To repair orbital medial wall fractures, otorhinolaryngologists often use the silicone sheet technique by inserting an inverted U-shaped silicone sheet into the middle meatus after the removal of fractured bones, and packing gauze inside the silicone sheet for several days to fix the shape of the medial wall. However, this method does not sufficiently reduce the orbital content.
To describe the surgical procedure to repair medial wall fractures using nasal septal cartilage as the reconstructive material.
First, endoscopic septoplasty is performed. Although the correction of the septal deviation is performed to secure the operative field, the nasal septal cartilage, except the L-strut is resected simultaneously. After septoplasty, the fractured bones of the lamina papyracea are removed from the herniated orbital contents, and then the orbital contents can be reduced without resistance by pushing laterally. Subsequently, the cartilage is inserted beneath the fracture edges of the orbital medial wall with great care to avoid entrapping the orbital soft tissue and extraocular muscles.
The cartilage can be placed appropriately along the medial wall of the orbit.
This technique enables to repair most cases of orbital medial wall fractures using the endoscopic endonasal approach alone without alloplastic implants.
为修复眶内侧壁骨折,耳鼻喉科医生常采用硅胶片技术,即在去除骨折骨片后,将倒U形硅胶片插入中鼻道,并在硅胶片内填塞纱布数天以固定内侧壁形状。然而,这种方法不能充分减少眶内容物。
描述使用鼻中隔软骨作为重建材料修复内侧壁骨折的手术方法。
首先,进行内镜下鼻中隔成形术。虽然进行鼻中隔偏曲矫正以确保手术视野,但同时切除除L形支柱外的鼻中隔软骨。鼻中隔成形术后,从疝出的眶内容物中去除纸样板的骨折骨片,然后通过向外侧推挤可无阻力地减少眶内容物。随后,小心地将软骨插入眶内侧壁的骨折边缘下方,以避免夹住眶软组织和眼外肌。
软骨可沿眶内侧壁适当放置。
该技术仅通过鼻内镜经鼻入路即可修复大多数眶内侧壁骨折病例,无需植入异体材料。
