the aim of this study was to evaluate the incidence and etiology of maxillofacial fractures and also to evaluate different treatment modalities .
the sample consisted of 1,038 patients , with maxillofacial injuries treated at our center from june 2006 to june 2011 .
cause , type , site of injury , gender , age and treatment given to them , all these parameter are evaluated .
the results of this study exhibit that road traffic accidents is the main reason for maxilla facial injuries followed by fall from height .
the miniplate osteosynthesis was the most widespread of the fixation technique but conservative management of the fractured bone also has a significance importance in treatment modalities .
hippocrates described an array of facial injuries as long ago as 400 bc . the injuries to the facial regions are clinically highly significant for number of reasons .
maxillofacial region is associated with a number of important functions of the daily life sight , smell , eating , breathing , and talking .
the number of maxillofacial injuries is continuously increasing due to rise in traffic , and failure to take preventive measures in the traffic leads to road traffic accidents , which is the main etiological factor in maxillofacial fractures .
the aim of this study was to find out the incidence and pattern of maxillofacial injuries resulting from various etiological factors and treatment modalities and their complications .
the maxillofacial injuries remain serious clinical problems because of its anatomical significance , i.e. , important organs are located in this area and digestive and respiratory systems start from this area . due to anatomical proximity together with maxillofacial injuries ,
the damage to the central nervous system may occur and injuries in this region can result in serious dysfunction .
this descriptive analytical study assesses the etiology , type , demographic , and treatment data of maxillofacial fractures managed at our center in the last 5 years .
the sample consisted of 1,038 patients , with maxillofacial injuries treated at our center from june 2006 to june 2011 .
around 350 patients who were not admitted in the department and were treated as the outdoor patients were not included in this study , as it was not possible to obtain their complete data .
the diagnosis was made on the basis of history , clinical examinations , and other investigations .
radiographs , orthopantomogram , occipitomental view , submentovertex view , posterio - anterior ( p.a . )
view mandible , lateral oblique view mandible , were the main tools to confirm clinical diagnosis .
the parameters assessed included age , sex , etiology , fractured bones , and treatment modalities and complications .
different approaches for reduction and fixation of fractures were used according to indications either intra - oral approach or extra - oral approach .
the most common site of fracture maxilla was found to be leforte 2 fracture . in our study ,
gender distribution was 9:1 [ table 1 ] , but in other studies , it was 2:1 .
males are more prone for trauma because of outdoor works , rash driving , and alcoholism .
the most common involved age group was 21 - 30 ( 37.66% ) years [ table 2 ] , followed by 31 - 40 years ( 19.36% ) .
the road traffic accident ( 97.10% ) was the most common etiological factor [ table 3 ] .
most of the patients had multiple bone fractures including mandible , maxilla , and zygomatic complex fracture ( 62.42% ) [ table 4 ] .
adeyemo stated that road traffic crashes remain the major cause of maxillofacial injuries , unlike in most developed countries where assaults / interpersonal violence has replaced road traffic crashes as the major cause of the injuries .
fracture involving different bones ( n=1,038 ) the most commonly involved site was body of the mandible ( 51.50% ) followed by parasymphysis ( 45.25% ) .
coronoid fracture was reported to be least common ( 1.08% ) [ table 5 ] . among maxillary fractures ,
the most common fracture was leforte 2 fracture ( 84.00% ) followed by leforte 1 and then leforte 3 [ table 6 ] .
, they found there were ( 72.9% ) mandibular , ( 13.9% ) maxillary , ( 13.5% ) zygomatic , ( 24.0% ) zygomatico - orbital , ( 2.1% ) cranial , ( 2.1% ) nasal , and ( 1.6% ) frontal injuries .
car accidents ( 30.8% ) , motorcycle accidents ( 23.2% ) , altercations ( 9.7% ) , sports ( 6.3% ) , and warfare ( 9.7% ) caused the maxillofacial injuries .
regarding distribution of mandibular fractures , 32% were seen in the condylar region , 29.3% in the symphyseal  parasymphyseal regions , 20% in the angle region , 12.5% in the body , 3.1% in the ramus , 1.9% in the dentoalveolar , and 1.2% in the coronoid region .
the distribution of maxillary fractures was le fort ii ( 54.6% ) , le fort i ( 24.2% ) , le fort iii ( 12.1% ) , and alveolar ( 9.1% ) .
of the all mandibular fractures , 56.9% were treated by closed reduction , 39.8% by open reduction , and 3.5% by observation only . of all maxillary fractures ,
54.6% were treated using closed reduction , 40.9% using open reduction , and 4.5% with observation only .
approximately , 52.1% of the patients were treated under general anesthesia and 47.9% were treated under local anesthesia and sedation . regarding treatment modalities we used ,
most of the patients were treated by open reduction and fixation ( 72.83% ) and conservative management ( 22.73% ) , and 2.50% patients were treated by circum - mandibular wiring mostly in pediatric patients and edentulous patients [ table 7 ] . according to ajmal , et al .
, open reduction and internal fixation has proven to be the most effective method for treatment of mandibular fractures . in
most of the patients , open reduction & internal fixation ( orif ) was done under general anesthesia , rest of them under local anesthesia and conscious sedation .
all the patients of circum - mandibular wiring were treated under general anaesthesia ( ga ) .
the close reduction was done under local anesthesia . according to study of back , et al . , most patients were males ( 76% ) , the average age was 38 years , and drugs or alcohol were a significant aspect of the history in 30% of the cases .
the most common mechanism of injury was assault ( 47% ) , followed by falls and sporting injuries .
fifty percent of the fractures involved the orbital or orbito - zygomatic complex , and 55% had associated injuries .
average follow - up was for 6 weeks ( range : 0 - 44 weeks ) .
most patients were managed conservatively based on our current criteria of un - displaced / minimally displaced fracture ( 57% ) or minimal / no symptoms ( 24% ) . at final review ,
the other reasons for conservative management included patient non - compliance ( 11% ) and medical contraindications ( 8% ) .
being a developing country , the socioeconomic status of the majority is low and the patients coming to our center are from remote areas of the state and from neighboring states with the poor background , so choice of plating systems are limited .
miniplates ( stainless steel or titanium ) , 3d plates , locking plates , reconstruction plates , lag screws , and biodegradable systems were used .
reconstruction of orbital floor was done with autogenous bone graft and in few cases with medpore . in most of the patients ,
pre - operative photograph of patient pre - operative photograph of patient pre - operative ct scan pre - operative ct scan intra - operative photograph of patient intra - operative photograph of patient post - operative ct scan post - operative ct scan post - operative photograph of patient in patients with only mandibular fractures ( 497 ) , 21% patients were treated with intermaxillary fixation and 84.78% with open reduction and fixation with different systems [ table 8 ] .
treatment modalities used for mandible fractures ( n=497 ) danda , et al . concluded from their study that the results of this study have shown that no significant clinical difference exists between patients undergoing closed treatment and rigid maxillomandibular fixation or open reduction and internal fixation .
however , a radiographically better anatomic reduction of the condylar process was seen in the patients treated with open reduction and internal fixation . out of patients who received orif ( 64.78% )
, in 25.19% cases plates were removed within 6 months to 2 years because of secondary infection , sinus formation , or pus discharge from the site .
there was no single case of delayed union or non - union reported [ tables 6 and 9 ] .
world health organization has estimated that nearly 25% of all injuries fatalities worldwide are a result of road traffic crashes with 90% of the fatalities occurring in low- and middle - income countries .
road traffic accidents have been steadily falling in the developed countries ; they continue to rise with the horrifying speed in the low- and middle - income countries of africa and asia .
fatigue is another important factor especially in commercial vehicle drivers who drives very long distances .
bad road conditions also play an important role in rta but some studies reported more rtas on well paved and broad roads .
the reason for the accidents in our country is due to violation of traffic rules , whereas in developed countries , accidents are most commonly due to alcoholic intoxications .
this study shows that the most common cause of facial injuries was road traffic accidents , which is consistent with observation in other studies in india and other countries .
mandible fracture was the most common fracture observed in this study because it is the most prominent bone in the face and is often fractured more than strongly supported middle third of face .
fractures have been treated by a series of methods including close reductions , internal fixation , and circum - mandibular wiring .
coletti stated that the imf self - drilling / tapping screws has been shown to be a useful modality to establish maxillomandibular fixation .
it is a safe and time - sparing technique ; however , it is not without limitations or potential consequences which the surgeon must be aware of in order to provide safe and effective treatment .
pediatric patients were treated by circum - mandibular wiring and few cases with bioresorbable plates under general anesthesia .
pediatric patients benefit from the advantage of bioresorbable plates as it results in faster mobilization and the avoidance of secondary surgery for removal of implants .
the old age successful management of these injuries using close reduction technique should be considered .
patients with edentulous atrophic mandible were all so treated with circum - mandibular wiring and results were satisfactory .
the minimally displaced fractures can be treated with conservative methods like close reduction to avoid hospitalization , cost factor , and significantly low risk of infections . in our study , there was no infection , non - union , mal union , or any functional disability reported in the patients who received inter maxillary fixation for 4 - 6 weeks .
temporomandibular joint stiffness was reported during first week of after releasing imf which comes normal after a week with physiotherapy .
however despite the professional and commercial interest in open reduction and semi - rigid fixation , we should think about patient 's interest affordability and well - being .
sometimes , patients general condition , neurosurgical conditions , spinal injuries , medically compromised patients should be treated with conservative treatment .
it is very cost effective , reduces hospital stay , or even no need for hospitalization .
only dietary restrictions due to mouth closure and patient compliance are limitations . in few patients like
epileptic , we can not use inter maxillary fixation for the management of maxillofacial trauma in minimally displaced fractures .
other studies also did not show a clear overall benefits of the open reduction and fixation over conventional maxillo mandibular fixation ( mmf ) treatment .
marker , etal . found non - surgical treatment of fracture of condoyle is non - traumatic , safe , and predictable and also support the conservative management of mandibular fractures .
the cases with extensive displacement , associated fractures of mid - face , open reduction and fixation are indicated . according to worsaae and thorn in the study of open versus closed reduction of unilaterally dislocated low subcondylar fractures
, they concluded that complications such as malocclusion , mandibular asymmetry , impaired masticatory function , and pain located to the affected joint or masticatory muscles were seen significantly more frequent in patients treated with closed reduction compared with those treated surgically ( p = 0.005 ) .
neither the degree of dislocation of the proximal fragment , concomitant mandibular fractures nor the absence of posterior occlusal support seemed to influence the results .
the results of this study exhibit that road traffic accidents is the main reason for maxilla facial injuries followed by fall from height .
the miniplate osteosynthesis was the most widespread of the fixation technique but conservative management of the fractured bone also has a significance importance in treatment modalities .
