应用单侧岛状颊肌黏膜瓣和双反向双Z成形术修复宽大腭裂

目的应用单侧岛状颊肌黏膜瓣加双反向双Z成形术修复较宽大的腭裂,延长软腭,不做牙槽弓内侧松弛切口,腭部无骨性创面裸露和瘢痕形成,以减少或避免对上颌骨和牙槽弓生长发育的影响。方法应用改良的双反向双Z成形术延长软腭,裂缘蒂的口腔侧黏骨膜瓣翻转关闭鼻腔侧的裂隙,一侧岛状颊肌黏膜瓣修复腭部口腔侧创面,牙槽弓内侧不做松弛切口。结果应用该法共治疗36例,2例出现了腭瘘,其余伤口愈合良好,软腭延长显著,无组织瓣坏死、伤口感染、张口困难、面神经损伤等并发症发生。随访8例患者,均获得完善的腭咽闭合功能。结论一侧岛状颊肌黏膜瓣与双反向双Z成形术联合应用修复较宽大的腭裂,既延长了软腭,又避免了腭部骨性创面裸露、瘢痕形成而影响上颌骨和牙槽弓生长发育,是一项安全可靠的手术。

Unilateral buccinator myomucosal island flap with double opposing Z-plasty for wider palatal cleft repair

Objective To explore a method to repair larger cleft palate and lengthen soft palate without oral palate raw surface and scar formation, reduce the effect on maxilla and dental arch development. Methods A modified doable opposing Z-plasty was used to lengthen soft palate and the nasal palate was closed by using large turn-over mucoperiosteal flaps on the oral surface of the junction of the hard palate and soft palate, oral raw surface on the palate was closed by a buccal myomucosal island flap. Results Thirty-six palates have been repaired by this procedure, all of which had satisfactory results without flap necrosis, infection, difficulties in opening mouth and facial nerve injury except two post-operative fistulas. Eight patients were followed up and all display complete velopharyngeal closure. Conclusions Using unilateral buccinator myomucosal island flap with doable opposing Z-plasty to repair wider palatal cleft can get a satisfactory soft palate lengthening. At the same time it can avoid bone surface exposing and scar formation ; it is a safe and reliable procedure.
