Brief Summary:
Social interaction via facial mimic expression is crucial in human relationship and communication. Neural function disorder in this mechanism therefore affects human communication and social interaction. Facial nerve palsy is the paralysis of any structure innervated by the facial nerve, thus inibiting and severely compromising facial expression. In the last decade a new algorithm of treatment of facial paralysis has been raised. It connects the expertise of Aesthetic Medicine with the expertise of Plastic and Reconstructive Surgery. It is based on the use of Botulinum Toxin (BT) and Hyaluronic Acid (HA fillers). Botulinum toxin is a paralytic toxin that determine flaccid paralysis and is nowadays used in the static correction of facial paralysis with minimal invasiveness, optimal results and no time consumption. The HA fillers has the ability to restore facial volume loss and it is used in the treatment of facial palsy to harmonize symmetry. The aim is to study the effects of the BT and HA in facial paralysis patients in order to understand the efficacy of these products that have never been injected together in this type of patients. Primary objective. To evaluate the functional 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 (visit 0) and the end of the treatment period (visit 5, after 9 months). Improvement difference of at least 1 grade on the House-Brackmann scale, compared with the untreated group, will be considered clinically significant. Methods. The investigation is randomized open lab phase II single centre clinical trial. This experimental study proposes to evaluate a group of 70 patients affected by hemifacial paralysis of level 3 to 6 on the House-Brackmann scale. 35 patients will be treated (Group A) with both OnabotulinumtoxinA and hyaluronic acid fillers with a monitored follow up. A control group of 35 patients (Group B) who will not be treated, will be enrolled to compare the efficacy of the treatment. During the study all the AE/ADR will be recorded.
Detailed Description:
The patients will be evaluated with instrumental (3D pictures, neuro-physiological examination (EMG), radiological \[Magnetic Resonance Imaging (MRI)\], Cone Beam Computer Tomography (CBCT) and Ultrasound (US)) and non-instrumental analysis (clinical questionnaires and hystological analysis). The histology will be performed with both traditional and electronic approaches. The area of the biopsy will be the paralytic area in the two groups in order to study the soft tissue modulation of the injected molecules. Patient's qiality of life (QoL), through specifically test (FACE-Q), will be also evaluated.
