The twin block injection: an adjunctive clinical aid for the management of acute arthrogenous temporomandibular joint dysfunction
Ananthan, Sowmya / Subramanian, Gayathri / Patel, Trishna / Quek, Samuel Y. P.
Background: The twin block Injection is a novel nerve block that has been shown previously to be efficacious in the management of masticatory myofascial pain. Little is known about its effectiveness for reducing pain from the temporomandibular joint (TMJ).
Case report: A 19-year-old man presented with limited mouth opening with pain in the left side of his face. After a thorough history and examination was completed, the diagnosis was acute anterior disc displacement without reduction in the left TMJ and myalgia of the left side temporalis and masseter muscles. After receiving the twin block injection, the patient reported that the pain in his TMJ had reduced along with the concomitant myalgia. The twin block injection is efficacious for the management of both arthrogenous and myogenous sources of temporomandibular disorders.

Keywords: myalgia, nerve blocks, temporomandibular disorder
