The Efficacy of Platelets Rich Plasma Injection in the Superior Joint Space of the Tempromandibular Joint Guided by Ultra Sound in Patients with Non-reducing Disk Displacement.
OBJECTIVE
The objective of this study was to determine average improvement during the rest and active mouth opening after ultrasound guided platelets rich plasma injection in the tempromandibular superior joint space for the patients complaining from non-reducing disk displacement.


PATIENTS AND METHODS
Thirty-four patients with non-reducing disk displacement underwent guided ultrasound injection of platelet rich plasma to the upper joint space. The extent of maximal mouth opening, chewing efficiency, sound intensity of the TMJ, and tenderness of the TMJ and the masticatory muscles at rest, motion and mastication were thoroughly assessed at the beginning of the study and scheduled for next follow-up at 1st, 3rd, and 6th months.


RESULTS
Injection with platelets rich plasma was significantly more effective in improvements of the extent of maximal mouth opening, statistics result demonstrated a significant reduction in the VAS values of pain at rest, motion and mastication compared to the baseline VAS values.


CONCLUSION
PRP injection to the upper temporomandibular joint space provided improvement in signs and symptoms of patient with non-reducing disk displacement of the temporomandibular joint.
