Silver Nitrate Cauterization

Chemical cauterization of GT can be painful.1 Silver nitrate is a known toxic substance, and many patients and caregivers aren’t comfortable self-treating at home.

“All topical steroids have been shown to cause skin atrophy.”

— Henge, 2006

Steroid Treatment

Topical steroids, such as Triamcinolone and Kenalog®, can have harsh side effects such as skin atrophy and decreased skin pigmentation (particularly noticeable in darker skin tones). Caution must be taken when applying on children, as they are more prone to side effects, including systemic reaction.2 Steroids also tend to lose their effectiveness over time due to tolerance buildup.
