The aim of this study was to evaluate the angiosome of the superior and inferior labial arteries within the superior and inferior labia and to describe superior and inferior labial musculomucosal axial pattern flaps that can be used for intra-oral wound reconstruction. This study also presents the clinical use of a superior labial musculomucosal flap in a dog.
The common carotid arteries of six canine cadavers were injected with barium sulphate. The skin of the face and labial mucosa was removed and radiographed to study the vascular supply of the superior and inferior labia.
The angiograms in all dogs demonstrated that the superior and inferior labial arteries were located within the musculomucosal layer of the labia. At the junction of the rostral and caudal half of the upper lip, extensive choke anastomoses joined the angiosome of the infra-orbital artery. The inferior labial artery perfused the caudal half of the lower labium and had extensive choke anastomoses with the middle and rostral mental arteries.
The musculomucosal flaps of the superior and inferior labia contain a rich arterial blood supply, which suggests that these flaps may survive in live dogs. The superior labial musculomucosal flap was successfully used to reconstruct a large cleft palate in a single clinical case.
本研究旨在评估上、下唇内上、下唇动脉的血管体，并描述可用于口腔内伤口重建的上、下唇肌黏膜轴型皮瓣。本研究还介绍了上唇肌黏膜瓣在犬类中的临床应用。
对六只犬类尸体的颈总动脉注射硫酸钡。去除面部皮肤和唇黏膜并进行放射摄影，以研究上、下唇的血供。
所有犬类的血管造影显示，上、下唇动脉位于唇的肌黏膜层内。在上唇的前半段和后半段交界处，广泛的吻合支连接眶下动脉的血管体。下唇动脉灌注下唇后半段，并与颏中动脉和颏前动脉有广泛的吻合支。
上、下唇的肌黏膜瓣含有丰富的动脉血供，这表明这些皮瓣可能在活体犬类中存活。上唇肌黏膜瓣在单个临床病例中成功用于重建大型腭裂。
