Craniomaxillofacial Trauma & Reconstruction最新文献

Study design: Retrospective Cohort Study.

Objective: Reconstruction of maxillary bone defects can be completed with vascularized and non-vascularized autografts. Cellular bone matrix allografts (CBMs), which have lineage committed bone cells, has risen as an alternative. The purpose of this study was to describe our experience and to determine the success of CBM based maxillary reconstruction in a variety of clinical scenarios.

Methods: A retrospective cohort study was designed and implemented using data from subjects who presented to the University of Louisville and were treated with a CBM for maxillary reconstruction from 2019 to 2023. Subjects were excluded if they were not treated with a CBM, data were not complete, or postoperative follow-up time was less than 3 months. Descriptive statistics were calculated for each variable. To measure the associations between the risk factors and graft success, Fisher's exact test was implemented. A P-value of <0.05 was considered significant.

Results: The sample included 48 subjects. The mean age of all subjects was 43 ± 24 years. Overall, 42 (87.5%) cases were successful. The perioperative antibiotic administered (P = 0.02), etiology (P = 0.021), and the addition of platelet rich fibrin or autograft as an adjunct influenced CBM success (P = 0.039).

Conclusions: CBMs are a viable option for reconstruction of maxillary bone defects. CBMs may be an alternative to autografts.

Study design: Prospective pre-post study.

Objective: Maxillofacial trauma presenting to the emergency department (ED) are often accompanied with complex concomitant injuries, thereby making thorough diagnosis and treatment plan quite an exacting task owing to the demanding conditions of the ED. The use of a structured maxillofacial trauma template helps in documenting the injuries comprehensively, aids in treatment planning, avoids medical negligence thereby improving the quality of care given to the patient. The study introduced a structured maxillofacial trauma template to improve the quality of the ED documentation.

Methods: A total of 220 patients were evaluated for the quality of their ED documentation from September 2023 till February 2024. The group A included 110 patients where complete medical documentation was done routinely on a blank A4 sized paper, group B included 110 patients where the documentation was done using the structured oral and maxillofacial trauma template. The ED notes were thoroughly evaluated by the 2 independent authors for record completeness and documentation rate of history and examination findings.

Results: The introduction of trauma template demonstrated a significant improvement of 18.95 % in record completeness. Significant improvement was seen in documentation rate among the covariates like place of injury, time of evaluation, primary care given, wound classification, dento-alveolar injury, ophthalmic evaluation, nerve injury evaluation, comorbidities with P = .001, and referral with P = .03. The ophthalmic evaluation showed significant improvement among covariates (loss of visual acuity, reflexes, diplopia, enophthalmos, subconjunctival haemorrhage, chemosis, periorbital oedema, periorbital ecchymosis, ocular dystopia) with P = .001, and extraocular muscle restriction with P = .004.

Conclusions: The study demonstrated that the use of a structured oral and maxillofacial trauma template can significantly improve the quality of the ED documentation and contributes to better patient care in the ED.

Study design: Submental intubation is and underutilized alternative to traditional techniques of intubation. Complications associated can indeed deter surgeons and anesthesiologist from performing it. Surgeons may opt for submental intubation if they believe that its advantages outweigh the potential risks of the procedure. Identifying the reasons of complications and implementing of proper strategies to address them can help mitigate risks.

Objective: This study aims to compare and analyze the complications experienced during and after submental intubation to comment on its safety, efficacy. Revisiting literature, will help us to comment on diagnosis in trauma and associated perioperative and intraoperative complication with it. It will also help us deduce most preferred way of performing submental intubation and various methods to manage complications.

Methods: Submental intubation in patients experiencing craniofacial trauma was reviewed retrospectively for 9 years from January 2015 to August 2023. Common diagnosis sites were analyzed for perioperative and postoperative complications.

Results: It was found that there were no much complications faced perioperatively and also notes methods used for management of complications. Most commonly encountered postoperative complication was scar. Literature of past years was reviewed, during process we also came out with novel method for safe extubation for which we have got copyright from Government of India.

Conclusions: Submental intubation is a safe and efficient intraoperative airway management technique for patients with craniomaxillofacial injuries when there is concurrent facial trauma. This study findings would underscore the safety and efficacy of SEI, making it a promising unparalleled method of airway management worth considering.

Study design: National database study.

Objective: Road traffic accidents (RTAs) are a common and challenging cause of facial fractures in the United States. The present study sought to utilize the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS) to investigate national trends, injury patterns and disparities in facial fractures secondary to RTAs. To date, this is the first study to do so.

Methods: A retrospective analysis was conducted of patients with primary facial fractures secondary to RTAs using the 2018-2021 HCUP-NIS. Patients were classified into the RTA and non-RTA group. Demographics, injury patterns, and inpatient outcomes were compared.

Results: In total, 154,185 primary facial fractures were identified, of which 17% (n = 26,115) were associated with RTAs. RTAs commonly involved cars (41%), followed by motorcycles (15%), pedestrians (11%), and bicyclists (10%). The RTA group was younger (34% vs 24% < 25 years, P < .01) and more frequently Hispanic (18% vs 15%, P < .01). The most common fracture types were mandibular (23%), frontal (14%), and orbital fractures (14%). The RTA group was 50% more likely to have multiple facial fractures (OR = 1.5, P < .01). The RTA group had a longer length of stay (5.3 vs 4.0 days, P < .01), admission charge ($127,932 vs $79,414, P < .01), and mortality rate (1.9% vs 1.4%, P < .01) than the non-RTA group.

Conclusions: The present findings provide valuable insights, informing early involvement of craniofacial surgeons for the assessment of combination facial fractures and tailored treatment approaches for RTA patients.

Study design: Single-institution retrospective financial analysis.

Objective: Trauma care is consistently linked to inadequate reimbursement, posing a significant financial burden for large trauma centers. Data show that declining Medicare reimbursement rates have indirectly led to declining payment for all procedures covered by insurance. The goals of this study are to investigate the opportunity cost associated with contemporary surgical management of CMF trauma at our institution and to evaluate longitudinal financial trends.

Methods: Patients with operative facial fractures between 2015 and 2022 at Duke University Medical Center were included and compared to patients undergoing general otolaryngology, plastic surgery and oral surgery operations in the same period. Procedural codes, payor type, charges billed, collections, relative value units (RVUs) and other financial data were obtained and analyzed among the 2 patient populations. Comparative analysis was performed to assess the financial trends in data reported previously from 2007-2015.

Results: The collection rate at Duke University Medical Center for operatively managed CMF fractures remains significantly lower than non-CMF counterparts. Interestingly, the collection rate gap between CMF and non-CMF surgeries has narrowed when comparing to the data from 2007-2013. This is largely due to a decrease in collection rates for non-CMF procedures from 29.61% (2007-2013) to 26.57% (2015-2022) [P = 0.0001] and an increase in collection rates for CMF procedures from 17.25% (2007-2013) to 18.05% (2015-2022) [P = 0.0001].

Conclusions: Despite a slight improvement of the gap in reimbursement rates for CMF and non-CMF surgeries over the last several years, trauma care continues to have a negative financial impact on health care institutions.

Study design: Retrospective cohort study.

Objective: Calvarial osteoradionecrosis (ORN) is a rare but devastating complication of radiotherapy. The aim of this study was to describe the cumulative incidence of Calvarial ORN in patients in patients treated for cutaneous malignancy of the scalp.

Methods: Data was compiled from patient records of a large tertiary hospital Plastic Surgery department and radiotherapy records of an affiliated cancer Center. We included all patients that were treated for cutaneous malignancies of the scalp that received radiotherapy. Patient demographics, cancer stage, treatment modalities, intraoperative details, and patient outcome data were recorded. Patients with incomplete radiotherapy data were excluded.

Results: We analyzed 105 radiotherapy treatments to the scalp administered to 84 patients and recorded 7 cases of calvarial ORN resulting in a gross incidence of 6.67% per radiotherapy treatment. The parietal bone was the most frequently targeted site of radiotherapy and accordingly the most common site of ORN (85.7%). Median time from radiotherapy dose to the development of ORN was 846 days. Higher number of radiotherapy fractionation (P = .038), cumulative radiotherapy dose (P = .035), prolonged radiotherapy duration (P = .022) and skin grafting (P = .003) were associated with the development of ORN.

Conclusions: Our findings suggest radiotherapy variables, such as prolonged radiotherapy duration, increased cumulative dose and higher radiotherapy fractions were strongly associated with the development of ORN. In addition, skin grafting following surgical resection was associated with the development of ORN. Further studies with larger sample sizes are required to further explore this relationship.

Study design: A retrospective study.

Objective: The Markowitz-Manson classification system categorizes nasoorbitoethmoid (NOE) fractures by severity of injury and remaining integrity of the medial canthal tendon. However, this system does not account for direction of bony displacement (in-fracture vs out-fracture), which can greatly affect symptomatology and management. We hypothesize that NOE fractures will present differently based upon their severity: Type I injuries are likely to present with medial nasal bone displacement (in-fracture), whereas Type III fractures will be more prone to lateral displacement (out-fracture).

Methods: A retrospective review was performed for all patients with NOE fractures who were evaluated by the plastic surgery department at a level 1 trauma center over a 6-year period. Computed tomography data were evaluated to assess for directionality of fracture segment displacement. Frequencies of medial, lateral, and non-displacement across NOE types were compared by Chi-Squared Goodness of Fit and Fisher's Exact Tests.

Results: 111 patients met inclusion criteria. The patient population was 73.9% male and averaged 51.2 years old. When bilateral fractures were counted independently, there were 141 cases in total: 115 Type I, 20 Type II, and 6 Type III. Type I fractures were most commonly in-fractured (48.7%), while Type III injuries were consistently out-fractured (100%) (p < .001).

Conclusions: While Type II and III NOE fractures have dominated clinical focus, this study highlights the prevalence of impaction within Type I fractures. These findings advocate for a more comprehensive approach to the evaluation of Type I NOE fractures and their potential risks, including traumatic hypotelorism and nasal airway obstruction.
