PURPOSE: To evaluate the long-term skeletal stability after maxillary surgical advancement with conventional Le Fort I osteotomy in patients with cleft lip and palate by a systematic review of the published data. MATERIALS AND METHODS: Electronic databases, "gray literature," and reference list searches were conducted. The inclusion criteria were the stability of maxillary surgical advancement with conventional Le Fort I osteotomy fixed with plates and assessed at the post-treatment follow-up 1 year or more postoperatively in patients with cleft lip and/or palate. Full reports were retrieved from abstracts or titles that appeared to meet the inclusion criteria or lacked sufficient detail for immediate exclusion. Once full reports were collected, they were again reviewed, considering more detailed inclusion criteria for a final selection decision. A methodologic quality assessment tool was used. The quantity and quality of the obtained data precluded a meta-analytic approach. RESULTS: A total of 25 abstracts/titles met the initial search criteria, and 10 studies were finally selected. The overall methodologic quality scores were high for only 1 randomized clinical trial. After maxillary advancement with Le Fort I in patients with cleft lip and palate, the long-term horizontal relapse at the A-point was 20% to 30% in 4 studies and 30% to 40% in 3 studies. In addition, vertical relapse was more than 50% in 4 studies. The study judged as a high-quality study reported a 37% rate of horizontal relapse and a 65% rate of vertical relapse at the A-point. CONCLUSIONS: Current evidence suggests maxillary surgical advancement with conventional Le Fort I osteotomy in patients with cleft lip and palate appears to show a moderate relapse rate in the horizontal plane and a high relapse rate in the vertical plane.

[13], dans leur revue de la littérature de 2012, la récidive sagittale dans un sens de recul du maxillaire est de 20 a ` 40 % après une propulsion de moins de 8 mm. Quant a ` la récidive de la dimension verticale, cette revue de la littérature montre des récidives allant de 50 % a ` 65 %. "

    ABSTRACT: Patients with cleft lip and palate frequently develop dento-facial deformity requiring orthognatic surgery. The origin of this deformity is therapeutic and surgeons are currently trying to prevent this iatrogenicity. The maxillary dento-facial deformity in these patients is a retrognathia with infragnathia, associated with endognathia, obliquity of the occlusal plane, with deviation of the superior incisive midline in case of unilateral clefts. The difficulties in the treatment of these skeletal deformities are due to the palatal, labial, and pterygomaxillary scar tissue. Orthognathic surgery is most of the time bimaxillary with a 3-dimensional movement of the jaws including maxillary advancement. The aims of surgery are occlusal, esthetic, and functional improvement. The first step is gingivoperiosteoplasty (ideally performed during childhood), orthodontic treatment including, if necessary, transversal maxillary distraction to obtain enough space to replace the lateral incisor; extraction of premolars should be avoided if possible. Planning and performing the treatment are difficult for the orthodontist and for the surgeon. Maxillary advancement by distraction may be an interesting alternative to prevent partial relapse. Obtaining normal oro-facial functions are required for a stable result. These should be monitored after the primary treatment by the whole staff, surgeons, speech therapist, and orthodontists. Performing Le Fort 1 osteotomy is more difficult than in other patients because of scar fibrosis than needs to be released.

    ABSTRACT: Distraction Osteogenesis (DO) became an alternative for the treatment of severe craniofacial skeletal dysplasias. The rigid external distraction device (RED) is successfully used to advance the maxilla and all the maxillary-orbital-frontal complex (monobloc) in children, adolescents and adults. This approach provides predictable and stable results, and it can be applied alone or with craniofacial orthognathic surgical procedures. In the present article, the technical aspects relevant to an adequate application of the RED will be described, including the planning, surgical and orthodontic procedures.

    ABSTRACT: It has been debated whether the Le Fort III procedure using distraction osteogenesis (LFIII-DO) reduces the risk of postintervention relapse compared with conventional Le Fort III (LFIII) osteotomy in the correction of syndromic midfacial hypoplasia. Our objective was to evaluate the short- and long-term stability of the bony structures after midfacial advancement using conventional LFIII osteotomy versus LFIII-DO in patients with syndromic midfacial hypoplasia. We performed a systematic review of the published data. An electronic search of 10 databases was performed from their inception through June 2012. The reference lists of the relevant publications were also reviewed. Studies were considered for inclusion if they were longitudinal clinical studies with follow-up periods of at least 1 year after surgery (LFIII group) or at the end of the consolidation period (LFIII-DO group). Study selection, risk of bias assessment, and data extraction were performed in duplicate. The methodologic and clinical heterogeneity across the studies precluded combining the findings using meta-analyses. A total of 57 reports met the initial search criteria, and 12 reports were finally selected. The studies demonstrated a mean midfacial advancement of 8 to 12 mm in the LFIII group and 9 to 16 mm in the LFIII-DO group. For the LFIII group, horizontal short-term follow-up showed a maximal rate of relapse of 8.7 to 11.9% in 2 studies, with 1 study demonstrating a far more severe rate of maximal relapse of 50%. For the LFIII-DO procedure, the horizontal short-term relapse rate was 14.4% in 1 study, with the remainder demonstrating a rate of relapse of less than 10%. Moreover, 3 studies even showed additional advancement without any rate of relapse. Current evidence suggests that conventional LFIII and LFIII-DO techniques can effectively advance the midface forward in patients with syndromic midfacial hypoplasia and have good to excellent stability, with a mild rate of relapse. However, the LFIII-DO technique appears to achieve a greater amount of advancement with a lower rate of relapse compared with the conventional LFIII technique.
