만성 기침에 대한 이해 : 신경성 기침을 중심으로

Abstract

Cough is a protective response of the body, and it is one of the most common clinical symptoms of otorhinolaryngology. A chronic cough lasting more than 8 weeks is not uncommon and reduces the quality of life of the patient. Causes of chronic cough include lung diseases such as eosinophilic bronchitis, asthma, and cough variant asthma. And otolaryngologic diseases such as laryngopharyngeal reflux disease or upper airway cough syndrome also cause chronic cough. If chronic cough persists, attention should be paid to laryngopharyngeal reflux disease and upper airway cough syndrome in the view of otorhinolaryngologic aspect. Neurogenic cough should be considered when a cough is induced in a small stimulus with a previous history of upper airway infection and lasts longer than 8 weeks. This study aims to summarize the current knowledge on the pathogenesis, clinical symptoms and treatment of neurogenic cough. (J Clinical Otolaryngol 2019;30:169-175)
