Superficial cervical plexus block on pain control in patients with temporomandibular joint internal derangement with headache: a retrospective cohort study.
Abstract
Temporomandibular disorders (TMDs) are a group of disorders with varied pathophysiology and clinical manifestations. Masticatory and cervical motor systems have a functional relationship. Superficial cervical muscles have greater hyperactivity in myogenous and mixed TMDs than in healthy individuals, demonstrating an abnormal pattern of contraction. This study aimed to demonstrate the effects of superficial cervical plexus block (SCPB) anesthesia during arthrocentesis in patients with temporomandibular joint (TMJ) internal derangement and headache.
