Introduction:
This study aimed to evaluate the influence of age, sex, and facial growth patterns on the maturation stage of midpalatal sutures.
Methods:
We selected 90 total skull cone-beam computed tomography scans and divided them into the following 3 groups: brachyfacial (n = 30), mesofacial (n = 30), and dolichofacial (n = 30). These groups were determined using Ricketts VERT 3-dimensional cephalometric analysis. All patients were aged ≥18 years and were divided into those aged ≥30 years and >30 years. The maturational stage of the median palatine sutures was determined by evaluating the central transverse axial dimension in the maxillary-mandibular palate. Maturational stages were classified as A, B, C, D, and E.
Results:
Of the 90 images reviewed, 55 (61.1%) were female patients, and 35 were male patients (38.9%). The age of patients ranged from 18 to 59 years, with 55 patients aged <30 years (61.1%) and 35 aged ≥30 years (38.9%). Regarding the maturational stages, 3.3% of brachyfacial, 6.7% of mesiofacial, and 16.7% of dolichofacial subjects (P = 0.032) were classified as stages B and C.
Conclusions:
The patients' facial patterns were found to be a significant signal for the maturation stage of midpalatal sutures. Adult dolichofacial patients are the most likely to have stage B and C.
