Liquid nitrogen cryosurgery is the most frequently used surgical treatment for verrucae. Its success rate is high and complications are rare. However, liquid nitrogen should be used with great care over bony prominences where skin and subcutaneous tissues are thin. We present 3 patients in whom the treatment of simple warts over bony prominences by liquid nitrogen resulted in full-thickness loss of skin. In 2 of them, extensor tendons of fingers were exposed and had to be covered with flaps. We conclude that expertise of the physician is of paramount importance in preventing similar complications in cryosurgery of verrucae.
液氮冷冻手术是治疗疣最常用的外科方法。其成功率高且并发症罕见。然而，在皮肤和皮下组织较薄的骨隆突部位使用液氮时应格外小心。我们报告3例因在骨隆突部位对寻常疣进行液氮治疗而导致皮肤全层缺失的患者。其中2例患者手指伸肌腱外露，不得不采用皮瓣覆盖。我们得出结论，在疣的冷冻手术中，医生的专业知识对于预防类似并发症至关重要。
