The aim of this study is To compare the accuracy and effectiveness of ultrasound (US) guided autologous blood injection (ABI) versus non- guided technique for the treatment of chronic recurrent temporomandibular joint dislocation
All patients involved in this study will be divided randomly to two different groups and injected with autologous blood into joint space and pericapsular tissue.
Study group (group A) will be injected with autologous blood with ultrasound guidance.
control group (group B) will be injected with autologous blood without US guidance. Anatomical landmarks and tactical sense will be followed only.
The operation will be done under local anesthesia ( Auriculotemporal nerve block ) the skin overlying the temporomandibular joint will be scrubbed by an antiseptic solution and the area will be isolated with sterile towels. External auditory canal will be blocked with cotton.
About 3 ml of blood will be withdrawn from patient's antecubital fossa, of which 2 ml injected intra-articular and 1 ml in the pericapsular tissue (PT) The procedure should be repeated on the opposite side in case of bilateral involvement.
