Motor vehicle accidents-related maxillofacial injuries: a multicentre and prospective study.

Oral Surg Oral Med Oral Pathol Oral Radiol 2019 Sep 13;128(3):199-204. Epub 2018 Dec 13.

Department of Oral and Maxillofacial Surgery/Pathology, VU University Medical Center and Academic Centre for Dentistry Amsterdam (ACTA), Amsterdam, The Netherlands.

Objectives: The purpose of this European multicenter prospective study was to obtain more precise information about the demographic characteristics and etiologic/epidemiologic patterns of motor vehicle accidents (MVA)-related maxillofacial fractures.

Study Design: Of the 3260 patients with maxillofacial fractures admitted within the study period, 326 traumas were caused by MVAs with a male/female ratio of 2.2:1.

Results: The maximum incidence was found in Zagreb (Croatia) (18%) and the minimum in Bergen (Norway) (0%). The most frequent mechanisms were car accidents, with 177 cases, followed by motorcycle accidents. The most frequently observed fracture involved the mandible, with 199 fractures, followed by maxillo-zygomatic-orbital (MZO) fractures.

Conclusions: In all the 3 groups (car, motorcycle, and pedestrian), mandibular and MZO fractures were the 2 most frequently observed fractures, with some variations. The importance of analyzing MVA-related facial injuries and their features and characteristics should be stressed.

Intramuscular botulinum toxin injection additional to arthrocentesis in the management of temporomandibular joint pain.

Oral Surg Oral Med Oral Pathol Oral Radiol 2016 Oct 24;122(4):e99-e106. Epub 2016 May 24.

Center of Prosthodontics, Clinic of Dentistry, Tartu University Hospital, University of Tartu, Tartu, Estonia.

Objective: The aim of this study was to compare the effect of intramuscular injection of botulinum toxin (BTX-A) as an adjunct to arthrocentesis with the effect of BTX-A injections alone in the treatment of temporomandibular joint disorders (TMDs) with masticatory muscles tension.

Study Design: The clinical study included 20 TMD patients divided into 2 groups. The influence of daily activities on pain in the temporomandibular joint (TMJ) area was evaluated in both groups using the rating scale by List and Helkimo. Range of maximal interincisial opening (MIO) and joint pain as measured by the visual analogue scale (VAS) were examined to determine the clinical efficiency of the procedures before and after treatment. Group A consisted of 12 patients; they were treated with arthrocentesis and BTX-A injections in the temporal and masseter muscles. Group B consisted of 8 patients; they had only BTX-A injections in the same muscles as mentioned.

Results: In group A, VAS decreased significantly (P = .005), and MIO improved significantly (P < .005).

Conclusions: Arthrocentesis with BTX-A seems to affect the clinical outcomes with regard to MIO and VAS compared with the results when BTX-A only was used. BTX-A in combination with arthrocentesis improved the TMJ area symptoms.

European Maxillofacial Trauma (EURMAT) in children: a multicenter and prospective study.

Oral Surg Oral Med Oral Pathol Oral Radiol 2015 May 24;119(5):499-504. Epub 2014 Dec 24.

Department of Maxillofacial surgery, Stomatology Clinic, Tartu University, Tartu, Estonia.

Objective: The aim of this study is to present and discuss the results of a European multicentre prospective study about pediatric maxillofacial trauma epidemiology during a year.

Study Design: The following data were recorded: gender, age, etiology, site of fracture, date of injury. Of the 3396 patients with maxillofacial fractures admitted within the study period, 114 (3.3%) were children aged 15 years and younger, with a male/female ratio of 2.6:1. Mean age was 10.9 years. Most patients (63%) were aged 11-15 years.

Results: The most frequent cause of injury was fall (36 patients). Sport injuries and assaults were almost limited to the oldest group, whereas falls were more uniformly distributed in the 3 groups. The most frequently observed fracture involved the mandible with 47 fractures. In particular, 18 condylar fractures were recorded, followed by 12 body fractures.

Conclusions: Falls can be acknowledged as the most important cause of facial trauma during the first years of life. The high incidence of sport accidents after 10 years may be a reason to increase the use of mouthguards and other protective equipment. Finally, the mandible (and in particular the condyle) was confirmed as the most frequent fracture site.

Assault-related maxillofacial injuries: the results from the European Maxillofacial Trauma (EURMAT) multicenter and prospective collaboration.

Oral Surg Oral Med Oral Pathol Oral Radiol 2015 Apr 11;119(4):385-91. Epub 2014 Dec 11.

Department of Maxillofacial surgery, Stomatology Clinic, Tartu University, Tartu, Estonia.

Objective: The aim of this study is to present and discuss the demographic characteristics and patterns of assault-related maxillofacial fractures as reported by a European multicenter prospective study.

Study Design: Demographic and injury data were recorded for each patient who was a victim of an assault.

Results: Assaults represented the most frequent etiology of maxillofacial trauma with an overall rate of 39% and the values ranging between 60.8% (Kiev, Ukraine) and 15.4% (Bergen, Norway). The most frequent mechanisms of assault-related maxillofacial fractures were fists in 730 cases, followed by kicks and fists. The most frequently observed fracture involved the mandible (814 fractures), followed by orbito-zygomatic-maxillary complex fractures and orbital fractures.

Conclusions: Our data confirmed the strong possibility that patients with maxillofacial fractures may be victims of physical aggression. The crucial role of alcohol in assault-related fractures was also confirmed by our study.

European Maxillofacial Trauma (EURMAT) project: a multicentre and prospective study.

J Craniomaxillofac Surg 2015 Jan 22;43(1):62-70. Epub 2014 Oct 22.

Department of Oral and Maxillofacial Surgery/Pathology, VU University Medical Center and Academic Centre for Dentistry Amsterdam (ACTA), Amsterdam, The Netherlands.

The purpose of this study was to analyse the demographics, causes and characteristics of maxillofacial fractures managed at several European departments of oral and maxillofacial surgery over one year. The following data were recorded: gender, age, aetiology, site of facial fractures, facial injury severity score, timing of intervention, length of hospital stay. Data for a total of 3396 patients (2655 males and 741 females) with 4155 fractures were recorded. The mean age differed from country to country, ranging between 29.9 and 43.9 years. Overall, the most frequent cause of injury was assault, which accounted for the injuries of 1309 patients; assaults and falls alternated as the most important aetiological factor in the various centres. The most frequently observed fracture involved the mandible with 1743 fractures, followed by orbital-zygomatic-maxillary (OZM) fractures. Condylar fractures were the most commonly observed mandibular fracture. The results of the EURMAT collaboration confirm the changing trend in maxillofacial trauma epidemiology in Europe, with trauma cases caused by assaults and falls now outnumbering those due to road traffic accidents. The progressive ageing of the European population, in addition to strict road and work legislation may have been responsible for this change. Men are still the most frequent victims of maxillofacial injuries.
