鼻咽喉部各器官位置较深,生理结构复杂,不易直接窥及,须利用特殊的检查设备。软管鼻咽喉镜(包括纤维鼻咽喉镜和电子鼻咽喉镜)检查时病人痛苦小,简单方便,在鼻咽喉部疾病诊断中发挥越来越重要的作用。鼻咽喉镜管径小且可弯曲,光亮度较强,能够直接探入到鼻咽喉腔内,是观察鼻咽喉部表面黏膜情况的最好手段,当怀疑这些部位有异常情况时,均可使用鼻咽喉镜检查来明确诊断,比如:鼻塞、鼻出血、流脓涕,回抽涕中带血;耳鸣、听力下降;咽痛或咽部不适、异物感;吞咽不畅、声嘶等。
Nasopharyngeal larynx organs in deeper, complex physiological structure, not directly peep, to be used special inspection equipment. Hose nasopharyngeal laryngoscope (including fibrolaryngoscope and electronic laryngoscope) examination of patients with small pain, easy and convenient, in the diagnosis of nasopharyngeal laryngeal diseases play an increasingly important role. Nasopharyngeal laryngoscope with small diameter and bendable, strong light, can be directly into the nasopharyngeal larynx, nasopharyngeal laryngeal mucosa is the best way to observe the situation, when suspected abnormalities in these parts, can be used Nasopharyngeal laryngoscopy to confirm the diagnosis, such as: nasal congestion, epistaxis, purulent nasal discharge, transfusion of tears in the blood; tinnitus, hearing loss; sore throat or throat discomfort, foreign body sensation; swallowing poor hoarseness.
