Abstract： This article is to introduce the clinical experience of Professor WANG Bangcai in the treatment of sudden deafness. Professor WANG believes that the fundamental pathogenesis of sudden deafness is the reversal counterflow of internal qi and disturbance of qi movement in the ear orifice，and the direct factors leading to its onset are the invasion of wind pathogens and emotional disorder. In clinical diagnosis and treatment，it is urgent to remove the triggering factors，treat by dispersing wind and cold， diffusing the lung and unblocking the orifices，soothing the liver and resolving constraint，and invigorating blood and dissolving stasis. Later， it is advisable to regulate the overall qi mechanism， apply medication according to syndrome differentiation， and adjust the physical constitution to prevent diseases. Thus can eliminate pathogens and restore the healthy qi，achieving significant effects quickly.
