Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the functional (muscular enhancement) improvement of facial asymmetries due to facial nerve lesion after the treatment with OnabotulinumtoxinA and hyaluronic acid fillers compared with the untreated group. The evaluation will be performed analyzing the two groups at the baseline and at the end of the treatment period.;Secondary Objective: Group A -Evaluation of QoL, assessed through questionnaire before and after treatment (Visit 0 vs Visit 5) -Quantify and evaluate the improvement facial symmetry obtained by treatments (Visit 0, Visit 1, Visit 4 and Visit 5). -Aesthetic and Functionality, assessed through questionnaire, 3D photos, MRI, CBCT, US, Histological and EMG tests to underline treatment improvement on facial neuromuscular complex (Visit 0 vs Visit 5). -Evaluate adverse events and safety of the treatments Group A vs Group B -Evaluation of QoL, assessed through questionnaire (Visit 5) -Aesthetic and Functionality, assessed through questionnaire, 3D photos, MRI, CBCT, US, Histological and EMG tests on facial neuromuscular complex (Visit 5).;Primary end point(s): House-Brackmann scale score. La differenza di miglioramento di almeno 1 grado sulla scala House-Brackmann, rispetto al gruppo non trattato, sarà considerata clinicamente significativa;Timepoint(s) of evaluation of this end point: Visit 0 vs Visit 5

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Visit 0, Visit 1, Visit 2, Visit 3, Visit 4 and Visit 5; Visit 5; Visit 5; Visit 0 and Visit 5; Visit 0, Visit 1, Visit 4 and Visit 5; Visit 0, Visit 5;Secondary end point(s): Number and type of adverse events; Evaluation of QoL assessed through FACE-Q questionnaire in both groups; Facial aesthetic will be evaluated in both groups through: - the analysis of 3D-photography implemented with a face grid and the Arnett’s aesthetic analysis. Arnett’s aesthetic analysis evaluate the different areas of the face as “flat”, “soft”, “normal” and “protruded” -MRI provides quantitative data on the thickness of soft tissue (millimetric quantification of the thickness of the different areas) -CBCT provides quantitative data on the thickness of hard tissue (millimetric quantification of the thickness of the different areas) -US provides quantitative data on the thickness of soft tissue (millimetric quantification of the thickness of the different areas) and qualitative data on the tropism of muscules (Atrophy, hypotrophy, eutrophy, hypertrophy) -Histological analysis provides a qualitative analysis of patho-physiological condition of injected and not-injected tissue and specifically the effects on the fiber muscles. Histological and imaging (SEM and/or TEM) analysis should provide a through examination of tissue changes due to the physical introduction of the products, comparing different conditions in injected and not-injected tissue and eventually any effect on the fiber muscles. Possible physical and mechanical effect on treated tissues will be evaluated by histological evaluation to characterize tissue and cells involved in the modification, including the emergence and/or change of resident populations via the application of straightforward approaches. Histological evidence is then supported and completed with TEM and /or SEM. -EMG provides electric potentials of the facial neuromuscular complex in order to evaluate the activity an
