RÉSUMÉ

Reconstruction of burns in the head and neck region is challenging. This is because it must achieve both functional reconstruction and esthetic reconstruction. Local flaps are best for minor defects, particularly in the case of deep burns, because they bear the correct texture and color. However, for large deep burn wounds, simple grafting or small local flaps will not produce satisfactory results. It is also crucial to assess the extent and depth of reconstruction that is needed throughout the face-neck-anterior chest region, and to make the choice between techniques such as Z-plasty, skin grafting, super-thin flaps, and free flaps.

RÉSUMÉ

Penetrating neck trauma is becoming a more frequently encountered presentation in UK emergency departments. Although largely attributable to violent crime, other aetiologies are on the rise. This study aimed to review changes in the pattern of penetrating neck injury (PNI) over a five-year period at our level 1 major trauma centre. Data were retrospectively collected on all patients presenting to the emergency department with PNIs between 2016 and 2021. The number of these injuries doubled between 2016 and 2021, accounting for 11% of all penetrating trauma in 2021. The majority of patients were male (87%). Violence remained the predominant aetiology but numbers of self-harm-related PNIs trebled between 2018 and 2021. PNIs are on the rise. These injuries remain complex to manage and require a multidisciplinary approach. Tackling violent crime remains essential in combating PNIs, but focus must also be placed on identifying and supporting individuals most at risk of deliberate self-harm from a deterioration in mental health.

RÉSUMÉ

The pattern of neck injuries sustained in fatal cases of external compression to the neck is recorded during Post Mortem Examinations (PME), to assist in the interpretation of the circumstances that led to death. In this study, the PMEs performed for 298 cases of hanging and strangulation occurring between 2016 and 2020 in Ireland were retrospectively reviewed for the purpose of recording and collating the external and internal neck injuries observed during each PME, as well as the toxicology results for each decedent. Statistical analysis was performed to investigate potential novel associations between anthropometric variables pertaining to the decedents and the PME findings in cases of hanging and strangulation, serving to add further data to the existing body of research in this area and to assist in the resolution of future cases of hanging or strangulation where there are conflicting findings. In completing statistical analysis, it was found that there was no discernible association between the occurrences of cartilaginous neck fractures (CNFs) with increasing ligature width. Positive associations between increasing weight and BMI of the decedents were identified, and a significantly positive association between the increasing height of the decedent and the incidence of CNFs were identified. Analysis of the toxicology demonstrated that antipsychotics were implicated most frequently in cases of incomplete and complete hanging associated with CNFs and that opioids were implicated most frequently in cases of manual and ligature strangulation associated with CNFs. OBJECTIVE: To record the pattern of neck injuries sustained in retrospective cases of hanging and manual/ligature strangulation and to collate these findings so as to provide scientific evidence to support the interpretation of the findings in future cases of suicidal hanging and homicidal manual/ligature strangulation for the purpose of medicolegal investigation. To analyse the associations between the occurrence of neck fractures and anthropometric variables pertaining to the victims in cases of complete hanging. STUDY DESIGN: The reports of 298 Post Mortem Examinations (PMEs) performed for cases of hanging and manual/homicidal ligature strangulation between 2016 and 2020 in Ireland were retrospectively reviewed. Pseudoanonymised data sets were recorded for each report, which included the following parameters: neck injuries (soft tissue and cartilaginous), weight, height, BMI and ligature width, toxicology, noose position, ligature material, tongue protrusion, sex and age. Permission for the use of this data was sought from the pathologists and coroners involved in these cases. The data was analysed according to descriptive statistical methods and logistic regression analysis. RESULTS: Logistic regression analysis was undertaken to examine the associations between unit increases in ligature width and increases in a set of physical characteristics of the decedents (weight, BMI and height) with the occurrence of CNFs. Increasing ligature width was not found to increase the likelihood of a CNF occurring, where the Odds Ratio (OR) for this event occurring was 0.9596. Unit increases in body weight and BMI were found to increase the likelihood of the occurrence of a CNF with ORs of 1.0166 and 1.0607 respectively. Increasing height of the decedent yielded an OR = 4.64, demonstrating that CNFs are significantly more likely to occur with increasing height (CI 95 %: 0.2915, 73.9559). CONCLUSIONS: According to the statistical analysis performed for this study, increasing weight, height and BMI are parameters of the decedents which increase the likelihood of the occurrence of CNFs in cases of complete hanging.

RÉSUMÉ

Initial experiences with magnetic resonance imaging (MRI) of living strangulation victims demonstrated additional findings of internal injuries compared to the standard clinical forensic examination. However, existing studies on the use of MRI for this purpose mostly focused on the first 48 h after the incident. The aims of this study were (a) to evaluate the longitudinal visibility of MRI findings after violence against the neck by performing two MRI examinations within 12 days and a minimum of four days between both MRI scans and (b) to assess which MRI sequences were most helpful for the detection of injuries. Twenty strangulation victims participated in this study and underwent one (n = 8) or two (n = 12) MRI scans. The first MRI examination was conducted during the first five days, the second five to 12 days after the incident. Two blinded radiologists assessed the MRI data and looked for lesions in the structures of the neck. In total, 140 findings were reported in the 32 MRI examinations. Most of the findings were detected in the thyroid and the muscles of the neck. T2-weighted SPACE with fat suppression, T1-weighted TSE and T1-weighted MPRAGE were rated as the most helpful MRI sequences. Subjects who showed findings in the initial scan also demonstrated comparable results in the second scan, which was performed on average 8.4 days after the incident. Our results show that even up to 12 days after the incident, the criminal proceeding of strangulation cases may greatly profit from the information provided by an MRI examination of the neck in addition to the standard clinical forensic examination.

RÉSUMÉ

INTRODUCTION: Burns to the face and neck are a source of considerable distress and a challenge to manage with dressings. Further, these often superficial injuries pose a risk of scarring and altered pigmentation. Silicone gels have emerged as a potential solution to the challenges of conservative management for face and neck burn injuries. The aims of this study were to explore the effect of topical silicone compared to routine treatment of conservatively managed burns to the face and neck. METHODS: This single-blind, randomised, controlled trial compared topical silicone film-forming dressing to standard of care for superficial partial thickness burns to the face and neck. Time to healing was the primary outcome and secondary outcomes included: 1) scar assessments (modified Vancouver Scar Scale, Dermalab Combo and Patient and Observer Scar Assessment Scale) at six weeks and three months; and 2) pain intensity scale at wound review appointments. RESULTS: Of the 55 participants in the face/neck study, 34 were male and 21 were female. Median age was 36 years (range from 25 to 47 years). The median time to healing for the silicone group was 9 days (CI 7.6 -10.4) and the control group was 7 days (CI 5.3- 8.7), p = 0.056. Analysis demonstrated significantly reduced pigmentation at six weeks in mVSS scores for the silicone group (Md = 0, IQR = 0) compared to the control group (Md = 0, IQR = 0 - 3), p = 0.043. We found no evidence of differences in reported pain between the groups (Silicone - Md = 1.15, IQR 0.3 - 4.5 vs control group - Md = 1.5, IQR 0.6 - 3.8, z = -0.63, p = 0.53). No other differences were observed, and no adverse events were associated with the topical silicone in the study whereas an infection and a reaction were experienced in the control group. CONCLUSION: Film-forming silicone gel had comparable effects to standard of care emollient on wound healing of superficial partial thickness burns of the face and neck. Silicone treated wounds were associated with a significant improvement in scar pigmentation outcome at six weeks post-burn.

RÉSUMÉ

The aim of this study was to evaluate the incidence and patterns of maxillofacial fractures and the demographic characteristics of associated head and neck injuries. This single-center retrospective cohort study was conducted at the Department of Oral and Maxillofacial Surgery of King Abdullah University Hospital (KAUH) in Irbid, northern Jordan. The data was obtained from the electronic clinical records of all patients in whom maxillofacial fractures and associated head and neck injuries were confirmed. During the five-year period captured by this retrospective study, 481 patients with 1026 maxillofacial fractures (equivalent to 2.13 fractures per patient) were treated. The sample comprised of 369 (76.7%) males and 112 (23.3%) females, resulting in a male/female ratio of 3.3:1. Majority of the patients were in the 21-30 age group and RTA was the most common cause of maxillofacial fractures, accounting for 299 (62.1%) of the analyzed cases. In 316 cases, maxillary fractures were accompanied by associated injuries, 132 (41.77%) of which were intracranial lesions, 80 (25.32%) were skull fractures, and 59 (18.67%) were cervical spine injuries. Based on the obtained data, it can be concluded that the high occurrence of RTA emphasizes the significance of adhering to traffic laws and regulations, as individuals who have suffered serious head and neck injuries as a result of maxillofacial trauma may experience potentially fatal consequences. Thus, management for patients with maxillofacial fractures and concomitant traumas should be multidisciplinary and coordinated.

RÉSUMÉ

Aim: AAnalysis of the choice of suicide method by gender and age of the deceased. Material and methods: The study presented here was based on a retrospective analysis of autopsy reports from the years 2001-2010 in the Department of Forensic Medicine of the Jagiellonian University Collegium Medicum in Kraków. The basis of the research work conducted was the collection and extensive analysis of cases of suicide deaths. Subsequently, a preference analysis of the choice of suicide method was conducted, taking into account the age and gender of the deceased. The statistical analysis performed used logistic regression in Excel's XLSTAT as an analysis tool. Results: A total of 2,073 suicide cases were collected from the time frame under discussion. The predominant method of suicide was hanging (1524 cases, 1329 men and 195 women), the second most common method was jumping from the roof or window of a high floor of a building (jumping from heights; 171 cases, 100 men, 71 women). A statistically significant correlation of suicide method with gender was found for: hanging [odds ratio (OR) male (M) vs. female (F) = 3. 4; confidence interval (CI) = 2.7-4.3; p0.001]; drowning [OR: M/F =4.1; CI = 2.6-6.4; p0.001]; jumping from heights [OR: M/F=4.1; CI=2.9-5.7; p0.001] and poisoning [OR: M/F=3.2; CI = 2.1-4.9]. Suicide with the use of firearms occurred exclusively in the case of men (40 cases). The age of the victims correlated with the method of committing suicide by jumping from heights [0R=0.98; CI=0.97-0.99; p0.001] and rail suicide [OR=0.98; CI=0.96-0.99; p0.001]. Conclusions: The study revealed that both age and gender have a significant impact on the choice of suicide method. According to available epidemiological data and the authors' predictions, a predominance of male over female sex was observed in the case of hanging, while jumping from heights was relatively more often chosen by women. The elderly were less likely to choose jumping from heights and rail suicide.

RÉSUMÉ

Foreign body ingestion is a common clinical occurrence worldwide, with high morbidity in the pediatric population and in adult patients with intentional attempts. Coins and button battery ingestions are more common among children. Bone impaction and swallowed dentures are usually seen in older adults. While most ingested foreign bodies pass through the gastrointestinal tract spontaneously with no complications, some require endoscopic and/or surgical intervention. Complications such as pharyngoesophageal ulceration, perforation, stricture, and deep neck infection can develop without timely diagnosis and management. The purpose of this article is to familiarize radiologists with the imaging approach to assess for characteristics and impacted locations of ingested foreign bodies in the neck.

RÉSUMÉ

OBJECTIVE: To evaluate the possible etiological factors of spontaneous pneumomediastinum and to describe a case that was unusual in its etiology: a thyroid cartilage fracture as a result of sneezing. MATERIAL AND METHODS: Six patients (four male, two female, aged 16-82 years) were hospitalized with spontaneous pneumomediastinum diagnosed with a chest X-ray in five patients and 100% with computed tomography. Treatment was symptomatic. RESULTS: The commonest symptoms (cough, shortness of breath, hoarseness) were in four patients. Spontaneous pneumomediastinum developed in three cases as a result of bronchospasm during an attack of bronchial asthma, in one patient after exercise, in one after fibrogastroscopy, in one after sneezing. We report a 30-year-old man who presenting subcutaneous emphysema on the neck, hoarseness, pain when swallowing, hemoptysis developed after sneezing. His computed tomography revealed a pneumomediastinum due to fistula of the fracture of the thyroid cartilage following sneezing while simultaneously obstructing both nostrils. At laryngoscopy, there was a linear hematoma in the resolution stage on the anterior wall of the larynx. He was treated conservatively and recovered rapidly. There are no previous published reports of spontaneous pneumomediastinum following fracture of the thyroid cartilage. CONCLUSION: Fracture of the thyroid cartilage as a result of a sharp rapid increase in airway pressure during a sneeze with blocked nasal passages can be one of the rare causes of spontaneous pneumomediastinum. Avoid closing both nostrils at the same time when sneezing.

RÉSUMÉ

As medicolegal consultant, we often encounter cases of fall from height related deaths which are invariably subjected to medicolegal autopsy and the numbers are gradually increasing day by day. During the study period of three years data were collected by using a pre-tested structured proforma, police inquest reports, hospital records and thorough medicolegal autopsy done at Chittagong Medical College Mortuary. This retrospective autopsy based study revealed 175 cases of fall from height casualties out of the total 2850 autopsies. We observed that the age group of 41-50 years i.e. 55 cases were mostly affected followed by 31-40 years i.e. in 40 cases. Males (144) were the main sufferers than the females (31). Maximum victims were construction workers 57 cases (32.57%) followed by 45 factory workers (25.71%). Construction sites were the main place of fall i.e. in 57 cases (32.57%) followed by working places 46 cases (26.28%). Most of the victims had head-neck injuries i.e. in 143 cases (81.71%) followed by thoracic injury 82 cases (46.85%). Multiple injuries i.e. in 92 cases (52.57%) were the main cause of death followed by head-neck injuries in 79 cases (45.14%). These casualties are definitely preventable by adopting safety measures and by educating the workers in the factories and construction sites.

RÉSUMÉ

BACKGROUND: A large proportion of United States (U.S.) youth play basketball, baseball, softball, or T-ball. Each of the activities poses a documented risk of craniofacial and neck injuries. However, few studies have assessed the national prevalence of pediatric craniofacial and neck injuries in this population, particularly following the COVID-19 pandemic. METHODS: The National Electronic Injury Surveillance System (NEISS) dataset was used to identify pediatric craniofacial and neck injuries associated with basketball, baseball, softball, or T-ball from 2003-2022 in a cross-sectional study. The annual number of injuries before and after the onset of the COVID-19 pandemic with 95% confidence intervals were calculated. Interrupted time series analysis (ITSA) was used to estimate the pandemic's impact on the monthly number of injuries incurred nationally. RESULTS: Both overall and stratified by sport involvement, the annual number and rate of injuries identified in NEISS decreased significantly after the COVID-19 pandemic. ITSA demonstrated that the monthly number of injuries decreased -4094.4 (95% CI = -5100, -3088.7) immediately after the beginning of the pandemic. The number of injuries began increasing towards pre-pandemic levels at a rate of 110.6 (95% CI = 64, 157.2) injuries per month after the initial plunge. CONCLUSION: Prior to the-pandemic, there was a steady decline in craniofacial and neck injuries due to basketball, baseball, softball and T-ball among children, aged <18 years. The shutdown during the initial months of the COVID-19 pandemic resulted in a precipitous drop in such injuries. Current rates are approaching pre-pandemic levels and may exceed them. Continued efforts are needed to keep the pre-pandemic progress.

RÉSUMÉ

STUDY DESIGN: Cross-Sectional Study. OBJECTIVES: To investigate the changes in the characteristics of cervical spinal cord injuries (CSCI) before and after the coronavirus disease 2019 (COVID-19) pandemic among patients transported to our hospital in Japan. SETTING: Hospital with an emergency center in Chiba, Japan. METHODS: Patients eligible for the study were those transported within 24 h of injury and diagnosed with cervical spinal cord injury between January 2018 and December 2021 at our hospital. Medical records were retrospectively examined to investigate the number and characteristics of patients with CSCI. The clinical variables of patients with CSCI were compared according to the time of admission as related to the COVID-19 pandemic: 2018-19 (before) or 2020-21 (after). RESULTS: The total number of patients with CSCI from 2018 to 2021 was 108, with 57 before the COVID-19 pandemic and 51 after the COVID-19 pandemic. The number of severe cases with an injury severity score (ISS) of >16 decreased after COVID-19 (p < 0.05). Falls on level surfaces were the most common cause of injury both before and after COVID-19. Although the ranking of traffic accidents decreased after COVID-19, among those, the number of bicycle injuries tended to increase. CONCLUSIONS: The number of serious cases with an ISS > 16 decreased, presumably because of the decline in high-energy trauma due to the background decrease in the number of traffic accidents.

RÉSUMÉ

PURPOSE: With the increasing level of automation in automobiles, the advent of autonomous vehicles has reduced the tendency of drivers and passengers to focus on the task of driving. The increasing automation in automobiles reduced the drivers' and passengers' focus on driving, which allowed occupants to choose a more relaxed and comfortable sitting position. Meanwhile, the occupant's sitting position went from a frontal, upright position to a more relaxed and reclined one, which resulted in the existing restraint systems cannot to keep occupants safe and secure. This study aimed to determine the effects of different reclining states on occupants' lumbar and neck injuries. METHODS: This is an original research on the field of automotive safety engineering. Occupants in different initial sitting positions (25°, 35°, 45°, and 55°) were adapted to changes in seat back angle and restraint systems and placed in the same frontal impact environment. Neck injury indexes, lumbar axial compression force and acceleration, as well as occupant dynamic response during the impact, were compared in different sitting positions. The injury response and kinematic characteristics of occupants in different reclining positions were analyzed by the control variable method. RESULTS: As the sitting angle increased, the occupant's head acceleration decreased, and the forward-lean angle decreased. Occupants in the standard sitting position had the greatest neck injury, with an Nij of 0.95, and were susceptible to abbreviated injury scale 2+ cervical medullary injuries. As the seatback angle increased, the geometric position of the lumbar spine tended to be horizontal, and the impact load transmitted greater forces to the lumbar spine. The occupant's lumbar injury was greatest in the lying position, with a peak axial compression force on the lumbar region of 5.5 KN, which was 2.3 KN greater than in the standard sitting position. CONCLUSION: The study of occupant lumbar and neck injuries based on different recline states can provide a theoretical basis for optimizing lumbar evaluation indexes, which is conducive to the understanding of the lumbar injury mechanism and the comprehensive consideration of occupant safety protection.

RÉSUMÉ

Hanging is one of the most common suicide methods worldwide. Neck injuries that occur upon such neck compression - fractures of the thyrohyoid complex and cervical spine, occupy forensic pathologists for a long time. However, research failed to identify particular patterns of these injuries corresponding to the force distribution a ligature applies to the neck: the issue of reconstructing the knot in a noose position persists. So far, machine learning (ML) models were not utilized to classify knot positions and reconstruct this event. We conducted a single-institutional, retrospective study on 1235 autopsy cases of suicidal hanging, developed several ML models, and assessed their classification performance in a stepwise manner to discriminate between: 1. typical ('posterior) and atypical ('anterior' and 'lateral') hangings, 2. anterior and lateral hangings, and 3. left and right lateral hangings. The variable coding was based on the presence/absence of fractures of greater hyoid bone horns (GHH), superior thyroid cartilage horns (STH), and cervical spine. Subject age was considered. The models' parameters were optimized by the Genetic Algorithm. The accuracy of ML models in the first step was very modest (c. 60%) but increased subsequently: Multilayer Perceptron - Artificial Neural Network and k-Nearest Neighbors performed excellently discriminating between left and right lateral hangings (accuracy 91.8% and 90.6%, respectively). The latter is of great importance for clarifying probable hanging fracture biomechanics. Alongside the conventional inferential statistical analysis we performed, our results further indicate the association of the knot position with ipsilateral GHH and contralateral STH fractures in lateral hangings. Moreover, odds for unilateral GHH fracture, simultaneous GHH and STH fractures, and cervical spine fracture were significantly higher in atypical ('anterior' and 'lateral') hangings, compared to typical ('posterior') hangings.

RÉSUMÉ

PURPOSE: Penetrating neck injuries (PNIs), defined as deep to the platysma, can result in significant morbidity and mortality. Management has evolved from a zone-based approach to a 'no zone' algorithm, resulting in reduced non-therapeutic neck exploration rates. The aim of this study was to examine PNIs and its management trends in an Australian tertiary trauma centre, to determine if a 'no zone' approach could be safely implemented in this population, as has been demonstrated internationally. METHODOLOGY: This was a retrospective observational study at a level 1 adult Australian tertiary trauma centre using prospectively collated data from January 2008 to December 2018. Observed data included age, gender, mechanism of injury, computed tomography angiography (CT-A) use and operative intervention. Patients were examined based on zone of injury and presenting signs - 'hard', 'soft' or 'asymptomatic'. Major outcomes were CT-A usage, positive CT-A correlation with therapeutic neck explorations and negative neck exploration rates. RESULTS: This study identified 238 PNI patients, with 204 selected for review. Most injuries occurred in zone 2 (71.6%), with soft signs accounting for 53.4% of cases. Over 10 years, CT-A utilization increased from 55% to 94.1%, with positive CT-As being more likely to yield therapeutic neck explorations. There was a general decreased trend in operative intervention but without a clear reduction in non-therapeutic neck explorations. CONCLUSION: Our data suggests similarities with results from around the world, demonstrating that the 'no zone' approach should be considered when managing PNIs, but with clinician discretion in individual cases.

RÉSUMÉ

BACKGROUND: Vertebral artery injury is a rare condition in trauma settings. In the advanced stages, it causes death. CASE: A 31-year-old Sundanese woman with cerebral edema, C2-C3 anterolisthesis, and Le Fort III fracture after a motorcycle accident was admitted to the emergency room. On the fifth day, she underwent arch bar maxillomandibular application and debridement in general anesthesia with a hyperextended neck position. Unfortunately, her rigid neck collar was removed in the high care unit before surgery. Her condition deteriorated 72 hours after surgery. Digital subtraction angiography revealed a grade 5 bilateral vertebral artery injury due to cervical spine displacement and a grade 4 left internal carotid artery injury with a carotid cavernous fistula (CCF). The patient was declared brain death as not improved cerebral perfusion after CCF coiling. CONCLUSIONS: Brain death due to cerebral hypoperfusion following cerebrovascular injury in this patient could be prevented by early endovascular intervention and cervical immobilisation.

RÉSUMÉ

OBJECTIVE: To describe the epidemiology and patterns of gymnastics-related Head & Neck trauma injuries using the NEISS database from 2001 to 2020. STUDY DESIGN AND SETTING: Cross-sectional analysis of a national database. METHODS: Gymnastics-related ED visits between 2001 and 2020 were queried from the NEISS database. Bivariate chi-squared analyses were used to compare injury demographics, location, type, and disposition. Fracture location was identified using the narrative description of each case and were divided into subtypes for further analysis. RESULTS: 1455 gymnastics-related head and neck traumatic injuries were identified. The majority were in females (65.8%). The most common presenting age group was pediatric (≤18 years) (92.7%), and the largest racial group was Caucasian (51.5%). Of all location subtypes, facial injuries were the most common presenting injury type overall (45.2%). Regarding injury types, lacerations were most common (36.8%), followed by dental injury (30.7%) and fractures (21.2%). The most common location of head and neck fractures was the nose (45.8%), followed by cervical spine (16.7%) and orbit (13.3%). The majority (95.7%) of gymnastics-related head and neck traumatic injuries presenting to the ED were treated and discharged. CONCLUSION: This study characterizes gymnastics-related head and neck injuries which is a topic that is under-studied. The findings from this study are helpful for gymnasts and those who care for them including providers, coaches and guardians, and this data may help inform future guidelines for treatment and injury prevention.

RÉSUMÉ

Background and Objectives: In the context of complex aerodigestive cervical traumas, the prognosis and outcome heavily depend on risk factors, particularly injuries to the larynx, trachea, major digestive tissues, cervical vertebrae, and vascular structures. With the increasing prevalence of trauma as a public health concern, there is a pressing need for epidemiological research and the implementation of preventative measures. The purpose of this research is to establish the profile of the predictable impact factors that determine the prognosis of patients with complex cervical trauma. Methods and Methods: The study group consisted of 106 patients with complex cervical trauma pathology developed by various mechanisms such as car accidents, home-related accidents, aggression, gunshot wounds, and self-inflicted attempts, resulting in hospitalization in the E.N.T. Clinic at "St. Spiridon" Iași Hospital, from 2012 to 2016; medical records were the source of the collected data. Results: Hemodynamic instability upon admission associated with age, muscle and laryngeal injuries, and anemia were identified as negative prognostic factors. Additionally, the utilization of imaging-based paraclinical investigations for diagnosing traumatic lesions emerged as a positive prognostic factor in managing this pathology. The management of penetrating cervical trauma remains a subject of debate, with some advocating for surgical exploration beyond the platysma layer in all cases, while others argue for a more selective conservative approach due to a high rate of negative explorations. Conclusions: The statistical evaluation of epidemiological, clinical, lesion, paraclinical, and therapeutic parameters is needed to establish predictable risk factors in the prognosis of complex aerodigestive cervical trauma.
