RESUMEN
BACKGROUND/AIM: The World Oral Maxillofacial Trauma (WORMAT) project was performed to analyze the causes and characteristics of maxillofacial fractures managed in 14 maxillofacial surgery divisions over a 1-year period. METHODS: The following data were collected: age, sex, cause and mechanism of maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score (FISS), associated injury, day of trauma, timing and type of treatment, and length of hospitalization. Statistical analyses were performed using SPSS software. RESULTS: Between 30 September 2019 and 4 October 2020, 2,387 patients (1,825 males and 562 females [ratio 3.2:1], 47.6% aged 20-39 years [mean age 37.2 years, median 33.0 years]) were hospitalised. The main cause of maxillofacial fracture was road traffic accidents (RTA), which were statistically associated with male adults as like as assault, sport, and work (p<0,05). Half of the fractures involved the middle third of the face, statistically associated with fall and assault (p<0.05). Trauma in multiple locations was significantly associated with longer hospital stay (p<0.05). The mean length of hospitalization was 3.9 days (95% Confidence Interval 3.7-4.2). CONCLUSIONS: This prospective, multicenter epidemiological study confirmed that young adult males were the ones most commonly affected by maxillofacial fracture. RTAs and assaults are statistically associated with the adult population, while falls are associated with females and older population.

BACKGROUND/AIMS: Approximately 20% of patients with maxillofacial trauma are women, but few articles have analysed this. The aim of this multicentric, prospective, epidemiological study was to analyse the characteristics of maxillofacial fractures in the female population managed in 14 maxillofacial surgery departments on five continents over a 1-year period. METHODS: The following data were collected: age (0-18, 19-64, or ≥65 years), cause and mechanism of the maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injury, day of trauma, timing and type of treatment, and length of hospitalization. RESULTS: Between 30 September 2019 and 4 October 2020, 562 of 2387 patients hospitalized with maxillofacial trauma were females (24%; M: F ratio, 3.2:1) aged between 1 and 96 years (median age, 37 years). Most fractures occurred in patients aged 20-39 years. The main causes were falls (43% [median age, 60.5 years]), which were more common in Australian, European and American units (p < .001). They were followed by road traffic accidents (35% [median age, 29.5 years]). Assaults (15% [median age, 31.5 years]) were statistically associated with alcohol and/or drug abuse (p < .001). Of all patients, 39% underwent open reduction and internal fixation, 36% did not receive surgical treatment, and 25% underwent closed reduction. CONCLUSION: Falls were the main cause of maxillofacial injury in the female population in countries with ageing populations, while road traffic accidents were the main cause in African and some Asian centres, especially in patients ≤65 years. Assaults remain a significant cause of trauma, primarily in patients aged 19-64 years, and they are related to alcohol use.

BACKGROUND/AIMS: Paediatric maxillofacial trauma accounts for 15% of all maxillofacial trauma but remains a leading cause of mortality. The aim of this prospective, multicentric epidemiological study was to analyse the characteristics of maxillofacial fractures in paediatric patients managed in 14 maxillofacial surgery departments on five continents over a 1-year period. METHODS: The following data were collected: age (preschool [0-6 years], school age [7-12 years], and adolescent [13-18 years]), cause and mechanism of the maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injuries, day of the maxillofacial trauma, timing and type of treatment, and length of hospitalization. Statistical analyses were performed using SPSS software. RESULTS: Between 30 September 2019 and 4 October 2020, 322 patients (male:female ratio, 2.3:1) aged 0-18 years (median age, 15 years) were hospitalized with maxillofacial trauma. The most frequent causes of the trauma were road traffic accidents (36%; median age, 15 years), followed by falls (24%; median age, 8 years) and sports (21%; median age, 14 years). Alcohol and/or drug abuse was significantly associated with males (p < .001) and older age (p < .001). Overall, 474 fractures were observed (1.47 per capita). The most affected site was the mandibular condyle in children <13 years old and the nose in adolescents. The proportion of patients who underwent open reduction and internal fixation increased with age (p < .001). CONCLUSION: The main cause of paediatric maxillofacial fractures was road traffic accidents, with the highest rates seen in African and Asian centres, and the frequency of such fractures increased with age. Falls showed an inverse association with age and were the leading cause of trauma in children 0-6 years of age. The choice of treatment varies with age, reflecting anatomical and etiological changes towards patterns more similar to those seen in adulthood.

BACKGROUND/AIMS: The growth of the global elderly population will lead to an increase in traumatic injuries in this group, including those affecting the maxillofacial area, with a heavier load on health systems. The aim of this multicentric prospective study was to understand and evaluate the incidences, causes and patterns of oral and maxillofacial injuries in patients aged over 60 years admitted to 14 maxillofacial surgical departments around the world. METHODS: The following data were collected: gender, cause and mechanism of maxillofacial fracture, alcohol and drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injury, day of trauma, timing and type of treatment and length of hospitalization. Statistical analyses were performed using non-parametric and association tests, as well as linear regression. RESULTS: Between 30 September 2019 and 4 October 2020, 348 out of 2387 patients (14.6%), 197 men and 151 women (ratio 1.3:1; mean age 72.7 years), were hospitalized. The main causes of the maxillofacial fractures were falls (66.4%), followed by road traffic accidents (21.5%) and assaults (5.2%). Of the 472 maxillofacial fractures, 69.7% were in the middle third of the face, 28% in the lower third and 2.3% in the upper third. Patients with middle third fractures were on average 4.2 years older than patients with lower third fractures (95% CI 1.2-7.2). Statistical analysis showed that women were more involved in fall-related trauma compared with males (p < .001). It was also shown that road traffic accidents cause more fractures in the lower third (p < .001) and in the middle third-lower third complex compared with upper third (p < .001). CONCLUSIONS: Maxillofacial fractures in the elderly were more frequent in European and Australian centres and affected men slightly more than women. Falls were the leading cause of fractures, especially among women. The middle third of the face was most often affected, and conservative treatment was the most common choice for the management of such patients.

The aim of this study was to evaluate and discuss the long-term outcomes of patients with condylar osteochondroma managed through 3 different surgical techniques. Seven patients with condylar osteochondroma treated in the author's department from May 2012 to January 2019 were included in this retrospective study. Clinical evaluations (visual analogue scale for TMJ pain, jaw function, symmetry, and quality of life), maximum interincisal opening (MIO) and radiological findings were collected pre- and postoperatively. Other parameters assessed included tumour size and location; complications and follow-up. Radical condylectomy with immediate total joint alloplastic reconstruction was performed in 4 patients, local excision in 2 patients and low condylectomy with concomitant orthognathic surgery in 1 patient. During an average follow-up period of 40,8 months no clinical or radiographic signs of recurrence were found. Average MIO increased from 25,5mm to 39,5mm at the longest follow up, and all clinical evaluations were greatly improved. In conclusion, the described surgical techniques appear valuable in the treatment of condylar osteochondroma. Local excision is indicated in tumor involving less than half the surface of the condylar head; radical condylectomy with immediate alloplastic total joint reconstruction is indicated in gigantic lesion compromising the anatomical components and function of the joint. Orthognathic surgery procedures should be combined with tumor resection when correction of associated dentofacial deformities is indicated.

PURPOSE: The authors conducted a retrospective, multicenter study to investigate the differences in the fixation patterns, in terms of number and thickness of plates, between patients in whom a third molar (3M) was maintained or removed in the line of mandibular angle fractures. MATERIALS AND METHODS: The study was conducted in 6 European level I and II maxillofacial trauma centers. Data were collected on patients ≥ 16 years of age who underwent open reduction internal fixation (ORIF) for mandibular angle fractures (MAF) from 2008 to 2018, in whom a 3M in the fracture line was present and who had a follow-up duration of 6 months. The study population was divided into 2 groups: patients treated with ORIF in whom the 3M was maintained (group 1) and those treated with ORIF in whom the 3M was extracted (group 2) during treatment. The 2 groups were compared for differences in the internal fixation pattern, specifically in terms of the number and thickness of the plates. RESULTS: A total of 749 patients with 774 MAF were collected. A total of 1,050 plates were placed: 849 were ≤ 1.4 mm thick (80.9%) and 201 plates ≥ 1.5 mm thick (19.1%). 548 patients were treated with ORIF and 3M maintained (group 1), and 201 treated with ORIF and 3M extracted (group 2). Statistically significant differences were seen in the number of ≤1.4 mm plates between the 2 groups for single undisplaced/displaced MAF(P value ≤ 0.5) and for undisplaced/displaced angle + parasymphysis/body fractures (P-value ≤ 0.5). CONCLUSIONS: Analyses of data collected from 6 European maxillofacial centers indicated that the majority of surgeons of our sample perceived the MAF as being more unstable when removing the 3M during ORIF leading them to perform a rigid fixation in the angular region.

PURPOSE: The aim of this survey was to investigate the surgical management of bilateral mandibular angle fracture (BMAF) in Europe. METHODS: Data were collected from 2008 to 2018 on patients ≥ 16 years of age who underwent open reduction internal fixation (ORIF) for BMAF with a third molar in the fracture line. The study was conducted at 6 European trauma centers. The following data were recorded: sex, age, cause of the fracture, type of fracture (nondisplaced, displaced, comminuted), type of approach (intraoral, transbuccal, or extraoral), thickness of the plate (≤1.4 mm or ≥1.5 mm), number of plates, cause of plate removal, and third molar extraction status. RESULTS: 25 patients with BMAF (24 males, 1 female, 17 to 83 years old [mean: 28.2 years]) were collected. The main cause of BMAF was assault, and the main surgical approach was intraoral. The most common types of BMAF were displaced + undisplaced (11 patients), displaced + displaced (7 patients), undisplaced + undisplaced (6 patients), and comminuted + comminuted (1 patient). Osteosynthesis was performed with 2 ≤1.4 mm plates on 1 angular fracture and 1 ≤1.4 mm plate on the other fracture in 11 patients, 1 ≤1.4 mm plate on both angular fractures in 6 patients, 1 ≥1.5 mm plate on both fractures in 5 patients, and 2 ≤1.4 mm plates on both fractures in the remaining 3 patients. Out of 25 patients with BMAF, 7 third molars were extracted during ORIF. Among these patients, angular fracture fixation was performed in 3 cases with 1 ≥1.5 mm plate and in 4 patients with 2 ≤1.4 mm plates. CONCLUSIONS: This retrospective multicenter survey indicates a trend of treating with open reduction and rigid internal fixation at least 1 angular fracture of BMAF and those cases requiring extraction of the third molar in the line of fracture.
