Abstract：This paper introduces the clinical experience of WAN Quanqing in using acupotomy and Chinese medicine to treat temporomandibular joint disorder syndrome. WAN believes that temporomandibular joint disorder syndrome belongs to the category of impediment syndrome in Chinese medicine，which is mostly caused by chronic strain，imbalance of muscles and bones as well as qi stagnation and blood stasis. Modern medicine believes that joint instability is an important cause of temporomandibular joint disorder syndrome， and the etiology and pathogenesis of the disease are analyzed from the perspective of "balance of muscles and bones". Therefore，in WAN’s treatment，muscles and bones are paid with equal attention and the blood is invigorated and collaterals are unblocked. Wan modifies Yiqi Huoxue prescription in his treatment， and uses acupotomy to loosen local adhesion and treat both the interior and the exterior， which exerts great therapeutic effect.
