Anthropometric analysis of the lip–nose complex in bilateral cleft lip infants in North Indian population

Introduction: Bilateral cleft lip deformity necessitates intricate correctional procedures to restore the lip–nose complex. Comparing the anthropometry between different bilateral cleft groups can provide a deeper understanding of these variations. The three-dimensional (3D) digital photogrammetry tool is used to objectively quantify the extent of deformity into mild, moderate, and severe, and thereby predict the postoperative results. Materials and Methods: This prospective observational study was conducted on 22 infants with bilateral cleft lip and 22 age-matched noncleft controls. 3D Photogrammetry using VECTRA 3D Imaging System and VECTRA Analysis Module (VAM) software was done in this study to assess various Lip–nose complex anthropometric parameters in unrepaired bilateral cleft lip patients and controls. Results: There were no significant differences between the case and control groups for age and gender, suggesting adequate matching of the case–control cohort. Our study revealed that Total nasal width, Nasal base width, Subalar or nasal sill width, Alar length, Nasal base width on each side were significantly higher in the case group compared to the control group ( P < 0.05). Nasal projection is significantly less. All the measured lip parameters show significant changes in the case group compared to the control group ( P < 0.05). Conclusion: The use of 3D photogrammetry and VAM software has provided precise measurements that can inform clinical decision-making, objectively categorizing the cleft deformity into mild, moderate, and severe, improving the outcomes, and predicting the result of surgical interventions, postoperative assessment, and a predictor for treatment outcome.
