Analysis of Patient Preference for Cryotherapy Techniques

Dermatologic Surgery

TAKE-HOME MESSAGE

• The authors surveyed 58 patients over 1 year who had received cryotherapy through both a cryogen spray technique and cotton-tipped applicator technique during past clinic visits. Mean pain scores were lower with the cotton-tipped applicator method (2.48 vs 2.95; P=.0128). Patients also perceived the cotton-tipped applicator method as being more precise on a 5-point scale. Of the 42 patients who indicated a preference, 34 favored the cotton-tipped applicator over the spray technique.

• Although the study design is limited by recall bias, patients perceived cryotherapy with a cotton-tip applicator as being less painful and more precise than that with a spray technique. While prior studies have shown both methods to be equally effective, these results remind dermatologists to consider patient preference when choosing a technique.
