Comparing the Impact of AMNIOEFFECT Application vs Standard of Care on Post-Operative Healing in Patients Who Have Undergone Thyroid and Parathyroid Surgery Via the Transcutaneous Approach

The purpose of this study is to understand how placing Amnioeffect on patients having transcutaneous thyroid or parathyroid surgery affects surgery scar appearance, pain, and the ability to swallow and compare it to patients who do not have anything placed during surgery. The Food and Drug Administration regulates the use of Amnioeffect for homologous use. Both Amnioeffect application and no Amnioeffect application are considered standard of care; however, for the purpose of this study, the use of Amnioeffect during surgery will be considered the intervention, and no Amnioeffect application will be the standard of care.

About this study

A product called AMNIOEFFECT has been developed as a barrier intended for use in the treatment of acute and chronic wounds, providing a protective environment to support the healing process. Manufactured by the company MIMEDX, it is a placental-based allograft made of lyophilized human amnion/intermediate/chorion membrane (LHACM). During the study, 334 patients who are to undergo transcutaneous thyroid or parathyroid surgery will be recruited to participate over a one-year period. Using a randomized control approach, the study would be conducted to evaluate the impact of AMNIOEFFECT placed over the strap muscle closure before the subcutaneous tissues and skin are reapproximated, compared to standard of care on post-operative pain, swallowing ability, and cosmesis (conferring of beauty) as indicated by scar appearance.

Treatment and study plan

Amnioeffect is a placental-based allograft made of lyophilized human amnion/intermediate/chorion membrane (LHACM)

Primary outcomes

  1. Improvement of scar appearance

    Time frame: Pre-procedure, 1 month post procedure, 3 months post procedure

    Measured by use of the Vancouver Scar Scale; scores rating on vascularity, pigmentation, pliability, and height. Total score ranges from 0-13, with 0 being "normal" appearance.

  2. Determine swallowing effectiveness

    Time frame: Pre-procedure, 1 month post procedure, 3 months post procedure

    Measured by use of the SWAL-QOL score; this survey uses a Likert scale rating to ask questions regarding swallowing difficulties and associated quality of life impacts. Higher scores reflect lower impact on quality of life; lower scores would indicate higher impact.

  3. Improvement in Pain Score

    Time frame: Pre-procedure, 1 month post procedure, 3 months post procedure

    Measured by use of the Visual Analog Scale; scoring 0 for no pain-10 for unbearable pain.
