UTSW study shows that cellphone images could alter the appearance of the nose and chin:
Selfies taken at 12- and 18-inch distances distort facial features compared to clinical-quality photos taken at 5 feet, a factor that could be driving up requests for plastic surgery.
Cellphone "selfies" distort facial features, an effect that may be driving an uptick in requests for plastic surgery, UT Southwestern researchers show in a new study. The findings, reported in Plastic & Reconstructive Surgery, highlight an unexpected consequence of social media and the need for plastic surgeons to discuss this phenomenon with their patients.
"If young people are using selfies as their only guide, they may be coming to plastic surgeons to fix problems that don't exist except in the world of social media," said study leader Bardia Amirlak, M.D., Associate Professor of Plastic Surgery at UT Southwestern.
Dr. Amirlak explained that patients increasingly use photographs they've taken with a smartphone camera to discuss their goals with a plastic surgeon. There's a documented relationship, he added, between the increase in selfie photographs and an increase in requests for rhinoplasty -- or surgery to alter the appearance of the nose -- particularly among younger patients. However, because cameras can distort images, especially when photographs are taken at close range, selfies may not reflect an individual's true appearance.
To investigate how selfies might alter appearance, Dr. Amirlak and his colleagues worked with 30 volunteers: 23 women and seven men. The researchers took three photographs of each person -- one each from 12 inches and 18 inches away with a cellphone to simulate selfies taken with a bent or straight arm, and a third from 5 feet with a digital single-lens reflex camera, typically used in plastic surgery clinics. The three images were taken in the same sitting under standard lighting conditions.
The selfies showed significant distortions. On average, the nose appeared 6.4% longer on 12-inch selfies and 4.3% longer on 18-inch selfies compared to the standard clinical photograph. There was also a 12% decrease in the length of the chin on 12-inch selfies, leading to a substantial 17% increase in the ratio of nose-to-chin length. Selfies also made the base of the nose appear wider relative to the width of the face. The participants' awareness of these differences was reflected by how they rated the photos when compared side by side.
Carrie McAdams, M.D., Ph.D., Associate Professor of Psychiatry at UT Southwestern and a member of the Peter O'Donnell Jr. Brain Institute, noted that these distorted images can have a lasting impact on how selfie takers see themselves.
"Adolescents and young adults are expected to develop a stable sense of self-identity, a neurodevelopmental process related to making comparisons of oneself with others. Unfortunately, selfies emphasize the physical aspects of oneself in making those comparisons and have been associated with lower self-esteem, lower mood, and increased body dissatisfaction," she said. "Many changes in our society, including selfies, social media, and isolation from COVID-19, have led to escalating rates of mental health problems in this age group, including depression, anxiety, addiction, and eating disorders."
Because the images were taken with one brand of cellphone, Dr. Amirlak suggested that future research should investigate how prevalent this phenomenon is across different phones.
"As the popularity of selfie photography increases," the study authors concluded, "it is crucial to understand how they distort facial features and how patients use them to communicate."
Other UT Southwestern researchers who contributed to this study include Mark P. Pressler, Mikaela L. Kislevitz, and Justin J. Davis.
