Paper text:
a suitable administration is important to recreate and reproduce the structure , profile , form and function of uninjured status .
mandible is the main portable bone of the facial skeleton , and there has been a considerable upsurge in trauma and fracture in a majority of cases . in case if mandible fractures are not handles properly , that may prompt unfavorable outcome both cosmetically and functionally . the incidence of infection secondary to mandibular fractures ranges from 0% to 30% , resulting in significant sequelae . a 5 years study by gutta et al .
was conducted to assess the causes of the complications associated with the surgical treatment of mandibular fractures at an academic tertiary hospital .
the outcomes of gutta study reported that the use of antibiotics did not decrease the incidence of infections .
however , smokers and patients with systemic medical conditions had a greater risk of complications .
furthermore , a slight delay in surgical repair was not related to an increased complication rate . a study by czerwinski et al .
showed that the delay of mandibular fracture treatment > 3 days does not significantly increase infection risk . on the other hand , repair should occur promptly after the injury . a study by pham - dang et al .
stated that the most maxillofacial fractures involve the mandible , and there is an increasing trend in treating these fractures by osteosynthesis without intermaxillary fixation .
although treatment delays in the operative management of mandible fractures are often unavoidable , antibiotic prophylaxis associated with dental hygiene care can be indicated to prevent postoperative infections .
however , there is an increasing trend in falls as a cause of fracture , especially in female patients , consistent with the increasing trend in presentation of older people .
fewer studies have investigated the effectiveness of waiting time from presentation to accident and emergency until surgical intervention for patients with mandible fractures on the rate of infection and postoperative complications .
there is presently no strong evidence for either acute or delayed treatment of mandibular fractures in order to minimize healing complications ; new studies including a substantial number of cases treated on an acute basis are very much needed .
primary aim of this study was to evaluate the effectiveness of early treatment of mandibular fractures upon healing and postoperative complications .
the null hypothesis : early or delayed treatment of mandibular fractures has no effect in reducing or increasing the postoperative complications .
this study has been conducted using clinical data of patients attending the newcastle general hospital , uk for the management of mandibular fractures .
the retrospective clinical study lasted for 6 months included 91 patients ( 1460 years ) , who attended during weekdays 08.3017.00 ( treated at maxillofacial operating theater ) and evenings ( after 17.00 ) and weekends ( treated at trauma operating theater ) .
patients presented with various types of fracture ( single fracture , bilateral fracture , condyle fracture only , or multiple ) required open reduction and internal fixation of fractured mandibles were included .
the data were recorded including : date of visit , hospital number , age and gender .
the patient 's relevant medical history was to be considered in relation to the patient 's suitability for general anesthesia .
patients were classified into three groups according to the time utilized from admission to operative intervention ( < 24 [ treated within 24 h ] , < 72 [ treated within 72 h ] and 72 [ treatment took longer than 72 h ] ) .
different mechanisms of injury were also considered in relation to time consumed to treat patients .
common postoperative complications such as numbness , malocclusion and infection were recorded at 1 week and 4 weeks after patient 's discharge date .
a two group t - test with a 0.01 two - sided significance level was applied , and comparison between the groups was made using non parametric tests at a significance level of 0.01 .
patients needing urgent treatment should be treated within 72 h ( maxillofacial surgery ward ) .
the risk of infection has not been observed to increase by delaying the fracture treatment more than 72 h. so as to have the capacity to offer better treatment , administration and forethought to these patients it crucial to study the nature of trauma and its different perspectives and categories , sort and sort them appropriately .
this study was based on collecting information from 93 patients notes who were attending the newcastle general hospital , uk ( maxillofacial surgery department ) for the management of mandibular fractures over the period of 6 months .
the majority of patients ( > 90% ) were male patients [ figure 1 ] and presented with four major types of mandibular fractures .
the simple ( single or line fracture ) was the main type contributing 52.69% of total cases , followed by bilateral fractures ( 39.78% ) .
condylar and multiple fractures contributed only 7.53% whereas only one patient ( 1.08% ) reported condylar fractures .
patient distribution on the basis of gender and type of mandibular fractures the average time the patient took from incident to admission to the hospital was 11.20  0.68 h and there was no significant difference for incidence happened during the weekend or weekdays [ figure 2 ] .
time to treatment from the point of admission was 31.50  3.83 h during week days that has been significantly more than patients attending the hospital at weekends or nights .
similar trend was observed for total summative time from the incident to treatment analysis [ figure 2 ] .
the treatment procedure took a prolonged time ( 57.15  5.05 h ) for patients attending during working hours compared to patients attending over the weekends [ figure 2 ] . considering the potential cause of injuries , alcohol abuse and related assault remain the most common cause ( 61% all reported within 3 days of injury ) followed by interpersonal violence / assault that accounted for 22% [ figure 3 ] .
the fall and road traffic accidents ( rtc ) accounted for 11% and 7% respectively .
patients with mandible fractures related to rtc have higher median time to treatment from admission to operative intervention than other present complaints [ p < 0.05 , figure 3 ] .
a record of time to treatment for mandibular fracture patients attending the hospital during office hours and out of office hours relationships of fracture etiology and respective time to treatment for patient reporting mandibular fractures ( road traffic cases ) in terms of postoperative complications , a follow up of 4 weeks was recorded [ figure 4 ] .
about 45% patient did not report any post - operative complication in 4 weeks follow up time .
whereas 40% of patients with fractured mandible reported numbness after 1 week however it was reduced to 22% in 4 weeks follow up .
the third main complication was malocclusion that was developed in 17% and reduced to just 9% in later follow up .
the incidence of postoperative infections was reported in 5% patients and remains consistent for earlier and later follow ups .
the review of literature suggests that there is uniform consent that the typical patient with a mandibular fracture is male and between 14 and 60 years of age .
the results of this study have revealed that 38% of patients were treated < 24 h , 52% treated between 24 h and 72 h however only 10% treated > 72 h. secondly , the mechanism of trauma is due to violence that is a major cause to sustain a mandibular fracture . in consistent to several studies , which report very high rates of interpersonal violence with almost  epidemic proportions  , all fractures were a consequence of the assault in the patient group . on the other hand , it must be pointed out that none of the cases involved a gunshot wound despite a very high percentage of privately owned small arms .
instinctively , it might cause the postponement for mandible fracture treatment might prompt a higher complication rate . for sure
anderson and alpert showed a 16% general postoperative infection rate in the investigation of 75 mandible fractures ; however , no contaminations happened in patients operated on inside 24 h of trauma .
an alternate study by maloney et al . reported 204 fractures in 131 patients with an in overall infection rate of 4.4% . in any case , consistent patients treated inside 72 h of injury and or trauma had no contaminations and infections .
of all the categories responsible for facial trauma in the present study , violence was the most prevalent , and when compared to the second most frequent category , automobile accidents , this association was statistically significant .
there was a significant increase in the median time to treatment from admission to surgical intervention for patients who treated in maxillofacial operating theatre comparing with those treated in trauma operating theatre .
patients with mandible fracture following road traffic collision ( rct ) or association between alcohol intoxication and assault recorded higher median time to treatment as results of head injuries , chest injury ( rib fractures , hemothorax and pneumothorax ) . despite the fact that in the present study , in all trauma sort classifications there was a prevalence of men , women can likewise be casualties of trauma , particularly interpersonal roughness , on all its structures , and the majority of the times there are large amounts of alcoholic beverages included .
the world health organization reports that violence is dependable for the high health insurance takes and for about 73,000 death / year in europe .
postoperative complications for the mandibular fractures management are fundamentally connected to the severity of the fracture instead of the treatment plan . regarding the relationship of trauma mechanism and fracture site , our study confirms previous findings of a correlation between etiology and fracture pattern .
considering the comparable low number of traffic and occupational related injuries in our study , the safety measurements in these fields seem to have proven their effectiveness in the prevention of facial injuries .
patients conceded from the emergency department for prompt repair were frequently put off because of operating room intervals for absence of employees / work force or more intense cases requiring urgency .
elective repair takes into consideration a brief hospital admission and in addition utilization of surgical facilities , which might be better financially savvy than performing surgery at a tertiary care centers . delay from admission to treatment
the delay from admission to treatment may be because of elective theatre ( maxillofacial theater weekdays 9 am to 5 pm ) .
this investigation has demonstrated that the rate of infection and postoperative complications following surgical treatment of mandible fractures can be eased off by reducing the waiting time from presentation to the emergency and to the operating theatre .
the risk of infection , malocclusion , mal - union and technical complications might rise with treatment delay , and therefore the surgical team must be alert of these consequences when reducing these fractures .
objectives : this study was aimed to assess the impacts of delay treatment of mandibular fracture and its complications . in addition risk variables related such as time to repair , fracture types , substance abuse , causes , surgical management , muddling or complications and duration of clinic stay were also evaluated.materials and methods : the data of patients attending the newcastle general hospital , uk for the management of mandibular fractures were probed . 
 this retrospective clinical trial conducted over 6 months , included 91 patients attending trauma operating theatre during weekdays or weekends . 
 data were analyzed for time to admission and treatment and its relationships to various factors using spss version 20 ( spss inc . , 
 chicago , il).results : time to treatment from the point of admission was 31.50  3.83 h during week days that has been significantly more for patients attending the hospital at weekends or nights . 
 similar trend was observed for total summative time from the incident to treatment analysis.conclusions:this investigation has demonstrated that the rate of infection and postoperative complications following surgical treatment of mandible fractures can be eased off by reducing the waiting time from presentation to the emergency and to the operating theater .
