Abstract

Objectives

The objectives of the present study were to evaluate the efficacy of using butorphanol tartrate after arthrocentesis for management of patients with internal derangement (ID) of temporomandibular joint (TMJ) through clinical study.

Patients and methods

The study included 40 patients who had ID of TMJ stage II or III according to Wilkes classification, who were divided randomly into two equal groups. The study group was treated by arthrocentesis followed by intra-articular injection of 1 mg of butorphanol tartrate, which is equal to 0.5 ml of solution. The control group was treated by arthrocentesis followed by intra-articular injection of 1 ml of sodium hyaluronate.

Results

There was a statistically significant decrease in the visual analog scale, as well as a significant increase in both the maximum mouth opening and the lateral excursion, in the study group compared with the control group, and there was a statistically significant improvement in the study group compared with the control group with regard to clicking sound.

Conclusion

Intra-articular injection of butorphanol after arthrocentesis provides a long-term palliative effect in the clinical study of TMJ ID.
