¿Son eficaces los conformadores nasales postoperatorios? una revisión sistemática"

Background and objective. Lip and nose symmetry are the goal of repair of unilateral cleft lip and different pre and postope-rative treatments have been developed with this purpose. The objective of this study was to perform a review of the li-terature to evaluate the effects of postoperative nasal conformers on cleft lip and palate patients. Methods. We conduct a systematic review of the literature for studies published until March 2021 to evaluate aesthetic effect using nasal conformers after primary cheilorhinoplasty in patients with cleft lip and palate. Results. We identified 6 studies for the final analysis, which included 195 patients. The overall study quality according to Oxford CEBM and Newcastle-Ottawa scale was low. Conclusions. The results obtained from this study provides that placement of postoperative nasal conformers did not improve nasal symmetry in patients with unilateral cleft lip and palate. Based on available scientific evidence, definitive conclusions about the effectiveness of these devices on nasal symmetry after unilateral cleft lip nose repair cannot be drawn.
