Background
Foetal head malposition
Foetal head malposition is closely related to vaginal delivery failure and maternal-foetal morbidity during operative vaginal delivery [Ultrasonic diagnosis of the foetal head position is more accurate than transvaginal digital examination [Traditional methods require the identification of the anterior and posterior fontanelles to determine foetal head position, which can be difficult for residents. Our research team proposed a simplified method for determining foetal head position that may help residents master this skill in a relatively short time. We consider the frontal suture to be the key to distinguishing the anterior and posterior fontanelles. Therefore, we performed a pilot comparison study to examine the effects of the new teaching method in improving the diagnostic accuracy of the foetal head position.
