Maxillofacial trauma in the elderly

PURPOSE This article gives a general description of the incidence, causes, and complexity of maxillofacial fractures in the elderly and discusses whether modification is required in assessment, surgical indications, and techniques in such cases. PATIENTS AND METHODS A retrospective clinical and radiologic study evaluated 222 patients older than 60 years of age (mean age, 70.3) hospitalized with maxillofacial trauma over the period 1987 to 1996 in the Division of Maxillofacial Surgery, University of Turin. The patients were classified according to the following parameters: age, cause of injury, site of trauma, presence of associated fractures, pertinent medical history, type of treatment, length of hospitalization, and complications. The data were compared with those from a control group consisting of 178 adult patients younger than 60 years of age. RESULTS The presence of a preexisting systemic pathologic condition was the most important factor in determining hospitalization time, which was greater than in the control group. In 89 patients (40.1%), no treatment was considered necessary, whereas 133 patients (59.9%) were treated by surgery. In 115 patients (86.5%), the fractures were treated by open reduction and internal fixation, whereas closed reduction was used in 18 patients (13.5%). There were complications with six patients (2.7%), and one died in the hospital. CONCLUSIONS The findings of this study suggest that surgical intervention is less frequently indicated in facial trauma of the elderly because of physiologic, psychologic, and social changes brought on by the aging process. The principles of treatment, the results, and the complications do not differ greatly in this group when compared with the normal adult population.

European Maxillofacial Trauma (EURMAT) project: A multicentre and prospective study

The purpose of this study was to analyse the demographics, causes and characteristics of maxillofacial fractures managed at several European departments of oral and maxillofacial surgery over one year. The following data were recorded: gender, age, aetiology, site of facial fractures, facial injury severity score, timing of intervention, length of hospital stay. Data for a total of 3396 patients (2655 males and 741 females) with 4155 fractures were recorded. The mean age differed from country to country, ranging between 29.9 and 43.9 years. Overall, the most frequent cause of injury was assault, which accounted for the injuries of 1309 patients; assaults and falls alternated as the most important aetiological factor in the various centres. The most frequently observed fracture involved the mandible with 1743 fractures, followed by orbital-zygomatic-maxillary (OZM) fractures. Condylar fractures were the most commonly observed mandibular fracture. The results of the EURMAT collaboration confirm the changing trend in maxillofacial trauma epidemiology in Europe, with trauma cases caused by assaults and falls now outnumbering those due to road traffic accidents. The progressive ageing of the European population, in addition to strict road and work legislation may have been responsible for this change. Men are still the most frequent victims of maxillofacial injuries.

Surgical Management of Orbital Trapdoor Fracture in a Pediatric Population

PURPOSE Orbital trapdoor fractures are pure orbital floor fractures with herniation and entrapment of the orbital contents, leading to restricted eye movement and diplopia. Trapdoor fractures in children have been discussed widely in published reports; however, the treatment policy and outcome remain controversial, although early treatment has been advocated. Our retrospective study analyzed the long-term results of pediatric patients undergoing surgery for trapdoor fractures to determine the outcome in relation to the type of fracture and the timing and technique of intervention. PATIENTS AND METHODS The present study included 24 patients (age range 6 to 16 years) who underwent surgery for trapdoor fractures from 1998 to 2007. The demographic, etiologic, radiologic, and surgical findings, interval between trauma and surgery, surgical techniques, and complications were recorded. Diplopia, ocular motility, dysesthesia, and scar quality were recorded at follow-up. RESULTS The follow-up duration averaged 36 months. At follow-up, 1 (8.3%) of 12 patients who underwent surgery within 24 hours (urgent treatment) had residual diplopia. In contrast, 3 (37.5%) of 8 patients who underwent surgery 24 to 96 hours (early treatment) and 4 (100%) of 4 who underwent surgery after 96 hours (late treatment) had diplopia. No sensory deficit of the skin or unesthetic eyelid scar was noted. CONCLUSIONS We found a correlation between the outcome and the timing of surgery for trapdoor fractures in the pediatric population. The success rate was significantly better when the fractures were treated within 24 hours of the injury. The results of the present study have strengthened the assertion that trapdoor orbital fractures pose a true surgical emergency.

Surgical treatment and reconstruction for central giant cell granuloma of the jaws: A review of 18 cases

Central giant cell granuloma (CGCG) is an uncommon benign bony lesion that occurs in the mandible and maxilla. The clinical behaviour of CGCG ranges from a slow-growing asymptomatic swelling to an aggressive lesion that presents pain, local bone destruction, root resorption and tooth displacement. Therapeutic options have varied greatly over the years. Non-surgical treatments with alpha interferon (alpha-IFN), calcitonin and corticosteroids have been described and their benefits may be worthy of consideration. Surgery is considered the traditional treatment and it is still the most accepted one, however in the literature not all authors agree on the type of surgery which should be performed. Although en bloc resection provides the lowest recurrence rate, only a few single case reports describe the use of this technique followed by reconstruction with autogenous bone grafts. The authors report their experience with en bloc resection of 18 wide CGCGs which had not been previously treated medically. Immediate reconstruction was carried out for all cases and in one, a fibula free flap was used to reconstruct the mandible. No recurrence was observed. After complete healing of the graft, prosthetic rehabilitation via implants was performed. This allowed the best functional and aesthetic results.

Management of sport-related maxillofacial injuries.

By analyzing sports-related maxillofacial fractures, we sought to describe preventive measures and recovery times until sporting activities could be resumed. Between January 2001 and December 2006, 1241 patients were hospitalized as a result of maxillofacial fractures. The patients with sports-related maxillofacial fractures were analyzed based on age, sex, type of sport, injury mechanism, trauma site, presence of associated fractures, hospitalization, treatment method, and recovery time until the resumption of sporting activities. One hundred thirty-eight patients (11.4%) sustained sports-related maxillofacial fractures: 121 males and 17 females (ratio 8:1), aged between 11 and 72 years. The sport producing the greatest number of injuries was soccer (62.3%), followed by skiing (14.5%), and horseback riding (6.5%). The injuries involved mainly the middle third of the face (71.6%), and the mandible was the most affected site (27.2%), followed by the maxillary-zygomatic-orbital complex (25.9%). Treatment was surgery in 93.5% of the patients, with an average hospitalization period of 3.5 days. The protocol created to manage the follow-up of maxillofacial injury patients advised resuming sports activities at least 40 days after the trauma, except in the case of combat sports, when a period of 3 months was required. Although the results of this study indicate a reduction in the total incidence of sports-related maxillofacial injuries, they also show an alarming secondary increase in trauma resulting from the most popular sport in Italy-soccer. Therefore, stricter regulations are needed to discourage violent play, rather than relying on the use of protective equipment. Moreover, patients should be advised when they can resume sports activities, particularly in the case of professionals and semiprofessionals.

Surgical treatment of odontogenic myxoma.

Background: There is no consensus about the surgical treatment of odontogenic myxoma. The aim of the current study was to present our experience and discuss the surgical management and outcome in 10 patients diagnosed with odontogenic myxoma. Methods: A retrospective review of charts of patients who were surgically treated for odontogenic myxoma was performed. Patients were recalled, and eventual recurrences were investigated. Results: Eight lesions were mandibular, whereas 2 were maxillary. In 3 patients, enucleation and curettage was performed. Instead, in the remaining 7 patients, segmental resection and immediate reconstruction were decided. At follow-up, no patient showed recurrence of the lesion. Conclusions: Our protocol is to perform conservative surgery by enucleation and curettage when lesions were smaller than 3 cm, whereas a segmental resection with immediate reconstruction is preferred in patients affected by bigger tumors. Long-term follow-up is required, in particular when conservative surgery is preferred.

Use of Patient and Observer Scar Assessment Scale for evaluation of facial scars treated with self-drying silicone gel.

In this prospective study, we used the Patient and Observer Scar Assessment Scale (POSAS) to evaluate the outcome of the healing process of posttraumatic and surgical facial scars that were treated with self-drying silicone gel, by both the patient and the observer. In our division, the application of base cream and massage represents the standard management of facial scars after suture removal. In the current study, 15 patients (7 men and 8 women) with facial scars were treated with self-drying silicone gel that was applied without massage, and 15 patients (8 men and 7 women) were treated with base cream and massage. Both groups underwent a clinical evaluation of facial scars by POSAS at the time of suture removal (T0) and after 2 months of treatment (T1). The patient rated scar pain, itch, color, stiffness, thickness, and surface (Patient Scale), and the observer rated scar vascularity, pigmentation, thickness, relief, pliability, and surface area (Observer Scale [OS]). The Patient Scale reported the greatest improvement in the items color, stiffness, and thickness. Itch was the only item that worsened in the group self-drying silicone gel. The OS primarily reported an improvement in the items vascularization, pigmentation, and pliability. The only item in the OS that underwent no change from T0 to T1 was surface area. The POSAS revealed satisfactory healing of posttraumatic and surgical facial scars that were treated with self-drying silicone gel.

Characteristics of maxillofacial trauma in females: A retrospective analysis of 367 patients

INTRODUCTION Epidemiological characteristics of maxillofacial injuries are typically reported for male patients, as males represent 70% of the studied population. This retrospective study analysed the aetiology and patterns of maxillofacial fractures in female patients only. MATERIAL AND METHODS A total of 367 female patients, examined between 2001 and 2008, were divided into three age groups (<16, 17-60, and >60 years). Data were collected on aetiology, fracture site, associated lesions, type of treatment, and length of hospital stay. RESULTS The typical female patient presented a mean age of 43 and 25% were over 60 years of age. Falls were the most frequent cause of maxillofacial trauma (43%), followed by motor vehicle accidents (MVAs) (38.7%), assaults (9.3%), sports accidents (6.3%), and other causes (2.7%). The middle third of the face was most frequently affected (53.9%). Associated fractures, mostly orthopaedic and secondary to MVAs, occurred in 23.2% of cases. The over-60 age group had the greatest number of non-operated fractures (27.9%) and the longest mean hospital stay (5.7 days). CONCLUSIONS This study considered only the female population, thereby highlighting epidemiological characteristics of maxillofacial trauma not apparent in the existing literature. Clear distinctions between genders are important for better comparison of data in the future.

Cervical spine fractures associated with maxillofacial trauma: an 11-year review

Although cervical spine injury is rarely associated with maxillofacial trauma, it should be suspected when injuries above the clavicle occur, as suggested in the Advanced Trauma Life Support Manual. A retrospective study of 2482 patients with maxillofacial trauma, who were admitted to the Maxillofacial Surgical Division of Turin University between 1996 and 2006, conducted to identify concomitant fractures of the cervical spine and establish a treatment protocol. Twenty-one patients (0.8%), consisting of 17 males and four females ranging in age from 15 to 70 years, had amyelic cervical spine fractures. In 90% of the cases, the cervical spine injury was caused by a road accident. Cervical spine injuries were diagnosed using lateral x-rays in three cases and with computed tomography in the remaining patients. Although an association has been reported between mandibular fracture and cervical spine injury, we did not observe a preferential association between injuries of the upper third of the face and spinal injury. Cervical spine immobilization should never be removed until cervical spine injury has been excluded using a lateral x-ray of the cervical spine. In males with significant blunt craniomaxillofacial trauma caused by high-energy impact accidents such as car and motorcycle accidents, computed tomography is the radiologic examination of first choice to exclude cervical spine injuries. Lastly, the presence of a cervical spine injury did not result in modified or delayed treatment of maxillofacial fractures, with the exception of one patient who had a fracture of the odontoid process.

Lingual nerve deficit following mandibular third molar removal: review of the literature and medicolegal considerations

The removal of mandibular third molars is probably the most frequently performed procedure in oral and maxillofacial surgery, and it is the most common surgical procedure associated with lingual nerve deficit. Lingual sensory impairment remains a clinical problem in oral and maxillofacial surgery and has serious medical and legal implications. In fact, damage to the lingual nerve is a common cause of litigation in dentistry. The purpose of this article was to review the literature about lingual nerve deficit following mandibular third molar removal and discuss the associated medicolegal aspects.
