一般门诊多用耳镜和鼻镜进行呼吸道检查,用这类方法常不能满意地观察到鼻腔后部、鼻咽部、口咽上下部,下咽部及声门等处的结构。作者设计了一种适于门诊应用的鼻喉纤维镜检查法。鼻粘膜先用血管收缩剂收缩,4％利多卡因喷雾麻醉,即可进行检查。共检查了400名患者,年龄最幼者6岁。277名有阳性发现。阴性结果亦具诊断意义。鼻喉镜检查除可观察隐蔽部位的结构、病变情况和追随观察治疗效果外,也适于作呼吸道激发试验时观察上呼吸道的局部反应性。此外,作者等用此法还诊断了表现为严重哮喘的声带功能性疾患,经心理治疗后,使患者摆脱了药物,哮喘中止,呼吸恢复正常。在作者的病例中,除一例发生轻度鼻衄外,未发生其他并发症。为安全起见,作者主张检查宜在声门水平以上进行,以免诱发喉痉挛。作者等认为此种检 General out-patient use of otoscope and nose for respiratory examination, with such methods often can not satisfactorily observed nasal back, nasopharynx, oropharyngeal up and down, hypopharynx and glottis and other structures. The authors designed a nasal laryngoscopy suitable for outpatient applications. Nasal mucosa with vasoconstrictor contraction, 4% lidocaine anesthesia, can be checked. A total of 400 patients were examined, the youngest being 6 years old. 277 positive findings. Negative results also have diagnostic significance. Rhinopharyngoscopy in addition to the hidden parts of the structure can be observed, the lesion and follow the observation of therapeutic effect, but also suitable for respiratory irritation test observation of the upper respiratory tract local reactivity. In addition, the authors also used this method to diagnose the vocal cord dysfunction manifested as severe asthma. After psychological treatment, the patient was relieved of the drug, the asthma was stopped, and the resumption of normal breathing. In the authors’ case, no other complication occurred except in one case. For safety reasons, the author claims that the examination should be carried out above the glottis level, so as not to induce laryngospasm. The authors think such seizures
