目的 了解鼻咽癌 (nasopharyngealcarcinoma ,NPC)患者耳部症状及其中耳压力的临床意义。方法 调查160例 ( 3 2 0耳 )确诊为NPC患者的耳部症状、体征并测量中耳压力。结果 以耳部症状首诊的有 75例 ( 83耳 ) ,占总人数的 46 9% ,占总耳数的 2 5 9% ;62耳有分泌性中耳炎 ,占总耳数的 19 4% ;2 1耳有耳部症状而无分泌性中耳炎者 ,其平均中耳压为 -87 62mmH2 O ;全组能作有效测量的 2 40耳的平均中耳压为 -4 9 5 6mmH2 O。结论 耳阻塞感、耳鸣和听力下降等耳部症状是NPC常见临床表现之一 ,发生的原因是中耳高负压 ,严重的中耳高负压者常有分泌性中耳炎发生。因此 ,在NPC高发区 ,对单侧或双侧有上述耳部症状者需警惕NPC的发生
Objective To investigate the clinical significance of ear symptoms and middle ear pressure in patients with nasopharyngeal carcinoma (NPC). Methods 160 patients (320 ears) were diagnosed as otitis media patients with symptoms and signs of ear and middle ear pressure. Results 75 cases (83 ears) were the first diagnosis of ear symptoms, accounting for 46.9% of the total number of ears, accounting for 25.9% of the total ears. 62 ears had secretory otitis media, accounting for 19.4% of the total ears. The mean otolaryngeal pressure was -87 62 mmH 2 O in 21 ears with otitis media but without secretory otitis media; and the mean middle-ear pressure in 2 40 ears for the whole group was -4 9 5 6 mmH2O. Conclusions The ear symptoms such as ear obstruction, tinnitus and hearing loss are one of the common clinical manifestations of NPC. The reason is the high negative pressure in the middle ear and the frequent occurrence of secretory otitis media in the severe middle ear with high negative pressure. Therefore, in the high incidence area of NPC, one or both of the above-mentioned ear symptoms need to guard against the occurrence of NPC
