Although endoscopic endonasal repair is the current standard of care, data on long\u2010term functional outcomes and factors associated with revision surgery remain limited. This study evaluates clinical characteristics, surgical outcomes, and predictors of relook surgery following endoscopic endonasal CCA repair using mucosal flaps without stenting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective single\u2010center study was conducted including children (\u2264\u200918\u2009years) who underwent unilateral or bilateral CCA repair at a tertiary referral pediatric hospital, between 2015 and 2025.

Postoperatively, granulation tissue, synechiae, and restenosis occurred in 22%, 33%, and 39% of cases, respectively, resulting in a relook surgery rate of 47%, most commonly within the first postoperative month.
