NCT03974763

Brief Summary

This study will be unique for the rehabilitation of patients with facial paralysis in that the focus is to generate novel 3D facial soft tissue measures to characterize the condition and temporal changes, and on the generation of future testable hypotheses to optimize surgical interventions and outcomes. In addition, the investigators will extend our previous work, beyond the facial circumoral and lip areas/zones, to characterize additional facial zones specific for facial paralysis. The approach for facial mapping of soft tissue movement, when validated through this proposed study, can be used for both surgical planning and to support the development and training of implantable facial pacing devices. Mapping both normal facial movements and movements of patients with unilateral facial paralysis are vital to describe the temporal and spatial course of the recovery process. Ultimately, this information can be used to inform clinicians on the precise placement of these devices and the signal strength needed to facilitate movements in the required 'paralyzed' facial zones until the recovery process has been completed.

Outcome Measures

Primary Outcomes (15)

  • To quantitatively evaluate the range of facial soft tissue disability in patients with acute, unilateral, flaccid facial paralysis and track the changes over time (3-month recovery period).

    First outcome measure for facial soft tissue disability = Maximum displacement (mm)

    December 2019

  • To quantitatively evaluate the range of facial soft tissue disability in patients with acute, unilateral, flaccid facial paralysis and track the changes over time (3-month recovery period).

    Second outcome measure for facial soft tissue disability = velocity (mm/s)

    December 2019

  • To quantitatively evaluate the range of facial soft tissue disability in patients with acute, unilateral, flaccid facial paralysis and track the changes over time (3-month recovery period).

    December 2019

  • To compare the facial disability in the patients with a group of age- and sex-frequency matched normal subjects.

    First outcome measure for group comparison = difference in maximum displacement (mm) between patients with facial disability and control group subjects

    December 2019

    December 2019

  • In patients with acute, unilateral, flaccid facial paralysis, to compare the current, qualitative, clinical assessment methods for facial disability.

    First outcome measure = average correlation across surgeons for their ratings on the House-Brackman scale and the patients' mean measures of maximum displacement

    December 2019

  • In patients with acute, unilateral, flaccid facial paralysis, to compare the current, qualitative, clinical assessment methods for facial disability.

Study Arms (2)

Test Group

Patients with acute, unilateral, facial paralysis (Bell's Palsy)

Control Group

A group of age- and sex-frequency matched 'normal' controls. Based on past research, gender and age are possible confounders of facial movement/function. Thus, the control group will be frequency-matched to the patient group on gender and age.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The subjects for this study will be adults 18 to 75 years. The subjects who are potentially eligible for participation will be identified through the participating Centers: For the patients with facial paralysis through the Facial Nerve Center (FNC) at Massachusetts Eye and Ear Infirmary (MEEI); and for the control subjects through Tufts University School of Dental Medicine (TUSDM). Subjects recruited from MEEI will attend TUSDM for testing where Dr. Trotman maintains her Facial Animation laboratory. The participating surgeon is Dr. Tessa Hadlock and she will be responsible for the clinical care of all patients.

  • Able to attend baseline visit at Tufts within 6 weeks of onset of the condition and with an estimated potential for recovery between 6-12 weeks
  • Patient interest/willingness to participate in the study
  • An ability to comprehend verbal instructions; and an age range of 18 to 75 years

You may not qualify if:

  • Facial movement disorders due to primary muscular dysfunction or hemifacial spasm in the absence of synkinesis
  • Complaints of facial paralysis but no evidence of weakness on physical examination
  • Previous facial soft tissue surgery and/or Orthognathic surgery
  • Mental or hearing impairment to the extent that comprehension or ability to perform the tests is hampered
  • Subject interest/willingness to participate in the study
  • An ability to comprehend verbal instructions
  • An age range of 18 to 75 years
