从《内经》探讨耳聋病机

Analysis on Disease Mechanism of Deafness According to Internal Canon

《内经》关于耳聋的论述散见于各个篇章,对其病因病机有着较全面的记载。通过收集梳理《内经》有关耳聋条文,发现耳聋的发病与脏腑和经络病变密切相关,耳聋病机可分为两个方面:1脏病致聋,肾、肝、脾、肺四脏病变均可导致耳聋,肾、脾、肺所致耳聋多为因虚致聋,肝病所致耳聋则包括虚、实两个方面,且情绪失常导致耳聋多与肝相关。2经病致聋,头为诸阳之会,胆足少阳经、大肠手阳明经、小肠手太阳经、三焦手少阳经与耳聋的发生有着密切的关系,经病致聋主要因外感引起,实者居多。

Discussions on deafness could be found in various chapter in Internal Canon,and the cause and mechanism are fully explored. After reviewing the entries on deafness in Internal Canon,it could be found that internal organs and meridians are closely associated with deafness,and the mechanism includes two aspects：1Diseases of the internal organs cause deafness. Diseases of kidneys,liver,spleen and lung all can cause deafness. Usually kidneys,spleen and lung cause deafness of deficient syndrome,while liver cause deafness of deficient and excessive syndromes,and deafness due to abnormal emotion is often associated with liver. 2Meridian disease could cause deafness. The head is the location for the convergence of yang meridians. The gallbladder channel of foot shaoyang,the large intestine channel of hand yangming,the small intestine channel of hand taiyang and the tri-jiao channel of hand shaoyang have a close relationship with deafness. Deafness caused by meridian is mainly related to exogenous pathogenic factors,and usually is excessive.
