简介：在大部分卡通片中，主角几乎都是完美的化身(当然Shrek除外)，而配角们却总有着这样那样的小毛病。然而小人物也可能成为大英雄，总是有那么几个小配角会不甘寂寞地跳出来，调皮捣蛋，插科打诨，抢尽了风头，也带来了欢笑。也许它们的存在就是为了告诉我们，如果你也是小人物，只要坚持做自己，总有一天你会此主角更光彩。

简介：AbstractSeptoplasty is widely used in the treatment of structural nasal obstructions, and it also has a good effect and a high degree of postoperative satisfaction. However, there a large number of structures demonstrate abnormalities related to structural nasal obstruction, including the external nose, maxilla, nasal cavity and paranasal sinus. Nasal septum deviation is only one signs of structural nasal obstruction and does not represent all possible structural abnormalities of the nasal cavity and its surrounding structure. Septoplasty is only performed to correct deviations of the nasal septum, which in many cases is obviously insufficient in restoring the symmetry of the nasal structure. Therefore, septoplasty alone is not suitable for the treatment of most structural nasal obstructions. Nasal ventilation expansion surgery, which typically covers more abnormal structural correction procedures than septoplasty, should be used when describing the treatment of structural nasal obstruction.
