Here we describe the use of a novel lip-to-nose flap technique for nasal planum reconstruction after tumour removal in a dog. A mast cell tumour involving the nasal planum was first resected by removing the roof and the wing of the left nasal vestibule. An interpolation subdermal plexus flap was derived from the left caudal lip with vascular contribution from the lateral nasal artery. This lip-to-nose flap was rotated into the defect via a bridging incision. The mucocutaneous junction of the lip was used to emulate the keratinised nasal planum and the buccal mucosa was sutured to be congruent with the mucosa of the vestibule. This resulted in the lip-to-nose flap successfully closing the surgical defect and giving an aesthetic appearance similar to the original nasal planum.
在此，我们描述了一种新型唇至鼻皮瓣技术在犬肿瘤切除术后鼻平面重建中的应用。一只涉及鼻平面的肥大细胞瘤首先通过切除左鼻前庭顶部和翼部进行切除。一个皮下血管丛插入皮瓣取自左尾侧唇部，由鼻外侧动脉提供血供。该唇至鼻皮瓣通过一个桥接切口旋转至缺损处。唇部的黏膜皮肤交界处用于模拟角化的鼻平面，颊黏膜缝合后与前庭黏膜贴合。这使得唇至鼻皮瓣成功闭合手术缺损，并呈现出与原始鼻平面相似的美观外观。
