超声引导关节腔内注射富血小板血浆治疗颞下颌关节紊乱的疗效分析

【摘要】　目的?评估超声引导下关节腔中注射富小板血浆（PRP）治疗颞下颌关节紊乱病的有效性。方法?2016年4月至2018年4月，门诊诊治45例确诊为颞下颌关节紊乱患者，超声引导将采集于患者自身的PRP注射于患者病变的颞下颌关节腔内。观察患者在治疗前和治疗后1、3和6个月的最大张口度，及颞下颌关节在静息、运动和咀嚼时VAS评分。结果?关节腔内注射PRP可有效改善最大口腔开放程度，颞下颌关节在静息，运动和咀嚼时VAS评分与治疗前相比显著降低。结论?超声引导下关节腔内注射PRP可显著改善颞下颌关节紊乱患者的体征和症状。

Ultrasound-guided temporomandibular joint injection of platelet-rich plasma for the treatment of temporomandibular joint disorders

Objective To evaluate the effectiveness of ultrasound-guided temporomandibular joint injection of platelet-rich plasma(PRP)in treating temporomandibular joint(TMJ)disorders.Methods From April 2016 to April 2018,a total of 45 out-patients with proved temporomandibular joint disorders were treated at Out-patient Department of authors’hospital.Ultrasound-guided injection of PRP,which was collected from the patient’s own blood,into the diseased TMJ cavity was performed in all patients.Before treatment and at one,3,6 months after treatment,the degree of maximal mouth opening and the visual analog scale(VAS)scores at resting,exercising and chewing status were determined.Results Intra-articular injection of platelet-rich plasma could significantly improve the degree of maximal mouth opening,and VAS scores at resting,exercising and chewing status could be obviously decreased when compared with preoperative data.Conclusion Ultrasound-guided intra-articular injection of PRP can significantly improve the clinical signs and symptoms in patients with TMJ disorders.
