Perineoplasty (also perineorrhaphy) denotes the plastic surgery procedures used to correct clinical conditions (damage, defect, deformity) of the vagina and the anus.

[1] A person who experiences painful sexual intercourse (dyspareunia), or who is afflicted with vaginismus (involuntary contraction of the puboccygeus muscles) can be treated with a variant perineoplasty procedure that loosens the over-tight vaginal introitus (entry).

Some surgeons use a simple surface incision at the fourchette for such loosening, but generally is not the most effectively corrective surgical approach.

Perineoplasty is generally considered effective for treatment of dyspareunia,[6] including that caused by lichen sclerosus,[7] and vaginismus.

[6] It is also considered an effective treatment for vulvar vestibulitis, although it is generally recommended following the failure of nonsurgical methods.
