A cadaveric analysis of the efficacy of blind injections into the lateral pterygoid muscle.

Background: Temporomandibular disorders (TMD) are amongst the most common causes of orofacial pain. Hyperactivity of the lateral pterygoid muscle (LPM) is associated with the pathological mechanisms associated with TMD. Botulinum Toxin-A (BTX) injections into the LPM can be used as a treatment for TMD; however, a lack of clinical standardisation for this procedure can lead to adverse outcomes, especially when using anatomical landmark-based approaches.

Botulinum toxin A for the management of temporomandibular myofascial pain: A cohort study.

Myofascial pain represents the largest subgroup of temporomandibular disorders (TMD) that account for a common cause of non-dental orofacial pain. The management of TMD is complex due to the chronic nature of the condition, alongside acute episodes presenting to the clinician. A fundamental part of TMD management is consideration of the biopsychosocial element in its aetiology.
