Although surgical treatment protocols for cleft lip and palate patients have been established, many patients still have some soft tissue defects after complete healing from surgical interventions. These are excess soft tissue, high attached fraena and firmed tethering scares. These soft tissue defects resulted shallowing of vestibule, restricted tooth movement, compromised periodontal health and trended to limit the maxillary growth. The aim of this case report was to present a method of correcting soft tissue defects after conventional surgery in cleft lip and palate patient by using combined laser surgery and orthodontic appliance.
A bilateral cleft lip and palate patient with a clinical problem of shallow upper anterior vestibule after alveolar bone graft received a vestibular extension by using CO laser with ablation and vaporization techniques at 4 W and continuous wave. A customized orthodontic appliance, called a buccal shield, was placed immediately after surgery and retained for 1 month to 3 months until complete soft tissue healing. The procedures were performed 2 episodes. Both interventions used the same CO laser procedure. The first treatment resulted in partial re-attachment of soft tissue at surgical area. The second laser operation with the proper design of buccal shield providing passive contact with more extended flange resulting in a favorable outcome from 1 year follow up. Then the corrective orthodontic treatment could be continued effectively.
The CO laser surgery was a proper treatment for correcting soft tissue defects and the design of buccal shield was a key for success in molding surgical soft tissue.
尽管唇腭裂患者的外科治疗方案已经确立,但许多患者在手术干预完全愈合后仍存在一些软组织缺陷。这些缺陷包括多余的软组织、附着过高的系带和变硬的牵拉瘢痕。这些软组织缺陷导致前庭变浅、牙齿移动受限、牙周健康受损,并倾向于限制上颌骨生长。本病例报告的目的是介绍一种通过联合激光手术和正畸矫治器来纠正唇腭裂患者传统手术后软组织缺陷的方法。
一名双侧唇腭裂患者在牙槽骨移植后出现上前庭浅的临床问题,采用4W连续波的CO激光消融和汽化技术进行前庭扩展。术后立即佩戴定制的正畸矫治器,即颊屏,保持1至3个月,直至软组织完全愈合。该过程分两期进行。两次干预均采用相同的CO激光手术。第一次治疗使手术区域的软组织部分重新附着。第二次激光手术配合设计合理的颊屏,使其与更宽的翼缘被动接触,1年随访结果良好。然后可以有效地继续进行正畸矫治。
CO激光手术是纠正软组织缺陷的合适治疗方法,颊屏的设计是手术软组织塑形成功的关键。
