후두기능의 전기생리학적 특징에 대한 관심은 1940년대부터 시작되어 1950년대와 1960년대에는 유럽 및 일본에서 Faborg-Anderson, Hirano 등이 후두근전도의 임상적 적용에 대해서 보고한바 있으며, 1970년대부터는 미국에서도 Bleir, Miller등이 후두근전도의 임상적 역할에 대해 보고하고 있다 이와 같이 후두근전도가 임상에 도입된 지 오래되었고 신경후두학 분야에서 후두근육의 전기생리상태를 알 수 있는 아주 중요한 진단도구이나 아직까지 후두근전도는 양적인 평가가 가능한 표준화된 검사는 아니고 내시경이나 방사선학적 검사처럼 경험이 있는 의사에 의해 판독되어지는 검사로 음성장애가 있는 모든 환자에서 집단검진(screening test)으로 이용될 수 있는 검사도구는 아니다. 후두근전도가 임상에서 유용하게 이용되고 있는 질환은 성대운동 장애와 연축성 음성장애이다. 최근 성대운동 장애에 대한 다양한 수술방법이 개발되면서 수술 방법 및 시기 결정, 예후측정에 후두근전도의 이용이 필수적이 되었으며 또한 연축성 음성장애 환자에서 어떤 후두 근육에 botulinum toxin을 주사할 지를 결정하는 데 이용하고 있다. 이번 강의에서는 위 두 가지 질환을 중심으로 후두근전도의 임상적 유용성을 살펴보기로 하겠다.

Over the last 30 years or so, it has been recognized that neurologic disorders could impair laryngeal function, and that neurogenic etiology could be discerned frequently. This has led collaborations between laryngologists and neurologists and focus on the management of neurogenic dysfunction of the larynx and pharynx, including central and peripheral disorder. The author introduced anatomical structure, nerve distribution and neurophysiology of the larynx for understanding its basic functions. The symptoms, diseases from laryngeal dysfunction and the development of diagnosis and management were also discussed.

Inflammatory myofibroblastic tumor (IMT) is a rare benign tumor, that is composed of myofibroblastic spindle cells with inflammatory cells. IMTs usually occur in lungs, intestine organs, orbits and paranasal sinuses, however, it may rarely be seen in the larynx. We present two cases of patients with laryngeal IMT that had different causes and prognosis.

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.

An understanding of the history of laryngology is both interesting and useful for those in the field so this study attempts to uncover some of the interesting aspects of its history. The oldest reference of laryngology in the Orient is in the medical documents called the "Whangjainaekyung",(황제내경) which was written over a time period between 3000-4000 B.C., and described the laryngeal function of respiration, protection of the airway and phonation. In the West, a drawing that seems to portray a tracheostomy was found in medical tombs in the plains of Saqqara in Egypt. These drawings date from approximately 3600 B.C. A watershed in laryngology occurred when a spanish music professor named Manuel Garcia in first successfully used a mirror to inspect the larynx. Since that time, laryngology has developed relatively quickly and clinical laryngology made it possible by means of a number of favorable developments. Great advances in laryngological diagnosis and treatment has occurred since the 1970s thanks to improvements in technology leading to the introduction of an operating microscope, endoscopes and lasers. Despite our recent advances in laryngology, we still have not achieved uniformly favorable outcomes and there is much that we do not know. Our future promises continued advances in the field of laryngology such as gene therapy to improve wound healing and tissue engineering to allow the recreation of normal mucosa. In this review, I divide the history of the larynx into the past, present and future. In the last section, I described the history of laryngology in Korea briefly.

후두낭종은 후두소낭의 비정상적인 팽창으로 발생하는 드문 질환이다. 후두낭종의 크기와 증상에 따라 치료 방법은 단순 경과관찰에서부터 흡인, 경화제 주입, 수술적 치료까지 다양하다. 수술적 치료는 외적 접근법, 내시경적 접근법 또는 두 접근법을 혼용한 접근법을 통해 이루어진다. 최근 저자들은 경부 외적 접근법 및 연골막하 절제를 통한 혼합 후두점액낭종 1예의 치료를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Indications of fiberoptic laryngeal laser surgery (FLS) procedure have broadened by the development of flexible fiberoptic endoscopes and flexible laser systems. FLS procedure performed under local anesthesia and it is the unique value of FLS. The surgery can be performed on patients who are impossible to undergo general anesthesia and difficult to be exposed by laryngeal microsurgery. Main indication of FLS procedure was small to moderate sized hemorrhagic vocal polyp, but we experienced a case of huge vocal polyp with difficult laryngeal exposure treated by FLS procedure under local anesthesia. The vocal polyp was removed successfully without vocal fold scar through fiberoptic laryngeal laser surgery under local anesthesia.

Pyogenic granuloma is one of the benign vascular neoplasm. The nomenclature is misnomer because pyogenic granuloma is not related to infection and granuloma. It represent histopathologically lobular capillary hemangioma. It is most commonly occurred on skin followed by oral cavity such as gingiva, lip, tongue and buccal mucosa. Herein, we report a extremely rare case of pyogenic granuloma which was developed on larynx of a 81 year-old male with review of literature.
