Abstract

Background
Keloid treatment is challenging because of the high likelihood of recurrence and a lack of definitive treatment combinations. The treatment of bulky and recurrent keloids is particularly difficult. We investigated the administration of extralesional cryotherapy (EL) in conjunction with intralesional (IL) triamcinolone (TA) injections as adjuvant therapy after surgical excision for the management of keloids.
Methods
Among all patients who visited our scar laser center between January 2016 and August 2017, 54 patients who underwent IL keloid excision with EL cryotherapy and IL TA injection as adjuvant therapy were included in this retrospective study. We examined sex, site, the number of cryotherapy sessions and TA injections, symptoms after surgery, and recurrence. The Vancouver Scar Scale (VSS) was used as to quantify treatment outcomes.
Results
Among 54 cases of IL keloid excision, after an average of 6.26 cryotherapy sessions and IL TA injections as combined adjuvant treatment, the lesion was controlled without recurrence in 49 cases. Relapse occurred in five patients, requiring additional treatment and reoperation. For 49 patients with photographic data, the average VSS score before and after treatment improved from 10.1 to 5.0. In 17 patients in whom symptoms recurred after surgery, all symptoms were controlled and maintained with adjuvant therapy.
Conclusions
Initial direct surgical excision, followed by a combination of EL cryotherapy and IL TA injections, was shown to be effective in challenging cases of large and recurring keloids.
