A keloid represents an excessive overgrowth of skin beyond the boundaries of an injury. Earlobe keloids usually follow ear piercing and can become large, sometimes producing remarkable disfigurement. Surgical excision, pressure dressing, intralesional corticosteroid injection, cryosurgery, radiation, and lasers have all been used to treat earlobe keloids. However, none has produced uniformly satisfactory results. Combinations of more than one modality have also been employed to yield successful outcomes. We describe cryotherapy as a single modality to treat seven-year-old, multiple earlobe keloids. Three cryotherapy sessions with two freezing-thawing cycles of 30-40 seconds' freezing time and two minutes' thawing time, undertaken one month apart, resulted in complete flatness of the keloids and no recurrence after 5 years. We also evaluate keloid-related and operational factors that determine the success of cryotherapy as a monotherapy for earlobe keloids.
瘢痕疙瘩是指皮肤在损伤边界之外过度增生。耳垂瘢痕疙瘩通常继发于耳部穿刺，且可能长得很大，有时会造成明显的毁容。手术切除、压力敷料、病灶内注射皮质类固醇、冷冻手术、放射治疗和激光治疗均已用于治疗耳垂瘢痕疙瘩。然而，这些方法均未取得一致的满意效果。也有采用多种方式联合治疗以取得成功的案例。我们描述了采用冷冻疗法这一单一方式治疗一名7岁患儿的多处耳垂瘢痕疙瘩的情况。每隔一个月进行三次冷冻治疗，每次有两个冻融循环，冷冻时间为30 - 40秒，解冻时间为两分钟，结果瘢痕疙瘩完全变平，5年后未复发。我们还评估了决定冷冻疗法作为耳垂瘢痕疙瘩单一疗法成功与否的瘢痕疙瘩相关因素和手术因素。
