Study Arms (1)
keloid or hypertrophic scars
All patient including all skin types with keloid or hypertrophic disease receiving Intralesional Cryotherapy
Interventions
Intralesional (IL) cryotherapy is a treatment for keloids and hypertrophic scars, in which the scar is frozen from inside with the use of a cryoneedle
Eligibility Criteria
A mixed patient population with all Fitzpatrick skin types
You may qualify if:
- Keloids, defined as excessive scar tissue raised above skin level and proliferating beyond the confines of the original lesion
- Hypertrophic scars1 older than 12 months and insensitive to other treatments. Keloids were distinguished from hypertrophic scars based on the clinical judgment of experienced plastic surgeons and on the age of the scar (\>1yr)
- A period between previous treatment and IL cryotherapy covered a minimum of 12 weeks
- Patients with all Fitzpatrick17 skin types
- Patients older than 10 years of age
You may not qualify if:
- pregnancy
- diabetes mellitus
