Webbed skin of the posterior labial commissure: A rare cause of dyspareunia: A case report.

RATIONALE: Dyspareunia is a common disease affecting the physical and mental health of individuals. There are several reasons for dyspareunia. It is essential to identify the causes of dyspareunia and to implement targeted treatments.

PATIENT CONCERNS: The patient was a 26-year-old married woman who presented with dyspareunia lasting for several months, and never successfully engaged in sexual intercourse. She had a webbed skin with a scar at the posterior labial commissure from the 5 o'clock position to the 7 o'clock position of the vaginal opening, partially blocking it.

DIAGNOSES: This case presented a rare cause of dyspareunia.

INTERVENTIONS: In this case, we designed a five-flap method to extend the skin length of the vaginal opening and solved the problem of obscuration of the patient's vaginal opening.

OUTCOMES: After surgery, the vaginal opening appeared normal, with an apparent increase in diameter, and the incision was recovered.

LESSONS: In this case, we attempted a five-flap plasty on the webbed skin of the posterior labial commissure, and the outcome was satisfactory. This demonstrates the potential of this new treatment. This case report can help clinicians broaden their treatment options.
