3D Dynamic and Patient-Centered Outcomes of Facial Reanimation Surgery in Patients With Facial Paralysis

Summary

In this study, patients who have undergone facial paralysis surgery will be asked to participate. The goal of this study is to compare the facial disability and perception outcomes of facial reanimation surgeries in patients with extensive and permanent, unilateral paralysis using 3D analysis, and compare patient-centered outcomes of facial appearance, well-being, and satisfaction using validated questionnaires. The focus point of this study will be on outcomes of mid-facial reanimation surgeries in patients with more extensive and permanent, unilateral, paralysis of varied etiology and presentation.

The specific aims of the study are as follows. Specific Aim 1. To quantitatively determine the surgical effects/impact on facial disability (facial impairment and disfigurement) among four surgically treated groups of patients with unilateral facial paralysis who undergo free gracilis muscle transfer driven by (1) a trigeminal nerve (nV) graft, (2) a crossface nerve graft (nVII), (3) dual innervation comprising both nerves, and (4) midfacial modification.

1. We will compare the changes in facial disability among the groups before and after surgery, and the differences in facial disability between each surgery group and the controls before and after surgery.
2. Specific Aim 2. To compare among the surgery groups the changes in self-perceptions of facial appearance and well-being that occur due to facial reanimation surgery, and to compare the surgery groups before and at 18 months to historical controls recruited during the tenure of the R21 grant.
3. Specific Aim 3. In patients with facial paralysis, to compare surgeons' current qualitative assessment and 2D, quantitative assessment of facial impairment and disfigurement with the objective, 3D, quantitative assessments in order to determine the clinical utility of the 3D assessment approach as an outcome measure and relevance for dissemination to the surgical community.

Conditions

• Facial Paralysis

Interventions

OTHER

Psychosocial scales/questionnaires

We will use three psychosocial scales/questionnaires for this patient population to gauge patients' perceptions of the impact of their paralysis and their recovery. The questionnaires will be completed by the patients at baseline, and 18 months after surgery. Moreover, we also will compare patient perceptions to the patient-related responses with clinical scoring made by the surgeons using the eFACE,6 Face-Gram/Emotrics12 software, and the 3D dynamic measures.

OTHER

3D Facial Measurements

3D dynamic (objective) facial movement data will be collected first (estimated time 1 hour), followed by static 3D photographic data (estimated time 15 minutes), and then video data of the different facial animations (estimated time 15 minutes).
