Abstract
The aim of this study was to determine the pattern of midface trauma with associated concomitant injuries seen in our environment.
This was a prospective analysis of trauma patients with midfacial injuries presenting at a referral center in South West Nigeria. In addition to socio-demographic data, the following information was also obtained: Mechanism of injuries, type of midfacial injuries, concomitant/associated injuries and treatment.
A total of 101 patients with midfacial injuries were involved. They were made up of 85 males and 16 females. The 20-29 year age group was mostly affected (44.6%) and the most common cause of midface injuries was road traffic accident (91.1%). The zygoma was fractured more than any other midfacial bone (46.0%). A total of 144 associated injuries were recorded among these patients, head and ocular injuries accounted for 49 (34%) and 35 (24.3%) respectively. The patients were mostly treated conservatively or by closed reduction.
The rate of head and ocular injuries among patients with midfacial injury was high. Knowledge of these associated injuries provides useful strategies for patient care and prevention of further complications. A multidisciplinary approach is important for optimum management of these patients.

Midfacial injuries were categorized into soft and hard tissue injuries after clinical and radiographic examinations. For each of the 101 patients seen, the following data were collected: Age, gender, mechanism of trauma, type of midfacial injuries and concomitant/associated injuries.

This assertion is further corroborated by the present study in which most of the patients here were men within the 20-29 year age bracket. The main reason among others is the fact that motorbikes are mostly ridden by young men for commercial purpose in our environment and motorbike-related accidents accounted for 45.5% of all the midface injuries in this series. This pattern is in keeping with similar studies both in the developed and the developing world.[<xref rid="ref4" ref-type="bibr">4</xref><xref rid="ref5" ref-type="bibr">5</xref><xref rid="ref6" ref-type="bibr">6</xref><xref rid="ref7" ref-type="bibr">7</xref><xref rid="ref8" ref-type="bibr">8</xref><xref rid="ref9" ref-type="bibr">9</xref><xref rid="ref10" ref-type="bibr">10</xref>]</p><p>The 20-29 years age group from this study was more involved with middle-third facial injuries than any other age group.

This accounted for the injuries in 92 (91.1%) out of the 101 patients seen. The remaining 8.9% was accounted for by other causes such as assaults, falls, sports injuries and industrial accidents. Although this is in consonance with previous Nigerian studies and indeed studies from other developing countries,[<xref rid="ref6" ref-type="bibr">6</xref><xref rid="ref7" ref-type="bibr">7</xref><xref rid="ref8" ref-type="bibr">8</xref><xref rid="ref16" ref-type="bibr">16</xref><xref rid="ref17" ref-type="bibr">17</xref>] it contrasts reports from the developed countries where assaults and interpersonal violence has replaced RTA as the major cause of maxillofacial injuries[<xref rid="ref17" ref-type="bibr">17</xref><xref rid="ref18" ref-type="bibr">18</xref><xref rid="ref19" ref-type="bibr">19</xref><xref rid="ref20" ref-type="bibr">20</xref>] The reason for this is attributable to the poor state of most Nigerian roads, traffic rules are disobeyed and road signs are non-existent. They are often neglected where they exist and most drivers/riders are not properly licensed.[<xref rid="ref7" ref-type="bibr">7</xref><xref rid="ref8" ref-type="bibr">8</xref><xref rid="ref17" ref-type="bibr">17</xref>]</p><p>The prominence of the zygomatic complex as well as its multiple articulations with other bones of the facial skeleton renders it exceptionally vulnerable to fracture when injuries affect the maxillofacial region. This was our finding from the present study in which zygomatic complex fracture accounted for 46% of all the midface fractures, making it the commonest occurring midface fracture as in some other earlier reports.[<xref rid="ref6" ref-type="bibr">6</xref><xref rid="ref21" ref-type="bibr">21</xref><xref rid="ref22" ref-type="bibr">22</xref>]</p><p>Moreover, it has also been documented by Lee <italic>et al</italic>.[<xref rid="ref23" ref-type="bibr">23</xref>] in a study on patterns of facial laceration from blunt injury that as the zygoma would fracture more readily than the frontal bone, the soft-tissue overlying the zygoma would therefore suffer a smaller magnitude of force resulting in contusions rather than open wounds. This could possibly explain the results obtained from the present study in which the soft-tissue overlying the zygoma was more affected by contusions and abrasions instead of lacerations [<xref ref-type="table" rid="T1">Table 1</xref>]. Upper lip on the other hand was the most common site for open wounds or lacerations as has been previously documented.[<xref rid="ref24" ref-type="bibr">24</xref><xref rid="ref25" ref-type="bibr">25</xref>] This is due to the fact that the upper incisors act as sharp objects in cases of injuries to the face, sometimes giving a through and through laceration of the upper lip.</p><p>Maxillofacial injuries in general may occur in isolation or can be associated with other injuries[<xref rid="ref25" ref-type="bibr">25</xref>] and the same is the case for midfacial injuries. Fasola <italic>et al</italic>.[<xref rid="ref6" ref-type="bibr">6</xref>] reported 79.6% of associated injuries in their study population and the authors argued that such a high figure was expected because of RTA being the major etiological factor. Though there is ambiguity about the definition of injuries associated with maxillofacial fractures, the rate of injuries associated with maxillofacial trauma is thought to be quite high,[<xref rid="ref8" ref-type="bibr">8</xref><xref rid="ref26" ref-type="bibr">26</xref><xref rid="ref27" ref-type="bibr">27</xref>] the present study also recorded a rate as high as 83.2% of associated injuries. These associated injuries are reportedly more common when maxillofacial fractures occur from road crashes and high velocity gunshot injuries resulting in multiple organs and systems involvement.[<xref rid="ref6" ref-type="bibr">6</xref><xref rid="ref8" ref-type="bibr">8</xref>] In fact, Haug <italic>et al</italic>.[<xref rid="ref26" ref-type="bibr">26</xref>] was able to show from their series that motorcycle accidents were associated with the most severe head injury. However, this present study concentrated on concomitant injuries associated with midface injuries.</p><p>Neurological injuries were the commonest occurring concomitant injuries in this study accounting for 47.2% followed by ocular injuries with 24.3%, [<xref ref-type="table" rid="T3">Table 3</xref>]. The proximity of the midface to the eyes and the content of the cranium could as well have accounted for this. Hogg <italic>et al</italic>.[<xref rid="ref28" ref-type="bibr">28</xref>] also reported head injuries to have accounted for 87% of the associated injuries in their study in Ontorio, Canada, whereas Obuekwe and Etetafia[<xref rid="ref27" ref-type="bibr">27</xref>] reported 55.8% of head injuries in Benin City, Nigeria. This wide range is probably due to different selection criteria and methods of detecting brain injury. Recognizing concomitant injuries in patients with facial fracture is important for rapid assessment and further management of these patients.</p><p>These results support the use of head computed tomography scan and cervical spine radiographs in most general trauma work-ups, but specifically validates their use in patients with suspected facial fracture.[<xref rid="ref3" ref-type="bibr">3</xref>]</p><p>Despite the obvious advantages of open reduction and rigid internal fixation of facial fractures, it has not become popular in most developing countries (including Nigeria) mainly because of the cost.[<xref rid="ref8" ref-type="bibr">8</xref>] Only four patients representing 5.6% had open reduction and internal fixation with trans-osseous wires while the rest had closed reductions [<xref ref-type="table" rid="T4">Table 4</xref>]. Nevertheless, previous Nigerian reports have attested to the satisfactory results obtained using simple methods of closed reduction and mandibulo-maxillary fixation.[<xref rid="ref4" ref-type="bibr">4</xref><xref rid="ref6" ref-type="bibr">6</xref>]</p><table-wrap id="T4" position="float"><label>Table 4</label><caption><p>Treatment modalities for midfacial injuries</p></caption><graphic xlink:href="NJS-20-26-g006"></graphic></table-wrap></sec><sec sec-type="conclusion" id="sec1-5"><title>C<sc>ONCLUSION</sc></title><p>Our study found that cerebral and orbital injuries are often associated with midfacial fractures. Knowledge of injuries associated with maxillofacial fractures and coordination of trauma teams, is vital for the early stabilization and treatment of these patients. Irrespective of the severity of injury, patients who sustained maxillofacial injury were more likely to be discharged earlier than those with concomitant injuries. The presence of moderate to severe head injury, chest injury and orthopedic injury significantly prolong hospital stay. The usage of protective elements by road users especially motorcycle riders and their passengers should be enforced to reduce the rate of head injury and indeed other associated injuries among trauma patients in general.</p></sec></body><back><fn-group><fn fn-type="supported-by"><p><bold>Source of Support:</bold> Nil.</p></fn><fn fn-type="conflict"><p><bold>Conflict of Interest:</bold> None declared.</p></fn></fn-group><ref-list><title>R<sc>EFERENCES</sc></title><ref id="ref1"><label>1</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Paludetti</surname><given-names>G</given-names></name><name><surname>Almadori</surname><given-names>G</given-names></name><name><surname>Corina</surname><given-names>L</given-names></name><name><surname>Parrilla</surname><given-names>C</given-names></name><name><surname>Rigante</surname><given-names>M</given-names></name><name><surname>Ottaviani</surname><given-names>F</given-names></name></person-group><article-title>Midfacial fractures: Our experience</article-title><source>Acta Otorhinolaryngol Ital</source><year>2003</year><volume>23</volume><fpage>265</fpage><lpage>73</lpage><pub-id pub-id-type="pmid">15046415</pub-id></element-citation></ref><ref id="ref2"><label>2</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Roy</surname><given-names>SK</given-names></name><name><surname>Suresh</surname><given-names>PM</given-names></name></person-group><article-title>Etiology and management of zygomaticomaxillary complex fractures in the armed forces</article-title><source>Med J Armed Forces India</source><year>2005</year><volume>61</volume><fpage>238</fpage><lpage>40</lpage></element-citation></ref><ref id="ref3"><label>3</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Alvi</surname><given-names>A</given-names></name><name><surname>Doherty</surname><given-names>T</given-names></name><name><surname>Lewen</surname><given-names>G</given-names></name></person-group><article-title>Facial fractures and concomitant injuries in trauma patients</article-title><source>Laryngoscope</source><year>2003</year><volume>113</volume><fpage>102</fpage><lpage>6</lpage><pub-id pub-id-type="pmid">12514391</pub-id></element-citation></ref><ref id="ref4"><label>4</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Ugboko</surname><given-names>VI</given-names></name><name><surname>Odusanya</surname><given-names>SA</given-names></name><name><surname>Fagade</surname><given-names>OO</given-names></name></person-group><article-title>Maxillofacial fractures in a semi-urban Nigerian teaching hospital.
