鼻畸形

鼻畸形是唇裂的主要伴发畸形,是唇裂质量不可忽视的内容。有研究表明,由于唇裂胚胎鼻软骨囊发育障碍,鼻软骨和鼻中隔生长缓慢,造成鼻软骨结构异常且组织量不足。单侧唇裂鼻畸形表现为患侧鼻翼坍塌、外展、下垂,鼻小柱短小、偏移,鼻翼基底凹陷,严重时伴有鼻中隔弯曲。完全性双侧唇裂鼻畸形最为严重,因上颌骨分离、鼻底组织缺如,导致鼻小柱发育障碍,鼻尖低平,鼻翼呈水平外展。唇裂鼻畸形的修复时机仍是一个有争议的问题。有的学者主张在修复唇裂时同期修复鼻畸形;持反对意见者认为如此可能幼儿的鼻软骨支架,对鼻发育造成不利的影响。近年来似乎有更多的人倾向于支持同期对严重的唇裂鼻畸形进行修复或复位,而不是放任异位的组织在原来的状态下自由生长使畸形加重。文献报道的唇裂鼻畸形的修复方式和所达到的效果不尽相同,其主要原则是适当游离鼻翼软骨,恢复其正常位置;延长鼻小柱,恢复鼻孔正常形态。唇裂鼻畸形的同期修复不是一样容易的工作,特别

请阅读  Passage 1,完成第  21~25小题 。Passage 1First two hours, now three hours-this ishow far in advance authorities are recommending people show up to catch adomestic flight, at least at some major U.S. airports with increasingly massivesecurity lines.Americans are willing to toleratetime-consuming security procedures in return for increased safety. The crash ofEgyptAir Flight 804, which terrorists may have downed over the Mediterranean Sea,provides another tragic reminder of why. But demanding too much of airtravelers or providing too little security in return undermines public supportfor the process. And it should: Wasted time is a drag on Americans ' economicand private lives, not to mention infuriating.Last year, the Transportation SecurityAdministration (TSA) found in a secret check that undercover investigators wereable to sneak weapons-both fake and real-past airport security nearly everytime they tried. Enhanced security measures since then, combined with a rise inairline travel due to the improving economy and low oil prices, have resultedin long waits at major airports such as Chicago ' s O ' Hare International. Itis not yet clear how much more effective airline security has become-but thelines are obvious.Part of the issue is that the governmentdid not anticipate the steep increase in airline travel, so the TSA is nowrushing to get new screeners on the line. Part of the issue is that airportshave only so much room for screening lanes. Another factor may be that morepeople are trying to overpack their carry-on bags to avoid checked-baggagefees, though the airlines strongly dispute this.There is one step the TSA could take thatwould not require remodeling airports or rushing to hire: Enroll more people inthe PreCheck program. PreCheck is supposed to be a win-win for travelers andthe TSA. Passengers who pass a background check are eligible to use expectedscreening lanes. This allows the TSA to focus. on travelers who are higherrisk, saving time for everyone involved. The TSA wants to enroll 25 millionpeople in PreCheck.Ithas not gotten anywhere close to that, and one big reason is sticker shock:Passengers must pay $85 every five years to process their background checks.Since the beginning, this price tag has been PreCheck ' s fatal flaw. Upcomingreforms might bring the price to a more reasonable level. But Congress shouldlook into doing so directly, by helping to finance PreCheck enrollment or tocut costs in other ways.The crash of EgyptAir Flight 804 is mentioned to_____.  .
