“腭裂根治术”经临床实践证明,有很多优点,是一种有实用价值的修复方法,然而它也有一定的不足。比如,当腭腱膜被剪断后,腭部肌肉附丽即发生改变,进而使腭部肌肉功能受到一定程度的影响;该处鼻腔粘膜被剪断后,由于两侧粘骨膜瓣后退,以至鼻腔面出现菱形创面,日后菱形创面疤痕形成,收缩,使软腭重新变短,组织变硬,严重影响语言功能。此外,这种手术方法也较为复杂,手术颇感费时。为此,我们设计了L形骨瓣术式,以弥补其不足。近年来我们采用本法修复先天性腭裂35例,现将临床病例总结分析如下: “Cleft palate radical surgery” proved by clinical practice, there are many advantages, is a practical method of repair, but it also has some shortcomings. For example, when the palatal aponeurosis is severed, the palatal muscle changes with attachment to the palate, which in turn causes the palatal muscle function to be affected to a certain extent. After the mucosa of the nasal mucosa is cut, the mucoperiosteal flap on both sides retracts and the surface of the nasal cavity appears Diamond-shaped wounds, diamond scar scar formation, contraction, the soft palate to re-shorten the hardened tissue, seriously affecting the language function. In addition, this surgical method is also more complicated, the operation is quite time-consuming. To this end, we designed the L-shaped flap surgery to make up for its deficiencies. In recent years, we use this method to repair 35 cases of congenital cleft palate, the clinical cases are summarized as follows:
