Perineal injury after vaginal delivery is common, affecting up to 90% of women. Perineal trauma is associated with both short- and long-term morbidity, including persistent pain, dyspareunia, pelvic floor disorders, and depression, and may negatively affect a new mother’s ability to care for her newborn. The morbidity experienced after perineal injury is dependent on the type of laceration incurred, the technique and materials used for repair, and the skill and knowledge of the birth attendant. After all vaginal deliveries, a systematic evaluation including visual inspection and vaginal, perineal, and rectal exams is recommended to accurately diagnose perineal lacerations. Optimal management of perineal trauma after vaginal birth includes accurate diagnosis, appropriate technique and materials used for repair, providers experienced in perineal laceration repair, and close follow-up. In this article, we review the prevalence, classification, diagnosis, and evidence supporting different closure methods for first- through fourth-degree perineal lacerations and episiotomies. Recommended surgical techniques and materials for different perineal laceration repairs are provided. Finally, best practices for perioperative and postoperative care after advanced perineal trauma are reviewed.
