Subtotal septal reconstruction is a surgical technique used to reconstruct severe septal deviations that are not easily repaired using less invasive methods. Patients with identifiable septal fractures across the caudal or dorsal segments of the L-strut are good candidates. These patients may present with deformities such as the deviated nose or saddle nose. Adequate autologous cartilage is needed to reconstruct the septum. The deviated segments of the nasal septum are removed and then reconstructed by replacing the caudal septum with a straight piece of septal cartilage fixated to the nasal spine. The bilateral extended spreader grafts fixated to the remnant dorsal strut is then fixed to the caudal septal replacement graft to reconstitute the L-strut. In some cases, the dorsal strut may overlap the caudal portion of the L-strut to complete the repair. Care must be taken in setting nasal length, projection, rotation, and supratip break. If these parameters are not set very carefully deformity may ensue. Other potential complications include change in the upper lip smile or a crease forming in the upper lip when the patient smiles. This is a complex technique and must be performed with special care to avoid deformity.
鼻中隔部分重建术是一种外科技术,用于重建严重的鼻中隔偏曲,而这些偏曲使用侵入性较小的方法不易修复。在L形支柱的尾段或背段有可识别的鼻中隔骨折的患者是合适的手术对象。这些患者可能会出现诸如鼻偏曲或鞍鼻等畸形。重建鼻中隔需要足够的自体软骨。去除鼻中隔的偏曲段,然后用一块直的鼻中隔软骨替代尾侧鼻中隔并固定于鼻棘,以此进行重建。将双侧延伸撑开移植片固定于残余的背侧支柱,然后固定于尾侧鼻中隔替代移植片,以重建L形支柱。在某些情况下,背侧支柱可能与L形支柱的尾侧部分重叠以完成修复。在设定鼻长、鼻突度、鼻旋转度和鼻尖上区转折时必须谨慎。如果这些参数设定不非常仔细,可能会导致畸形。其他潜在并发症包括上唇微笑改变或患者微笑时上唇出现皱纹。这是一项复杂的技术,必须格外小心地进行操作以避免畸形。
