Clinical-Epidemiological Study of a Cohort of 35 Patients with Craniosynostosis.

Craniosynostosis is a congenital anomaly defined as early ossification of the cranial sutures. It is a rare pathology worldwide, implicitly also in our country, with a prevalence of 1:2100-1:2500. However, it represents a condition with potentially severe complications in terms of patient functionality. At the same time, not much research has been done in this field. Thus, it was considered useful to conduct a study on the epidemiology of craniosynostosis in Bihor county. The present study had the following objectives: updating epidemiological data; analysis of the clinical data of the study group; identification of risk factors in the occurrence of the disease; evaluating the prospects for a genetic approach to the disease, including genetic testing and genetic counseling. This is a retrospective cross-sectional study. Data from a cohort of 35 patients were collected using the database which were made available by the Bihor Regional Center for Medical Genetics. Only patients with imaging-confirmed craniosynostosis in the last three decades were included in the study. Most patients were diagnosed in the age range of one month - one year, the mean being 197 days. The most frequently affected suture was the sagittal suture (60%) and the least affected one the metopic suture (5%). Combined lesions were present in three cases. The majority (75%) of cases were isolated craniosynostosis, with the remaining 25% being diagnosed in the context of a genetic syndrome (most frequently Apert syndrome). Throughout the three explored decades, a significant increase in the number of cases was observed. The most commonly affected groups included male patients, those from rural areas, those born after year 2000, especially from 2011 to the present. Most cases were isolated craniosynostosis. Heredo-collateral antecedents were insignificant. Three risk factors were present, including male sex, maternal smoking during pregnancy and advanced parents' ages. Complications of the disease were rare and a minority of patients benefited from surgical treatment. Genetic counseling is an important component of disease prevention and should be offered as soon as possible.
