Observations of external ear--an Indian study

Area of Science:

• Anthropology
• Forensic Science
• Plastic Surgery

Background:

• External ear somatoscopy offers insights into ear shape, helix form, Darwin's tubercle, and lobule attachment.
• Such morphological data is crucial for physical anthropologists, plastic surgeons, physicians, and forensic scientists.
• A comprehensive somatoscopic study of ear morphology across the Indian subcontinent is lacking.

Purpose of the Study:

• To document the frequency of various external ear somatoscopic features in adult males and females from central India.
• To provide a detailed somatoscopic analysis of auricle morphology in a specific Indian population.

Main Methods:

• Systematic somatoscopic examination of external ear features in adult males and females.
• Recording the prevalence of traits such as ear shape, helix form, lobule attachment, Darwin's tubercle, and preauricular features.
• Analysis of data to determine the frequency of each somatoscopic feature.

Main Results:

• Oval-shaped ears and normally rolled helixes were the most common features in both sexes.
• Free ear lobules were more prevalent in females, while Darwin's tubercle was more common in males.
• The upper ear edge typically aligned with the eyebrow tail, and the lower edge with the upper lip; preauricular pits and sinuses were rare.

Conclusions:

• The study provides baseline data on external ear morphology in central India, valuable for anthropology and forensic science.
• Observed somatoscopic features can serve as soft biometric traits for personal identification systems.
• External ear somatoscopy aids surgeons in ear reconstruction and physicians in identifying genetic syndromes.
