Korean Medicine Treatment for the TMJ — A Combined Approach with Acupuncture, Chuna, and Herbal Medicine
Table of Contents
Why combined treatment is needed
Temporomandibular disorder (TMD) involves a combination of internal joint structures (disc, cartilage), surrounding muscles (masseter, temporalis, pterygoids), and psychological factors (stress, anxiety). Treating only one of these is rarely enough for fundamental resolution, so a combined approach that simultaneously applies acupuncture, chuna, and herbal medicine is most effective. TMD treatment at a Korean medicine clinic is typically scheduled as 2–3 sessions per week over a base course of 8–12 weeks.
Acupuncture — pain control and muscle relaxation
The core acupoints in TMJ treatment are Xiaguan (ST7), Tinggong (SI19), and Jiache (ST6).
- Xiaguan (ST7): Located below the zygomatic arch, just above the TMJ. It is the main point for improving intra-articular blood flow and controlling pain.
- Tinggong (SI19): Located just in front of the tragus, in the depression that forms when the mouth opens. Effective for TMJ-related tinnitus and pre-auricular pain.
- Jiache (ST6): Located anterosuperior to the angle of the mandible, on the masseter. It is a key acupoint for masseter hypertonicity and clenching.
Connecting electroacupuncture (2–4 Hz) between Xiaguan and Jiache doubles the muscle relaxation and analgesic effects.
TMJ chuna (joint mobilization + muscle release)
Chuna treatment combines two techniques.
- Joint mobilization: Wearing gloves, the Korean medicine doctor places fingers intraorally and gently distracts the mandibular condyle anteroinferiorly to widen the joint space, creating physical room for the displaced disc to return.
- Myofascial release: The tight fascia of the masseter, temporalis, and lateral pterygoid is released directly from outside the mouth and intraorally. The lateral pterygoid in particular is the key muscle behind anterior disc displacement, so releasing it directly contributes to improving disc position.
Herbal medicine — modified Soshiho-tang
In Korean medicine, the TMJ belongs to the Shaoyang meridian, and Soshiho-tang (Xiaochaihu-tang) is the representative formula for Shaoyang disorders. Bupleurum and Scutellaria release stagnant heat in the liver and gallbladder, while Pinellia and ginger support digestive function. For TMJ pain, Paeonia and licorice are added to relieve muscle spasm; if tinnitus is present, Acorus and magnetite are added. For patients with severe stress-related clenching, Gami-soyo-san is sometimes combined.
Treatment course and prognosis
During the acute phase (first 2–4 weeks of severe pain), treatment is provided 3 times a week, and during the stable phase, the interval is widened to 1–2 times per week. After a total of 8–12 weeks, most patients can expect more than 70% reduction in pain and normalization of mouth opening. Even after treatment ends, ongoing self-directed jaw exercises and stress management are essential to prevent recurrence.
