Abstract

Background: Numerous methods have been described for achievement of Intermaxillary fixation in the treatment offractures of facial skeleton. Conventional methods like Erich arch bars and eyelet wires are currently the most commonmethods for achieving intermaxillary fixation (IMF), however, they have their own disadvantages. Since 1989, IMF usingintraoral self-tapping IMF screws has been introduced for treatment of mandibular fractures. The aim of this study wasto evaluate the efficacy, advantages, disadvantages and potential complications associated with using of selftappingIMF screws in the treatment of mandibular fractures.Material and Methods: Twenty patients with favorable mandibular fractures, attended to Oral and Maxillofacial Surgeryunit, AL-yarmuk Teaching Hospital between November 2014 and October 2015, they were treated with IMF screws. Theparameters considered were duration of the procedure, perforations in the gloves, patient acceptance, oral hygiene,iatrogenic dental injuries, mouth opening, healing outcome, occlusal discrepancy and needle stick injuries during IMF.Results: The patients included in this study were 20 (17 males and 3 females). The extremes of age in this study rangedfrom 12 to 37 years. Three patients had 2 fracture lines. Assault was the most common cause of fractures. The mostcommon site of fracture was the body and parasymphysis regions. Two screws (2.5%) from 80 screws becameloosened. One patient (5%) ended with malunion and malocclusion. One patient (5%) developed infection at screwsite. Three patients (15%) developed screws soft tissue burying.Conclusion: IMF screws considered to be a useful modality of treatment to establish maxillomandibular fixation. It issafe, and time-sparing technique; however, it is not without limitations or potential consequences in which the surgeonmust be aware of in order to provide safe and effective treatment

Abstract

Background and Objectives: A retrospective study was done to report the incidence of mandibular fractures in children up to fifteen years of age seen in Rizgaree teaching hospital /Erbil / Kurdistan region of Iraq.Methods: The patient's records of 62 injured child aged 0-15 years, from 1/1/ 2002 to 31/12/2008 were retrieved and relevant data was recorded and analysed. A data collection sheet was designed to record patient's name, sex, age, site of fracture, the etiology of the injury and the method of treatment and complications.Results: The total number of patients who presented with mandibular fracture in children was 62 (78.5%). The ratio of boys to girls was 43 (69.4%) boys and 19 (30.6%) girls (2.2:1). Most of the trauma reported in age group 12-15years (46.8%). Regarding the site of fracture, condylar fracture (46.7%) was most common followed by symphesis (27.4%), dentoalveolar (14.5%), angle (8.1%) and body (3.3%). The main etiology of fracture was fall from height (54.8%). Most of the patients were treated by closed reduction (88.7%) and fixation.Conclusions: The incidence and etiology of mandibular fracture in children differs among different populations. In our study, the incidence was not very common, fall was most common cause, condylar fracture was most common. Most of the cases can be treated conventionally.

Abstract

Aims: The aims of the study are to find the incidences, types, sides and sites of mandibular fracture accompanied with head injuries in Ninavah Governorate. Materials and Methods: Data of trauma cases were collected from general, local, private hospitals and health sectors in Ninavah Governorate with a head injury and mandibular fracture for one year duration from June 2006 to May 2007. Age, etiology, types, hospitals, sides and sites, distribution were arranged in tables, chi square and P value used for statistic analysis. Results: The total number of head injury cases was (5828). The total num-ber of fractures mandible with and without head injury was (282) cases means (4.84%) of total number of head injury cases, while mandibular fracture with head injury cases incidence was (76) cases (1.3%) of total number of head injury cases . Conclusions: Children were the most common age group affect-ed by head injury, while geriatric age group was the least. Male showed high percentage than female in a ratio about 2:1. Low incidence of association between head injury and fracture mandible which means that there is no need for delaying maxillofacial treatment. Falls from height and bullet injuries were the common cause of head injury and fracture mandible (dentoalveolar fractures showed high incidence followed by body fractures).

Abstract

Background:Open reduction and internal fixation (ORIF) of using miniplates and screws is the treatment of choice ofmandibular fractures. It is important to know both: the region where the bone provides a firm anchorage, and thetopography of the dental apices and inferior alveolar nerve to avoided imaging them when inserting the screw. Theaim of this study is to determine the thickness of buccal cortical plate and that of buccal bone at the parasymphysisand mandibular body, thereby determining the area that provide a firm anchorage and the maximum length ofmono-cortical screws that can be safely placed in these regions without injuring the tooth roots or mandibular nerve.Materials and Methods: The sample of the present study was 110 Iraqi subjects (77 males & 33 females) aged (18-35)years old who admitted to Computed Tomography scan unit in AL-Sadr Teaching Hospital in Al-Najaf city to getComputed Tomographic examination of facial bones. The conventional sections of CT (axial, coronal) used to dothe measurements and dental planning analysis also used. The thickness of buccal cortical plate and the thickness ofbuccal bone were measured at the level of root apex of (canine, first premolar, second premolar) and at the levelofroot apex and inferior alveolar canal in mesial and distal root of first and second molar.Results: There was no statistical significant difference in buccal cortical plate and buccal bone thickness betweenage and gender at most measured sites. Using of 4mm screw is safe in distal root region of 2nd molar at the level ofapex and that of inferior alveolar canal for both males and females. Moving slightly forward in position to the mesialroot of 2nd molar 1mm will be lost from safety margin, while making only the 3mm screw is safe. For the remaininganterior positions only the minimum screw length of 2 mm is safe.Conclusions: Thickness of buccal cortical plate and buccal bone in various sites could be measured precisely usingMultislice Computed tomography which can guide surgeons in selecting the proper screw length without causinginjury to tooth apex or inferior alveolar nerve.

Abstract

Background: The treatment of mandibular fractures (#s) had traditionally involved re-establishment of occlusion by Intermaxillary Fixation (IMF). In order to eliminate the morbidity associated with IMF. IMF has associated morbidity such as weight loss, interference with oral hygiene measures and patient discomfort. Increasingly over the three past decades, oral and maxillofacial surgeons have developed techniques of treating mandibular fractures using internal fixation. The routine use of miniplats in oral and maxillofacial surgery has gained popularity since Champy reporded modification of the original technique of Michelet.Objective: Evaluation of titanium miniplate osteosynthesis in treatment of mandibular fractures and comparison of the out come, advantages, disadvantages and complications between intra oral and extra oral approach for the application of titanium miniplates. Methods: This study was performed prospectively on 24 patients with 28 isolated mandibular fractures and treated by open reduction and titanium miniplate osteosynthesis. Ten patients had intra oral approach and fourteen patients had extra oral approach.Result: The overall complication rate was 25%. In the group, in which extra oral approach was used, the complication rate was 21.4% (3patients): 2 patients with facial scarring and 1 patient with malocclusion. In the group, in which intra oral approach was used, the complication rate was 30% (3 patients): 1 patient with paraesthesia of the lip, 1 patient with postoperative infection and 1 patient with root injury.Conclusion: Miniplate osteosynthesis gives acceptable result, and it can be recommended as a routine method for treatment of all mandibular #s. Intra oral approach is advantageous to, and gives comparable results with extra oral approach. Experience in the technique is an important factor in the outcome. Key words: Trauma-Mandibular fracture-Miniplate osteosynthesis
