Surgical treatment of ear carcinomas needs the selection of the appropriate reconstructive techniques, which depends on the location and the dimensions of the defect after excision of the cancer and the quality of blood supply to the peri-lesional skin. The aim of this study was to evaluate the efficacy and reliability of a new axial island retroauricular flap (middle-retroauricular island flap M-RIF) for coverage of non-helical ear defects with direct donor site closure.
All patients, from January 2013 to January 2020, with skin tumors of the non-helix region and undergoing a combined skin-cartilage excision with M-RIF local flap reconstruction under local anesthesia, were enrolled in the study.
18 patients (14 men and 4 women) underwent auricle skin-cartilage excision and M-RIF flap reconstruction. The mean age was 65 years (range, 60-85); the type of primary lesions were 12 BCC and 6 SCC. One flap wound dehiscence and one donor site infection and partial necrosis of the posterior auricular skin occurred; no other complications were recorded.
The M-RIF flap is a valid surgical option when dealing with non-helical defects of the anterior pinna. It allows the reconstruction of the defect of the entire anterior surface of the auricle apart from the helix and the lobe and primary donor site closure.
耳部恶性肿瘤的手术治疗需要选择合适的重建技术，这取决于癌症切除后缺损的位置和大小以及病变周围皮肤的血供质量。本研究的目的是评估一种新的轴型岛状耳后皮瓣（耳后中间岛状皮瓣M-RIF）用于覆盖非耳轮部耳部缺损并直接关闭供区的有效性和可靠性。
纳入2013年1月至2020年1月期间所有患有非耳轮区皮肤肿瘤且在局部麻醉下接受联合皮肤软骨切除及M-RIF局部皮瓣重建的患者。
18例患者（14例男性和4例女性）接受了耳廓皮肤软骨切除及M-RIF皮瓣重建。平均年龄为65岁（范围60 - 85岁）；原发病变类型为12例基底细胞癌和6例鳞状细胞癌。发生1例皮瓣伤口裂开、1例供区感染及耳后皮肤部分坏死；未记录其他并发症。
M-RIF皮瓣是处理耳廓前部非耳轮部缺损时一种有效的手术选择。它能够重建除耳轮和耳垂外耳廓整个前表面的缺损并直接关闭供区。
