Influence of the nasolabial subunit on visual sensitivity: a preliminary study / 中华医学美学美容杂志

ABSTRACT

Objective:To explore the sensitivity of the normal population to nasolabial subunits.Methods:From 2016 to 2017, we took frontal photos of 25 (20 to 40 years old) people with basically normal nasolabial subunits in West China Hospital of Stomatology. The lip subunits were adjusted at 1.1, 1.2, and 1.3 times magnification or translation to obtain photos of different degrees of malformation of the nasal and lip subunits. A total of 189 young healthy people [96 males, 93 females; age (20.00±1.32) years old] without correction surgery and no maxillofacial deformities were selected to judge the facial aesthetic visual effect of their vision on the nasolabial subunit.Results:The peak sensitivity of nasolabial subunits is the nostril symmetry and columella deviation followed by lip symmetry.Conclusions:Young healthy people have high aesthetic visual effects on nostril symmetry and nasal column translation facial translation, average facial visual effects on lip symmetry and the lowest facial aesthetic visual effects on lip peak symmetry.
