Abstract:
1. A method for soft tissue augmentation wherein said method comprises the injection of cylindrical pellets, wherein said pellets have a hollow conduit running therethrough, wherein said cylindrical pellets are injected in a location where augmentation is desired such that, upon placement of the pellets in the desired location, capillaries or fibrous tissue grow into the hollow conduits thereby preventing migration of the pellets, wherein said pellets are made from an inert physiologically non-reactive material; and wherein the pellets are smooth, have an outer diameter of 100 μm to 500 μm, an inner diameter of 50 μm to 300 μm, a length of 300 μm to 500 μm, a maximum ratio of inner diameter to outer diameter of 0.9 and are sufficiently uniform in dimension so that the pellets cannot nest one inside another; and wherein said method is used to correct velopharyngeal insufficiency.
