloma of the vocal cord, 1817 first, the etiology had not been known exactly. The symptoms in children are dyspnea, dysphonia due to recurrence, and papilloma in adult can change into neoplasm. The papilloma is thought as real neoplastic lesion and there is not effective treatment, using now repeated removal and combined therapy. This report is based on the typical findings and progress of one case of laryngeal papilloma observed for the past 13 years with repeated removal and topical application of 5-FU at our department. Authors have experienced this subject is interesting that the change of the tumor region during the course than to any new therapeutic methods employed, and so report with some reviews of the literatures.

후두 악성종양의 치료로서 후두전적출술을 시행하는 경우 환자는 의사 전달수단인 언어의 장애를 동반하게 된다. 후두전적출술후 언어장애를 해결하기 위해 여러종류의 음성재활법이 제시되어 만족할 만한 결과를 얻고 있으나 그중 식도발성은 대부분의 학자들이 인정하는 가장 추천할 만한 방법이지만 시간이 걸리고 배우기가 어려워 환자들이 쉽게 단념할 수 있다는 단점이 있다. 저자들은 후두전적출술을 받은 10명의 환자에서 인두식도분절을 fluoroscopy로 관찰하여 다음과 같은 결과를 얻었기에 보고하는 바이다. 1) 식도발성을 잘하는 예에서는 pseudoglottis의 전후길이가 좌우길이보다 길었고 식도발성을 못하는 9례에서는 좌우길이가 전후길이보다 크거나 길었다. 2) 식도발성을 못하는 9례중 7례에서 인두식도 분절을 관찰할 수 있었다. 3) 인두식도분절에서 pseudoglottis의 모양이 식도발성을 잘하는 예에서는 정상성대와 유사하게 나타났다. 4) 식도발성을 잘하는 예에서는 pseudoglottis의 위치가 윤상인두괄약근 상방 2cm부위에서 관찰되었으며 식도발성을 못하는 9례중 6례에서는 pseudoglottis의 위치가 윤상인두괄약근 위치였으며 2례에서는 pseudoglottis가 각각 윤상인두괄약근상방 1cm, 1.5cm에 있었다.

Inverted papilloma is a rare benign tumor which usually arises from sinonasal mucosa. We experienced a case of 62-year-old male who presented with foreign body sensation in throat. A round mass was found at right false vocal cord in laryngoscopic examination. It was excised in laryngeal microsurgery. The pathologic diagnosis was inverted papilloma of false vocal cord. Recurrence or complication did not occur during the follow up period of three months.

Although many factors associated with difficult intubation have been known, predictors of difficult mask ventilation are not well known. We experienced a case of nearly complete airway obstruction following usual anesthetic induction which needed various emergency treatments. The patient had a preoperative diagnosis of contact granuloma of right posterior vocal cord and bilateral vocal cord palsy but later was found out as invasive laryngeal cancer. Upon the surgical field of view, both vocal cords were showing significantly thickened and fixated appearance and was considered as in the critical narrowing state with the potential of complete obstruction. Using $C-MAC^{(R)}$ video laryngoscope we were able to see the narrowed vocal cord and choose proper size of endo-tracheal tube. Consequently, intubation was successfully done and operation was conducted. From this case, we have lessons that physicians should examine the patient's airway more carefully in case of laryngeal mass and prepare emergency measures.
