Overlap between orofacial pain and vulvar vestibulitis syndrome.

OBJECTIVES To explore the prevalence of orofacial pain (OFP) among patients with vulvar vestibulitis syndrome (VVS) and to examine the relationship between signs and symptoms of OFP and clinical characteristics of women with VVS, we investigated differences in psychologic characteristics and severity of painful intercourse. METHODS In this cross-sectional exploratory study, 137 women with VVS completed questionnaires that assessed levels of pain, anxiety, somatization, and presence of signs and symptoms suggestive of clinical and subclinical OFP. Demographic data were gathered from medical records. RESULTS OFP was found to be a highly prevalent (78%) condition among women with VVS. Compared with women who had no OFP symptoms (n=30), those with symptoms (n=64) reported higher levels of anxiety (45.0 vs. 37.8, Bonferroni adjusted P=0.017), somatization (125.2 vs. 96.0, Bonferroni adjusted P<0.001), and psychologic distress (62.8 vs. 56.0, Bonferroni adjusted P=0.002). Although we observed a similar trend among women with subclinical OFP (n=43), this trend only reached statistical significance with respect to somatization. Differences were not detected for demographics, duration of pain, and severity of pain during intercourse across the 3 groups. DISCUSSION OFP is a common condition among women with VVS. Because severity and duration of painful intercourse did not differ by OFP classification but psychologic characteristics did, we must begin to question a unidimensional focus on vestibular mucosa as a reason for pain and persistent distress.
