Under these circumstances we have squamous epithelium buriedin the tissues from 1 to 5 mm. beneath the surface. Alterations of the Continuity of the Vaginal Mucosa Due to Perineal Opera-tions—Where it is necessary to repair the outlet some time after labor, by Fig. 191.—A Blind Right Vagina Communi-cating with a Well-developed RightUterus.

When the edges of the wound are approximated these islands of mucosalie more or less deeply imbedded in the underlying stroma and entirely cutoff from the parent mucosa, thus giving rise tocystic formations under the scar. Relation of the Urethra to the Vagina.—It isvery important to have a clear understanding ofthe relation of the vagina to the urethra, as theyare intimately associated over a considerable dis-tance. Furthermore, as will be seen later, certaincyst-like dilatations arising from the floor of theurethra should not be confused with vaginal cysts,although at first sight they may bear a strikingsimilarity.
