The bony outlet is found on the roof of the meatus at itshighest point, about the junction of the anterioi two fourths of theline of insertion of the turbinate. The bony and membranousoutlets do not always correspond. If they do, the opening is widewith a clearly defined edge; usually, however, the membranouscanal stretches beyond the bony, running under the mucosa toopen lower down, often in a slit, but sometimes ending blindly witha lateral slit as the outlet.
