Can vacuum-assisted delivery cause more vaginal stretching than forceps?
Both vacuum-assisted and forceps deliveries can increase the risk of vaginal stretching compared to spontaneous birth, but forceps are generally associated with a higher risk of trauma and long-term vaginal laxity.
Detailed Medical Explanation
Forceps delivery has a higher association with perineal and vaginal trauma compared to vacuum extraction. However, both procedures may increase the risk of overstretching or damaging the pelvic floor and vaginal muscles, especially if combined with a prolonged pushing phase or large baby. The choice of instrument depends on clinical circumstances. Prompt pelvic floor rehabilitation is important after any instrumental delivery. RCOG Instrumental Delivery Guidance.
Clinical Context
Instrumental deliveries are sometimes necessary for maternal or fetal safety. Individualised care, expert technique, and early postnatal pelvic floor support can reduce long-term risks.
