Hyaluronidase Via LADD Scleroderma-induced Microstomia

Two treatment methods, ablative carbon dioxide (CO2) laser and intradermal hyaluronidase, will be combined to maximize the beneficial potential of each. Laser-assisted drug delivery (LADD) has been shown to be effective for the administration of medications in diverse skin diseases but not previously reported for the treatment of scleroderma-induced microstomia. By using this laser technique, the investigator can reduce the pain of typical hyaluronidase injections and reap the therapeutic benefit of the laser treatment itself. The investigator's goal is to create greater mouth mobility for chewing and speaking as well as improved oral hygiene, self-esteem, and overall quality of life. Each participant will undergo three separate laser sessions at 4 to 8-week intervals. Participants will also complete a follow-up visit three months after the last laser session to evaluate the response.

Efficacy of 3D-Printed Mouth Splints

The study will investigate the effectiveness of a 3D-printed mouth splint designed to increase dimensions of oral aperture and reduce disability associated with mouth contractures. The validated Mouth Impairment and Disability Assessment (MIDA) survey will be used to objectively measure patient progress in functionality and quality of life.

Clinical Effectiveness of a Patient-tailored Orthosis Based on 3-dimensional (3D) Scanner Modeling and 3D Printing Technology for Microstomia Caused by Burns : Pilot Study

Mircostomia is not clearly defined in terms of size, but is diagnosed when it causes difficulty in eating, pronounciation, or maintaining oral hygiene. Although various treatments have been applied to microstomia caused by mouth contracture after facial burns, there is no established protocol yet. This study aimed to confirm the clinical usefulness of patient-customized mouthpiece using 3D scanner modeling and printing technology.Each participant's mouths were scanned using a 3D scanner (Peel 3, Peel 3D, Canada). The scanned model was imported into the modeling software (Geomagic Design X, 3D Systems, USA). After modeling the mouthpiece to fit the maximum horizontal and vertical length of the mouth and the thickness of the lips, it was manufactured using a 3D printer (Form 4B Medical, Formlabs, USA). The participant was advised to wear the appliance throughout the day except during meals. As a primary outcome, the vertical and horizontal distances of the mouth were measured before and after wearing the patient-customized mouthpiece for 2 months. As secondary outcomes, the biological scar properties, the Vancouver Scar Scale (VSS), and the Patient and Observer Scar Assessment Scale (POSAS) scores were evaluated.
