Treatment of Hypertrophic Granulation Tissue: A Literature Review.

Abstract

Hypertrophic granulation tissue (HGT) is an uncommon but a frustrating complication of wound healing. Given its low prevalence and often refractory nature, many treatment options have been explored. No comprehensive review exists on HGT management in dermatology literature; thus, the authors hope to compile a review of available treatments. An exhaustive key word search of 3 databases was performed for treatment of HGT. Results from these reports were summarized in this review. Methods of treatment included silver nitrate, topical steroids (n = 11), intralesional steroids (n = 55), steroid tape (n = 25), surgical removal, polyurethane foam dressing (n = 32), and pulsed-dye laser (n = 13). With all treatment methods, the cases and studies reported varying degrees of successful treatment with HGT reduction. Given the lack of published literature, it remains unknown whether the initial injury preceding HGT formation determines treatment modality success. For HGT refractory to silver nitrate, choice of treatment depends on accessibility, ease of use, cost, and location of the wound. Intralesional and topical steroids should both be considered. Polyurethane foam can be considered an adjunct treatment. If resources allow, laser treatment should also be considered.
