Regenerative treatments for scleroderma in cutaneous manifestations of the face: a systematic review.

OBJECTIVES: Scleroderma is a heterogeneous chronic autoimmune disease affecting connective tissue, characterised by chronic inflammation and fibrosis, particularly affecting internal organs and skin. Orofacial involvement is common, leading to facial atrophy, mask-like appearance and difficulties in function that significantly impact patients' quality of life. This systematic review evaluates different autologous regenerative treatments of facial manifestations of scleroderma, aiming to provide comprehensive understanding of their effectiveness in reducing fibrosis, and thereby improving function and skin quality. METHODS: A search in PubMed, Embase, Web of Science Core Collection, Cochrane CENTRAL, and CINAHL was conducted. Studies assessing autologous regenerative treatments in cutaneous manifestations of the face in scleroderma patients were included. Outcomes of interest were treatment characteristics, characterisation of biomaterials, outcome measurements and patient satisfaction. Methodological quality was assessed with the Effective Public Health Practice Project tool. RESULTS: In total 18 studies were included. Methodological quality of studies was weak (n=15) and moderate (n=3). Treatments consisted of autologous fat grafting, platelet-rich plasma, stromal vascular fraction, and adipose-derived stem cells. In general, most studies showed improvements of symptoms, but no treatment was considered superior. CONCLUSIONS: Autologous regenerative treatments hold potential for alleviating cutaneous manifestations of the face in scleroderma. Further clinical trials should be well-designed to improve the quality of clinical evidence.

Assessing Facial Palsy: Does Feedback Improve Assessment Using the eFACE and Sunnybrook Facial Grading System?

OBJECTIVE(S): To explore learning effects when applying the clinician-graded electronic facial function scale (eFACE) and the Sunnybrook Facial Grading System (Sunnybrook). METHODS: Surgeons, facial rehabilitation therapists, and medical students were randomly allocated to the eFACE (n = 7) or Sunnybrook (n = 6) and graded 60 videos (Massachusetts Eye and Ear Infirmary open-source standard set); 10 persons with normal facial function and 50 patients with a wide variation of facial palsy severity. Participants received an introduction and individual feedback after each set of 10 videos. Scores were compared to the reference score provided with the set. Multilevel analysis was performed to analyze learning effect. RESULTS: A learning effect was only found for the eFACE, with significant difference scores in set 1 and 2 compared to set 6, and no significant difference scores in the following sets. The difference score was associated with the reference score (severity of facial palsy) for eFACE (ß = -0.19; SE = 0.04; p < 0.001) and Sunnybrook (ß = -0.15; SE = 0.04; p < 0.001). Age of participants was also associated with the difference score in the eFACE group (ß = 0.18; SE = 0.03; p < 0.001). No differences in scores were found between groups of participants. CONCLUSION: The eFACE showed a learning effect of feedback while the Sunnybrook did not. LEVEL OF EVIDENCE: NA Laryngoscope, 134:3105-3111, 2024.
