RESUMO
BACKGROUND: Early identification of non-fatal strangulation in the context of intimate partner violence (IPV) is crucial due to its severe physical and psychological consequences for the individual experiencing it. This study investigates the under-reported and underestimated burden of IPV-related non-fatal strangulation by analysing assault-related injuries leading to anoxia and neck injuries. METHODS: An IRB-exempt, retrospective review of prospectively collected data were performed using the National Electronic Injury Surveillance System All Injury Programme data from 2005 to 2019 for all assaults resulting in anoxia and neck injuries. The type and mechanism of assault injuries resulting in anoxia (excluding drowning, poisoning and aspiration), anatomical location of assault-related neck injuries and neck injury diagnosis by morphology, were analysed using statistical methods accounting for the weighted stratified nature of the data. RESULTS: Out of a total of 24 493 518 assault-related injuries, 11.6% (N=2 842 862) resulted from IPV (defined as perpetrators being spouses/partners). Among 22 764 cases of assault-related anoxia, IPV accounted for 40.4%. Inhalation and suffocation were the dominant mechanisms (60.8%) of anoxia, with IPV contributing to 41.9% of such cases. Neck injuries represented only 3.0% of all assault-related injuries, with IPV accounting for 21% of all neck injuries and 31.9% of neck contusions. CONCLUSIONS: The study reveals a significant burden of IPV-related anoxia and neck injuries, highlighting the importance of recognising IPV-related strangulation. Comprehensive screening for IPV should be conducted in patients with unexplained neck injuries, and all IPV patients should be screened for strangulation events.
RESUMO
Patients presenting with laryngotracheal trauma can be in a life-threatening situation. Early recognition of the severity of the injury and, if necessary, surgical intervention within the first 24-48â¯h increases the chance of achieving a good functional late result. Preservation or restoration of voice and swallowing function is the long-term therapeutic goal. Precise assessment of the extent of the injury can be achieved using a combination of computed tomography and flexible laryngotracheoscopy. Symptoms often do not reflect the extent of the injury, which can vary from endolaryngeal hemorrhage to complete laryngotracheal separation. Conservative treatment consists of observation with symptomatic therapy. On the other hand, surgery may include endolaryngeal repair and/or transcervical reconstruction; securing the airways is of utmost importance.

BACKGROUND: Airway management of patients with direct airway trauma caused by penetrating neck injuries is always challenging. When a failed airway occurs and surgery access is difficult, it is crucial to find the optimal approach to save the life. We propose the concept "Cannot intubate, Cannot oxygenate, Difficult surgery access" to describe this emergency scenario. CASE PRESENTATION: We report a case of a 24-year-old woman who presented with partial tracheal rupture and pneumothorax caused by a knife stab injury to the neck. A "double setup" strategy, simultaneous preparation for orotracheal intubation and tracheotomy, was carried out before rapid sequence induction. A tracheotomy under local anesthesia or an awake intubation was not preferred in consideration that the patient had a high risk of being uncooperative owing to existing mental disease and potential smothering sensation during operation. During rapid sequence intubation, distal part of the tube penetrates the tear and creates a false lumen outside the trachea then a failed airway subsequently occurred. Rescue tracheotomy was successfully performed by an otolaryngology surgeon, with the help of limited ventilation using sequential bag-mask and laryngeal mask airway ventilation provided by an anesthesiologist, without severe sequelae. CONCLUSIONS: The endotracheal tube have a risk of penetrating the tear outside the trachea in patient with partial tracheal rupture during orotracheal intubation, and once it occurs, proceeding directly to an emergency invasive airway access with optimizing oxygenation throughout procedure might increase the chance of success in rescuing the airway.

HISTORY: A 21-year-old female was injured by accidental strangulation. Dyspnea and stridor occurred with delay, and led to emergency intubation. FINDINGS: Physical examination showed strangulation marks and neck emphysema. Computed tomography confirmed laryngotracheal separation and revealed misplacement of the ventilation tube. DIAGNOSIS: Further surgical exploration revealed complete laryngotracheal (cricotracheal) separation. TREATMENT: After initial emergency tracheotomy, cricotracheal reanastomosis was achieved by a two-stage surgical approach. CONCLUSION: Laryngotracheal separation is associated with high mortality. In the case presented herein, the patient survived and was discharged from hospital without a tracheostomy tube despite bilateral recurrent laryngeal nerve palsy.

OBJECTIVES: Although laryngohyoid fracture indicates the applied neck pressure and is an important finding in hanging individuals, the reported rate varies widely and its true incidence remains controversial. We used computed tomography (CT) studies to investigate the incidence of laryngohyoid fracture in hanging individuals and identify factors contributing to such fractures. METHODS: Considered for inclusion in this study were 107 attempted or successful hanging individuals subjected to CT studies between 2005 and 2019. After excluding 19 whose images were inadequate for evaluation, 88 subjects were included. Body suspension was complete in 20, partial in 49, and unknown in 19; 54 (61.4%) individuals died. Two radiologists performed image analysis and recorded the presence and site of laryngohyoid fractures. Multiple logistic regression analysis was used for factor analysis of laryngohyoid fractures; it included the gender, the age (< or ⧠40 years), the type of suspension (complete or incomplete), and the outcome (death or survival). RESULTS: Of the 88 subjects, 35 (39.8%) presented with laryngohyoid fractures on CT images; the superior horn of the thyroid cartilage was fractured in 32 (91.4%) of the 35. Age was the only factor significantly related to laryngohyoid fracture (odds ratio = 2.85, 95% confidence interval = 1.08-7.52). CONCLUSIONS: In hanging individuals, the incidence of laryngohyoid fracture on CT images was 39.8%. The superior horn of the thyroid cartilage was the most frequent fracture site. KEY POINTS: ⢠The incidence of laryngohyoid fracture on CT images of hanging individuals was almost 40%; the superior horn of the thyroid cartilage was the most frequent fracture site. ⢠In older hanging individuals, attention must be paid to laryngohyoid fractures on CT images.

PURPOSE: The management of cervical facet dislocation injuries remains controversial. The main purpose of this investigation was to identify whether a surgeon's geographic location or years in practice influences their preferred management of traumatic cervical facet dislocation injuries. METHODS: A survey was sent to 272 AO Spine members across all geographic regions and with a variety of practice experience. The survey included clinical case scenarios of cervical facet dislocation injuries and asked responders to select preferences among various diagnostic and management options. RESULTS: A total of 189 complete responses were received. Over 50% of responding surgeons in each region elected to initiate management of cervical facet dislocation injuries with an MRI, with 6 case exceptions. Overall, there was considerable agreement between American and European responders regarding management of these injuries, with only 3 cases exhibiting a significant difference. Additionally, results also exhibited considerable management agreement between those with ≤ 10 and > 10 years of practice experience, with only 2 case exceptions noted. CONCLUSION: More than half of responders, regardless of geographical location or practice experience, identified MRI as a screening imaging modality when managing cervical facet dislocation injuries, regardless of the status of the spinal cord and prior to any additional intervention. Additionally, a majority of surgeons would elect an anterior approach for the surgical management of these injuries. The study found overall agreement in management preferences of cervical facet dislocation injuries around the globe.

PURPOSE: Pseudoaneurysms of the common carotid artery secondary to high-velocity fragment injuries to the head and neck in patients are uncommon lesions. Multi-detector computed tomography angiography should be performed on all patients suffering from high-speed fragment injuries of the head and neck. CASE PRESENTATION: We share our experience with the endovascular management approach for the closure of 2 separate pseudoaneurysms involving the left common carotid artery. CONCLUSIONS: Numerous options for surgical and endovascular treatment of these lesions are available. Endovascular therapy in patients with common carotid artery pseudoaneurysms offers a reliable and non-invasive management option. It helps in the mitigation of its rupture and thromboembolic complications.
RESUMO
OBJECTIVES: To assess the diagnostic accuracy (ACC) of post-mortem computed tomography (PMCT) for fractures of the isolated larynx-hyoid complex (LHC) in comparison to post-mortem fine preparation (PMFP). METHODS: This monocentric prospective study enclosed 54 LHCs that were extracted during autopsy, fixed in formalin, and underwent a PMCT scan (64-row multidetector CT, helical pitch). Two radiologists independently analyzed the LHC scans for image quality (IQ) and fractures (4-point Likert scales). A specialized forensic preparator dissected the specimens under the stereomicroscope. The PMFP results were standardized documented, and used as the standard of reference for the comparison to PMCT. RESULTS: The PMCT-IQ of 95% of the LHC images was rated as good or excellent. IQ was decreased by decay, incisions during autopsy, and separation of the hyoid from the cartilaginous components in 7, 3, and 12 specimens, respectively. PMFP detected 119 fractures in 34 LHCs (63.0%). PMCT identified 91 fractures in 32 specimens (59.3%). PMFP and PMCT significantly agreed concerning the location (Cohen's κ = 0.762; p < 0.001) and the degree of dislocation (κ = 0.689; p < 0.001) of the fractures. Comparing PMCT to PMFP resulted in a sensitivity of 88.2%, a specificity of 90.0%, and an ACC of 88.9% for the LHC. The ACCs for the hyoid, thyroid, and cricoid were 94.4%, 87.0%, and 81.5%, respectively. PMCT procedure was significantly faster than PMFP (28.9 ± 4.1 min vs. 208.2 ± 32.5 min; p < 0,001). CONCLUSIONS: PMCT can detect distinct injuries of the isolated LHC and may promptly confirm violence against the neck as cause of death. PMFP outmatches PMCT in the detection of decent injuries like tears of the cricoid cartilage. KEY POINTS: ⢠Post-mortem computed tomography is able to assess fractures of the larynx-hyoid complex. ⢠Prospective monocentric in vitro study showed that post-mortem computed tomography of the larynx-hyoid complex is faster than post-mortem fine preparation. ⢠Post-mortem computed tomography can confirm violence against the neck as cause of death.

Background: The use of bicycle helmets in preventing traumatic brain injuries (TBI) is frequently cited but data remain inconclusive. Additionally, the effects of helmets on cervical spine injuries (CSI) are debated.Methods: We performed a retrospective review of all adult patients with bicycle crashes presenting to one level 1 trauma center in Wisconsin from 2010 to 2016. Patients were divided into two groups: helmeted and un-helmeted.Results: In total 287 patients were included; 149 un-helmeted (51.9%) and 138 helmeted (48.9%). Helmeted riders had radiographic evidence of traumatic brain injury in 20.3% of cases compared to 40.3% of un-helmeted (p < 0.001). On average, helmeted riders had a similar injury severity score of 7.80 (standard deviation (SD) = 7.18) compared with 8.25 (SD = 9.98) in the un-helmeted group (p = 0.68). CSI occurred in 16 (10.7%) un-helmeted patients compared with 15 (10.9%) helmeted patients (p = 0.707). Of the un-helmeted group, four patients (2.7%) were found to have a cervical spine fracture compared with 12 (8.7%) helmeted patients (p = 0.037).Conclusion: Helmet use demonstrated a statistically significant advantage in the prevention of traumatic brain injuries. No significant difference was found regarding the incidence of severity of cervical spine injuries. These results do not demonstrate any statistically significant benefit in the prevention of cervical spine injuries with helmet use. In contrast, helmet use was found to convey a significant protective advantage in the prevention of traumatic brain injuries compared to no helmets.

BACKGROUND: There are many high-volume trauma centers in limited resource environments where a thorough clinical examination of patients may contribute to a more economical, accurate, and widely applicable method of determining the proper management of patients with penetrating neck injuries. The purpose of this study was to validate thorough physical examination as a reliable diagnostic tool in these patients. METHODS: We performed an observational retrospective study of a diagnostic accuracy test where we compared clinical findings (symptoms and soft signs on admission of the patient) with the definitive findings according to the gold standard test for each particular situation (selective studies, clinical observation and surgical exploration). The study was conducted at Hospital Occidente Kennedy (HOK) between August 2009 and June 2010. RESULTS: The sample consisted of the clinical records of 207 (n = 207) patients who went to the emergency room for penetrating neck wounds at Hospital Occidente Kennedy (HOK). Of the total sample, 36.2% (n = 75) of patients were considered "asymptomatic" as they didn't present with any soft signs of injury. Vascular soft signs were present in 57% (n = 118) of the patients, soft signs of the airway and the upper gastrointestinal tract were present in 15.9% (n = 33) and 21.3% (n = 44) of the patients respectively. The sensitivity and negative predictive value (NPV) of any soft sign to determine injuries which require surgical repair was 97.4% [CI] [86.5-99.5%] and 98.7% [CI] [92.8-99.8%] respectively, with a range of confidence [CI] of 95%. CONCLUSIONS: Our study's main findings suggest that patients with neck injuries and no vascular, airway, or gastrointestinal soft sign can be safely managed with a conservative approach. It is important to emphasize the value of the clinical examination since there are many contexts in the modern world where a considerable amount of the population is afflicted by neck trauma and treated under conditions where technological resources are limited.

In some rare cases of hanging, the so-called 'hangman's fracture' is observed. This occurs when a fall from height is associated with hanging, e.g. capital executions. We describe the case of an 81-year-old man who committed suicide by jumping off a bridge, with a rope wrapped around his neck. The combination of hanging and falling caused a series of bone fractures to the cervical spine and the hyoid bone, leading to dislocation of the vertebral column and multiple bone fragments, producing peculiar patterns. Computed tomography also identified a transverse full-thickness fracture of the dens, which is a rare event. This case highlights specific injuries associated with the combination of hanging and falling, and underlines the importance of a multidisciplinary approach in terms of radiological examination and complete autopsy.

Isolated thyroid rupture and hematoma are rare following blunt neck injury and can lead to airway compromise and the need for emergency management. We report a 23-year-old male patient who presented with neck swelling and aphonia following a road traffic accident. Contrast-enhanced CT scan showed laceration and hematoma involving left thyroid lobe. The patient underwent left hemithyroidectomy and accomplished complete recovery. A high index of suspicion for thyroid rupture must be maintained when patients presented with voice changes or respiratory distress.
RESUMO
OBJECTIVE: The aims of this study were (1) to provide an overview of craniocervical magnetic resonance imaging (MR) findings following nonfatal strangulation (NFS), (2) to detect the time dependency of the presence of these findings, and (3) to explore the additional value of MR with regard to the forensic interpretation of NFS. METHODOLOGY: All 633 victims of manual strangulation between October 2011 and March 2018 were examined, including the case history and external findings. Following written consent, 114 cases were included in the study. The duration between the event, clinical forensic examination, and MR was noted. Radiologic images were reviewed by a clinical and a forensic radiologist. RESULTS: The case group consisted of 90 women and 24 men with a mean age of 32.5 years. Delimitable external findings were present in 93% (N = 106) of cases. MR yielded a positive finding in 43% of cases (N = 49). There was no significant difference in the mean time interval between examinations between MR-positive and MR-negative cases. Perilaryngeal fluid accumulation was associated with difficulty swallowing and victims put in a chokehold. All cerebral MR were unremarkable, except for one patient with edema of the corpus callosum. CONCLUSIONS: The role of craniocervical MR following NFS is currently limited, particularly with regard to the forensic interpretation of NFS. MR may reveal internal injury in victims who report subjective symptoms of airway compression and in those who were placed in a chokehold. The presence of MR findings is not dependent on immediate examinations following the assault. KEY POINTS: ⢠Magnetic resonance imaging does not currently provide additional value for the estimation of the severity of nonfatal manual strangulation. ⢠Magnetic resonance imaging of the neck may reveal internal injury in cases without external findings, particularly in victims placed in a chokehold and with symptoms of airway compression. ⢠The incidence of carotid artery dissections and laryngeal fractures is low in victims of nonfatal manual strangulation.

BACKGROUND: Cervical spine disorders are frequently associated with temporomandibular disorders (TMDs). Although headache is common in TMD, few studies have considered headache regarding the functional performance of the cervical spine in TMD. OBJECTIVES: To evaluate TMD subjects with and without self-reported headache, assess the active and passive range of motion (ROM) of the upper cervical spine (C1-C2) and performance of the deep cervical flexors, and evaluate the correlation of these outcomes with neck disability and temporomandibular pain. METHODS: In this cross-sectional study, we assessed 57 women (40 with TMDs and 17 without TMDs [controls]). The TMD group was divided into 25 and 15 patients with and without self-reported headache, respectively. We assessed the active and passive upper cervical ROMs using the flexion-rotation test (FRT) and muscle performance using the craniocervical flexion test (CCFT). The neck disability index questionnaire and visual analog scale were used to assess self-reported neck disability and temporomandibular pain, respectively. RESULTS: Compared to controls, all TMD subjects showed reduced cervical mobility on flexion/extension movements, reduced FRT findings and worse performance in CCFT (P < .05 all). Additionally, the CCFT and FRT findings were correlated with temporomandibular pain (r = .4 and .5, respectively) and neck disability (r = .3 and .4, respectively). CONCLUSION: Women with TMDs, regardless of self-reported headaches, showed limited flexion/extension ROM, limited upper cervical spine (C1-C2) mobility and poor deep cervical flexor performance. Neck disability and temporomandibular pain showed a moderate correlation with the functional test findings, that is FRT and CCFT, in subjects with TMDs.

Decapitation is well-documented as an immediately lethal injury that is encountered in medicolegal autopsies. It can be due to an accident, suicide, or homicide. Literature on decapitation reveals that suicide is committed by decapitation using domestic or industrial tools, such as electric saws and drills, and improvised guillotines. Decapitation can also be the result of railway or other bizarre incidents. In this particular case, a man committed suicide by decapitation using a log splitter. This has not been reported earlier. Death investigation, including a medicolegal autopsy and scene visit, was conducted. The decedent, a man in his late forties, had been diagnosed with bipolar disorder approximately five years prior to his death and was being treated for this condition. During the year prior to his death, he had been seeing his physician every two weeks for suicidal ideation. Scene investigation revealed a decapitated male lying beside a jigged and powered log splitter in his yard. The autopsy showed no other injuries or pathological conditions. The cause of death was decapitation and the manner of death was suicide. This is a unique case of decapitation by a log splitter which highlights the importance of scene investigation in order to determine the manner of death.

PURPOSE: To determine the utility of cervical spine MRI in blunt trauma evaluation for instability after a negative non-contrast cervical spine CT. METHODS: A review of medical records identified all adult patients with blunt trauma who underwent CT cervical spine followed by MRI within 48 h over a 33-month period. Utility of subsequent MRI was assessed in terms of findings and impact on outcome. RESULTS: A total of 1,271 patients with blunt cervical spine trauma underwent both cervical spine CT and MRI within 48 h; 1,080 patients were included in the study analysis. Sixty-six percent of patients with a CT cervical spine study had a negative study. Of these, the subsequent cervical spine MRI had positive findings in 20.9%; 92.6% had stable ligamentous or osseous injuries, 6.0% had unstable injuries and 1.3% had potentially unstable injuries. For unstable injury, the NPV for CT was 98.5%. In all 712 patients undergoing both CT and MRI, only 1.5% had unstable injuries, and only 0.42% had significant change in management. CONCLUSIONS: MRI for blunt trauma evaluation remains not infrequent at our institution. MRI may have utility only in certain patients with persistent abnormal neurological examination. KEY POINTS: ⢠MRI has limited utility after negative cervical CT in blunt trauma. ⢠MRI is frequently positive for non-specific soft-tissue injury. ⢠Unstable injury missed on CT is infrequent.

OBJECTIVE: Despite a growing number of injuries, no studies exist to date that quantitatively assess the strangulation risk of amber teething necklaces. The objectives of this study are to determine (a) if these necklaces release with the force required according to the American Society for Testing and Materials (ASTM) Standard Specification for Consumer Product Safety for Mechanical Requirements of Children's Jewelry, and (b) if they release with the mean force required to occlude a young child's airway, as determined in a study designed to inform manufacturing of products to reduce risk of accidental strangulation. METHODS: Fifteen amber teething necklaces were purchased from retailers in Atlantic Canada. Necklaces were tested using the Breakaway Tension Test method reported in ASTM guidelines. Necklaces were tested with a 15 pound weight (industry standard) and with a 1.6 pound weight (mean force required to occlude a child's airway). It was recorded whether the necklace released or remained intact at the end of each trial. RESULTS: Seven of fifteen necklaces did not open with 15 lbs of force. Eight of 10 necklaces tested did not open with 1.6 lbs of force. CONCLUSION: Almost 50% of our sample failed to open with 15 pounds of force, which is the force used in the ASTM standard for children's jewelry. Eighty per cent of our sample failed to open with 1.6 pounds of force, which was the mean force to occlude a young child's airway in a published study. These necklaces pose a strangulation risk to young children if they were to become caught.
RESUMO
- A 45-year-old male patient was admitted to the emergency unit due to posterior stab wound of the neck. The knife was directed diagonally from the left to the right side of the neck in the dorsoventral axis. The patient was fully conscious upon admission with pain and paresthesia along the upper right extremity. The patient underwent computed tomography (CT) and CT angiography scan of the neck, which revealed the knife blade piercing the left sided neck muscles and through the intervertebral ligaments of the C IV/C V in direction to the contralateral internal carotid artery, vertebral artery and the C5 nerve root. The patient underwent an urgent surgery according to the radiographs. Electromyography was performed during the early postoperative care and revealed an acute lesion of the right-sided C5 nerve root. Postoperative follow-up magnetic resonance imaging revealed intact brachial plexus bundles at the site of injury. Symptoms of reduced muscle strength and limited range of motion of the upper right extremity prevailed. Penetrating neck injuries represent a rare entity of all trauma injuries. Meticulous preoperative radiographs revealed close proximity of the knife blade tip to the right-sided vertebral artery and common carotid artery. Limited abduction at the right shoulder during postoperative period correlated to the C5 nerve root injury.

BACKGROUND: Blunt injuries to the cervical trachea remain rare but present unique and challenging clinical scenarios for prehospital providers. These injuries depend on prehospital providers either definitively securing the injured airway or bridging the patient to a treatment facility that can mobilize the necessary resources. CASE SUMMARY: The case presented here involves a clothesline injury to a pediatric patient that resulted in complete tracheal transection and partial esophageal transection. Ground and air prehospital providers utilized a stepwise approach to this airway injury and achieved a favorable outcome. The patient was serendipitously intubated through a blind nasal approach that entered the proximal esophagus, exited through the tear and entered the distal trachea. DISCUSSION: There is a paucity of literature describing the successful management of these devastating injuries. While some authors have advocated for early flexible fiberoptic intubation or proceeding directly to tracheostomy, these techniques are not available in the prehospital environment. This case also highlights the inherent issues with proceeding to cricothyroidotomy in patients with tracheal trauma and should give all providers pause before considering this management technique. CONCLUSION: Ultimately, a systematic approach to all airways will ensure that prehospital providers are best prepared for even the most challenging scenarios.

Necrotizing fasciitis (NF) is a severe bacterial infection with rapid and aggressive progression. The infection generally affects individuals with comorbid conditions that lead to immunologic and microvascular deficiencies. It is characterized by necrosis of tissues, mainly in the extremities, trunk, and perineum, and is rarely found in the head and neck. This case report describes the course of NF in a 55-year-old man, highlighting diagnosis, surgical treatment, drug therapy, and supportive measures. The patient, who had chronic alcoholism, systemic arterial hypertension, a smoking habit, and decompensated diabetes (glucose level of 490 mg/dL), was admitted to the hospital with a volume increase in the cervical and thoracic areas with a duration of about 7 days. He presented with fever, dyspnea, and inflammatory signs bilaterally in the submandibular, submental, and superior thoracic regions as well as severe trismus. The patient underwent a surgical procedure to drain the infectious process and to place drains. The patient developed cutaneous necrosis in the cervical and superior thoracic regions, diagnosed as NF. Surgical debridement of all affected tissue was performed. After resolution of the infection, the patient underwent skin grafting with a satisfactory outcome.
