Abstract
Background Management of cleft-related maxillary hypoplasia using conventional orthognathic surgery (CO) is considered classical treatment modality. However, there is a challenging risk of postsurgical relapse and potential velopharyngeal incompetence following maxillary advancement. The introduction of internal distraction osteogenesis (DO) opened a new perspective for the treatment of various skeletal anomalies, particularly for the patient with cleft lip and palate (CL/P) that has been established. DO permits for a progressive new bone formation accompanied by expansion of the surrounding soft tissue, which gives a better long-term stability of the reconstruction, lessening the risk of relapse. Some studies reported improved results with the use of DO over the CO and have reported a decrease in the skeletal relapse, while other studies did not report any significant difference in skeletal relapse of CL/P when using CO versus DO. 2.2 Objectives PICOTS P (Population): Non- growing cleft lip and palate patients with maxillary hypoplasia I (Intervention): Internal Distraction Osteogenesis of maxilla. C (Comparator): Conventional Orthognathic Surgery of maxilla. O (Outcomes): Primary and Secondary outcomes Types of outcome: (a)Primary Outcome: skeletal maxillary stability (b)Secondary Outcome: soft tissue changes and patient satisfaction regarding facial esthetics. S (study design): Systematic review and meta-analysis. T (Time): Studies with any period from 6 months postoperatively follow up
