A multidisciplinary approach with several specialits allows a complete treatment for Cleft Lip and Palate. We show our experience in presurgical orthopedic treatment in these patients, their advantages, their problems and the results.
Since 1999 presurgical orthopedy has been applied to 12 patients (3 bilateral cleft lip and palate and 9 unilateral cleft lip and palate). This approach was applied when there was a long distance between the alveolar segments. A palate mould and the location of Latham's appliance have been made in the operating room under general anesthesia. The patients were controlled by the orthodoncist and Latham's appliance was removed when cleft lip was closed.
Latham's appliance was kept for 4-7 weeks with once a week controls until the distance between the maxillary segments was less than 1 mm; in bilateral cases of cleft lip and palate the premaxilla was moved between lateral segments. Then, lip closure and nasoplasty was made and, sometimes, an obturador was placed.
Latham's appliance permit to achieve a perfect alignment of alveolar segments decreasing the soft tissues tension and facilitating the lip surgery, thus, a better aesthetic and functional results can be achieved. A more anatomic position of palate can be made and easier future orthopedic treatments are possible.
多学科专家共同参与的方法能够对唇腭裂进行全面治疗。我们展示了我们在这些患者的术前正畸治疗方面的经验、其优势、存在的问题及结果。
自1999年起,术前正畸已应用于12例患者(3例双侧唇腭裂和9例单侧唇腭裂)。当牙槽突段之间距离较远时采用这种方法。在全身麻醉下于手术室制作腭托及放置莱瑟姆矫治器。患者由正畸医生进行检查,在唇裂修复时拆除莱瑟姆矫治器。
莱瑟姆矫治器佩戴4 - 7周,每周检查一次,直至上颌段之间的距离小于1毫米;在双侧唇腭裂病例中,前颌骨被移动至侧段之间。然后进行唇裂修复和鼻成形术,有时还会放置一个阻塞器。
莱瑟姆矫治器能够使牙槽突段完美对齐,降低软组织张力并便于唇裂手术,因此,可以获得更好的美学和功能效果。能够使腭部处于更符合解剖结构的位置,并且使未来的正畸治疗更易于进行。
