This study evaluated the midpalatal suture maturation stages in 11 to 15 years old subjects by using cone beam computed tomography (CBCT) images. Considering that the rapid maxillary expansion has a high success rate at this age, we seek to identify the sutural maturation status in those patients in order to use it as a comparison parameter for RME prognosis in older patients. Sample consisted of 84 subjects, with ages ranging from 11 to 15 years old (40 males and 44 females), classified by using a midpalatal suture evaluation method (A, B, C, D and E). The measurement error was evaluated by kappa tests. Stage A was only observed in a 11 year old female subject. Stage B was observed at all ages, however presented its higher prevalence until the age of 13 (11 years old: 30.8%; 12 years old: 33.3%; 13 years old: 41.7%) and to a lesser extent in 14 and 15 subjects (6.7% and 11.8% respectively). Stage C was the most prevalent in all evaluated ages (11 years old: 61.5%; 12 years 51.9%; 13 years 50.0%; 14 years 53.3%; 15: 35.3 %). Stages D and E showed a low prevalence (13.1% and 10.7% respectively). The results obtained in this study, showing a major prevalence of C stage, suggests that conventional RME performed in subjects aged over 15 years old, would probably present a good enough prognosis, justifying this approach when the midpalatal suture maturational status indicates the C stage or less
