自1993年以来,我们采用耳后皮下蒂皮瓣修复耳甲腔缺损11例,效果满意。临床资料本组男9例,女2例。年龄17～62岁。病因:良性肿瘤4例(其中基底细胞乳头状瘤3例、日光性角化病1例)、恶性肿瘤2例(其中鳞状基底细胞癌1例、恶性黑色素瘤1例)、色素痣3例、毛细血管瘤1例、化脓性肉芽肿1例。面积:最小0.6cm×0.8cm,最大1.5cm×2.4cm(包括部分耳甲艇缺损)。深度:侵及软骨者6例、软骨膜者2例、软骨膜表层者3例。皮瓣全部成活。随访6个月～3年,肤色质地正常,瘢痕不明显,效果满意(图1～3)。手术方法局麻下,根据病因切除病损达软骨膜(或切除软骨),根据耳甲腔缺损创面的大小、形状,在耳后乳突部设计并切取一与耳廓根部平行的舌形皮瓣,深达骨膜表层,皮瓣根部横行切除一小条浅层皮肤,宽度与耳甲组织全层的厚度相当,形成皮下蒂皮瓣。在耳后耳廓根部相应部位横行切穿耳甲组织形成隧道,隧道宽度略大于舌形皮瓣的宽度。将耳后皮瓣通过耳甲隧道,移转到耳前,修复耳甲腔缺损创面。皮瓣的无皮肤区边缘与两侧耳甲组织创缘缝合,供区直接拉拢缝合。讨论耳甲腔的皮肤菲薄,皮下组织极为薄弱,皮肤与软骨膜紧密粘连,因此,在病损切除后,难以直接缝合或应 Since 1993, we have used the posterior subcutaneous pedicle flap to repair 11 cases of conchae of cavum, with satisfactory results. Clinical data The group of 9 males and 2 females. Age 17 ~ 62 years old. Etiology: benign tumors in 4 cases (including basal papilloma in 3 cases, 1 case of solar keratosis), 2 cases of malignant tumors (including squamous basal cell carcinoma in 1 case, 1 case of malignant melanoma), nevus in 3 cases , 1 case of capillary hemangioma and 1 case of pyogenic granuloma. Area: the smallest 0.6cm × 0.8cm, the largest 1.5cm × 2.4cm (including part of the condyloma airship defect). Depth: invasion of cartilage in 6 cases, 2 cases of cartilage, perichondrial surface in 3 cases. Flap all survived. Follow-up 6 months to 3 years, the skin texture is normal, the scar is not obvious, the effect is satisfactory (Figure 1 ~ 3). Surgical methods under local anesthesia, according to the etiology resection of the lesions up to the perichondrium (or cartilage removal), according to the size and shape of the wound surface of the conchae of cavum cavum, in the posterior mastoid design and cut a tongue parallel to the auricle Flap, deep as far as the periosteum surface, the flap root transverse resection of a small shallow skin, the width and thickness of the full thickness of the condylar tissue to form a subcutaneous pedicle flap. In the corresponding part of the auricle root ear transverse cut through the formations of tunicate tunnel, the tunnel width slightly larger than the width of the tongue flap. After the ear flap through the tunnel of the concha, transferred to the ear, repair the ear cavity defect. Skins without skin area edge and bilateral ear ear tissue wound edge, for the area directly draw suture. Discuss the meager skin of the cavum concha, the subcutaneous tissue is extremely weak, the skin and the perichondrium close adhesion, therefore, after lesion removal, it is difficult to direct suture or should
