顳下頜關節沖洗術 - 微創治療Arthrocentesis – minimal invasive treatment

顳下頜關節沖洗術只限於源自關節性的牙骹痛患者上，若患者

是單純的肌肉痛便不會用到此治療。醫生會在顎關節放入兩枝

針，然後用生理鹽水沖洗關節，旨在把發炎物質和纖維組積沖

走減低關節負壓力，亦可注入透明質酸潤滑關節。

Arthrocentesis can only be applied to TMJ dysfunction and is not

applicable to the patients with muscle pain only. Procedure

involves application of two small needles near the TMJ, and the

joint will be washed thoroughly with Normal Saline with the aim to

clear the inflammatory substances and fibrous adhesions, and to

reduce negative pressure of the joints. Lubrication with the

injection of hyaluronic acid may be an additional option.
