Summary Background Photodynamic therapy (PDT) is an effective treatment for actinic keratoses, Bowen’s disease and basal cell carcinoma. The main drawback of PDT is pain during application. Objectives To compare the efficacy of supratrochlear and supraorbital nerve block with cold air analgesia to control the pain experienced during PDT. Methods A controlled open clinical trial was conducted in 34 patients having multiple actinic keratoses in the frontal region treated with PDT. On one side of the frontal region the supratrochlear and supraorbital nerves were blocked, while on the other side cold air was used as the method of analgesia. Pain was recorded on a visual analogue scale after treatment. Results Thirty‐one of 34 patients reported less pain in the zone treated with nerve block. This difference was statistically significant. Conclusions Nerve block is superior to cold air and is an easy, safe, effective means of controlling the pain associated with PDT.
