Maxillary distraction osteogenesis vs Orthognathic surgery (conventional Le Fort I osteotomy): Midfacial soft tissue changes (facial profile landmarks: pronasale, subnasale, stomion superius, labrale superius)
- Population
- Adolescents or adults (15 years or older) with an established diagnosis of complete cleft lip and alveolar process, or complete unilateral or bilateral cleft lip and palate (involving the alveolar process); non-syndromic, requiring surgical correction of maxillary hypoplasia
- Intervention
- Maxillary distraction osteogenesis
- Comparison
- Orthognathic surgery (conventional Le Fort I osteotomy)
- Outcome
- Midfacial soft tissue changes (facial profile landmarks: pronasale, subnasale, stomion superius, labrale superius)
Maxillary distraction osteogenesis showed no clear difference in midfacial soft tissue changes (facial profile landmarks: pronasale,… compared with orthognathic surgery (conventional Le Fort I osteotomy); GRADE not reported.

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
