放大喉镜在鼻咽部检查中的应用

目的 评价放大喉镜在鼻咽部检查中的应用价值.方法 对耳鼻咽喉科就诊的6774例患者施行放大喉镜下鼻咽部检查,连接影像工作系统记录图像文字资料,可疑病变在放大喉镜或鼻内镜直视下取活检.结果 患者对放火喉镜的耐受率98.9%(6700/6774)明显优于间接鼻咽镜30.9%(2095/6774),差异有统计学意义(X~2=6872.75,P＜0.005).放大喉镜可清晰呈现鼻咽部多种病变,能及早发现可疑病变.615例曾分别用纤维鼻咽镜(192例)及鼻内镜(423例)检查显示鼻咽部隆起,放大喉镜检查发现其中418例双侧对称,表面光滑,未见异常,经病理检查证实为正常组织;其他197例于放大喉镜下也显示为鼻咽部隆起,经病理检查证实为各种良恶性病变.结论 放大喉镜检查光亮度强,分辨率高,能早期发现鼻咽部病变,诊断准确率和活检阳性率较高,对鼻咽部疾病诊断具有重要价值.

Clinical applications of magnifying laryngoscopy on nasopharyngeal examination

Objective To evaluate the usability of magnifying laryngoscopy for the diagnosis of nasopharyngeal diseases.Methods An analysis was made on the nasopharyngeal figure and letter data among 6774 cases undergone magnifying laryngoscopy.Among these cases,biopsy would be given to those with suspected lesion in the nasopharynx carried out under magnifying laryngoscopy or endoscope.Results Compliance of patients to magnifying laryngoscopy at the rate of 98.9%(6700/6774)was superior to indirect nasopharyngoscopy 30.9%(2095/6774).The difference was statistically significant(X~2=6872.75,P＜0.005).Magnifying laryngoscopy could clearly show a variety of diseases in nasopharynx,early detection of suspicious lesions.Among 615 cases,both fiber nasopharyngoscopy(192 cases)and nasal endoscopy(423 cases)with nasopharyngeal uplift were used,magnifying laryngoscopy found 418 cases bilateral symmetry,the surface smooth,no abnormal.The pathological examination confirmed normal tissue.Other 197 cases in the larger laryngoscopy also showed the uplift in nasopharynx by pathologically examination confirmed a variety of benign and maligant lesions.Conclusions Magnifying laryngoscopy with strong brightness,high resolution,can early detect the nasopharyngeal lesions,increase the diagnostic accuracy rate and biopsy-positive rate.Therefore,it is valuable for the diagnosis of nasopharyngeal diseases.
