ObjectiveShield grafts are widely used in rhinoplasty to improve nasal tip projection, definition, and overall aesthetic harmony. However, objectively assessing their contribution remains challenging. This study aimed to evaluate the aesthetic impact of shield graft application using the Integrated Nasal Tip Aesthetic Score (INTAS), a multidimensional scoring system combining objective measurements, patient-reported outcomes, and independent observer evaluations.MethodsThe dataset of 60 rhinoplasty patients was generated for methodological demonstration. Variables included demographic characteristics, graft material, INTAS scores, Rhinoplasty Outcome Evaluation (ROE) scores, blinded evaluator assessments, patient satisfaction, and postoperative complications. Preoperative and postoperative outcomes were compared using paired statistical analyses. Furthermore, multivariable regression models were used to identify the anatomical predictors that most strongly correlated with improved aesthetic scores after graft placement. The results indicated a statistically significant improvement in overall aesthetic metrics across the cohort, with specific graft dimensions showing a strong correlation with enhanced nasal tip definition. ResultsThe mean age of the cohort was 28.9 ± 7.4 years. Significant improvements were observed in all aesthetic outcome measures. INTAS total scores improved from 22.6 ± 5.3 preoperatively to 46.2 ± 4.8 postoperatively (p
