Although this approach is generally successful, there are several disadvantages, such as occasional scarring of the skin, disruption of the medial canthal ligament, and distortion of the sac in its bony fossa. In addition, there is often extensive bleeding during the procedure. The approach from the nasal cavity has none of these disadvantages and seems more physiologic. In this operation anatomical disturbances are limited to the establishment of a communication between the sac and the nasal cavity. The advantages of this internal approach have long been recognized. Using this method, Jones and Boyden1 have recently reported an extremely high
