一、概述腭裂修补术的目的一是恢复正常的解剖形态,闭合鼻腔和口腔间的裂隙,使食物不至从口腔漏入鼻腔;另一更重要的目的恢复患者的发音功能。前者一般容易做到。但后者目前仍处在研究改进之中。根据国内外文献报导,仍有20—40％的病例不能成功,其中10％比较严重。腭裂病人其所以语言含胡不清并带有浓重的鼻音,是因为“腭咽闭合”不全使气流从鼻腔窜出。所以要求腭裂参补后,病人能有一个足够长度而且活动良好的软腭,发音时软腭才能正常的活动。达到正常“腭咽闭合”。
First, an overview of the purpose of cleft palate repair one is to restore normal anatomy, the closure of nasal and oral cracks, so that food can not leak from the mouth into the nasal cavity; another more important purpose to restore the patient's pronunciation function. The former is generally easy to do. But the latter is still in research and improvement. According to domestic and foreign literature, there are still 20-40% of the cases can not be successful, of which 10% more serious. Cleft palate patients so its language is unclear and with a thick nasal tone, because the “velopharyngeal closure” incomplete flow of air from the nasal passages. Therefore, after the request of cleft palate, the patient can have a sufficiently long and well-behaved soft palate, the soft palate can be normal activity. To reach the normal “velopharyctomy.”
