Abstract

Background: Temporomandibular disc displacement is a widely faced clinical condition and the management options are vast with varying difficulty and success rates. This study aims to evaluate the use of Botulinum Toxin injection and dextrose prolotherapy for such cases.
Methods: 20 joints were included in this study divided into 2 groups; Group 1 receiving 25% 3mL Dextrose injection (with local anesthetic and saline solution) into the retrodiscal region while group 2 received 35 U Botulinum Toxin – Type A injection in the lateral pterygoid muscle. Pain (according to the visual analogue scale), clicking and maximal interincisal opening were assessed preoperatively and at 4 months followup.
Results: The results showed no statistically significant differences between the 2 groups. The click disappeared in 7/10 joints in group 1 and 9/10 in group 2. The maximal interincisal opening was regained and slightly increased in all participants of the study. All patients reported better pain scores at the end of the followup period.
Conclusions: Within the limitations of this study, we conclude that both treatment options tested are considered acceptable in the management of TMJ anterior disc displacement with reduction. Moreover, the results do not allow recommending one over the other as no statistically significant differences were found.
