In this 1-Minute Video, Dr. George Bartley discusses the role of the medial canthal tendon (MCT) during external dacryocystorhinostomy (DCR). In general, he prefers to leave the MCT intact. Staying inferior to the boundary between the MCTs can preclude the rare complication of cerebral spinal fluid leakage. Since the MCT is affixed to bone, securing it appropriately can ensure that the newly created anastomosis will not collapse. Although some believe that skin inclusion can compromise lacrimal pump function, he has not observed this problem.
