Summary

Intra-articular injections of hyaluronic acid (HA) or platelet-rich plasma (PRP) have been used with temporomandibular joint (TMJ) arthrocentesis to improve lubricative properties and influence regenerative processes. A randomized, controlled clinical trial investigated the benefits of complementary bioviscosuplementation (HA+PRP) in patients submitted to double-portal TMJ arthrocentesis.

Interventions

PROCEDURE

Double-puncture TMJ arthrocentesis under local anaesthesia

The first puncture involved carefully palpating the lateral rim of the glenoid fossa. A 5-cc syringe was prepared with a mixture of 3 cc of Ringer lactate and 1.8 cc of lidocaine with epinephrine. A 21-G needle connected to the syringe was gently inserted into the TMJ skin area. Once the needle tip made contact with the posterior slope of the eminence of the upper joint compartment, it was oriented vertically to access the upper compartment, allowing the surgeon to perform a validation step. For the second puncture, the joint was maintained at maximum distention with continuous inflow through the first portal, while the surgeon felt insufflation/distention in the anterior joint area. The second portal was established using a 21-G needle with successful fluid outflow. After completing an effective circuit, joint washing was carried out using intra-articular hydraulic pressure with at least 150 ml of Ringer lactate solution.
