[A statistical epidemiological study of cranio-maxillofacial trauma in the Friuli Venezia Giulia region].

Data corresponding to 17,247 subjects, admitted in Hospital of Friuli Venezia Giulia region, were analyzed in the period between 1984/2/28 and 1993/2/27. All data were selected for for diagnosis, sex, aetiology, age, diagnosis's priority, days of stay in Hospital and locality where the patients live. The results showed 69.31% of the patients were male (range 0-80 years) of 15-19 years (2,605 cases corresponding to 15.1%) and 20-24 years (2,448 patients, 14.2%). More frequently the traumatic pathology was related to injuries of the facial bones (72.22%) and of these 62.13% were fractures of the nasal bones. The major incidence of injuries was caused from unspecified nature's incidents (47.5%), followed by road accidents (31.2%), violence, work accidents and others. The evaluation of single years showed a decrease of traumas from 2,019 cases (1984-85) to 1,759 cases (1992-93), probably caused by traffic regulations. Variables and incidence of cranial-maxillofacial traumas were also examined.
