Investigation of Anthropometric Measurements of Anatomic Structures of Orbital Soft Tissue in 102 Young Han Chinese Adults

Purpose: The aim is to measure and investigate the anatomic structures of orbital soft tissue and the relationships between the adjacent regions in 102 normal young Han Chinese adults using a computer-assisted photography system to provide reference data for periocular cosmetic and reconstructive surgery. Methods: A random sample of 102 Han young Chinese adults (53 males and 49 females) aged from 18 to 25 years in Changsha, Hunan Province, was obtained. Standard digital images were taken and then processed using Image-Pro Plus 6.0 software. The linear and angular measurements, including intercanthal distance, outer canthal distance, palpebral fissure width (PFW), palpebral fissure height (PFH), orbit height (OH), upper lid height, lower lid height, nasal eyebrow height, central eyebrow height, temporal eyebrow height, reference line to lateral canthus'inclination of palpebral fissure, were measured. The proportional indices, including intercanthal distance/outer canthal distance, PFH/PFW, PFH/OH, OH/PFW, upper lid height/OH, lower lid height/OH, nasal eyebrow height/OH, central eyebrow height/OH, and temporal eyebrow height/OH, were investigated. Results: Means and standard deviations of all the items had been obtained and differences between male and female subjects were assessed. Conclusions: The normal measurement values of anatomic structures of orbital soft tissue and the proportional indices for normal young Han Chinese adults provided reference data for periorbital cosmetic and reconstructive surgery.
