Volumetric analysis of cleft lip deformity using 3D stereophotogrammetry

Area of Science:

• Plastic Surgery
• Craniofacial Surgery
• Medical Imaging

Background:

• Cleft lip presents unique challenges in nasolabial area reconstruction.
• Accurate volumetric assessment is crucial for evaluating surgical outcomes.
• 3D stereophotogrammetry offers advanced capabilities for morphological analysis.

Purpose of the Study:

• To quantify and compare pre-operative and post-operative volumetric changes in the upper lip tissues of patients with cleft lip.
• To assess the efficacy of surgical interventions through 3D morphological analysis.
• To establish a baseline for volumetric variation in cleft lip patients.

Main Methods:

• An anthropometric study utilizing 3D stereophotogrammetry on twenty facial images from ten subjects.
• Quantitative analysis of nasolabial area morphology, comparing pre- and post-operative states.
• Statistical analysis using Student's t-test to determine the significance of volumetric changes (p < 0.01).

Main Results:

• A consistent increase in upper lip volume was observed in all patients post-surgery.
• The average increase in upper lip volume was approximately 29.7%.
• Significant differences (p < 0.01) were found between pre-operative and post-operative measurements, indicating substantial volumetric adjustments.

Conclusions:

• 3D stereophotogrammetry is a valuable tool for detailed pre-operative evaluation and accurate post-operative outcome assessment in cleft lip surgery.
• The study provides a quantifiable measure of upper lip volumetric variation following surgical correction.
• The findings highlight the technique's utility in understanding and improving surgical results for cleft lip patients.
