What this trial studies

This observational study aims to assess the outcomes of facial reanimation surgeries in patients with unilateral facial paralysis. Participants will undergo a free gracilis muscle transfer and will be evaluated using 3D analysis to measure facial disability and self-perception of facial appearance and well-being. The study will track patients at three time points: before surgery, and at five and eighteen months post-surgery, to capture the regenerative process and overall satisfaction. The research will focus on various surgical techniques and their impact on patients' quality of life.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with unilateral facial paralysis scheduled for smile reconstruction surgery.

Not a fit: Patients with major facial deformities or conditions affecting facial movement due to primary muscular dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of surgical outcomes and improve patient satisfaction and quality of life for those with facial paralysis.

How similar studies have performed: While there have been studies on facial reanimation, this specific approach focusing on 3D analysis and patient-centered outcomes is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patients with unilateral facial paralysis scheduled for smile reconstruction using free gracilis muscle transfer driven by one of four neuronal inputs, specifically, the trigeminal nerve (nV), a cross-face nerve graft (nVII), dual innervation combining the trigeminal nerve, a cross face nerve graft, and patients who have midfacial modifications that involve performing direct coaptation between the trigeminal nerve and a branch to the native zygomaticus major muscle (5-7 transfer) and selective neurolysis in which several facial nerve branches that innervate muscles antagonistic to the smile animation are transected.
* Patient/parent interest/willingness to participate in the study
* An ability to comprehend verbal instructions
* An age range of 18 to 75 years

Exclusion Criteria:

* Presence of a major facial deformity/condition either congenital or acquired e.g. hemifacial microsomia, cancer
* Facial movement disorders due to primary muscular dysfunction or hemifacial spasm in the absence of synkinesis
* Mental or hearing impairment to the extent that comprehension or ability to perform the tests is hampered
