A variety of surgical methods have been described to repair wide cleft palate; they are all challenging to perform and yield consistently good results. The islandized mucoperiosteal flap, the technique described in the present article, is very versatile because it can close palatal defects of any size without undue tension. Moreover, it provides adequate length and mobility of the soft palate with improved speech and feeding functions without fistula formation.
Between 2005 and 2011, 36 patients with wide cleft palate were operated on using islandized mucoperiosteal flaps. This technique involves dissection of the neurovascular bundle from the mucoperiosteal flaps for approximately 1 cm and dissecting the muscle from the posterior edge of the hard palate with intravelar veloplasty. The flaps subsequently become freely mobile in all directions. It can move medially to close palatal defects of any size without tension. In addition, posterior or backward mobilization lengthens the soft palate and renders it freely mobile.
All repairs were successful, with no complications and no patients requiring secondary procedures. All patients regained normal feeding function three weeks postoperatively. All patients showed normal nasal resonance of speech except for two (three and five years of age) who experienced abnormal resonance in the form of open nasality that required regular speech therapy for six months. There was significant improvement and no secondary procedures were required for either.
A technical modification for closure of wide palatal clefts is introduced. The islandized mucoperiosteal flap, which is a very versatile technique, can close cleft palates of any width without tension, lengthens the soft palate and renders it freely mobile for proper speech functions. Using this technique, good speech and feeding function with no complications were achieved.
已有多种手术方法用于修复宽大腭裂;这些方法实施起来都颇具挑战性,且难以始终取得良好效果。本文所描述的带蒂黏骨膜瓣技术具有很强的通用性,因为它能够无过度张力地关闭任何大小的腭部缺损。此外,它能提供软腭足够的长度和活动度,改善语音和进食功能,且不会形成瘘管。
2005年至2011年期间,对36例宽大腭裂患者采用带蒂黏骨膜瓣进行手术。该技术包括从黏骨膜瓣上分离神经血管束约1厘米,并通过腭内肌成形术从硬腭后缘分离肌肉。随后,瓣可在各个方向自由活动。它可向内侧移动以无张力地关闭任何大小的腭部缺损。此外,向后或向后移动可延长软腭并使其自由活动。
所有修复均成功,无并发症,且无需患者进行二次手术。所有患者术后三周恢复正常进食功能。除两名患者(3岁和5岁)出现开放性鼻音形式的异常共鸣,需要进行6个月的常规语音治疗外,所有患者语音的鼻共鸣均正常。这两名患者也有显著改善,且均无需二次手术。
