Objective: To compare orthognathic surgery and distraction osteogenesis in the management of maxillary hypoplasia in patients with cleft lip and palate, focusing on treatment outcomes, skeletal stability, relapse rates, and patient-centered results.
Methodology: A narrative review of the literature was performed using PubMed, Scopus, and Cochrane Library. Studies were included if they investigated maxillary advancement in cleft lip and palate patients and reported outcomes related to skeletal stability, relapse, complications, or patient satisfaction. Both original clinical studies and reviews were considered.
Results: Orthognathic surgery allows precise, immediate maxillary advancement and is generally suitable for mild to moderate hypoplasia, though relapse rates range from 10% to 30% in severe cases. Distraction osteogenesis provides gradual advancement, promoting soft tissue adaptation and lower relapse in severe hypoplasia or younger patients, but requires longer treatment time and careful device management. Both techniques improve facial aesthetics and function, with high patient satisfaction.
Conclusion: Both orthognathic surgery and distraction osteogenesis are effective for treating maxillary hypoplasia in cleft patients. Orthognathic surgery is preferred for moderate cases with immediate results, whereas distraction osteogenesis is advantageous for severe hypoplasia or growing patients due to lower relapse risk and gradual adaptation. Treatment should be individualized according to patient needs and clinical factors.
