The medial canthus is a frequent site for skin cancer and reconstruction after Mohs surgery can prove to be challenging. In the literature various reconstruction methods are recommended for these cases. Flap reconstructions are mostly transposition flaps from the glabella, skin with different properties from that in the canthal region, hence mostly requiring correction in a second stage.
To ascertain the utility of a different reconstruction method, applying island pedicle flaps for medial canthal lesions and obviating the necessity for second-stage corrections.
A review was undertaken of the medical records and photographs of patients who had a pedicle island flap reconstruction for medial canthal defects after Mohs surgery. There were four different possibilities: a pedicle island flap from the cheek, the back of the nose or the glabella or a combination of these flaps.
Sixteen patients were reconstructed by pedicle island flaps for defects of the medial canthal area. A follow-up for all patients after 1 year indicated that all patients showed good to excellent results. No cases of web deformation and ectropion were found.
This flap is not mentioned in textbooks in reference to the reconstruction of canthal lesions and its value for this particular location is probably underestimated.
内眦是皮肤癌的常见部位,Mohs 手术后的重建可能具有挑战性。在文献中,针对这些情况推荐了各种重建方法。皮瓣重建大多是从眉间转移的皮瓣,其皮肤特性与内眦区域不同,因此大多需要在第二阶段进行矫正。
确定一种不同的重建方法的实用性,即应用岛状蒂皮瓣重建内眦病变,避免第二阶段矫正的需要。
对接受 Mohs 手术后采用皮瓣岛状蒂皮瓣重建内眦缺损的患者的病历和照片进行了回顾。有四种不同的可能性:来自脸颊、鼻子背面或眉间的蒂岛皮瓣,或这些皮瓣的组合。
16 例患者采用蒂岛皮瓣重建内眦区缺损。对所有患者进行 1 年的随访后发现,所有患者均取得了良好至极好的结果。未发现任何眼变形和外翻的病例。
该皮瓣在涉及内眦病变重建的教科书中并未提及,其在特定位置的价值可能被低估。
