The need for craniofacial trauma and oncologic reconstruction in global surgery

Bridging Gaps in Surgical Care: Facial Trauma Management Through the Surgeons in Humanitarian Alliance for Reconstruction, Research, and Education Initiative

Facial trauma presents a significant healthcare challenge in low- and middle-income countries (LMICs) due to limited access to specialized surgical care. This case report describes the management of a complex forehead degloving injury in a 20-year-old woman in Somalia, highlighting the role of remote surgical mentorship in resource-limited settings. The patient sustained a right forehead degloving injury in a motor vehicle collision, exposing a 3 × 5 cm segment of the frontal bone. Initial debridement resulted in a large soft-tissue defect, and the local surgical team faced challenges in selecting an optimal reconstructive approach due to limited experience and resources. The patient's aesthetic concerns further complicated decision-making. Through the Surgeons in Humanitarian Alliance for Reconstruction, Research, and Education program, the team sought virtual expert consultation via a secure WhatsApp platform. Based on expert recommendations, conservative management with daily Vaseline dressings was initiated to promote granulation tissue formation. Over 6 weeks, complete bone coverage was achieved, followed by full-thickness skin grafting, resulting in a satisfactory aesthetic outcome. This case demonstrates the value of global surgical networks in guiding complex reconstructions in LMICs, allowing local teams to deliver high-quality care despite resource constraints. Although short-term results were successful, long-term follow-up is necessary to assess functional and aesthetic durability. The success of this case underscores the importance of international collaborations in improving surgical education, patient outcomes, and sustainability of reconstructive techniques in LMICs.

The State of Craniomaxillofacial Trauma Care in Low- and Middle-Income Countries: A Scoping Review

Objective

This scoping review aims to contribute a descriptive analysis of the craniomaxillofacial trauma (CMF trauma) literature in low- and middle-income countries (LMICs) to identify knowledge gaps, direct future research, and inform policy.

Data Sources

PubMed/MEDLINE, Cochrane Review, EMBASE, ClinicalTrials.gov, and Google Scholar from January 1, 2012 to December 10, 2023.

Review Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guided reporting, and the PRISMA flowchart documented database searches. Specific, predefined search terms and inclusion criteria were used for screening, and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used for quality assessment. The search yielded 54 articles, with 13 meeting the inclusion criteria. Key findings were summarized and divided into 7 categories.

Results

There were 10,420 patients (7739 [74.3%] male, 2681 [25.7%] female) with a male-to-female ratio of 2.9:1. The mean peak age of incidence of CMF trauma was 30.8 years, ranging from 20 to 40 years. Road traffic accidents were the leading cause (60.4%), followed by assault (27.2%) and falls (12.2%). The most common injuries were soft tissue injury (31.7%), isolated mandibular fracture (22.8%), and isolated middle-third of mandible fracture (18.1%). The most common treatments were closed reduction and immobilization (29.5%), conservative management (27.6%), and open reduction and internal fixation (19.6%). Most patients (77.8%) experienced a treatment delay due to a lack of fixation materials (54.8%) or surgeon unavailability (35.7%).

Conclusion

CMF trauma remains a significant cause of global morbidity, yet there remains a lack of high-quality, CMF trauma-specific data in LMICs. Country-specific investigations are required to enhance knowledge and inform novel interventions. Implementing policy change must be community-specific and account for unique cultural barriers, attitudes, and behaviors to maximize patient care outcomes.

Off-Label Use of an External Hand Fixator for Craniomaxillofacial Fractures-An Anatomical Feasibility Study

BACKGROUND

The lack of resources limits the treatment of craniomaxillofacial fractures (CMF) in low-income countries (LIC). Therefore, Barton bandages and/or interdental wiring are considered in these regions. Fracture reduction is maintained by permanent occlusion for 6 weeks, which often leads to limited compliance and dissatisfying results. The aim of this cadaver-based study is to evaluate the feasibility of the use of an external face fixator (EFF) for the treatment of CMF, its biomechanical values and to define the optimal pin insertion points and angles.

MATERIALS AND METHODS

An AO hand fixator was used. CMF of types Le Fort 1-3 with split fractures of the hard palate were treated with EFF on 13 anatomical specimens. Fractures were created using a chisel, and pins were placed in specific anatomical regions. The maximal pull-out force [N] of pins was analysed by a tensile force gauge, and Fmax of the mandibular pins was evaluated. Computer tomography scans were performed on the healthy, fractured and EFF-treated skulls.

RESULTS

The pull-out forces for the single pins were mandibular pins (n = 15, median 488.0 N), supraorbital pins (n = 15, median 455.0 N), zygomatic pins (n = 14, median 269.1 N), medial hard palate pins (n = 12, median 208.4 N) and lateral hard palate pins (n = 8, median 49.6 N).

CONCLUSIONS

The results indicate that the operation technique is feasible, and the stability of the EFF is sufficient for maintaining the reduction. The required pins can safely be inserted into the described areas with good reduction results. Using EFF offers a feasible alternative to the non-surgical treatment of CMF in LIC.

Enhancing Craniofacial Bone Reconstruction with Clinically Applicable 3D Bioprinted Constructs

Medical imaging and 3D bioprinting can be used to create patient-specific bone scaffolds with complex shapes and controlled inner architectures. This study investigated the effectiveness of a biomimetic approach to scaffold design by employing geometric control. The biomimetic scaffold with a dense external layer showed improved bone regeneration compared to the control scaffold. New bone filled the defected region in the biomimetic scaffolds, while the control scaffolds only presented new bone at the boundary. Histological examination also shows effective bone regeneration in the biomimetic scaffolds, while fibrotic tissue ingrowth is observed in the control scaffolds. These findings suggest that the biomimetic bone scaffold, designed to minimize competition for fibrotic tissue formation in the bony defect, can enhance bone regeneration. This study underscores the notion that patient-specific anatomy can be accurately translated into a 3D bioprinting strategy through medical imaging, leading to the fabrication of constructs with significant clinical relevance.

Patterns of Head and Neck Injuries in Urban India: A Multicenter Study

Objective

The pattern of head and neck injuries has been well studied in high-income countries, but the data are limited in low- and middle-income countries, which are disproportionately affected by trauma. We examined a prospective multicenter database to describe patterns and outcomes of head and neck injuries in urban India.

Study Design

Retrospective review of trauma registry.

Setting

Four tertiary public hospitals in Mumbai, Delhi, Kolkata.

Methods

We identified patients with isolated head and neck injuries using International Classification of Diseases, 10th Revision (ICD-10) codes and excluded those with traumatic brain and/or ophthalmic injuries and injuries in other body regions.

Results

Our cohort included 171 patients. Most were males (80.7%) and adults aged 18 to 55 years (60.2%). Falls (36.8%) and road traffic accidents (36.3%) were the 2 predominant mechanisms of injury. Overall, 35.7% required intensive care unit (ICU) admission, and 11.7% died. More than 20% of patients were diagnosed with “unspecified injury of neck.” Those with the diagnosis had a higher ICU admission rate (51.4% vs 31.3%, P = .025) and mortality rate (27.0% vs 7.5%, P = .001) than those without the diagnosis.

Conclusion

Isolated head and neck injuries are not highly prevalent among Indian trauma patients admitted to urban tertiary hospitals but are associated with high mortality. Over a fifth of patients were diagnosed with “unspecified injury of neck,” which is associated with more severe clinical outcomes. Exactly what this diagnosis entails and encompasses remains unclear.
