Changes in the pattern of fractures of the maxillofacial skeleton.

This study reports on two groups of patients who sustained maxillofacial fractures and were treated at the Department of Oral and Maxillofacial Surgery, Nijmegen, The Netherlands. It spans the periods 1 January 1960 31 December 1974 (1379 patients) and 1 January 1975 31 December 1987 (1324 patients). The changes in the pattern of maxillofacial fractures (e.g. localization and frequency, etiology, age and sex distribution, associated injuries) are discussed. The striking reduction of "road traffic accidents" and the increasing influence of "violence" and "sports" are remarkable.

[Epidemiology of facial injuries].

Epidemiological studies of maxillofacial trauma are numerous in the literature, but as a general rule their results are applicable to the investigated cohort only. Nevertheless, major differences in pattern of maxillofacial fractures have been reported between these studies. The longitudinal Nijmegen study (period 1960-1987) describes changes in the pattern of maxillofacial fractures for the Dutch situation. Traffic accidents still are the major cause of maxillofacial trauma, but the contribution of violent crimes and sports is rising. In addition, alcohol abuse as a factor in maxillofacial trauma has increased from 3% to 12% between 1960 and 1987. The current Dutch and international registration and classification systems need consent to allow for comparison of the results. Such systems should include ranking according to etiology, means of transport and age. Insight in the pattern of accidents, including maxillofacial trauma, will result in better ways of prevention of such accidents.

Ankylosis of the temporomandibular joint.

With the aid of 22 cases of mandibular ankylosis, the classification, aetiology, radiography, clinical symptoms and the operative procedures are discussed. By means of condylectomy (four patients), or a condylotomy (14 patients) or a horizontal ostectomy in the ascending ramus (performed in two patients with a relapse of condylotomy) in which a triangular bone fragment is removed in the dorsocaudal region, bone contact is prevented during mouth-opening. Considering the number of relapses (three of the 18 operated patients) the results as compared with those in the literature may be described as satisfactory.

The different patterns of fractures of the facial skeleton in four European countries.

A series of 1,420 Dutch patients with facial fractures was compared with series from three other European countries. Special attention is paid to the patterns of the facial fractures and the cause of those injuries. The majority of the fractures in all four countries were caused by traffic accidents. The age of the Dutch patients at the time of accident as well as the localization of the mandibular fractures differed from the ages and localizations of the patients in the other three countries. Manifold associated injuries occurred in combination with facial fractures. The need for treatment of facial fractures in well-equipped centers is important and cooperation with other specialiies is very often necessary.
