Intralesional injection of triamcinolone acetonide (TA) which is widely used for the treatment of keloid, is painful and as a result many patients discontinue the treatment. We evaluated the effect of pretreatment with topical 60% lidocaine tape on pain and tolerability of intralesional TA treatment in keloid patients. We studied 20 patients with keloid who had previous experience with intralesional injection of TA and intolerable pain leading to discontinuation of treatment. All patients were pretreated with 60% lidocaine tape that was placed on the keloids for more than 120min before intralesional injection of TA. The patients’ assessment of pain was based on a 100-mm visual analog scale (VAS) anchored at 0 for ‘‘no pain’’ and 100 for ‘‘worst possible pain.” Pain assessment was performed immediately after the TA injection using VAS score. Finally, the patients’ tolerability towards this treatment was assessed. The Mean VAS score in the control patients who received intralesional injection of TA without lidocaine pretreatment was 82.6±14.4mm. On the other hand, the VAS score of the patients with lidocaine pretreatment was 18.9±11.3mm, which was significantly lower than that of the control group. Thus, the pain during intralesional injection of TA for treatment of keloids was relieved by pretreatment with lidocaine tape and patients could tolerate this therapy.
