Craniomaxillofacial Trauma & Reconstruction最新文献

Background: Naso-orbital-ethmoid (NOE) fractures represent complex midface injuries that challenge aesthetic and functional reconstruction. This study evaluates the efficacy of techniques restoring intercanthal distance following operative repair of NOE fractures.

Methods: A retrospective case series was conducted of adults undergoing NOE fracture repair between 2010 and 2022. CPT codes were used to identify patients, with inclusion based on radiographic confirmation of NOE fractures. Demographic data, fracture classification, operative techniques, and pre- and post-operative CT measurements of intercanthal distance were analyzed by fracture type and type of repair.

Results: 191 patients were identified, mostly male (80%), with Type I fractures being most common (66%). Intercanthal wiring was used in 14% of cases, most frequently for Type II and III fractures. Of the 100 patients with post-operative comparison imaging, the median intercanthal distance improved from 34 mm to 31 mm. Intercanthal wiring yielded greater median distance correction. All patients achieved restoration of intercanthal distance within normal limits regardless of repair technique.

Conclusions: Operative repair of NOE fractures using either plating or intercanthal wiring effectively restores normal intercanthal distance. While intercanthal wiring remains valuable in severe fractures, it may not be universally necessary. Further study is needed to refine the role of these repair techniques.

Background: Although orbital fractures are common in trauma care, age-specific mechanisms and admission physiology-based risk stratification have not been systematically characterized. This study aimed to identify age-mechanism interaction patterns and develop an admission-based physiological risk score for orbital fracture patients.

Methods: This retrospective cohort study analyzed 41,464 adult orbital fracture patients from the National Trauma Data Bank (2018-2020). A three-component physiological risk score was developed using admission vital signs: severe hypotension (<90 mmHg, 2 points), tachycardia (>100 bpm, 1 point), and severe traumatic brain injury (GCS ≤ 8, 1 point). Risk stratification performance was validated against composite adverse outcomes.

Results: Distinct age-mechanism patterns emerged: 74.0% of elderly patients (≥65 years) sustained falls, while young adults demonstrated a bimodal distribution with motor vehicle crashes (31.2%) and violence (28.4%). Violence-related injuries occurred in younger patients (40.3 vs. 55.0 years) but had lower injury severity scores (10.0 vs. 14.4) and mortality (2.8% vs. 5.2%) than accidental mechanisms. High-/critical-risk patients (8.4% of the cohort) had 16.2% mortality versus 2.1% in stable patients. Complex facial injuries demonstrated 11-fold higher mortality (7.7% vs. 0.7%). The physiologic risk score achieved AUC 0.79 (95% CI: 0.78-0.80).

Conclusions: Age-mechanism interactions revealed distinct bimodal injury patterns in young adults. Admission physiologic parameters effectively identify 8.4% of patients requiring intensive resources, while violence-related injuries paradoxically demonstrate better outcomes than accidental mechanisms.

Introduction: Facial trauma is a public health concern, with reports of about 25% of all traumas having a component of facial injury. Alcohol and illicit drug use have previously been shown to exacerbate the severity of trauma injuries. This study investigates the relationship between illicit drug use and clinical outcomes amongst patients presenting with facial fracture injuries.

Methods: A retrospective multicenter cohort study through the TriNetX database was performed. Drug Involved Facial fracture injury with illicit drug use (DIFFI+) was compared to a Non-Drug Involved Facial Fracture Injury group (DIFFI-). After propensity score matching, measures of hospital burden outcomes, surgical intervention, and underlying psychiatric diagnosis outcomes were compared.

Results: A total of 27,863 propensity score-matched DIFFI+ cases were used for analysis. DIFFI+ patients were younger (mean age 33.8 vs. 42.0 years, p < 0.001), more often male (75% vs. 56%, p < 0.001), and more likely to be Black/African American (21% vs. 14%, p < 0.001), with cannabis and opioid use most common. DIFFI+ patients had a significantly higher odds of hospital burden outcomes, including psychiatry services (OR = 8.40), ventilator management (OR = 5.18), and critical care services (OR = 3.83).

Conclusions/discussion: DIFFI+ was significantly correlated with greater hospital burden in all analyzed clinical outcomes. DIFFI+ patients have a higher odds of receiving surgery but lower odds of receiving a fracture diagnosis. Having a psychiatric diagnosis increases risk for DIFFI+ injury.

Zygomaticomaxillary complex (ZMC) fractures are among the most common midfacial injuries, with significant implications for both function and facial esthetics. Optimal management requires restoring the normal anatomical alignment and symmetry of the zygomatic region to prevent long-term deformity and functional deficits. However, the decision-making surrounding surgical intervention, particularly in isolated ZMC fractures with moderate displacement, remains nuanced. This review discusses contemporary surgical approaches for isolated ZMC fractures and examines how objective morphometric analysis can guide critical decisions such as the timing of surgery, choice of surgical approach, and extent of fixation. Conventional assessment tools like computed tomography (CT), cephalometric measurements, and intraoperative imaging provide foundational data on fracture anatomy. Emerging technologies, including three-dimensional (3D) photogrammetry, stereophotogrammetry, artificial intelligence (AI)-based symmetry analysis, and surgical navigation systems, offer advanced means to quantify facial symmetry and bone alignment. By integrating these objective metrics into clinical practice, surgeons can enhance preoperative planning and postoperative outcome evaluation, with a particular focus on achieving facial symmetry for optimal esthetic and functional results. We also outline clinical decision-making frameworks that incorporate quantitative measurements, and we discuss current limitations, future directions, and the potential for standardizing protocols in the management of ZMC fractures.

This meta-review evaluated the possibility of more specified recommendations in antibiotic treatment through a narrowed focus on facial trauma. The aim was to analyze the effect of different regimens of antibiotic in treatment of skeletal trauma to the face. The knowledge mapping was based on existing systematic reviews (SRs) on trials specified in a PICO: Participants (P): Adults and children, diagnosed with fractures to the facial skeleton. Interventions (I): Antibiotic intervention. Comparator (C): Placebo, no antibiotics. Outcomes (O): Postoperative infection, pain, re-operation, other complications, healing deficiencies, (Oral) Health related Quality of Life, removal of osteosynthesis, adverse reactions. The literature search in PubMed, The Cochrane Library, and Web of Science according to PRISMA resulted in 1487 records. A COVIDENCE selection process resulted in 29 articles retrieved and read in full text revealing 10 articles eligible for evaluated according to ROBIS. Three SRs were considered to have low risk of bias and constituted the final evidence evaluation. The meta-review of these SRs did not provide sufficient support for prolonged antibiotic treatment after surgical intervention of midfacial fractures in comparison with antibiotics only the first day postoperatively. No support for antibiotic treatment for conservatively managed fractures alone was found. This review is limited by a relatively low number of included SRs. However, tendencies in outcomes suggests a restricted duration of antibiotics in treatment of facial fractures.

Background: The high perimandibular approach (HPA) is a feasible surgical technique for open reduction and internal fixation (OR-IF) of mandibular condylar fractures, offering reduced complication rates. In this study, we retrospectively evaluated the treatment outcomes and complications associated with HPA use.

Patients and methods: Patients who underwent OR-IF for mandibular condylar fractures using the HPA at three hospitals in Shimane between June 2019 and March 2024 were included. Data collected included the mechanism of injury, AO classification of the fracture site, fracture type and mode, surgical duration, mouth-opening range at 6 months post-operatively, and peri- and post-operative complications.

Results: A total of 42 patients (46 condylar fractures; 18 males and 24 females; mean age, 63.0 years) were included. The fracture pattern included dislocations in 18 cases (42.8%). The mean surgical duration was 75.0 min. Post-operative trismus occurred in 16 patients (38.1%) at 6 months. Longer surgical duration and dislocated fractures were significantly associated with post-operative trismus (p < 0.05).

Conclusions: The HPA is safe and effective for managing mandibular condylar fractures. However, post-operative trismus may be influenced by longer surgical duration and fracture types, warranting further investigation and potential post-surgical management.

Computer-assisted surgery (CAS) and virtual surgical planning (VSP) have transformed jaw reconstruction, allowing immediate insertion of dental implants during surgery for better rehabilitation of occlusal function. However, traditional planning for optimal location and angulation of dental implants and fibula relies on experience and can be time-consuming. This study aimed to propose a function-driven workflow and develop an automatic computer program for optimal positioning of simultaneous dental implants and fibula segments. A customized computer program was developed using MATLAB. Computed tomography (CT) of the lower limbs of ninety-one Southern Chinese individuals was retrieved and cross-sections of three-dimensional (3D) fibula models were comprehensively investigated for implant installation. Our research proves that the accuracy of the program in identifying the anatomical orientation of the fibula was 92%. The ideal location, angulation and length of implant could be automatically generated based on any selected implant diameter, with a surgical feasibility of 94%. To the best of our knowledge, this is the first study to develop and validate a customized automatic computer program for osseointegrated implant design in fibula flap surgery. This program can be incorporated into the current workflow of CAS to further the development of reliable and efficient surgical planning for function-driven jaw reconstruction.

Background: Orthognathic surgery aims to align the jaws with the facial skeleton and correct dental occlusion. This paper introduces the concept of planning the maxillomandibular complex (MMC) as a whole, utilizing a t-forming set of landmarks: the maxillary central incisor, the chin, and the occlusal plane. Methods: The background, hypothesis, and rationale of the new T concept are explained. A case of a 28-year-old male with skeletal class III malocclusion and an open bite was used to illustrate the application of the T concept in step-by-step surgical planning. The planning encompasses four phases: Phase One involves correcting frontal deformity and various asymmetries, Phase Two involves correcting chin anterior-posterior deformity, Phase Three involves correcting anterior-posterior and vertical MMC position, and Phase Four involves correcting MMC rotation. Results: The T concept provided a structured approach to plan MMC as a whole and integrate all structures into harmony. Conclusions: The T concept provides a logical approach to MMC positioning in orthognathic surgery, addressing functional and aesthetic concerns. It acts as a checkpoint to verify MMC position, helping surgeons achieve better results and avoid compensatory procedures.

Background: This study aims to evaluate the use of the endoscopic transorbital approach for reducing frontal sinus fractures and compare its outcomes with the traditional bicoronal approach.

Methods: A retrospective comparative analysis of case studies including all patients with frontal sinus fractures treated at our institution between January 2013 and December 2023 was conducted. Patients were categorized based on treatment approach (through traumatic laceration, bicoronal, or endoscopic transorbital). For the comparative analysis, cases with associated maxillofacial fractures or cerebrospinal fluid (CSF) leakage were excluded.

Results: Out of 133 patients, 35 underwent surgery, with 6 patients treated using the endoscopic transorbital approach. This group of patients treated with the transorbital endoscopic approach demonstrated significantly shorter operative times compared to the bicoronal approach (mean 102 vs. 168 min, p = 0.021). They also had only minor complications, including temporary hypoesthesia and one transient ptosis. One patient had a minimal residual defect. The technique has been concluded to require endoscopic expertise.

Conclusions: The endoscopic transorbital approach is a safe, minimally invasive alternative to the bicoronal approach for selected anterior wall frontal sinus fractures. Proper patient selection and surgical experience are essential to achieving favorable outcomes. Studies with longer follow-up are required to assess potential late complications, such as the development of mucoceles.
