Abstract

Introduction: A multifactorial etiology has been implicated in the development and maintenance of vestibulodynia (VBD), and atrophic changes of the vestibular mucosa have been observed in many patients.

Aim: To assess the vestibular mucosa thickness in patients with VBD by comparing this sample with a control group of healthy fertile women and postmenopausal patients with symptoms of genitourinary syndrome of menopause (GSM).

Methods: Vestibular mucosa thickness was measured with a 20 MHz ultrasound probe (DermaScan C, Cortex Technology, Denmark), including both the epidermis and dermis.

Main Outcome Measures: All women were evaluated by anamnesis, physical examination, and self-report symptoms. Thickness of the vestibular mucosa (expressed in micrometers) was determined by the B-mode, excluding the hyperechogenic entrance echo and hypoechogenic subcutis. Clinical data related to VBD and GSM were recorded using a 0- to 10-point visual analog scale related to dyspareunia and vulvar pain/burning (0 = no pain; 10 = worst possible pain).

Results: A total of 85 patients were recruited: 24 with VBD, 20 with GSM-related symptoms, and 20 matched controls. Vestibular mucosa thickness measurements were not significantly different between the VBD (mean ± DS: 1,092.5 ± 226.1 μm) and GSM groups (1,059.7 ± 221.5 μm), while the parameter was significantly lower (P < .01) than the control group (1,310.6 ± 250.0 μm). Correlation analysis in the VBD and GSM groups between low vestibular mucosa thickness and symptom intensity (burning/pain and dyspareunia) showed a significant correlation.

Conclusion: Patients with VBD have a vestibular mucosa with a lower thickness than healthy women of the same age, with an almost identical value to that found in postmenopausal women. Furthermore, a low vestibular mucosa thickness in the VBD and GSM groups showed a significant correlation with burning/pain intensity and dyspareunia severity.
