Evidence suggests that medial pterygoid muscle plays an important role in temporomandibular pain. Therapeutic approaches targeting this muscle are needed.
To determine if a solid needle accurately penetrates the medial pterygoid muscle during the application of dry needling.
A cadaveric and human descriptive study.
Needling insertion of the medial pterygoid was conducted in 5 fresh cadaver and 5 subjects with temporomandibular pain. Needling insertion was performed using a 40 mm needle inserted at the inferior angle of the mandibular bone. The needle was advanced from an inferior to superior direction into the medial pterygoid to a maximum depth of 30 mm. In cadavers, medial pterygoid placement was assessed by observation after resecting the superficial overlying tissues. In patients, medial pterygoid placement was assessed by self-reported pain referral during insertion.
Accurate needle penetration of the medial pterygoid was observed in all fresh cadavers and pain referral was reported by 4/5 patients during needling insertion.
Results from both cadavers and patients support the assertion that needling of the medial pterygoid can be accurately conducted.
有证据表明翼内肌在颞下颌疼痛中起重要作用。需要针对该肌肉的治疗方法。
确定在进行干针治疗时，实心针是否能准确穿透翼内肌。
尸体和人体描述性研究。
在 5 具新鲜尸体和 5 名颞下颌疼痛患者中进行翼内肌的针刺插入。使用 40 毫米的针从下颌骨的下角插入，从下到上方向将针插入翼内肌，最大深度为 30 毫米。在尸体中，通过切除表面覆盖的组织后观察来评估翼内肌的位置。在患者中，通过插入时针刺时的自我报告的疼痛放射来评估翼内肌的位置。
在所有新鲜尸体中均观察到准确的翼内肌针穿透，在针刺插入过程中，有 4/5 的患者报告有疼痛放射。
尸体和患者的结果均支持这样的观点，即可以准确地进行翼内肌的针刺。
