Recent advances in the management of oral and maxillofacial trauma

Knowledge, Perception, and Awareness of the Specialty of Oral and Maxillofacial Surgery Among the Public and Medical Field in Hail, Saudi Arabia: A Cross-Sectional Study

Aim and background Oral and maxillofacial surgery is a crucial medical specialty focused on diagnosing, treating, and preventing diseases and injuries affecting the oral cavity, jaw, and face. There is a lack of awareness about this field in the specific study area of hail. This study aimed to assess the knowledge, awareness, and perception of maxillofacial surgery among healthcare professionals and the public. Methods The study included 225 participants, consisting of dental and medical professionals and the general public in Hail, Saudi Arabia. Convenience sampling was employed, and participants needed to be at least 20 years old and residents of Hail. A validated online questionnaire, translated into Arabic, was used for data collection. Results A proportion (78.2%) of dental professionals were aware of the specialty of oral and maxillofacial surgery. Among the general population and most medical professionals, the most commonly associated procedures with maxillofacial surgery were the treatment of injuries, bone fractures, and morphological changes in the mouth, jaw, and face, reported by 85.8% of the participants. Furthermore, 60.9% of the participants believed that maxillofacial surgery was the appropriate referral for cleft lip correction. Conclusion The study highlighted significant knowledge about the role of oral and maxillofacial surgeons among the target population. Out of the 225 participants, 137 participants (60.9%) chose the specialty of maxillofacial surgery for surgical intervention to treat cleft lips. Moreover, 75.1% (n = 169) of the participants had previously heard about oral and maxillofacial surgery, while 24.9% (n = 56) had never heard of this specialty. The findings also showed that 189 participants were not aware that a maxillofacial surgeon is responsible for treating severe deformities that cannot be eliminated using orthodontics, such as growth disorders, hypoplasia and hypoplasia of the lower jaw, and asymmetry of the lower jaw (prognathism and retrognathism of the jaw). To bridge this knowledge gap, it is crucial to implement targeted educational initiatives and awareness campaigns among both the general population and healthcare professionals. By increasing awareness and understanding of the specialized role of oral and maxillofacial surgeons, patient care can be optimized, and appropriate referrals to these specialists can be ensured. Clinical significance This study shows the importance of increasing awareness of oral and maxillofacial surgery among health professionals and the general public. Improved understanding of this specialty can lead to better patient outcomes and early referrals.

Prosthetic Oral Rehabilitation with CAD/CAM Suprastructures in Patients with Severe Tissue Deficits: A Case Series

This article presents the outcomes of prosthetic oral rehabilitation using CAD/CAM telescopic bar overdentures in patients with oral cancer (n = 3), severe facial trauma (n = 2), or various syndromes (n = 1), all suffering from severe tissue deficits and requiring complex and comprehensive oral rehabilitation. The aim was to assess the durability and functionality of implant-retained prosthetic structures, ensuring easy oral hygiene and minimizing specialized follow-up needs. The data for this study were sourced from a retrospective cohort at Helsinki University Hospital. The prosthetic reconstruction encompassed the Atlantis 2in1 and the Createch removable telescopic systems. Thus, 40 implants were placed (4 to 7 per patient), with prosthetic structures in the maxilla (n = 4 patients), in the mandible (n = 1), and in both jaws (n = 1). Two patients experienced no complications, two patients had part of the acrylic resin break, and one patient experienced loosening of the bar structure. All complications associated with prosthetic structures were successfully managed, and none of the implants were lost. The follow-up time ranged from 7 to 126 months. This rehabilitation is proved to be an effective solution for patients with complex oral conditions, facilitating both functional restoration and ease of maintenance. These findings underscore the importance of individualized treatment approaches in cases of tissue deficits.

Virtual surgical planning is a useful tool in the surgical management of mandibular condylar fractures

PURPOSE

The aim of this study is to evaluate the application value of virtual surgical planning in the management of mandibular condylar fractures and to provide a reliable reference.

METHODS

This was a prospective randomized controlled study and recruited 50 patients requiring surgical treatment for their mandibular condylar fractures. The inclusion criteria were patients (1) diagnosed with a condylar fracture by two clinically experienced doctors and required surgical treatment; (2) have given consent for the surgical treatment; and (3) had no contraindications to the surgery. Patients were excluded from this study if: (1) they were diagnosed with a non-dislocated or only slightly dislocated condylar fracture; (2) the comminuted condylar fracture was too severe to be treated with internal reduction and fixation; or (3) patients could not complete follow-up for 3 months. There were 33 male and 17 female patients with 33 unilateral condylar fractures and 17 bilateral condylar fractures included. The 50 patients were randomly (random number) divided into control group (25 patients with 35 sides of condylar fractures) and experimental group (25 patients with 32 sides of condylar fractures). Virtual surgical planning was used in the experimental group, but only clinical experience was used in the control group. The patients were followed up for 1, 3, 6 and 12 months after operation. Variables including the rate of perfect reduction by radiological analysis, the average distance of deviation between preoperative and postoperative CT measurements using Geomagic software and postoperative clinical examinations (e.g., mouth opening, occlusion) were investigated for outcome measurement. SPSS 19 was adopted for data analysis.

RESULTS

The average operation time was 180.60 min in the experimental group and 223.2 min in the control group. One week postoperatively, CT images showed that the anatomic reduction rate was 90.63% (29/32) in the experimental group and 68.57% (24/35) in the control group, revealing significant difference (X² = 4.919, p = 0.027). Geomagic comparative analysis revealed that the average distance of deviation was also much smaller in the experimental group than that in the control group (0.639 mm vs. 0.995 mm; t = 3.824, p < 0.001).

CONCLUSION

These findings suggest that virtual surgical planning can assist surgeons in surgical procedures, reduce operative time, and improve the anatomic reduction rate & accuracy, and thus of value in the diagnosis and treatment of condylar fractures.

Helmet chinstrap protective role in maxillofacial blast injury

BACKGROUND

The protective role of helmet accessories in moderating stress load generated by explosion shock waves of explosive devices is usually neglected.

OBJECTIVE

In the presented study, the protective role of the helmet chinstrap against the impulse and overpressure experienced by the maxillofacial region were examined.

METHODS

The explosion shock wave and skull interaction were investigated under three different configurations: (1) unprotected skull, (2) skull with helmet (3) skull with helmet and chinstrap. For this purpose, a 3D finite element model (FEM) was constructed to mimic the investigated biomechanics module. Three working conditions were set according to different explosive charges and distances to represent different load conditions. Case 1: 500 mg explosive trinitrotoluene (TNT), 3 cm, case 2: 1000 mg TNT, 3 cm, and case 3: 1000 mg TNT and 6 cm distance to the studied object. The explosion effect was discussed by examining the shock wave stress flow pattern. Three points were selected on the skull and the stress curve of each point position were illustrated for each case study.

RESULTS

The results showed that the helmet chinstrap can reduce the explosive injuries and plays a protective role in the maxillofacial region, especially for the mandible.

Treatment of Facial Fractures at a Level 1 Trauma Center: Do Medicaid and Non-Medicaid Enrollees Receive the Same Care?

BACKGROUND

Timing of surgical treatment of facial fractures may vary with the patient age, injury type, and presence of polytrauma. Previous studies using national data sets have suggested that trauma patients with government insurance experience fewer operations, longer length of hospital stay (LOS), and worse outcomes compared with privately insured patients. The objective of this study is to compare treatment of facial fractures in patients with and without Medicaid insurance (excluding Medicare).

METHODS

All adults with mandibular, orbital, and midface fractures at a Level 1 Trauma Center between 2009 and 2018 were included. Statistical analyses were performed to assess the differences in the frequency of surgery, time to surgery (TTS), LOS, and mortality based on insurance type.

RESULTS

The sample included 1541 patients with facial fractures (mandible, midface, orbital), of whom 78.8% were male, and 13.1% (208) were enrolled in Medicaid. Mechanism of injury was predominantly assault for Medicaid enrollees and falls or motor vehicle accidents for non-Medicaid enrollees (P < 0.001). Patients with mandible and midface fractures underwent similar rates of surgical repair. Medicaid enrollees with orbital fractures underwent less frequent surgery for facial fractures (24.8% versus 34.7%, P = 0.0443) and had higher rates of alcohol and drug intoxication compared with non-Medicaid enrollees (42.8% versus 31.6%, P = 0.008). TTS, LOS, and mortality were similar in both groups with facial fractures.

CONCLUSIONS

Overall, the treatment of facial fractures was similar regardless of the insurance type, but Medicaid enrollees with orbital fractures experienced less frequent surgery for facial fractures. Further studies are needed to identify specific socioeconomic and geographic factors contributing to these disparities in care.

Key points in surgical management of mandibular condylar fractures

Mandibular condylar fractures are among the most common facial fractures and some of the most difficult to manage. Opinions about the management of mandibular condylar fractures differ among surgeons. With the implementation of new technology, an increased understanding of fracture management, and better functional and morphological outcomes reported in the literature, open reduction and internal fixation is becoming many surgeons' preferred choice for the treatment of condylar fractures. Because surgical treatment of such fractures is complex, certain factors must be considered to achieve satisfactory outcomes. In this article, we summarise six key points in the management of mandibular condylar fractures: virtual evaluation of condylar fracture, a suitable surgical approach, good reduction, stable internal fixation, repair of the articular disc, and restoration of the mandibular arch width. We believe that these points will help to improve the prognosis of mandibular condyle fractures.

Controversy about the protective role of volume in the frontal sinus after severe head trauma: larger sinus equates with higher risk of death

The "crumple zone" hypothesis suggests that the paranasal sinuses protect the brain as a zone to distribute and absorb energy after trauma to the head. We investigated the relation between the size of the frontal sinus and mortality in patients with cranial trauma. All patients with head trauma admitted to the ICU between 1 January 2016 and 20 December 2017 were reviewed retrospectively. They were divided into two groups (according to their outcome) : died and survived. The volumes of the frontal sinuses and other trauma-related variables were assessed on computed tomographs (CT) on admission. Admission CT of 33 patients (24 male, and nine female, aged between 18-92 years, mean 43) were obtained. Male patients had significantly larger frontal sinuses than female (10.24 compared with 6.6cm³). Larger sinuses were significantly associated with a worse outcome (p=0.005). The size of the frontal sinus correlates with mortality after cranial trauma. Our findings do not confirm the "crumple zone" hypothesis, and suggest that the larger the sinus, the greater the risk of death. To our knowledge this is a new finding that warrants further validation.

Maxillofacial injuries in severely injured patients after road traffic accidents-a retrospective evaluation of the TraumaRegister DGU® 1993-2014

Objectives

It was the aim of the study to analyse the prevalence of maxillofacial trauma (MFT) in severely injured patients after road traffic accidence (RTA) and to investigate associated factors.

Materials and methods

In a retrospective study, data from patients after RTA by the TraumaRegister DGU® from 1993 to 2014 were evaluated for demographical and injury characteristics. The predictor variable was mechanism of injury and the outcome variables were type of injury, severity and hospital resources utilization.

Results

During the investigation period, n = 62,196 patients were enclosed with a prevalence of maxillofacial injuries of 20.3% (MFT positive). The injury severity score of MFT-positive patients was higher than in the MTF-negative subgroup (27 ± 12.8 vs. 23.0 ± 12.7). If MFT positive, 39.8% show minor, 37.1% moderate, 21.5% serious and 1.6% severe maxillofacial injuries. Injuries of the midface occurred in 60.3% of MTF-positive patients. A relevant blood loss (> 20% of total blood volume) occurred in 1.9%. MFT-positive patients had a higher coincidence with cervical spine fractures (11.3% vs. 7.8%) and traumatic brain injuries (62.6% vs. 34.8%) than MFT-negative patients. There was a noticeable decrease in the incidence of facial injuries in car/truck drivers during the study period.

Conclusions

Every 5th patient after RTA shows a MFT and the whole trauma team must be aware that this indicates a high prevalence of traumatic brain and cervical spine injuries.

Clinical relevance

Even if sole injuries of the face are seldom life threatening, maxillofacial expertise in interdisciplinary trauma centres is strongly recommended.

Update on the management of craniomaxillofacial trauma in low-resource settings

PURPOSE OF REVIEW

Craniomaxillofacial (CMF) trauma is a common cause of global morbidity and mortality. Although in high resource settings the management of CMF trauma has improved substantially over the past several decades with internal rigid fixation technology; these advancements have remained economically unviable and have not yet reached low and middle-income countries (LMICs) en masse. The purpose of this review is to discuss the current management of CMF injuries in low-resource settings.

RECENT FINDINGS

Trauma injuries remain a global epidemic with head and neck injuries among the most common. CMF trauma injuries largely occur in LMICs, with motor vehicle trauma being a common cause. Patients present in a delayed fashion which increases complications. Diagnostic methods are often limited to plain radiographs as computed tomography is not always available. In low-resource settings, CMF trauma continues to be treated primarily by closed reduction, maxillomandibular fixation, and transosseous wiring, yielding acceptable results through affordable methods. With the advent of less expensive plating systems, internal fixation with plates and screws are gradually finding their place in the management of facial trauma in low-resource settings. A shortage of CMF surgeons in LMICs is a recognized problem and is being addressed by targeted curricula.

SUMMARY

CMF trauma is a major cause of morbidity and mortality globally that remains poorly addressed. Currently, conventional methods of treating CMF trauma in low-resource settings have evolved to meet resource constraints. The education of CMF surgeons remains a key leverage point in improving CMF trauma care globally.

The Effect of Local Rosuvastatin on Mandibular Fracture Healing

Mandibular fracture is the most common injury seen in facial fractures and plays an important role for oral and maxillofacial surgery department. The purpose of this study is to investigate the potential of the local administration of rosuvastatin (RSV) on mandibular fracture healing in rats. Thirty-two rats were divided into 4 groups: group C-14 (control), group R-14, group C-28 (control), and group R-28. A unilateral standard vertical osteotomy was performed right side of the mandibula extending from the tooth to the mandibular basis for each animal. In groups C-14 and C-28 sterile saline treated absorbable collogen sponge was applied to the fracture area, in groups R-14 and R-28 absorbable collogen sponge with saline solution containing 1 mg RSV was applied to the fracture area. Animals in groups C-14 and R-14 were euthanized on the 14th day, groups C-28 and R-28 were euthanized on the 28th day after operation. Stereologic analyses were performed. New bone area and connective tissue volumes were measured. Stereologic analysis showed that group R-14 had significantly more new bone at 2 weeks compared with group C-14. Connective tissue volumes were also significantly higher in R-14. New bone and connective tissue volume differences were not statistically significant between groups C-28 and R-28. Locally administered RSV enhances early bone regeneration on mandibular fracture in rats.
