73岁男性患者,囚左耳后结节性基底细胞癌(basal cell cancer,BCC)溃疡形成而就诊,肿物大小为3.8cm×3.0 cm。采用Mohs显微外科手术切除肿瘤后,在耳后形成了5.3 cm×4.2 cm大小的组织缺损,深达骨质(图1)。耳后巨大皮肤软组织缺损修复非常困难,因为周围组织的伸展性差,且耳郭不能向后移位。该例患者颅骨的暴露更加剧了创面修复的困难。如果直接缝合很可能因张力过大而导致组织坏死和耳郭向后牵拉移位,而骨组织的暴露使修复进一步复杂化。如果用全 A 73-year-old male patient was diagnosed with ulceration of basal cell carcinoma (BCC) after his left ear. The size of the tumor was 3.8 cm × 3.0 cm. After removal of the tumor using Mohs microsurgery, a 5.3 cm × 4.2 cm tissue defect was formed behind the ear, reaching the bone mass (Figure 1). Rehabilitation of huge skin and soft tissue defects after ear is very difficult due to the poor extensibility of the surrounding tissue and the ear can not be displaced posteriorly. The patient’s skull exposure exacerbated the wound repair difficulties. If the direct suture is likely to be due to excessive tension caused by tissue necrosis and retraction ear traction, and bone tissue exposure to repair further complicated. If you use the whole
