A great challenge of rhinoplasty is the tip with insufficient projection or the hooked nose. Tip grafting is the standard method used to correct this. The open rhinoplasty technique provides exposure of nasal structures not afforded by the closed approach. We have used this approach to sculpt the nasal tip. Successful "unhooking of the hooked nose" by gaining tip projection has been achieved by completely replanting the medial crura. In the operation, the medial crura are freed in their entirety. The lateral alae of the lower cartilages are trimmed. The medial crura are then advanced dorsally until adequate nasal tip projection is obtained. They are secured to each other and to the septum in their new position with interrupted sutures. More tip definition can be obtained, if needed, by suturing the medial crura together near the tip. The dome can be sculpted to an appropriate width in a similar manner. This technique is advantageous because exact symmetry and positioning of the cartilages can be obtained under direct vision. It contours the tip structures to achieve more nasal tip projection, obviating the need for tip grafting. The technique is particularly useful in the patient with a low dorsum and acute nasolabial angle who will benefit from tip augmentation and elevation. The technique simultaneously thins the tip, adds nasal tip projection of 4 to 6 mm, and corrects the nasolabial angle. We have used this technique with good results in 15 patients. The technique and results were illustrated.
隆鼻术的一个巨大挑战是鼻尖突出不足或鹰钩鼻。鼻尖移植是纠正这一问题的标准方法。开放式隆鼻术能够暴露闭合式手术无法触及的鼻腔结构。我们采用这种方法来塑造鼻尖。通过完全重新植入内侧脚,成功实现了通过增加鼻尖突出度来“矫正鹰钩鼻”。在手术中,将内侧脚完全游离。修剪下侧软骨的外侧鼻翼。然后将内侧脚向背侧推进,直到获得足够的鼻尖突出度。用间断缝线将它们在新位置相互固定,并固定到鼻中隔上。如有需要,可通过在鼻尖附近将内侧脚缝合在一起获得更多鼻尖立体感。可以用类似的方式将鼻尖穹窿部雕刻成合适的宽度。该技术的优势在于能够在直视下实现软骨的精确对称和定位。它塑造鼻尖结构以获得更多的鼻尖突出度,从而无需进行鼻尖移植。该技术对于鼻背低平和鼻唇角锐利的患者特别有用,这些患者将从鼻尖增大和抬高术中获益。该技术同时使鼻尖变薄,增加4至6毫米的鼻尖突出度,并矫正鼻唇角。我们已将该技术应用于15例患者,效果良好。对该技术及结果进行了说明。
