Abstract – To evaluate the frequency and causes of dental and maxillofacial trauma in hospitalized patients. From January 1, 2000 to December 31, 2003, data from hospitalized trauma patients in a level 1 trauma center in Israel were analyzed according to age, gender, time, place, and cause of injury. Maxillofacial and tooth injuries were separated and further analyzed according to the above parameters. The analysis was based on data from the Israel Trauma Registry (ITR). Of all 14 040 trauma patients, 1038 (7.4%) involved maxillofacial or dental injuries. Common causes of injury were motor vehicle crashes (41%), falls (27%) and intentional injuries (23%). Fifty percent occurred on the street/road, 17% at home and 14% in public buildings. Surgery was required in 55.5% of all maxillofacial injuries. Males were hospitalized three times more than females, and young people, ages 19–28, were at greatest risk (30.2%). Oral and maxillofacial trauma is common, requiring dental health training for primary caregivers. 相似文献

Abstract – An evaluation of dental and maxillofacial trauma in a level 1 trauma center in Israel was carried out to assess the causes of trauma and the relationship between the injuries to the patient's age, gender and ethnicity. Analysis was based on data from the Israel Trauma Registry. Patients hospitalized in a level 1 trauma center from January 1, 2000 to December 31, 2005 were analyzed according to age, gender, time, place, ethnicity and cause of injury. Files of 22 558 trauma patients were reviewed. Maxillofacial and tooth injuries were separated and further analyzed according to the above parameters. Maxillofacial or dental injuries were observed in 1668 (7.4%) of the trauma patients, caused by motor vehicle accidents (39.2%), falls (30.9%), and intentional injuries (21.2%). Most occurred on the street/road (46.5%), at home (18.8%), and in public buildings (12.4%). Arab patients suffered more from vehicle accidents while Jewish patients presented more intentional injuries. Men were hospitalized three times more than women, and young people were at greater risk. The most frequent age of trauma was 19–28 years (27.6%). Ethnic differences were particularly noticeable for intentional injuries and vehicle accidents. This emphasizes that a larger percentage of the Arab population suffered from dental and maxillofacial injuries. Further dental health education and training for primary caregivers are warranted. 相似文献

Maxillofacial injuries are a significant cause of morbidity and demand meticulously planned treatment. The aim of this present multi-center study was to evaluate the occurrence of dento-alveolar and maxillofacial injuries over a 5-year period. A retrospective cohort study of data from the Israel Trauma Registry was conducted for the years 2000-2004. The registry includes all trauma patients admitted and hospitalized due to an injury. Of the 111,010 hospitalized trauma patients, 5886 (5.3%) were diagnosed with maxillofacial or dental injuries. The main causes of injuries for hospitalized trauma patients were falls (48.1%) and motor vehicle accidents (25.2%), while the major causes of facial and dental injuries were vehicle accidents (39.6%, 56.8%, respectively) and falls (32.1%, 26.7%, respectively). High-risk age groups for dental and facial trauma were 10-18 years and 19-28 years, respectively, while for other trauma, ages for the greatest risk ranged from 0 to 9 years and over 59 years. Males were injured two to three times more frequently than females. A better understanding of the etiology of maxillofacial and dental injuries and identifying the high-risk groups should lead to appropriate prevention programs and treatment methods. 相似文献

Maxillofacial and dental injuries are not uncommon. These injuries may cause morbidity and demand meticulously planned treatment. Part 1 of this study focused on the incidence of general trauma injuries, as well as facial or dental trauma. The aim of part 2 is to evaluate the severity and location of the dento-alveolar and maxillofacial injuries over 5 years. A retrospective cohort study was conducted based on data from the Israel National Trauma Registry. Patients admitted and hospitalized due to trauma injuries during the years 2000-2004, totaled 111,010 in which 5886 (5.3%) were maxillofacial or dental injuries. Most of these injuries were traffic-related (54.5%), followed by events at home (18.7%). Facial injuries combined with injuries to other organs involved occurred in 3721 (63.2%) of the patients. Most minor injuries were noted when no other organs were involved, while severe injuries were more common when multiple organs were involved. More than 25% of facial injuries required surgery. Meticulous epidemiologic studies are needed to support the leading role, extent, and severity of maxillofacial trauma. 相似文献

During a 33 month period, maxillofacial injuries resulting from terrorist attacks in Israel were compared with non-terror trauma maxillofacial injuries. Files of patients hospitalized from October 1, 2000 to June 30, 2003 were obtained from the Israel National Trauma Registry. Data were evaluated and compared with a hospitalized non-terror related trauma population within the same period. A literature survey was also conducted. Terror casualties totaled 1,811. In 493 patients with facial injuries, 322 had soft facial tissue injuries (excluding eyes and ears), and 104 had hard tissue injuries of the maxillofacial complex. A significantly higher prevalence was found in terror casualties (explosions and gunshots) compared with non-terror related casualties. Most suffered multiple injuries. Maxillofacial terror casualties experience a unique epidemiology, with more severe injuries and higher prevalence of soft and hard tissue injuries. Preparedness and awareness to the unique pattern of injuries are needed when terrorists strike. 相似文献

Abstract – Purpose: Pattern and aetiology of maxillofacial injuries varies from one country to another and even within the same country depending on prevailing socio‐economic, cultural and environmental factors. Various studies have been carried out in various countries to study the epidemiology and demographics of the maxillofacial injuries but the studies from India are few. Material and methods: Retrospective study was undertaken at Christian Medical College Ludhiana (India) from January 2006 to December 2009. Treatment records of the patients was checked and age, gender, aetiology of injury, associated injuries, maxillofacial fractures and treatment offered were recorded. Results: A total of 1075 fractures were recorded in 718 patients, ranging from 11 months to 85 years of age. Male:female ratio was 6.6:1. Maxillofacial injuries were most common in third decade of life. A total of 517 patients suffered injuries because of road traffic accident, 115 because of accidental fall and 67 because of interpersonal violence. A total of 184 patients had 221 associated injuries of which 56.1% head injuries, 29.0% orthopaedic injuries and 14.9% other injuries were present. Of 596 middle third fractures, 29.8% were managed conservatively; for 21.7% and 48.7% of fractures, closed reduction and open reduction were performed respectively. Of 479 mandibular fractures, 1.8% was managed conservatively; for 16.7% and 81.5% fractures, closed reduction and open reduction were performed respectively. Conclusion: Better socio‐economic status of people, increased vehicular movements and non‐implementation of road safety norms have increased road traffic accidents. Proper education of the people who are most commonly involved in the RTA can be one of the possible ways to reduce the maxillofacial injuries. 相似文献

Although cervical spine injury is rarely associated with maxillofacial trauma, it should be suspected when injuries above the clavicle occur, as suggested in the Advanced Trauma Life Support Manual. A retrospective study of 2482 patients with maxillofacial trauma, who were admitted to the Maxillofacial Surgical Division of Turin University between 1996 and 2006, conducted to identify concomitant fractures of the cervical spine and establish a treatment protocol. Twenty-one patients (0.8%), consisting of 17 males and four females ranging in age from 15 to 70 years, had amyelic cervical spine fractures. In 90% of the cases, the cervical spine injury was caused by a road accident. Cervical spine injuries were diagnosed using lateral x-rays in three cases and with computed tomography in the remaining patients. Although an association has been reported between mandibular fracture and cervical spine injury, we did not observe a preferential association between injuries of the upper third of the face and spinal injury. Cervical spine immobilization should never be removed until cervical spine injury has been excluded using a lateral x-ray of the cervical spine. In males with significant blunt craniomaxillofacial trauma caused by high-energy impact accidents such as car and motorcycle accidents, computed tomography is the radiologic examination of first choice to exclude cervical spine injuries. Lastly, the presence of a cervical spine injury did not result in modified or delayed treatment of maxillofacial fractures, with the exception of one patient who had a fracture of the odontoid process. 相似文献

PURPOSE: We sought to evaluate the frequency and distribution of maxillofacial injuries associated with all-terrain vehicle (ATV) collisions and to compare this with patients involved in motorcycle accidents over the same 5-year period at the University of Alabama at Birmingham.Patients and methods The records of all patients involved in ATV collisions who were admitted to the University of Alabama at Birmingham Trauma Center from January 1998 to January 2003 were reviewed. Age, gender, mechanism of injury, length of stay, Glasgow Coma Scale (GCS) score, maxillofacial injuries, Injury Severity Score (ISS), and maxillofacial Abbreviated Injury Scale (AIS) score were the factors considered for the study. These variables were also analyzed for patients involved in motorcycle collisions who sustained maxillofacial trauma. RESULTS: There were a total of 72 ATV collisions; 23 patients (32%) sustained maxillofacial injuries. The mean age was 31, and there were 59 males (82%) and 13 females (18%). The most common mechanism of injury was an ATV rollover. The warmer seasons and weekend days had the highest frequency of ATV trauma. Of the 23 patients who sustained maxillofacial injuries, the average maxillofacial AIS score was 2. The length of stay and GCS score were 8 days and 12, respectively, compared to 5 days and 15 in the nonmaxillofacial injury group. The most common maxillofacial fracture seen was a zygomaticomaxillary complex fracture (n = 8), followed by mandibular fractures (n = 6), and orbital floor blowout fractures (n = 5). Eighty-three percent of patients with maxillofacial injuries required an operative intervention during their hospitalization. The distribution of maxillofacial fractures in the ATV group was similar to that of an equivalent motorcycle group, but the frequency for the ATV group was higher (32% versus 8%). The length of stay for the motorcycle group was 11 days versus 8 days for the ATV group. The GCS scores, maxillofacial AIS scores, and ISS were similar between the 2 groups (12, 2, and 18, respectively). In patients who sustained maxillofacial fractures, neurologic injuries were the most frequent concomitant injury in the ATV group, whereas orthopedic injuries occurred more often in the motorcycle group. CONCLUSIONS: Maxillofacial injuries are common findings in ATV collisions. ATV patients with maxillofacial fractures have more neurologic impairment at admission and longer hospitalizations than patients sustaining motorcycle injuries. There needs to be an increase in the public health effort to educate individuals about the dangers of ATVs and to provide proper safety guidelines before the purchase of a vehicle. 相似文献

Abstract – The purpose of this study was to determine the occurrence and type of traumatic dental injuries after maxillofacial injuries as a result of Alpine skiing. During an 8‐year period (from January 1991 to December 1998) 7600 patients with facial injuries were registered at the Department of Oral and Maxillofacial Surgery, University of Innsbruck, Austria. Of 784 patients with skiing‐related facial injuries (524 males, 260 females) 326 (41.6%) sustained injuries to 639 teeth. The age groups predominantly affected were between 7 and 32 years. Luxation injuries occurred in 338 (53%) teeth, fractures accounted for 270 tooth injuries (42%), and only 35 (5%) were lost at the place of the accident. Of skiers with traumatic dental injuries 58% had concomitant soft tissue injuries, while 23.3% had associated facial bone fractures. The most common causes of injury were falls in 42% (329 patients) and collisions with other persons in 24.1% (189 patients). Being hit by one's own sports equipment (11%) was the third most common cause. Collisions with obstacles accounted for 9% and lift accidents for 5.6% of injuries. The probability of suffering dentoalveolar trauma during skiing varied depending on the injury mechanism. There was a 2–fold risk for dentoalveolar trauma when colliding with objects, a 3.5‐fold risk when hit by one's own equipment and a 8.5‐fold risk during lift accidents. Dental injuries occurred in about 2% of all injured skiers. Dental health professionals should be aware of the high incidence and the distribution of dental trauma and facial injuries caused by skiing. 相似文献

Major trauma is an important cause of mortality and morbidity worldwide. Mortality is high with rates over 10% commonly reported. We studied the epidemiology and aetiology of maxillofacial injuries in patients who presented with major trauma as recorded nationally by retrospectively analysing the database of the Trauma Audit Research Network from 2001 to 2015. All patients who had major trauma with associated maxillofacial injuries were included in the analysis. Of 104 645 patients recorded as having had major trauma during the study period, 22 148 (21.2%) had an associated maxillofacial injury. Most of them were male (74.2%), and the type of injury was usually blunt (97.5%). Road traffic collisions were the most common mechanism (44.1%), followed by falls of less than 2 m (21.6%). An associated serious head injury was more common in those who had a facial injury (81% compared with 60.6%, p < 0.0001). Nearly all the facial injuries (94%) were minor, or moderately severe. Maxillofacial injuries commonly present with major trauma but are rarely severe. A maxillofacial injury may indicate an increased likelihood of an associated head injury. 相似文献

Abstract – Introduction: Aetiology of oral and maxillofacial injuries in this country includes motorvehicle accident (MVA), fall, industrial accidents and others. Among these causes, MVA accident is the predominant cause of injury in Malaysia. Materials and methods: A retrospective record review was carried out using hospital records of all patients who sustained oral and maxillofacial injury at the Department of Oral Surgery, Seremban Hospital, Negeri Sembilan, Malaysia between 1998 and 2002. Information related to demographics, aetiology of trauma, vehicles involved in collision, location of injuries and treatment modalities were reviewed. Results: Two thousand nine hundred and eighty‐six patients sustained oral and maxillofacial injuries. Of these patients, 79.2% were men and the remaining were women. Among all the races, Malays had the highest involvement (50.6%) followed by Indians (24.5%), Chinese (19.6%) and others (5.3%). There were statistically significant results on the association of aetiology and the ethnic groups, in the age group of 30 years or less and male gender (P < 0.001). The most common injury was the soft‐tissue injury followed by dental and dentoalveolar injuries and bony fracture. Among all facial fractures, 66.3% were managed conservatively, 13% were treated surgically and 19.7% did not have any intervention. In relation to dental and dentoalveolar injuries, 64.8% had treatment in the form of splinting, restorations or dental extraction. The rest of the patients (35.2%) were referred to their dentists or did not have any active treatment at Seremban Hospital. Conclusion: Most of the dental and facial injuries in Seremban Hospital were caused by MVA and were predominantly managed using conservative methods. 相似文献

A systematic literature search was conducted (through April 2017), using Web of Science, PubMed and Virtual Health Library, manual reference list, and grey literature searches. The quality of the studies was evaluated using the Newcastle‐Ottawa Quality Assessment Scale. The meta‐analysis was performed using R software. A total of 30 studies was included in this review. From a total of 25 studies included in the meta‐analysis, the prevalence of oral and maxillofacial injuries among epileptic subjects was 19%. Among the epileptic patients who suffered some type of injury due to epileptic seizures, 52% had facial soft tissue injuries (95%CI: 28‐75%), 18% suffered dental trauma (95%CI: 11‐29%), and 12% (95%CI: 4‐28%) suffered maxillofacial fractures. Epileptic patients were more likely to have oral and maxillofacial injuries than healthy individuals (OR: 5.22, 95%CI: 2.84‐9.36) and subjects with psychogenic nonepileptic seizures (OR: 2.77, 95%CI: 1.28‐5.99), but not than patients with special needs (OR: 2.45,95%CI: 0.95‐6.31). 相似文献

PURPOSE: We sought to determine the etiology and pattern of motorcycle-related maxillofacial injuries among intracity road users in Nigeria. PATIENTS AND METHODS: We conducted a prospective review of all patients presenting at the maxillofacial surgery units of the Obafemi Awolowo University Teaching Hospital Ile-Ife and Usmanu Dan Fodiyo University Teaching Hospital Sokoto with motorcycle-related injuries. RESULTS: One hundred seven patients were included in the study. A significant male preponderance was observed (P = .002). Overall, the peak age incidence was 20 to 29 years, whereas female patients had a peak age incidence of 10 to 19 years. Victims were mostly riders (50.5%) but none of them was a female. While 8.4% of accidents occurred on motorcycles with more than one pillion passenger, none of the victims reported using a crash helmet. Mechanism of accident was mostly head-on collision (39.2%). The injuries sustained were predominantly soft tissue injuries or in combination with bone injury. Bone and dental injuries were attributed mostly to falls. Facial bone injuries occurred mostly in the mandible (64 of 104). A symmetric distribution of injuries was observed in the upper, middle, and lower thirds of the face, but the middle third had the highest injury sites while the upper third had the least. CONCLUSIONS: Motorcycle-related maxillofacial injuries among Nigerians affect males predominantly. The injuries sustained have a symmetric distribution and were mostly soft tissue injuries in isolation or in combination with bony injuries. The middle third of the face is most vulnerable. Mandatory use of safety helmets and education of cyclists on the appropriate number of pillion passengers are imperative to minimize the morbidity and mortality associated with motorcycle accidents. 相似文献

BACKGROUND: Trauma has been identified as a major public health problem in Australia. Maxillofacial trauma constitutes a significant proportion of trauma, although epidemiological studies in Australia are few. The purpose of this study was to assess the prevalence and the epidemiological pattern of maxillofacial trauma occurring in major trauma patients. METHODS: Data were obtained from the Victorian State Trauma Registry, which included all major trauma patients in Victoria. All data relating to maxillofacial trauma defined according to Abbreviated Injury Scale and International Classification of Diseases codes from 1 July 2001 to 30 June 2004 were selected. Data collected included demographic and injury details, and operative procedures carried out. RESULTS: Sixteen per cent of major trauma patients sustained maxillofacial trauma. The highest frequency of injuries occurred in the 15-24 years age group. More males were affected than females (3:1). The majority of injuries were due to transportrelated causes (69 per cent) and occurred mostly on roads, streets or highways (70 per cent). Falls were the cause of 15 per cent of injuries, 10.5 per cent of these injuries were fatal while 20.7 per cent needed rehabilitation. The most common type of bony injury was a fractured maxilla. CONCLUSION: The need for preventive strategies to be reinforced has been highlighted as transport-related injuries remain high especially in the younger age groups. 相似文献

Introduction
The aim of the study was to analyze the incidence, characteristics, and correlations between maxillofacial fractures and dental injuries in patients who were treated at a first-level trauma center in a metropolitan center in northwest Italy in the last 11 years.Material and methods
Between January 1, 2001 and December 31, 2011, 2,110 patients with maxillofacial fractures were admitted. Only dentulous patients with complete clinical records who presented with associated dental injuries were included in this study. Data on the age, gender, mechanism of injury, damaged tooth, type of dental injury, site of facial fractures, and concomitant injuries were recorded.Results
On the whole, 267 patients (13.1 %), mainly males aged 20–29 years, presented with 759 dental injuries associated with maxillofacial fractures, especially following motor vehicle accidents. The maxillary teeth, most often the anterior elements with decreasing involvement from the incisors to the molars, were the teeth most frequently damaged overall. The main types of dental trauma in patients with maxillofacial fractures were luxations and dental fractures.Discussion
Our findings show that patients with mandibular fractures were statistically and significantly associated with dental injury, and the teeth in the upper jaw were the most frequently injured teeth, exhibiting mainly luxations and crown fractures. Confirmation of the predominant impact site in patients with dental injuries associated with maxillofacial fractures comes from the 177 lacerations noted in the chin and lip regions in 267 patients. 相似文献16.

Pediatric maxillofacial trauma is a challenge for surgeons. There are no completely defined protocols, and sometimes, the initial management could be complex. The aim of this research was to perform a retrospective study to analyze the pattern and treatment of maxillofacial fractures in pediatric and adolescent patients. We reviewed the clinical records of 2986 patients treated at the Oral and Maxillofacial Surgery Division of Piracicaba Dental School between 1999 and 2008. Seven hundred fifty-seven patients were younger than 18 years and were divided into 3 groups according to age; the age and sex of the patients, etiology, fractures and associated injury, treatment, and complications were evaluated. Five hundred thirty boys (70.01%) and 227 girls (29.99%) were treated for injuries with major prevalence in adolescents. The most common injury causes were bicycle accidents (29.06%) and falls (28.40%). The mandible was the most fractured bone (44.8%); associated injuries were lacerations of the soft tissue and dental trauma. Surgical treatment was performed in 75 cases (30%) with minor complications (10% of surgical patients). We conclude that maxillofacial trauma in child is associated to fall and bicycle accidents; the mandible is more affected than other maxillofacial structures, and frequently, nonsurgical treatment is performed. 相似文献

The purpose of this study was to evaluate the incidence of trauma victims of age 60 years and older who required maxillofacial intervention. The study analyses the pattern of injuries and the various factors that predict the treatment plan of these patients. A retrospective study was carried out in 1820 trauma patients who reported to the Sri. Ramachandra Dental College and Hospital and required maxillofacial intervention, over a period of 5 years (October 2000 and September 2005). Of the total trauma victims, 185 patients were found to be aged 60 years more. In the majority of the patients, the injury was due to road traffic accidents (79.4%). Males (72.4%) sustained more injuries than females (27.6%). Soft tissue injuries were seen in 49.1% of the patients, while 14% had mandibular fractures. People in their early 60s were injured more often than their older counterparts. The findings of this study highlight the present situation with regard to maxillofacial trauma in patients aged 60 years and older and its management in this part of the country. 相似文献

The purpose of this study was to determine the occurrence and type of traumatic dental injuries after maxillofacial injuries as a result of Alpine skiing. During an 8-year period (from January 1991 to December 1998) 7600 patients with facial injuries were registered at the Department of Oral and Maxillofacial Surgery, University of Innsbruck, Austria. Of 784 patients with skiing-related facial injuries (524 males, 260 females) 326 (41.6%) sustained injuries to 639 teeth. The age groups predominantly affected were between 7 and 32 years. Luxation injuries occurred in 338 (53%) teeth, fractures accounted for 270 tooth injuries (42%), and only 35 (5%) were lost at the place of the accident. Of skiers with traumatic dental injuries 58% had concomitant soft tissue injuries, while 23.3% had associated facial bone fractures. The most common causes of injury were falls in 42% (329 patients) and collisions with other persons in 24.1% (189 patients). Being hit by one's own sports equipment (11%) was the third most common cause. Collisions with obstacles accounted for 9% and lift accidents for 5.6% of injuries. The probability of suffering dentoalveolar trauma during skiing varied depending on the injury mechanism. There was a 2-fold risk for dentoalveolar trauma when colliding with objects, a 3.5-fold risk when hit by one's own equipment and a 8.5-fold risk during lift accidents. Dental injuries occurred in about 2% of all injured skiers. Dental health professionals should be aware of the high incidence and the distribution of dental trauma and facial injuries caused by skiing. 相似文献

Abstract – This study reports on the etiology and environment where dental injuries occurred and assesses the relationship between dental trauma, socio-economic status and dental caries experience. A population-based, matched case-comparison study was undertaken in 30 schools in two Ontario communities. Dental hygienists calibrated in the use of the Dental Trauma Index (DTI) screened 2422 children aged 12 and 14 years using DTI and Decayed, Missing and Filled Teeth indices. Cases ( n = 135) were children with evidence of dental injury. Controls ( n = 135) were children randomly selected after screening and matched with cases according to age and gender. Questionnaires were mailed to parents and children. Prevalence of dental injury was 11.4%, mostly minor injuries 63.7% (enamel fracture not involving dentin), affecting one upper central incisor (70.4%). The mean age at the time of dental injuries was 9.5 years (SD = 1.49; range: 6–13 years). Dental trauma most often occurred among boys at school because of falls or while playing sports. The relationship between dental injuries and the socio-economic indicators chosen was not statistically significant. However, a statistically significant direct relationship ( P < 0.001) was shown between increased caries experience and dental injuries. This should focus attention on possible common-risk factors such as health-related behavioral problems that may affect both dental disease and dental injuries. 相似文献

PURPOSE: This study emphasizes the significance of maxillofacial injuries in skiing accidents, correlating injury mechanisms and patterns, by evaluating a large population of maxillofacial injuries over a 6-year period. PATIENTS AND METHODS: Between 1991 and 1996, of 5,623 patients showing oral and maxillofacial injuries, 1,859 were sports-related. Records of 579 patients with 882 incidents of oral and maxillofacial injury due to skiing were reviewed and analyzed according to age, sex, type of injury, cause of accident, location, and frequency of fractures. Additionally, the five main injury mechanisms were analyzed. RESULTS: The oral and maxillofacial injuries in 10.3% of all trauma patients, or 33% of all sports-related trauma patients, were due to skiing. A total of 310 patients (53.5%) had facial bone fractures, 236 patients (40.8%) suffered from dentoalveolar trauma, and 336 patients (58%) showed soft tissue injuries. Five major causes and mechanisms of injury existed, namely, 263 falls (45%); 135 collisions with other skiers (23%); 70 individuals struck by their own ski equipment (12%); 46 collisions against stationary objects (8%); and 34 lift-track accidents (6%). Sex distribution showed an overall male-to-female ratio of 1.9:1.0, but varied depending on the injury mechanism. The age distribution ranged from 2 to 81 years. CONCLUSION: The results of this study show the high incidence of oral and maxillofacial injuries due to skiing accidents. Depending on the mechanism of injury, different patterns occur. Facial bone fractures are more likely in collisions with other persons, falls, and collisions with stationary objects, whereas dentoalveolar trauma is more common when persons are struck by their own ski equipment, or when accidents on lift-tracks occur. 相似文献
