To describe the use of the upper lip for reconstruction of the external nose and closure of large facial defects in dogs.
Four dogs with facial defects with exposure of the underlying nasal cavity.
Short case series.
A variation of the lip-to-lid technique was used to reconstruct one-half of the external nose after resection of a mast cell tumor in one dog. A full-thickness labial transposition flap (upper lip) was used to reconstruct facial and nasal defects exposing the nasal cavity. A cylindrical mucosal graft was employed in the restoration of nostril patency in one dog.
The lip-to-lid variation (also known as lip-to-nose) restored the right nostril and nasal planum after mast cell tumor resection in one dog. In three dogs, the nasal defects were reconstructed with full-thickness upper labial transposition flaps. Restoration of nostril patency in one dog was also aided by the cylindrical mucosal graft.
The full-thickness labial transposition flap and the lip-to-lid flap variation were successfully used to reconstruct major defects of the external nose and facial defects involving the nasal cavity.
Composite flaps of the upper lip should be considered to close problematic nasocutaneous fistulas and restore function to the external nose. The upper lip provides a source of mucosa to restore patency of stenotic nares or obstructed nostrils.
描述在犬中使用上唇重建外部鼻子和封闭大的面部缺损。
4 只面部有缺损且鼻腔外露的狗。
短病例系列。
在一只狗的肥大细胞瘤切除后，采用唇至睑技术的一种变体来重建外部鼻子的一半。全厚唇瓣（上唇）用于重建面部和鼻缺损以暴露鼻腔。在一只狗中，使用圆柱形粘膜移植物恢复鼻孔通畅。
唇至睑的变体（也称为唇至鼻）在一只狗的肥大细胞瘤切除后恢复了右侧鼻孔和鼻平面。在 3 只狗中，全厚上唇瓣用于重建鼻缺损。圆柱形粘膜移植物也有助于一只狗的鼻孔通畅恢复。
全厚唇瓣和唇至睑瓣的变体成功地用于重建外部鼻子的主要缺陷和涉及鼻腔的面部缺损。
应考虑使用上唇复合瓣来封闭有问题的鼻皮瘘并恢复外部鼻子的功能。上唇提供粘膜来源，以恢复狭窄的鼻孔或阻塞的鼻孔的通畅。
