Application of ICHD-II Criteria for Headaches in a TMJ and Orofacial Pain Clinic

Abstract

The aim of this study was to identify and diagnose headache in a temporomandibular joint and orofacial pain clinic population using the second edition of The International Classification of Headache Disorder criteria. In 502 temporomandibular disorder and orofacial pain patients, 246 patients (49%) were diagnosed with tension-type headache (TTH), followed by migraine without aura (14.5%), probable migraine (12.9%), migraine with aura (7%), probable TTH (4.8%) and cluster headache (0.2%). The prevalence of headaches was compared between male and female patients, and the prevalence of migraine was found to be higher in women than in men. In evaluating by age, the prevalence of migraine was highest in patients in their 20s and 30s and declined as age increased above 40. TTH showed the highest rate throughout all age groups, but it also decreased as age increased. In this study, the prevalence of migraine was lower than that reported in Dr Kim et al.'s study, and the prevalence of TTH much higher than that reported in the previous study. Of the headache patients, 81.1% presented with masseter muscle pain and 47.8% with temporal muscle pain. This finding suggests that pericranial muscle pain may be an inducing factor of primary headache.
