Abstract
The success of the orthopaedic treatment is closely related to the patient's skeletal maturation. This study aimed to evaluate the midpalatal suture (MPS), the zygomaticomaxillary suture (ZMS) maturation, and the closure degree of the spheno-occipital synchondrosis (SOS) in patients of different age groups. The presence of a correlation between these parameters and the palatal dimensions was also verified. The study was based on computed tomography images of 314 patients between 7 and 30 years of age with no orthodontic treatment history. The images were retrieved from the archive of the Radiology Department of Bezmialem Vakif University Hospital and divided into six groups according to the patient's age: 7-10, 11-13, 14-16, 17-20, 21-25, and 26-30 years. The maturation scores of ZMS, SOS, and MPS were determined, and palatal thickness and length were recorded. The data were analysed by using Statistical Package for Social Sciences for Windows 22.0. A positive relationship was found between SOS closure degree and MPS/ZMS maturation (MPS-ZMS: r = 0.816, MPS-SOS: r = 0.736, ZMS-SOS: r = 0.868, P = 0.000). The degrees of ZMS and MPS maturation were significantly increased as the SOS closure degree increased. The MPS maturation score was significantly lower in patients with a short and thick palate (MPS-palatal thickness: r = 0.405, MPS-palatal length: r = 0.387, P = 0.000). A positive correlation indicated the simultaneous progress in the maturation of the SOS, MPS, and ZMS. Moreover, the ANS-PNS length increase was found to be correlated with the increase of the MPS, ZMS, and SOS maturation scores. In contrast, a negative correlation was observed between the palatal thickness and the maturation stage of these structures.
