Management of Mandibular Body Fracture in an Eighteen-Month Old Child - A Case Report

@#With the advancement of the transportation system and improvement in road conditions, the number of high-velocity accidents has also increased. Almost all of these reported cases involve individuals who had travelled in vehicles without adhering to personal protection standards and with rash driving. Injuries to the facial region can be profoundly disturbing and particularly in children. Parents find it very distressing to see their child in pain with a disfigured or injured face. It is difficult to manage such crying & sometimes uncontrollable children. The most commonlyinjuredfacialbonesareNasal,Zygomaticandthe Mandible. The incidence of facial bone fracture in children is uncommon, and we present a case report of an18-month old child with a history of road traffic accident and swelling on the right side of the face. Intraoral examination shows limited mouth opening with submucosal ecchymosis in the right buccal mucosa and based on clinical and computed tomographic scan working diagnosis of fracture in the right body of the mandible was arrived. The child was treated with the circum-mandibular wiring to stabilize the mandibular fracture under general anaesthesia. After three weeks the splint was removed. The injury healed without complications in the post-operativeperiod.

Versatile midfacial degloving approach in oral and maxillofacial surgery

OBJECTIVES: Oral and maxillofacial surgeons must gain mastery of various approaches to the midface due to the increasing incidence, complexity, and severity of presenting midfacial fractures. Unlike in the case of other body parts, the need to preserve facial aesthetics makes it more difficult for the surgeon to select an approach for managing the facial injuries. The midfacial degloving (MFD) approach is a combination of intraoral and intranasal incisions made to access the midface without any external incision. The aim of the present study was to evaluate the efficacy of MFD in maxillofacial surgery and to assess its advantages and complications. MATERIALS AND METHODS: The MFD approach was used in five cases, with three cases treated with open reduction and internal fixation and two cases operated on for posttraumatic deformity. Nasal dorsum augmentation was completed in three cases and nasal osteotomy was performed in one case. The bicoronal flap technique was combined with MFD for frontal bone augmentation in one case. The intraoperative time required for flap completion and the ease of performing the planned procedures were noted. Postoperative evaluation was done for reduction, aesthetics, function, and complications. RESULTS: Access was excellent for performing all planned procedures. Average time spent for flap elevation and exposure of the midface was 63 minutes. Complications like postoperative swelling, infraorbital nerve paresthesia, and intranasal crusting were all transient. No long-term complications like stenosis of the nose, sneer deformity, or weakness of the facial muscles were noticed. Additionally, no complications were noted when MFD was combined with bicoronal flap. CONCLUSION: Though the MFD approach is technically demanding and takes more time than other facial approaches, it should be learned and applied by maxillofacial surgeons in selective cases, as it provides complete exposure of the midface without facial scarring.

Introduction: The maxillofacial region is vulnerable to injuries. In Cuba, few studies related to urgent care services have been carried out in maxillofacial traumatology, which led to an increase of motivation to conduct this research. Objective: To characterize maxillofacial trauma from a clinical and epidemiological point of view in patients treated in General Calixto García Hospital from June 2016 to June 2017. Material and Methods: A descriptive cross-sectional study was conducted with the universe of patients (2412 ones) that were treated in the Emergency Service of General Calixto García University Hospital with the diagnosis of maxillofacial trauma from June 2016 to June 2017. The variables used were: age groups, sex, etiological factor, type of injury, and therapeutic behavior. Results: In the study, the patients aged between 19 and 30 years represented 41.0 percent; the male sex 69.0 percent; and the traffic accidents 34.6 percent. The most frequent hard tissue injuries were nasal fractures (13.9 percent); and the soft tissue injuries were purely integumentary wounds (82.1 percent). Bandage placement was used in 89.1 percent, and wound suture in 84.1 percent. Conclusions: The behavior of the maxillofacial trauma in the Emergency Service of General Calixto García University Hospital, showed that it predominates in men of middle age due to traffic accidents. Soft tissue injuries were the predominant type of injuries, among them, the purely integumentary wounds. The conservative behavior in its modality of bandage placement was the most commonly used(AU)

Zygomatic arch fracture in a dog treated with Veterinary Cuttable Plate - case report / Fratura de arco zigomático em um cão tratado com placa veterinária cortável - relato de caso

The purpose of this paper is to describe a case of a right zygomatic arch fracture in a 5-year-old male Labrador Retriever diagnosed with aid of 3D Computed Tomography reconstruction. Because of the depressed fracture and interference with the eyeball, surgical repair of the right zygomatic arch fracture was performed with open reduction and stabilization with an 11-hole, 2.7mm Veterinary Cuttable Plate. Radiographs taken 60 days after surgery revealed that fracture healing occurred without complications with improved function and cosmetic appearance. Ninety days after surgery the patient was clinically discharged.(AU)

O objetivo deste trabalho é descrever um caso de fratura do arco zigomático direito em um Labrador Retriever, macho, de cinco anos de idade, diagnosticado com reconstrução 3D de tomografia computadorizada.

As radiografias realizadas 60 dias após a cirurgia revelaram que a consolidação óssea ocorreu sem complicações, com melhor funcionalidade e aparência estética. Noventa dias após a cirurgia, o paciente teve alta clínica.(AU)

Relationship between Locations of Facial Injury and the Use of Bicycle Helmets: A Systematic Review

The aim of this study is to review the protective effect of a bicycle helmet on each facial location systematically. PubMed was searched for articles published before December 12, 2014. The data were summarized, and the odds ratio (OR) between the locations of facial injury was calculated. A statistical analysis was performed with Review Manager (The Nordic Cochrane Centre). Bicycle helmets protect the upper and middle face from serious facial injury but do not protect the lower face. Non-wearers had significantly increased risks of upper facial injury (OR, 2.07; P<0.001) and of middle facial injury (OR, 1.97; P<0.001) as compared to helmet users. In the case of lower facial injury, however, only a slightly increased risk (OR, 1.42; 95% confidence interval (CI), 0.67-3.00, P=0.36) was observed. The abovementioned results can be attributed to the fact that a helmet covers the head and forehead but cannot cover the lower face. However, helmets having a chin cap might decrease the risk of lower facial injury.

Maxillofacial Trauma Trends at a Tertiary Care Hospital: A Retrospective Study / 대한악안면성형재건외과학회지

PURPOSE: Maxillofacial fractures are rapidly increasing from car accidents, industrial accidents, teenaged criminal activity, and sports injuries. Accurate assessment, appropriate diagnosis, and preparing individual treatment plans are necessary to reduce surgical complications. We investigated recent trends of facial bone fracture by period, cause, and type, with the objective of reducing surgical complications. METHODS: To investigate time trends of maxillofacial fractures, we reviewed medical records from 2,196 patients with maxillofacial fractures in 1981~1987 (Group A), 1995~1999 (Group B), and 2008~2012 (Group C). We analyzed each group, comparing the number of patients, sex ratio, age, fracture site, and etiology. RESULTS: The number of patients in each period was 418, 516, and 1,262 in Groups A to C. Of note is the increase in the number of patients from Group A to C. The sex ratios were 5.6:1, 3.5:1, and 3.8:1 in Groups A, B, and C. The most affected age group for fracture is 20~29 in all three groups. Traffic accidents are the most common cause in Groups A and B, while there were somewhat different causes of fracture in Group C. Sports-induced facial trauma was twice as high in Group C compared with Group A and B. Mandible fracture accounts for a large portion of facial bone fractures overall. CONCLUSION: We observed an increase in facial bone fracture patients at Kyungpook National University Dental Hospital over the years. Although facial injury caused by traffic accidents was still a major cause of facial bone fracture in all periods, the percentage decreased. In recent years, isolated mandible fracture increased but mandible and mid-facial complex fracture decreased, possibly because of a reduction in traffic accidents.

Management of a Gunshot Wound at the Temporal Region: Case Report

A Case of Post-Traumatic Olfactory Disorder Presenting Negative Results of Schneider Test due to Trigeminal Nerve Injury / 대한이비인후과학회지

There has been a considerable increase in the number of patients with olfactory disorder due to head and facial injuries. Conventional olfactory function evaluation methods, such as T&T olfactometer, the Schneider test and the Alinamin test have been widely used in clinical practice. Among these, the Schneider test can determine whether the patient is a malingerer. A woman who sustained head and facial injuries visited our department with the chief complaint of anosmia. The patient underwent conventional olfactory function tests, including T&T olfactometer and the Schneider test. T&T olfactometer revealed olfactory loss, but the Schneider test did not. Thus, she was diagnosed with malingering. However, her diagnosis of olfactory disorder and concurrent trigeminal nerve injury was made definite during the follow-up period. We herein report a 30-year-old female patient with olfactory disorder who was misdiagnosed with olfactory malingering based on the negative result of the Schneider test. A brief review of the literature has been included.

Maxillofacial injuries in a group of Brazilian subjects under 18 years of age

OBJECTIVE: The purpose of this study was to perform a clinical retrospective analysis of the etiology, incidence and treatment of selected oral and maxillofacial injuries in Brazilian children and adolescents. MATERIAL AND METHODS: This study was conducted during a 14-year period between 1986 and 2000. All patients were admitted to Hospital XV in the city of Curitiba, State of Paraná. Age, gender, monthly distribution, etiology, soft injuries, associated injuries, site of fractures and methods of treatment were reviewed. RESULTS: Of the total of 350 patients of all ages treated for facial injuries, 29.42% were within the age range of the study (0 to 18 years). Mean age was 10.61. Of the patients, 63.1% were male. The most common cause of injury was accidental falls (37.87%), followed by bicycle and motorcycle accidents (21.36%). Of the 103 patients, 88.34% had single injuries. Mandibular fractures were the most common and the condylar region was particularly affected. CONCLUSIONS: Facial trauma is a relatively common occurrence in children. The study indicates that fractures in children and adolescents differ quite considerably from an adult population.

Wooden Foreign Body in the Parotid Gland

PURPOSE: Now the CT scanner and PACS program proved to be an excellent instrument for detection and localization of most facial foreign bodies above certain minimum levels of detectability. The severity of injury in penetrating trauma on the face is often underestimated in physical examination. Wood, with its porous consistency and organic nature, provides a good medium for microbial agents. This is a report of our recent experience with wooden foreign bodies in the parotid gland imaged with CT. METHODS: A 9-year-old boy was referred for evaluation of possible retained foreign body within his face. One day earlier, he had fallen, face down approximately 1 miter onto ground. He had subsequently undergone an exploration of his right parotido-masseteric area at an outside hospital with repair of a right facial laceration. Enhanced 2 mm axial and coronal CT scans were obtained through the face. Axial and coronal CT images were obtained with a General Electric(Milwaukee, Wis) 9800 CT scanner at 130kV, 90mA, with a 2mm section thickness. RESULTS: We finally decided the linear "gas" attenuation was a foreign body because of its linear configuration, which did not conform to that of an anatomic structure, and on the basis of articles that described a wood foreign body in the orbit as having the appearance of air. We found that wood was hypoattenuating(-464+/-27HU). CONCLUSION: We recommend this type of software program for CT scanning for any patient with an injury on the face in which a foreign body is suspected.

A case of multiple facial gunshot wounds

Gunshot injuries can range from the most minor to the life-threatening. Multidisciplinary care is required for successful management of patients, In the acute phase, care may involve emergency surgeons, anaesthesists, neurosurgeons, ophthalmic surgeons, vascular surgeons, ENT specialist in addition to the oral and maxillofacial surgeons. Afterwards, definitive treatment of facial gunshot injuries depends ultimately on the abilities and skills of the oral and maxillofacial surgeons, and their appreciation of such injuries. The timing and sequence of the surgical procedures used for reconstruction and rehabilitation of maxillofacial gunshot injuries are crucial to a successful outcome and aesthetic result. If incorrect, they may lead indefinitely to infection, graft rejection, wound dehiscence with consequent multiple revisional operations and complication which will prolong hospital stay and increase treatment costs and morbidity on those patients. We present a gunshot case of a 46-year-old man who tried to commit sucide, and have avulsive and penerating wounds on the face and the neck. We removed the scattered bullets and fragments successfully and the wounds were closed primarily.

A Clinical Survey on Anesthetic Management in Patients with Maxillo - Facial Trauma / 대한마취과학회지

A clinical analysis of 249 patients with maxillo-facial trauma, who underwent general anes- thesia from January 1992 to December 1993 at Lee-Rha General Hospital, were made in order to investigate various case characteristics such as sex ratio, age distribution, types of trauma, fracture sites, associated injuries, underlying medical problems, abnormal laboratory findings, intubation, and preoperative physical condition. It was found that males outnumbered females showing the peak age incidence in 20's and 30's. The high velocity motor vehicle accidents was the most common cause of trauma and the mandible was the most frequent fracture sites. Among 96 associated injury cases, 63 cases were neumsurgical problems. Underlying medical problems or abnormal laboratory findings were present in 28.9% of the patients studied and preoperative physical status 1 or 1E (ASA classification) was most common accounting for 54.8% of the patients studied. Of the patients who received endotracheal intubation, 73.5% were done via a nasotracheal route.
