A Pilot Study of the Analysis of Facial Motion using Digital Image Speckle
Correlation (DISC) in Patients Diagnosed with an Acoustic Neuroma.

What is the purpose of this study? To determine if acoustic neuromas influence facial nerve motor function on a level undetectable by the human eye. The technique called Digital Image Speckle Correlation (DISC) will be used to detect facial motion. DISC calculates facial motion from two pictures taken in quick succession. By comparing the normal side of the face (e.g. the side without tumor involvement) with the affected side of the face (e.g. the side with tumor involvement), we hope to determine whether digital imaging and analysis can be used to predict patient outcome following acoustic neuroma surgery.

Who qualifies to participate in this study?

  • Age > 18 years
  • Patients diagnosed with Acoustic Neuroma
    • Observation only, pre or post-surgery, pre or post radiotherapy or treated with multiple modalities.

Who does not qualify for this study?

  • Patients with a history of a stroke affecting the face
  • Patients with a history of Bell’s Palsy
  • Patients with a history of significant facial surgery or trauma

What are the procedures if I decide to participate in this study?

The study is being completed at Stony Brook Medicine Department of Neurosurgery outpatient clinics; but we will be traveling to sites to be determined.

If you decide to participate, your total involvement will be 20-30 min and your part will involve:

  • You will be asked to review, discuss and sign a research consent form.
  • Your medical history will be obtained in a coded manner.
  • A review of the nerves in your head will also be performed. This is a non-invasive test of the major nerves in your head to see if you have any deficits.
  • You will be asked to smile and rest (or make a facial expression such as anger, happiness, or surprise) in front of the digital camera and pictures will be taken. You will be asked to smile then rest approximately three-four times.

What are my risks in participating?

There are no physical risks to you by having your information obtained and photograph taken. The only risk involved is the possibility that you may be identified from your photograph if it is published in a scientific journal or presented at a scientific meeting. We will take steps to make sure that all of the information, both physical and electronic will be kept private and confidential.

What are my obligations if I agree to participate? There is no cost to you, and you can withdraw or decline to participate at any time. Your decision to participate does not in any way affect your relationship with the Acoustic Neuroma Association (ANA), and no funding from the ANA is being used to complete this study. Your personal information is never shared.
