Background: We assessed the recovery of 2 face transplantation patients with measures of complexity during neuromuscular rehabilitation. Cognitive rehabilitation methods and functional electrical stimulation were used to improve facial emotional expressions of full-face transplantation patients for 5 months. Rehabilitation and analyses were conducted at approximately 3 years after full facial transplantation in the patient group. We report complexity analysis of surface electromyography signals of these two patients in comparison to the results of 10 healthy individuals.
Methods: Facial surface electromyography data were collected during 6 basic emotional expressions and 4 primary facial movements from 2 full-face transplantation patients and 10 healthy individuals to determine a strategy of functional electrical stimulation and understand the mechanisms of rehabilitation. A new personalized rehabilitation technique was developed using the wavelet packet method. Rehabilitation sessions were applied twice a month for 5 months. Subsequently, motor and functional progress was assessed by comparing the fuzzy entropy of surface electromyography data against the results obtained from patients before rehabilitation and the mean results obtained from 10 healthy subjects.
Results: At the end of personalized rehabilitation, the patient group showed improvements in their facial symmetry and their ability to perform basic facial expressions and primary facial movements. Similarity in the pattern of fuzzy entropy for facial expressions between the patient group and healthy individuals increased. Synkinesis was detected during primary facial movements in the patient group, and one patient showed synkinesis during the happiness expression. Synkinesis in the lower face region of one of the patients was eliminated for the lid tightening movement.
Conclusions: The recovery of emotional expressions after personalized rehabilitation was satisfactory to the patients. The assessment with complexity analysis of sEMG data can be used for developing new neurorehabilitation techniques and detecting synkinesis after full-face transplantation.

A full-face contouring using micro-autologous fat transplantation (MAFT)-gun technique in Vietnamese population.
J Plast Reconstr Aesthet Surg

Plastic and Reconstructive Aesthetic Surgery Center, Vietnam National Burn Hospital, Vietnam Military Medical University, Hanoi, Vietnam.
Article Synopsis
- The study investigates the micro-autologous fat transplantation (MAFT)-gun technique for delivering fat to enhance facial contours, involving 31 participants treated between January 2021 and June 2023.
- Results showed specific fat volume needs for different facial areas, with an overall high satisfaction rate of 83.9% and no reported complications.
- The MAFT-gun technique is deemed safe and effective, significantly improving facial aesthetics and satisfaction even after a year post-surgery, suggesting closed-system fat processors as beneficial alternatives.
Exploring the efficacy of laser speckle contrast imaging in the stratified diagnosis of rosacea: a quantitative analysis of facial blood flow dynamics across varied regions.

Background: Rosacea has a high incidence, significantly impacts quality of life, and lacks sufficient diagnostic techniques. This study aimed to investigate the feasibility of laser speckle contrast imaging (LSCI) for measuring facial blood perfusion in patients with rosacea and to identify differences in blood flow among various facial regions associated with different rosacea subtypes.
Methods: From June to December 2023, 45 patients were recruited, with 9 excluded, leaving 36 subjects: 12 with erythematotelangiectatic rosacea (ETR), 12 with papulopustular rosacea (PPR), and 12 healthy controls.
Delta waves as a sign of cortical plasticity after full-face transplantation.

Faculty of Medicine, Department of Neurology, Akdeniz University, Antalya, Turkey.
This study focused on detecting the reflections of healing and change in cortex activation in full-face transplantation and lesions patients on EEG activity. Face transplant patients have facial lesions before transplantation and, to identify pre-face transplant patients' brain activity in the absence of pre-transplant recordings, we used data obtained from pre-transplant facial lesion patients. Ten healthy, four facial lesion and three full-face transplant patients participated in this study.

Article Synopsis
- - Vascularized composite allografts (VCAs), particularly of the face, can suffer from chronic rejection, which occurs over long periods and is not fully understood, as shown by the evaluation of a VCA removed after 88 months.
- - The study revealed that donor-derived CD8-positive T cells infiltrate the graft's arteries, leading to damage in recipient-derived endothelial cells, contributing to arteriosclerosis.
- - Advanced proteomic analysis identified specific proteins linked to activated T cells and macrophages along with pathways related to artery hardening, suggesting a chronic rejection mechanism driven by T cell responses and the graft's vascular environment.
