CT‐MCA was evaluated before and after surgery on the external nasal valve using the 'lateral crus pull‐up' procedure (LCPU). The outcomes of CT‐MCA were compared with other currently available objective tests for nasal valve patency.</p> </sec> <sec id="coa12243-sec-0002" sec-type="section"> <title>Study design</title> <p>Prospective cohort study.</p> </sec> <sec id="coa12243-sec-0003" sec-type="section"> <title>Methods</title> <p>This study included 34 patients undergoing surgery on the external nasal valve with the use of the LCPU technique.
