A surgical access assembly includes a sleeve and a port. The sleeve is adapted for insertion within tissue to access an underlying tissue site. The sleeve defines a first passage therethrough. The first passage has a first diameter. The port defines one or more second passages extending therethrough. The port is adapted for insertion within the first passage of the sleeve in a substantially sealed relationship therewith. The one or more second passages are adapted for a substantially sealed reception of a surgical object therethrough. The one or more second passages have one or more second diameters. The port is selectively removably positionable within the first passage of the sleeve. The first diameter is greater than the one or more second diameters.
