Actinic keratoses
Actinic keratoses
Actinic keratoses are a well-described and widely practiced indication for cryotherapy. Lesions may be treated with a cryospray or by using a cotton-tipped applicator, though the latter is now used infrequently. One study from 1982 reported a 98.8% cure rate in the treatment of 1018 actinic keratoses in 70 patients. At follow-up ranging from 1 to 8.5 years after the treatment, 12 recurrences were noted.21 Cryosurgery is often the treatment of choice for discrete lesions given its quick treatment time, wide availability, and minimal expense. A more recent Cochrane Database review from 2012 evaluated various available fields and individual lesion therapies for actinic keratoses. Photodynamic therapy, compared to cryotherapy, was more effective and yielded an improved cosmetic outcome for treating individual actinic keratoses.22 This finding should, however, be weighed against the convenience and cost-effectiveness of cryotherapy.
