A surgical access apparatus having a liner base including: an inner member for insertion through an opening within body tissue for positioning within the body； a sleeve connected to the inner member and extending therefrom through the opening within the body tissue, the sleeve defining a passageway therethrough； an upper ring connected to the sleeve； and a plurality of tensioning elements connected to the inner member and associated with the sleeve to impart a tensioning effect on the sleeve； and an access housing for positioning outside the body and defining a longitudinal axis. The access housing includes first and second elements, the second element connected to the tensioning elements and adapted for rotational movement relative to the first element to cause the tensioning elements to displace the inner member toward the access housing and to cause the sleeve to engage and retract tissue defining the opening within the body.
