Objective: Dorsal rat skin flaps are the most commonly used flaps in experimental researches of viability of skin flap. In many studies, modified McFarlane flaps in different sizes have been performed for researching the survival of flaps which are based not only cranially but also caudally. This usage of flaps both cranially and caudally is the biggest obstacle in comparison of the techniques preferred in studies. In order to overcome this problem we designed a study that compares survival of cranially and caudally based flaps.
Material and Methods: We formed two cranially and caudally based flap groups each containing 10 rats. In each rat we designed 11x3 cm sized cranially or caudally based flaps and we compared the survival rates. Survival rates of cranial based flaps were found significantly lower than caudally based flaps (p
