| Abstract | ||
| Aim This research aims to compare the efficacy of ultrasound (US) guided autologous blood injection (ABI) to the non-guided approach in chronic recurrent temporomandibular joint (TMJ) dislocation. Patients and methods Twenty eligible patients with chronic TMJ dislocations were randomized equally into two groups. Ten patients (study group) received ABI under US guidance, while the remainder (control group) received ABI without guidance. They were clinically assessed for pain intensity using VAS at intervals of two weeks, three-months and six-months after injection. And radiographically after 6 months of injection by double lateral TMJ radiograph in open and closed position regarding the relation of condylar head to the articular eminence in wide mouth opening. Results The mean pain score remains high in study group after 3 and 6 months of intervention compared to control group but there was non-significant difference between groups either pre - operatively, after 2 weeks, 3 months and after 6 months of intervention. At the end of 6 months follow up, In the study group, the condylar head was still displaced anterior to the articular eminence in wide mouth opening in 9 patient . In control group, the condylar head of all 10 patients was still moved anterior to the articular eminence in wide mouth opening. Conclusion Although US -guided ABI is a minimally invasive procedure that involves radiation-free exposure, real-time vision of needle advancement and could afford accurate access to the joint cavity, it was not more successful than the conventional technique and produces more postoperative pain. | ||
