More recently, in study by Chuangsuwanich et al, 45 patients with excised keloids were treated with imiquimod 5% cream 2 weeks after the operation, on alternate nights, for 8 weeks. [51] After a follow-up period of 6-9 months, 10 of the keloids recurred (28.6% overall recurrence rate), with adverse effects found in 13 patients (37.1%). Interestingly, the keloids localized on the pinna had the lowest recurrence rate (2.9%) compared with those at the chest wall or neck (83.3% and 14.3%, respectively).
