Objectives: We evaluated the stability of the comorbidity between vulvodynia and orofacial pain (OFP) and its associated clinical characteristics over a two-year follow up period.
Methods: In an earlier study of vestibulodynia patients, we administered questionnaires assessing demographic data, self-reported pain, anxiety, somatic awareness, and presence of signs and symptoms suggestive of clinical and subclinical orofacial pain (OFP). The present study readministered the same surveys to a subset of the original cohort after a two-year follow up period.
Results: Of the 138 women in the previous study, 71 (51%) agreed to participate in the present study. We confirmed our earlier findings that (1) orofacial pain is a highly prevalent (66%) condition among women with vestibulodynia, and (2) compared to women with no OFP symptoms, those with OFP symptoms experience higher levels of anxiety (P=0.005), and somatic awareness (P<0.001). While OFP symptoms showed improvement in many of the vestibulodynia patients (33%) with OFP symptoms at baseline, 13% had either developed new symptoms or transitioned from subclinical to clinical OFP classification. Intercourse-related pain decreased in 69% of patients and increased in 24% of patients. Consistent with our earlier report, we did not observe significant differences with respect to demographics or severity of pain during intercourse among the subgroups.
Discussion: Orofacial pain is a common comorbidity among women with vestibulodynia, although the presence of OFP can vary over time. The comborbidity between vestibulodynia and OFP suggests that common underlying mechanisms may mediate both conditions.
