I.はじめに
喉頭は気道として上気道と下気道の接点に位置し,消化管としての咽頭,食道などの隣接臓器と密接な関連性があり,その機能としては,呼吸作用,発声作用,嚥下作用などがある。したがって喉頭における病変は,呼吸困難,喘鳴,嗄声,嚥下障害,嚥下痛,喉頭異常感など種々の症状を引き起こす可能性がある。中でも喉頭蓋に病変がある場合には,嚥下に関連した症状を訴えることが多い。
今回我々は,喉頭蓋に主病変があり,嚥下に伴う種々の障害を来した症例をいくつか経験したので,若干の考察を加えて報告する。
Lesions in the larynx cause a variety of symptoms such as dyspnea, stridor, hoarseness, dysphagia, pain during swallowing and an abnormal sensation in the throat.
Diseases with primary lesion at the epiglottis, in particular, frequently cause dysphagia, which may be as mild as to be felt as an abnormal sensation in the throat or as severe as inability to swallow. It occasionally and rapidly progress to a serious condition such as dyspnea, and it is necessary to describe the laryngeal findings completely, institute a suitable treatment, and observe the course carefully.
We described 6 cases with primary lesion located at the epiglottis, i.e., inflammatory epiglottic edema, acute epiglottitis, epiglottic abscess, laryngeal tuberculosis, epiglottic cyst and laryngeal cancer.
