Summary

This trial explores combining two treatments to improve mouth mobility, hygiene, self-esteem, and quality of life for people with scleroderma-induced microstomia. Laser-assisted drug delivery used to reduce pain of injections. 3 laser sessions at 4-8 week intervals, followed by 3mo follow-up.

Who is the study for?
This trial is for adults over 19 with scleroderma-induced microstomia, who are patients at specified clinics. They must be able to participate and have no severe dementia or seizure disorders. It excludes pregnant or breastfeeding women, those under 18, anyone cautious of hyaluronidase due to bee stings/bites, with infections near the treatment area, prior treatments like LADD or adverse reactions.
What is being tested?
The study tests a combination of CO2 laser therapy and intradermal hyaluronidase injections using Laser-assisted drug delivery (LADD) on people with small mouths from scleroderma. The goal is to improve mouth mobility and quality of life through three laser sessions followed by an evaluation after three months.
What are the potential side effects?
Potential side effects may include pain from injections reduced by the laser technique, skin irritation or inflammation at the treatment site, allergic reactions especially in those sensitive to bee products due to hyaluronidase content.
