The association between head injury and facial fracture treatment: an observational study of hospitalized bicyclists from a level 1 trauma centre

PURPOSE

To compare the types of facial fractures and their treatment in bicyclists admitted to a level 1 trauma centre with major and minor-moderate head injury.

METHODS

Retrospective analysis of data from bicycle-related injuries in the period 2005-2016 extracted from the Oslo University Hospital trauma registry.

RESULTS

A total of 967 bicyclists with head injuries classified according to the Abbreviated Injury Scale (AIS) were included. The group suffering minor-moderate head injury (AIS Head 1-2) included 518 bicyclists, while 449 bicyclists had major head injury (AIS Head 3-6). The mean patient age was 40.2 years (range 3-91 years) and 701 patients (72%) were men. A total of 521 facial fractures were registered in 262 patients (on average 2 facial fractures per bicyclist). Bicyclists with major head injury exhibited increased odds for facial fractures compared to bicyclists with minor-moderate head injury (sex and age adjusted odds ratio (OR) 2.75, 95% confidence interval (CI) 2.03-3.72, p < 0.001. More specifically, there was increased odds for all midface fractures, but no difference for mandible fractures. There was also increased odds for orbital reconstruction in cyclist with major head injury compared to bicyclist with minor-moderate head injury (adjusted OR 3.34, 95% CI 1.30-8.60, p = 0.012).

CONCLUSION

Bicyclists with more severe head injuries had increased odds for midface fractures and surgical correction of orbital fractures. During trauma triage, the head and the face should be considered as one unit.

A woman in her forties with ear pain

Background

A woman in her forties developed intermittent pain in her ear and pharynx which worsened when talking and swallowing. Multidisciplinary approach confirmed a rare diagnosis.

Case presentation

The patient reported left-sided ear fullness, followed by otalgia and burning pain in the palate. Numbness in the palate and nasal cavity, and soreness upon palpation of the external ear canal were noted upon examination. Magnetic resonance imaging (MRI) with contrast showed a vessel located in close proximity to the glossopharyngeal nerve on the left side. A diagnosis of glossopharyngeal neuralgia was made, and the patient was treated with antiepileptic medications without substantial effect. Microvascular decompression of the glossopharyngeal nerve was therefore performed. A large vein located along the glossopharyngeal nerve was separated and fixated away from the nerve. The patient reported pain alleviation after the operation, which has continued to improve on follow-ups.

Interpretation

Glossopharyngeal neuralgia is a rare condition characterised by intermittent, unilateral pain in the base of the tongue, oropharynx, and/or angle of the mandible which radiates to the ipsilateral ear. The condition should be treated medically, but open surgical treatment should be considered in refractory cases. Early diagnosis and treatment are essential.

Cost Analysis of Open Surgical Bedside Tracheostomy in Intensive Care Unit Patients

OBJECTIVES

Open surgical tracheostomy (OST) is a common procedure performed on intensive care unit (ICU) patients. The procedure can be performed bedside in the ICU (bedside open surgical tracheostomy, BeOST) or in the operating room (operating room open surgical tracheostomy, OROST), with comparable safety and long-term complication rates. We aimed to perform a cost analysis and evaluate the use of human resources and the total time used for both BeOSTs and OROSTs.

METHODS

All OSTs performed in 2017 at 5 different ICUs at Oslo University Hospital Ullevål were retrospectively evaluated. The salaries of the personnel involved in the 2 procedures were obtained from the hospital's finance department. The time taken and the number of procedures performed were extracted from annual reports and from the electronic patient record system, and the annual expenditures were calculated.

RESULTS

Altogether, 142 OSTs were performed, of which 122 (86%) and 20 (14%) were BeOSTs and OROSTs, respectively. A BeOST cost 343 EUR (95% CI: 241.4-444.6) less than an OROST. Bedside open surgical tracheostomies resulted in an annual cost efficiency of 41.818 EUR. In addition, BeOSTs freed 279 hours of operating room occupancy during the study year. Choosing BeOST instead of OROST made 1 nurse, 2 surgical nurses, and 1 anesthetic nurse redundant.

CONCLUSION

Bedside open surgical tracheostomy appears to be cost-, time-, and resource-effective than OROST. In the absence of contraindications, BeOSTs should be performed in ICU patients whenever possible.

Anatomical distribution of mandibular fractures from severe bicycling accidents: A 12-year experience from a Norwegian level 1 trauma center

Background/Aim

The mandible makes up a substantial part of the lower face, and is susceptible to injury. Even in helmeted cyclists, accidents may lead to fractures of the mandible because conventional helmets provide little protection to the lower part of the face. In addition, some studies indicate that helmets may lead to an increased risk of mandibular fractures. Thus, the aim of this study was to examine the anatomic distribution of mandibular fractures in injured cyclists and to assess if helmet use influenced the fracture locations.

Material and Methods

Data from a Norwegian Level 1 trauma center were collected in the Oslo University Hospital Trauma Registry over a 12‐year period. Of 1543 injured cyclists, the electronic patient charts of 62 cyclists with fractures of the mandible were retrospectively evaluated in detail. Demographic data, helmet use, and fracture type were assessed.

Results

Sixty‐two patients (4%) had fractures of the mandible, and women had an increased risk (OR 2.49, 95% CI 1.49–4.16, p < .001). The most common fracture site was the mandibular body, followed by the condyle. Isolated mandibular fractures occurred in 45% of the patients and 55% had other concomitant facial fractures. There were 42% of the patients with fractures in multiple sites of the mandible, and 42% had a concomitant dentoalveolar injury. Half of the cyclists were wearing a helmet at the time of the accident and 39% were not. There was no significant difference in fracture distribution between the helmeted and non‐helmeted groups.

Conclusions

Fracture of the mandibular body was the most prevalent mandibular fracture type following bicycle accidents. Women had an increased risk of mandibular fractures compared with men, whereas helmet wearing did not affect the anatomical fracture site.

A case of septic arthritis of the temporomandibular joint with necrotic peri-articular infection and Lemierre's syndrome: an unusual presentation

BACKGROUND

Septic arthritis of the temporomandibular joint (TMJ) is rare. It usually causes isolated, locoregional symptoms related to the infected intra-articular space but may also cause fever and malaise.

CASE REPORT

We present a case of a 72-year-old male with septic arthritis of the TMJ complicated by extensive peri-articular necrosis, septic shock, cerebral abscess, Lemierre's syndrome, and a pathological fracture of the mandibular condyle.

CONCLUSION

Case reports describing such a severe course of the disease are few. Moreover, this is the first report of septic arthritis of the TMJ to cause Lemierre's syndrome.

Dentoalveolar injuries, bicycling accidents and helmet use in patients referred to a Norwegian Trauma Centre: A 12-year prospective study

BACKGROUND/AIM

Despite its many benefits, bicycling carries the risk of accidents. Although numerous studies have reported the effect of helmet use on traumatic brain injury, it remains unclear if, and to what extent, helmet use reduces the risk of facial injuries. This is particularly true in regard to injuries of the lower face. In addition, there is limited evidence of the effect of helmet use on dentoalveolar injuries. Thus, the aim of this study was to determine the frequency and distribution of dentoalveolar injuries in bicycling accidents and to explore the influence of helmet use.

MATERIAL AND METHODS

A total of 1543 bicyclists were included from the trauma registry of a Norwegian tertiary trauma center over a 12-year period. Data were collected prospectively, including patient characteristics, type of injury, and helmet use. The prevalence of dentoalveolar injuries was assessed in conjunction with helmet use and facial fractures.

RESULTS

Twenty-five percent of the patients had maxillofacial injuries, and 18% of those with facial fractures exhibited concomitant dentoalveolar injuries. The most common type of dentoalveolar injury was tooth fracture (39%). The most frequent location of facial fractures with combined dentoalveolar injuries was the maxilla, which had fractured in 32 patients. Women had a higher risk of sustaining dentoalveolar injuries compared to men (odds ratio 1.50, 95% confidence interval 1.02-2.22). There were 1257 patients (81%) who had reliable registration of helmet use; 54% of these wore a helmet, while 46% did not. Helmet users had an increased risk of dentoalveolar injuries compared to non-helmeted bicyclists (adjusted odds ratio 1.54, 95% confidence interval 1.02-2.31).

CONCLUSIONS

Dentoalveolar injuries are fairly common in trauma patients admitted to a trauma center following bicycling accidents. Bicycling helmets are associated with an increased risk of dentoalveolar injuries.
