AbstractSPHINCTER TEARS: Vaginal delivery can lead to tears in the anal sphincters. Total perineal distension following expulsion concerns less than 1% of all deliveries. Initially, sphincter tears generally go unnoticed although echographically detectable defects can be found in one-third of all primiparturients. The inner or outer sphincter may be involved alone or in combination as is seen in half of the cases.
