Abstract
Introduction: Nasal embryological development anomalies have an estimated prevalence of 1 in 20,000 to 1 in 40,000 live births, typically of genetic, syndromic, or non-syndromic origin. Alar cartilage defects may be overlooked during preoperative evaluation, often presenting as incidental findings during surgery. Methods: Two cases of alar cartilage agenesis and hypoplasia in different locations are reported, diagnosed intraoperatively during open septorhinoplasty, and reconstructed using costal cartilage grafts. Discussion: Congenital nasal anomalies are rare and poorly described in the literature. Their aesthetic and functional impact may be minimal, making preoperative identification challenging. Unexpected intraoperative findings require modification of the reconstructive plan during surgery. Conclusion: Comprehensive preoperative assessment, including photographic documentation by trained personnel, targeted palpation of the alar cartilage, and evaluation of nasal contour, is recommended to facilitate early detection of these anomalies and optimize surgical outcomes.
