“…[16][17][18] While previous work has defined a medium smile angle as a key component of a successful smile, increasing the smile angle was a desirable change in our female study population. 19,20 For aesthetic facial specialists, these results are a reminder to exercise caution when performing injectable neurotoxin procedures that may result in decreased smile excursion. It is also worth discussing the gender differences highlighted by these findings: females were found to significantly increase their smile angle while males did not.…”

The use of filters and editing tools for perfecting selfies is increasing. While some aesthetic experts have touted the ability of this technology to help patients convey their aesthetic goals, others have expressed concerns about the unrealistic expectations that may come from the ability for individuals to digitally alter their own photos in these so-called “super-selfies.” The aim of the study is to determine the changes that individuals seek when enhancing selfies. Twenty subjects participated in this study between July 25 and September 24, 2019. Subjects had two sets of headshots taken (neutral and smile) and were provided an introduction on the use of the Facetune2 app. Subjects received a digital copy of their photographs and were asked to download the free mobile app. After 1 week of trialing the different tools for enhancing their appearance, subjects submitted their self-determined most attractive edited photographs. Changes in marginal reflex distance (MRD) 1 and 2, nose height and width, eyebrow height, facial width, skin smoothness, skin hue, and saturation as well as overall image brightness were recorded. Paired two-tailed t-test was used to evaluate pre- and post-facial measurements. There were no statistically significant changes identified in the analysis of the altered photos in neutral expression. Analysis of all smiling photographs revealed that subjects increased their smile angle (right: +2.92 mm, p = 0.04; left: +3.58 mm, p < 0.001). When smiling photographs were assessed by gender, females were found to significantly increase their MRD2 (right: +0.64 mm, p = 0.04; left: +0.74 mm, p = 0.05) and their smile angle (right: +1.90 mm, p = 0.03; left: +2.31 mm, p = 0.005) while also decreasing their nose height (−2.8 mm, p = 0.04). Males did not significantly alter any of the facial measurements assessed. This study identifies the types of changes that individuals seek when enhancing selfies and specifies the different aspects of image adjustment that may be sought based on a patient's gender.

“…To our knowledge, this is the first open‐source data set for facial palsy. We used the dataset to automatically assess perceived emotion across the spectrum of facial palsy utilizing a newly developed facial emotional recognition algorithm (Affdex) rather than relying on layperson assessment . Although we did analyze the dataset utilizing existing facial palsy evaluation systems, including those based on the clinician perspective (eFACE, House‐Brackmann, Sunnybrook), these grading systems are subjective and fail to capture communicated emotion .…”

Objectives: Facial palsy causes variable facial disfigurement ranging from subtle asymmetry to crippling deformity. There is no existing standard database to serve as a resource for facial palsy education and research. We present a standardized set of facial photographs and videos representing the entire spectrum of flaccid and nonflaccid (aberrantly regenerated or synkinetic) facial palsy. To demonstrate the utility of the dataset, we describe the relationship between level of facial function and perceived emotion expression as determined by an automated emotion detection, machine learning-based algorithm.Methods: Photographs and videos of patients with both flaccid and nonflaccid facial palsy were prospectively gathered. The degree of facial palsy was quantified using eFACE, House-Brackmann, and Sunnybrook scales. Perceived emotion during a standard video of facial movements was determined using an automated, machine learning algorithm.Results: Sixty participants were enrolled and categorized by eFACE score across the range of facial function. Patients with complete flaccid facial palsy (eFACE <60) had a significant loss of perceived joy compared to the nonflaccid and normal groups. Additionally, patients with only moderate flaccid and nonflaccid facial palsy had a significant increase in perceived negative emotion (contempt) when compared to the normal group.Conclusion:We provide this open-source database to assist in comparing current and future scales of facial function as well as facilitate comprehensive investigation of the entire spectrum of facial palsy. The automated machine learning-based algorithm detected negative emotions at moderate levels of facial palsy and suggested a threshold severity of flaccid facial palsy beyond which joy was not perceived.

“…Corneal damage and difficulties regarding food manipulation and oral continence can be the consequence [ 15 – 23 ]. FNP also affects the patients psychologically, and this can cause a decrease in self-esteem, reduction of quality-of-life (QoL), anxiety, and depression [ 15 – 23 ]. The impact of a FNP on a patient’s life is enormous.…”

e-Health and telemedicine implementation in facial paralysis: challenges and pitfalls

et al. 2021

During the current Covid-19 pandemic, a lot of changes had to be made in the care of patients with facial nerve paralysis (FNP). FNP is a life-changing condition with effects on both physical (both esthetic and functional) and psychological aspects of the patient’s life. Telemedicine could be a suitable alternative in the therapy for these patients, since it is often not possible to travel to outpatient clinics or to have normal face-to-face appointments with treating physicians because of pandemic restrictions. This review provides an overview of the current literature in the treatment of FNP during the pandemic and the role of telemedicine/e-Health. Secondly, we will discuss the challenges and pitfalls of implementing e-Health and telemedicine applications in clinical practice. Level of evidence: Not ratable
