Observation of the nasal bone anatomy has demonstrated a double S-curve configuration from the base of the pyriform aperture to the medial canthus. The most common method of osteotomy uses a curved osteotome or a chisel. The movement of either is facilitated by tapping with a mallet. With this method, frequent green-stick fractures, fragmentation, and other complications have been encountered. For the last 6 years, a dual plane, curved stainless steel blade has been used to accomplish low to high osteotomies. This gives a precise lateral transverse osteotomy without medial osteotomy being required. This technique allows the operator to produce a well-defined and precise lateral osteotomy with fewer potential complications and less postoperative swelling as well as improved patient comfort. In cases of secondary rhinoplasty or old nasal trauma, sites of previous fibrous union are able to be osteotomized with precisely controlled cuts, avoiding unpredictable fragmentation or fracture lines.
对鼻骨解剖结构的观察显示,从梨状孔底部到内眦呈现双S形曲线结构。最常见的截骨方法是使用弯形骨刀或凿子。通过用槌轻敲来辅助二者的操作。采用这种方法时,经常会遇到青枝骨折、碎裂及其他并发症。在过去6年里,一种双平面、弯形不锈钢刀片被用于完成从低位到高位的截骨术。这能实现精确的外侧横向截骨,而无需内侧截骨。该技术使手术者能够进行明确且精确的外侧截骨,潜在并发症更少,术后肿胀减轻,患者舒适度提高。在二次鼻整形或陈旧性鼻外伤的病例中,先前纤维愈合部位能够通过精确控制的切口进行截骨,避免不可预测的碎裂或骨折线。
