There is little research which determines whether septoplasty affects nasal projection.
To assess the effect of various septoplasty (submucous resection, SMR) techniques on nasal tip projection in a fresh cadaver model.
The nasal tip projection was measured on 6 fresh cadaver heads and compared postoperatively after a sequence of submucous septoplasty maneuvers. Five different septoplasty techniques were performed in the same sequence on each cadaver. After each technique, measurements were performed.
Removal of a central square piece of quadrangular cartilage resulted in a loss of projection in 3 in 6 (50%) heads, with average loss of 7.76%. Removal of additional cartilage along the bony cartilaginous junction resulted in no loss of projection. Removing more septum along the floor resulted caused a change loss in nasal projection in 1 in 6 (17%) cadavers. Removing the remaining septum, except for the L-strut resulted in a loss of projection in 2 in 6 (33%) heads with an average percent change in tip projection of 9.08%. Swinging door technique resulted in a loss of projection in 1 cadaver (17%), with loss of 6.25%. All 6 cadavers experienced loss of nasal projection. When all maneuvers were taken in total, there was a statically significant average decrease in projection of 8.93% (range, 5.00-13.04%, p = 0.008).
Primary septoplasty carries a risk of nasal tip projection, with certain maneuvers carrying higher risk.
关于鼻中隔成形术是否会影响鼻尖突出度的研究甚少。
在新鲜尸体模型中评估各种鼻中隔成形术（黏膜下切除术，SMR）技术对鼻尖突出度的影响。
测量了 6 个新鲜尸体头颅的鼻尖突出度，并在一系列黏膜下鼻中隔成形术操作后进行了术后比较。在每个尸体上，以相同的顺序进行了 5 种不同的鼻中隔成形术技术。在每种技术之后，都进行了测量。
切除 5 个头颅的中隔方形软骨会导致 3 个头颅（50%）的突出度丧失，平均损失 7.76%。沿着骨性-软骨性结合部切除更多的软骨不会导致突出度丧失。沿着底部切除更多的鼻中隔会导致 1 个头颅（17%）的鼻尖突出度改变，6 个尸体中有 2 个（33%）的鼻尖突出度改变，平均鼻尖突出度改变百分比为 9.08%。除 L 型支柱外，切除剩余的鼻中隔会导致 2 个头颅（33%）的突出度丧失，平均鼻尖突出度改变百分比为 9.08%。旋转门技术会导致 1 个头颅（17%）的突出度丧失，损失 6.25%。所有 6 个尸体都经历了鼻尖突出度的丧失。当所有操作加起来时，平均突出度下降有统计学意义（范围，5.00-13.04%，p=0.008）。
原发性鼻中隔成形术会导致鼻尖突出度的丧失，某些操作会带来更高的风险。
