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.

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.

갑상선 수술 후 발생한 성대마비는 삶의 질을 중요시하는 요즘 시대에 제일 치명적 합병증 중 하나이다. 그 결과 수술 중 신경감시시스템의 사용은 보편화되고 있으나 아직 기존의 시스템은 외과 의사가 사용하기에 불편하거나 문제점들이 있다. 그래서 새로운 방식의 신경 탐침과 신경 감시 장치의 개발이 필요한 시점이다. 이에 최근 모든 수술 기구(금속형 기구, 내시경 및 로봇 기구, 에너지 기반 디바이스)에 탈부착이 가능한 신경을 자극하는 신경 탐침 및 후두 떨림을 측정하기 위한 표면압력센서를 이용한 새로운 형태의 수술 중 신경감시시스템의 개발에 대한 연구가 기대된다.

Neurilemmoma is a relatively rare benign tumor which may be derived from nerve sheath of the peripheral, sympathetic and cranial nerve except the optic nerve and olfactory nerve. And it is a characteristically solitary and well-encapsulated mass. About 25% of neurilemmoma occurs in the head and neck region and the acoustic nerve is most frequently involved, but neurilemmoma of the larynx is rare. Recently, we experienced a case of neurilemmoma occurred in the right aryepiglottic fold of the larynx. The tumor was successfully removed by transoral approach under direct laryngoscope. So we report this case with literature review.

Background and Objectives Injection laryngoplasty is a common method for treatment of unilateral vocal fold paralysis. Unilateral vocal fold paralysis has various causes, including idiopathic, infection, stroke, neurologic condition, surgery and nerve invasion by cancer. To the knowledge of the authors, there was no study on the relationship between the causes of vocal cord paralysis and the outcome of injection laryngoplasty. Therefore, we tried to investigate the difference in the outcomes of injection laryngoplasty between vocal cord paralysis after surgery group and nerve invasion by cancer group. Materials and Method A retrospective analysis was performed for 24 patients who underwent vocal cord injection due to unilateral vocal cord paralysis caused by surgery or nerve invasion by cancer. The objective quality of the voice was assessed by acoustic voice analysis with the Multi-Dimensional Voice Program. Results Both group showed an improvement of fundamental frequemcy (F0), jitter percent, shimmer (percent), and noise to hearmonic ratio (NHR) after injection laryngoplasty. The vocal cord paralysis due to nerve invasion group showed more improvement in both the mean and median value of F0, shimmer percent and NHR than the vocal cord paralysis due to surgery group, but there was not statistically significant. Conclusion Our study did not show a statistically significant difference in outcome between vocal cord paralysis due to cancer invasion group and surgery group, but statistically tendency was suggested. The vocal cord paralysis due to nerve invasion group showed more improvement in both the mean and median value of acoustic voice analysis than surgery group.

Schwannoma, also known as a neurilemmomas or neurinomas, is benign peripheral nerve sheath tumors arising from the Schwann cells. About 25~45 % of all schwannomas are found in the head and neck region, and the majority are found in the parapharyngeal space. Schwannoma of the larynx is very rare with an incidence of 0.1~1.5% in all benign laryngeal tumors. Recently, we experienced a case of a pedunculated schwannoma arising from the left aryepiglottic fold in a 80-year-old patient. The tumor was completely excised under direct laryngoscopy with the use of a $CO_2$ laser and subsequently confirmed as schwannoma. So, we report this case with a review of the literatures.

A non-recurrent laryngeal nerve on the left side is a rare anomaly which is reported in 0.04% and it is associated with abnormal developments of the aortic arch during embryogenesis. Although the possibility is extremely low, it is important to consider the possible existence of a non-recurrent laryngeal nerve to prevent a nerve injury during thyroidectomy. We experienced a 42 year-old male with left thyroid papillary cancer who had right side aortic arch and aberrant left subclavian artery. Even though we found that this patient had a recurrent laryngeal nerve, we present this case of the right aortic arch with an aberrant left subclavian artery variation with a brief review of literature.
