Introduction: The aim of this study was to identify risk factors for poor perineal outcome (higher order laceration or wound breakdown) after operative vaginal delivery.

Methods: A retrospective cohort study was performed including all operative vaginal deliveries during 2016. Multiple gestations and failed operative deliveries were excluded. Analysis was performed with Chi-square test, T-test and a multivariate logistic regression analysis.

Results: Our cohort included 334 operative vaginal deliveries (70.7% vacuum and 29.3% forceps) and was on average 32.1 ± 4.7 years old and 87.1% were nulliparous. Fifty-four (16.2%) had a higher order perineal lacerations and 7 (2.1%) had a wound breakdown (1 of which occurred after a higher order laceration). The only significant risk factor for a higher order laceration was chorioamnionitis (aOR 2.3; 95% CI 1.1-5.0). Risk factors for perineal wound breakdown included episiotomy (4.2% vs. 0.9%; p=0.01), type of operative delivery (6.1% after forceps vs. 0.4% after vacuum; p
