■为了记录使用阔筋膜移植物成功手术重建复合鼻颌和上唇缺损,狗的钛网和口角轴型皮瓣。
■一只估计2岁的雌性完整混种狗出现了复合(硬和软组织)鼻腋窝缺损,怀疑是由化学烧伤引起的。体格检查发现流鼻涕,暴露的双侧上颌骨和鼻骨,有空气运动的鼻腋窝瘘,左上颌犬齿的内在变色。软组织病变从鼻平面向远端延伸到左眼的内侧眼角,并从右上颌骨延伸,包括左侧上颌唇的整个厚度损失。头部的计算机断层扫描图像显示上颌骨慢性骨髓炎,颧骨和鼻骨伴鼻颌瘘,左上颌前磨牙有许多裸露的根部。计划进行分阶段的外科手术以解决牙列和鼻腋窝缺损。第一个程序包括拔除牙周受损的左上颌前磨牙,双侧上颌尖牙的标准根管治疗。第二种程序包括清除非重要的软组织和硬组织,并在虚拟手术计划后对鼻腋窝缺损进行手术重建。术后5个月进行的头部计算机断层扫描显示骨缺损的大小减小以及鼻炎的消退。
■此案例证明了使用软组织移植物组合的可行性,钛网,和轴型皮瓣治疗鼻腋窝缺损。这种缺陷会导致慢性鼻炎,感染,不适,和长期发病率。此病例报告提供了一种新颖而实用的方法来管理狗的鼻腋窝区域缺陷。
UNASSIGNED: To document the successful surgical reconstruction of a composite nasomaxillary and superior labial defect using a fascia lata graft, titanium mesh and angularis oris axial pattern flap in a dog.
UNASSIGNED: An estimated 2-year-old female intact mixed-breed dog was presented with a composite (hard and soft tissue) nasomaxillary defect, suspected to be caused by a chemical burn. Physical examination revealed nasal discharge, exposed bilateral maxilla and nasal bone, nasomaxillary fistula with air movement, and intrinsic discoloration of the left maxillary canine tooth. The soft tissue lesion extended from the nasal planum rostrally to the medial canthus of the left eye distally and from the right maxillary bone to include a full thickness loss of the left maxillary labium laterally. Computed tomographic images of the head showed chronic osteomyelitis of the maxilla, zygomatic and nasal bones with nasomaxillary fistula and numerous exposed roots of the left maxillary premolars. Staged surgical procedures to address the dentition and nasomaxillary defect were planned. The first procedure consisted of the extraction of periodontally compromised left maxillary premolars, and standard root canal therapy of bilateral maxillary canine teeth. The second procedure consisted of debridement of the non-vital soft and hard tissues and surgical reconstruction of the nasomaxillary defect after virtual surgical planning. Head computed tomography performed 5 months post-operatively revealed a decrease in the size of the osseous defect as well as the resolution of rhinitis.
UNASSIGNED: This case demonstrates the feasibility of using a combination of soft tissue graft, titanium mesh, and axial pattern flap in managing nasomaxillary defects. Such defects can lead to chronic rhinitis, infection, discomfort, and long-term morbidity. This case report provides a novel but practical approach for managing defects in the nasomaxillary region in dogs.
