Summary

Researchers are testing custom silicone splints that fit inside the mouth to gently stretch facial tissue that has tightened or scarred after burns, trauma, or gunshot wounds. The study includes people aged 7 and older whose scars limit mouth opening, chewing, speaking, or facial expression. A speech-language pathologist fits each participant with one or more splints chosen for their specific areas of tightness. The team measures changes in mouth opening, facial symmetry, and facial movement to see whether the splints help and to work out the best way to use them.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
custom silicone intraoral stretching splints
What this could lead to
If the splints help, they could offer a non-surgical way to loosen tight facial scars and improve mouth opening and facial expression for people recovering from burns or facial trauma.
What could go wrong
This is a small study of 50 people, and stretching scar tissue takes time and daily commitment. Results may not apply to everyone, and some scars may still need surgery.
