Summary
This study establishes normal ear measurements for males and females, providing crucial data for microtia reconstruction, especially in bilateral cases where standard ear size is unknown.
Area of Science:
- Plastic Surgery
- Anthropometry
- Craniofacial Research
Background:
- Auricular framework creation is vital for microtia reconstruction.
- Current methods rely on contralateral ear size and Nagata theory.
- Data for bilateral microtia reconstruction framework sizing is lacking.
Purpose of the Study:
- Determine mean anthropometric measurements of the external ear.
- Establish normal ear projection values in males and females.
- Compare measurements between sexes and between right/left ears.
Main Methods:
- Measured 524 subjects (96 men, 428 women) aged 17-35.
- Utilized Vernier caliper for precise measurements.
- Recorded total ear height, width, lobular dimensions, and pole measurements for both ears.
Main Results:
- Significant differences in most ear dimensions between males and females.
- Minimal side-to-side differences in dimensions, except female total ear height.
- Significant differences in ear projection between sexes, with some side-specific variations in females.
Conclusions:
- Provides essential baseline anthropometric data for ear reconstruction.
- Findings are particularly relevant for planning bilateral microtia reconstruction.
- Establishes normative data for auricular framework design.
