Tangential excision (shaving) is an effective surgical technique for the excision of nevocellular nevi on the trunk, limbs, and scalp. There are few studies on the application of this technique to lesions on the face.
To demonstrate the technique of tangential excision for the removal of nevocellular nevi on the face and to evaluate the cosmetic results, recurrence index, and possible complications.
Two hundred and fifteen patients with multiple nevocellular nevi on different aesthetic units of the face (total of 225 lesions) were selected. All the lesions were removed by tangential excision. The patients returned for postsurgical evaluation at 30, 60, and 90 days.
The results were evaluated in relation to the skin type, sex, age, and histologic type of the lesions. An excellent result was achieved in 90.7%, good in 8.4% and poor in 0.9%, with a low index of complications. For comparison, the face was divided into seven aesthetic units.
Tangential excision is an alternative surgical technique for the treatment of nevi. It is simple, fast, and efficient, has low risks and low cost for the patient, and yields excellent results when used for cosmetic purposes.

展示用于切除面部痣细胞痣的切线切除技术，并评估美容效果、复发率及可能的并发症。
选取215例面部不同美学单元有多发性痣细胞痣的患者（共225处病变）。所有病变均通过切线切除去除。患者在术后30天、60天和90天复诊进行术后评估。
根据病变的皮肤类型、性别、年龄和组织学类型对结果进行评估。90.7%的患者效果极佳，8.4%的患者效果良好，0.9%的患者效果较差，并发症发生率较低。为作比较，将面部分为七个美学单元。
切线切除是治疗痣的一种替代手术技术。它简单、快速且有效，对患者风险低、成本低，用于美容目的时效果极佳。
