Study Compares Methods for Treating Recalcitrant Keloids

Punch excision (PE) followed by immediate cryotherapy could be a viable and simpler alternative to core excision (CE) for the treatment of recalcitrant keloids, according to the results of a small retrospective study.

The method “offers similar efficacy, faster healing, and fewer complications,” one of the study authors, Jinwoong Jung, MD, said in an interview following the annual meeting of the American Society for Dermatologic Surgery, where he presented the study results during an oral abstract session.

For the study, Jung, a dermatologist at Yonsei University College of Medicine, Seoul, South Korea, and colleagues retrospectively analyzed 22 patients with recalcitrant keloids treated with cryotherapy immediately following either PE or CE between May 2019 and March 2024. They used the Vancouver Scar Scale (VSS) to assess treatment efficacy.

Of the 22 patients, 16 underwent treatment with CE and six underwent treatment with PE. Pretreatment VSS scores showed no significant differences between the groups (P = .535). The CE group had a reduction in the VSS score from 8.13 to 4.00, while the PE group had a reduction from 7.83 to 3.67, but these declines did not differ significantly (P = .737). The PE group exhibited a shorter healing time than the CE group (a mean of 43.5 vs 63.87 days, respectively), though this difference was not statistically significant (P = .129).

“The uniqueness of this work lies in its simplified use of PE for recalcitrant keloids, which demonstrated efficacy comparable to CE, with the potential advantage of faster healing times,” Jung said. “Future studies with larger sample sizes and extended follow-up periods could help establish this approach as a standard treatment method.”

He acknowledged certain limitations of the study, including its small sample size and the lack of long-term follow-up data. The researchers reported having no relevant disclosures.
