Abstract

Abstract text (incl. figure legends and references)

Introduction: Temporomandibular disorders (TMD) is complex and associated with the burden of chronic pain pathologies. Migraine has become one of those constantly found among TMD patients. An association between TMD and migraine has been published. However, no study has reported TMD prevalence according to migraine pain distribution of the somatosensory of the trigeminal nerve (V1, V2, V3). Aim: To investigate the prevalence of TMD with comorbid migraine in Orofacial Pain Clinic, Dental Institute, King's College London Hospital during 2016-2021. Method: The dataset was reviewed for patients diagnosed with TMD during consultation at the OFP Clinic at KCH between January 2016 and December 2021. Data were described by simple statistics, including numbers and percentages. Result: Over five years, we collected data from 1,345 OFP patients. Among 421 TMD patients, 28.26% (n=119) of them presented with comorbid migraine. The majority (94%) had chronic TMD symptoms (duration > 3 months). Myofascial pain was the most prevalent (54.62%), followed by TMD pain due to arthrogenous origin (26.89%). Among TMD patients with comorbid migraine, 60.50% were diagnosed with chronic migraine. Of the TMD patients with migraine, 66.39% suffered from migraine headache (V1 area only), 26.89% suffered from migraine with facial involvement (V1 with V2 and/or V3 area), and 6.72% suffered from orofacial migraine (V2 and/or V3 area). The sole migraine patients were also included in our dataset. Among 242 migraine patients, TMD was found in 57.24% of patients with migraine headache (V1 area only), in 49.23% of patients with migraine with facial involvement (V1 with V2 and/or V3 area), and in 20.51% of patients with orofacial migraine (V2 and/or V3 area). Conclusion: TMD and migraines might commonly occur, especially in individuals with muscle-related chronic TMD and chronic migraine. Although TMD is mostly related to migraine pain in the V1 area, the proportion of TMD with migraine patients reporting pain in the facial region (V2 and/or V3) was not relatively small. Therefore, clinicians should be aware of the presence of migraine headache and orofacial migraine in TMD patients.
