ObjectiveTo evaluate the impact of single-stage posterior vomerine ostectomy with premaxillary setback (PVPS) on craniofacial development in children with bilateral cleft lip and palate (BCLP) and a protuberant premaxilla.DesignRetrospective pilot study.SettingResource-limited outreach setting.Patients, ParticipantsFifty-two children were included: 22 with BCLP who underwent PVPS before 8 years of age and 30 age-matched non-cleft controls.InterventionsSingle-stage PVPS with bilateral gingivoperiosteoplasties, bilateral cleft lip repair, and primary rhinoplasty.Main Outcome Measure(s)Twenty-two cephalometric parameters assessed post-operatively; intergroup comparisons made using the Mann-Whitney U-test with post-hoc power analysis.ResultsOf 22 cephalometric variables, 16 showed no statistically significant differences between PVPS-treated and control groups, indicating minimal overall impact of PVPS on craniofacial growth. Significant differences were noted in SNA (P = .05), ANB (P = .02), N-A-Pog (P P P = .03), and HSTA (P < .01). These differences reflected localized or subtle growth effects rather than global craniofacial alterations.ConclusionsPVPS appears to preserve craniofacial growth in the preadolescent period in BCLP patients with a protruding premaxilla, with limited and localized impact on specific parameters. While not recommended when preoperative orthodontics is available, PVPS provides a valuable alternative in resource-limited settings by achieving adequate results, reducing psychosocial stigma, improving societal integration, and consolidating surgical interventions.
