New methods for specialized subjective and high-precision objective evaluation of constricted ears: A pilot study

Area of Science:

• Plastic Surgery
• Otolaryngology
• Medical Imaging

Background:

• Current methods for evaluating constricted ears lack specificity, comprehensiveness, precision, and predictive power for surgical outcomes.
• Accurate assessment is crucial for effective diagnosis and treatment planning in pediatric ear conditions.

Purpose of the Study:

• To develop and validate a personalized, subjective evaluation scale for constricted ears.
• To introduce novel objective indices using digital methods for precise ear evaluation.
• To enhance the accuracy of diagnosing and predicting surgical outcomes for constricted ears.

Main Methods:

• A personalized subjective scale was administered via telephone to parents 3-6 months post-surgery.
• 3D scanning captured ear geometry before and 14 days after surgery.
• Key ear dimensions (VHA, MLH, LIA) were calculated using Mimics software, with statistical analysis via Wilcoxon signed-rank test.

Main Results:

• High patient satisfaction scores were reported, with ear folds and helix receiving the highest subjective ratings.
• Objective measurements showed significant differences between preoperative constricted ears and normal ears (P < .05).
• The new digital indices demonstrated greater precision and reliability compared to existing methods.

Conclusions:

• The developed subjective scale provides a comprehensive and personalized assessment of constricted ears.
• Novel objective indices and digital measurement techniques offer superior accuracy and reliability for evaluating treatment efficacy.
• These advancements facilitate improved patient management and informed treatment selection for constricted ears.
