The Impact of Presurgical Infant Orthopedics on Oronasal Fistula Rates Following Cleft Repair: A Meta-Analysis

Background: Presurgical infant orthopedics (PSIO) techniques were introduced to improve the outcomes achieved when treating children with complete cleft lip and palate. The effect of PSIO on the incidence of postoperative fistulae has never been reliably demonstrated. We conducted a meta-analysis to assess the effectiveness of PSIO in reducing postoperative fistulas in patients with complete cleft lip and palate. Methods: A search of the PubMed and Embase databases was performed to identify relevant articles that included primary palate repairs of patients with unilateral or bilateral complete clefts, reported the incidence of postoperative fistulae, and explicitly stated if PSIO was used. Details including author, number of subjects, use of PSIO, and fistula rate were cataloged. Results: A review of the PubMed database yielded 1135 unique citations, and Embase yielded 507 articles. Review of these yielded 15 studies, comprising 1241 children, which met inclusion criteria. The overall rate of oronasal fistula development was 7.09%. The average fistula rate for studies using PSIO was 5.93% versus 9.71% in the non-PSIO group. This difference was not statistically significant (P = .34). Conclusions: The use of PSIO prior to cleft lip and palate repair provides multiple benefits related to facial and nasal form and is supported by a body of literature. The effect of PSIO on the incidence of postoperative fistulae has received less attention in the literature. Our meta-analysis of the available literature does not provide evidence to support the premise that the use of PSIO affects the incidence of fistulae after cleft palate repair.
