【摘要】 目的　探讨腭裂手术切口设计的改良对术后腭咽闭合不全的影响。方法　将收治的 90例腭裂患者随机分为A、B两组。所有病例均采用改良“腭裂根治术”术式。切口设计 :(1)A组软腭至悬雍垂裂隙边缘切口均偏向口腔侧 2～ 4mm ;将软腭组织不等份剖开 ,鼻腔侧多于口腔侧。 (2 )B组软腭至悬雍垂裂隙边缘切口均位于边缘顶端 ,将软腭口腔侧、鼻腔侧软组织等份剖开。结果　A组术后悬雍垂均不同程度向上后偏移 ,B组术后悬雍垂均偏向口腔侧且下垂 ,A组术后语音质量、鼻漏气量显著优于B组。结论　腭裂手术切口设计的改良对改善腭咽闭合不全有显著效果。更多还原

【Abstract】 Objective To study the effect of post-operation velopharyngeal function due to a modified incision of cleft palate (CP) operation.Methods Ninety CP patients were divided into two groups at random.All patients were treated with improved “Linberg Operation”.The designs of incision were different :(1) In group A,through soft palate to uvula,the incision of edge of cleft were partial to a side of mouth cavity 2-4mm; (2) In group B,the incision of edge of cleft were located the top of the edge.Results Two weeks post-operation the uvulas of group A were partial to nasal cavity,but the uvulas of group B were partial to mouth cavity.Conclusions The modified incision of CP operation is remarkable in the improvement of VPI postoperation.更多还原
