The age of the patients ranged from 19 to 46 years. In all cases, the mucoperichondria of the nasal septum were dissected bilaterally from the septal cartilage. The prepared en-bloc costal cartilage graft was mounted onto the caudal portion of the septal cartilage and fixed to the septum with 5-0 polydioxanone sutures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The follow-up duration ranged from 10 months to 2.5 years.
