Abstract:
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.
