All patients underwent primary repair using the Fisher technique. Group I received customized nasal conformers fabricated using digital models, while Group II did not. Anthropometric measurements, including nostril height and width, columella deviation angle, and nasolabial angle were used to assess nasal symmetry between both groups.
