Background and Objective. The three mean features of the Pierre Robin sequence are micrognatia, airway obstruction and feeding problems, and the cleft palate may be associated. The cleft palate could be a prognosis factor in the final outcomes of the airway desobstruction during the jaw distraction. Our aim is to analyze if the cleft palate affects the final outcomes of the airway desobstruction in patients with jaw distraction, assessing the relationship between the maxillomadibular overjet and the cleft palate in the osteogenic distraction. Methods. We performed a prospective randomized study with patients between 2015 and 2017 in the Plastic Surgery Department of the Pediatric Hospital S.A.M.I.C. Juan P. Garrahan, Buenos Aires (Argentina). There were 31 patients with Pierre Robin sequence (57% boys and 43% girls), aged between 3 and 90 days, and they all had jaw distraction; 80.6% of patients had a cleft palate associated. Results. From the comparative analysis we obtained that if the severity of the maxillomandibular overjet wasn´t taken into account, there wasn´t difference between the analyzed groups. But, it the overjet was 7 mm or more, patients with cleft palate associated had les jaw distraction failure for the airway desobstruction and had better final outcomes. Conclusions. Patients with Pierre Robin sequence treated with jaw distraction for the airway desobstruction with a maxillomandibular overjet of 7 mm or more, had les treatment failure with p < 0.01.
