Abstract：
Nasal planum reconstruction is a surgical challenge, and several surgical techniques have been described. The objective of this study was to describe the rotation alar fold flap technique and to report clinical outcomes in a short case series. The feasibility of the technique was first assessed in a canine cadaveric model. The rotation alar fold flap was obtained by a single sharp horizontal incision of the dorsolateral nasal cartilage, preserving the caudal mucosal attachment to the ventral nasal concha. The flap was then rotated ventro-medially for the reconstruction of the ventral aspect of the nasal planum unilaterally or bilaterally. The rotation alar fold flap technique was used following a subtotal or partial planectomy for excision of a squamous cell carcinoma or mast cell tumors in three dogs. No intraoperative complications were recorded. Superficial surgical site infection was reported in two cases and minor dehiscence was reported in one case. However, survival of the flap was not affected. The cosmetic and functional outcomes were considered very satisfactory in all cases. The rotation alar fold flap technique offers a safe, valuable, feasible, functional and aesthetically satisfactory alternative surgical option for selected cases of localized tumor involving the central and ventral planum.
摘要：
鼻平面重建是一项手术挑战，已经描述了几种手术技术。这项研究的目的是描述旋转翼瓣技术，并在简短的病例系列中报告临床结果。首先在犬尸体模型中评估了该技术的可行性。通过鼻背外侧软骨的单个尖锐水平切口获得旋转翼状褶皱皮瓣，保留尾粘膜附着在腹侧鼻甲上。然后将皮瓣向腹中旋转，以单侧或双侧重建鼻平面的腹侧。在三只狗的鳞状细胞癌或肥大细胞肿瘤切除术后，使用旋转翼状折叠皮瓣技术。术中无并发症记录。2例报告了表面手术部位感染，1例报告了轻微的裂开。然而,皮瓣的存活没有受到影响。在所有情况下，美容和功能结果都被认为非常令人满意。旋转翼瓣折叠技术提供了一个安全的，有价值,可行,对于某些涉及中央和腹侧平面的局部肿瘤病例，功能和美学上令人满意的替代手术选择。
