Biopsy
Multiple cadaveric vaginal outlet wall biopsies were obtained in the V-shape from the superior to the inferior edge of the vaginal outlet wall. The excisional V-shape biopsies were carried out from the sulcus between the posterior-distal vaginal wall and the vaginal outlet wall and continued to the sulcus between the vaginal outlet wall and the labia minora. Neither the vaginal wall nor the labia minora was included in the excision specimen—the excisional biopsies between 7 and 8 o’clock were used for the histological examinations in the present study.
