聚-DL-乳酸可吸收医用生物膜修复硬腭裂隙的临床观察

Repair of cleft hard palate with absorbable membrane of poly-DL-lactic acid: A clinical report

目的 :修复硬腭裂隙 ,观察由聚 DL 乳酸 (PDLLA)制成的可吸收医用膜植入硬腭裂隙后的局部变化及临床效果 ,为进一步的临床应用提供依据。方法 :选择 2 .67～ 12 .83岁的腭裂患者 3 2例 ,于软腭及悬雍垂裂修复同期剖开硬腭裂隙、植入可吸收医用膜并予以固定 ,术后定期随访 ,了解手术时间、术后并发症、可吸收医用膜色泽、质地的变化、局部组织生长及创口愈合情况。结果 :所有手术均顺利完成 ,术后患者软腭及悬雍垂创口愈合良好 ,无穿孔与裂开 ;硬腭部植膜区创口周围组织沿医用膜向中心生长 ,创口逐步缩小 ,术后 12周完全由新生软组织关闭。追踪观察 6个月 ,局部组织较为平滑 ,与周围正常组织色泽基本相同 ,形态相近。结论 :可吸收医用膜用于硬腭裂隙修复 ,手术操作简单、实用、可行 ,临床效果肯定 ,可选择性推广应用。

Objective:To study the effects of poly-DL-lactic acid(PDLLA) biomembrane in the repair of cleft hard palate. Methods:Thirty-two cleft palate patients, age 2.67 to 12.83 years old, were treated. The traditional surgical method was used to close the cleft soft palate, and the PDLLA biomembrane was implanted into the surgical gap between the periosteum and bone at the hard palate and fixed with suture to close the cleft hard palate. Clinical follow-up was conducted for 6 months.Results:Operations on all 32 patients were completed successfully.The average surgical time was not prolonged, and post-operative complication was not increased. Wound healing of soft palate, uvula and hard palate was uneventful with no incidence of fistula or dehiscence. Conclusion: PDLLA absorbable biomembrane can be used to repair cleft hard palate.
