The Utility of CTA in Pediatric Oropharyngeal Trauma: A Systematic Review and Meta-Analysis

OBJECTIVE(S)

To analyze the utility of computed tomography angiography (CTA) in identifying internal carotid artery (ICA) injury and reducing cerebrovascular accident (CVA) incidence in children presenting with normal neurologic exams after oropharyngeal trauma (OT).

DATA SOURCES

PubMed, Scopus, CINAHL, and Cochrane.

REVIEW METHODS

A systematic review and meta-analysis were performed following PRISMA guidelines. Of 1,185 studies screened, 95 studies of pediatric OT met inclusion criteria. Meta-analysis of proportions was performed.

RESULTS

A total of 1224 children with OT were analyzed. Excluding case reports, the weighted proportion of a CVA after OT was 0.31% (95% CI 0.06-0.93). If a child presented without neurologic deficits, 0.30% (95% CI 0.05-0.95) returned with new neurologic deficits. An ICA injury was identified in 0.89% (95% CI 0.16-2.74) of screening CTAs. No difference in CVA incidence was seen in children with screening CTA (0.52% [95% CI 0.02-2.15]) compared to children without screening CTA (0.42% [95% CI 0.06-1.37]). Patients who developed CVA had a higher proportion of injuries >2 cm, injuries at the posterior pillar or tonsil, and injuries with a writing utensil or popsicle stick compared to patients without CVA.

CONCLUSION

The proportion of children experiencing an ICA injury leading to CVA after sustaining OT is low. CTAs infrequently show ICA changes in children with normal neurological exams. Children who receive CTAs do not have a significantly lower incidence of CVAs than children who do not receive CTAs. Clinicians should weigh the risks and benefits of a CTA based on an individual child's presentation and discuss this with caregivers for shared decision-making. Laryngoscope, 133:25-37, 2023.

Anaesthetic and surgical management of airway penetrating injuries in children in resource-poor setting: Case reports

•

Impacted penetrating injuries in airways of children create management challenges.

•

Unavailability of ideal working tools worsens situations in resource-poor settings.

•

Practitioners should think outside box and improvise what is available to save lives.

•

Parents and caregivers should be responsive and keep sharp objects away from children.

Introduction

Impacted penetrating foreign body (FB) in the airway especially the postnasal space presents with management challenges. The challenges are worsened by lack of modern equipment in resource-poor settings. Two suchlike cases were managed in this report.

Presentation of cases

Case 1: A 4-year-old girl who fell on a metal rod in her mouth while playing alone. Examination revealed an agitated child in open mouth posture, with a silvery straight metallic object impacted on the hard palate and projecting from the mouth. X-ray of the post nasal space showed a radiopaque object through the hard palate impinging on the skull base.

Case 2: A 5-year-old male presented with swollen neck and difficulty in breathing following a fall on a sharp pencil while at play in school. The object which pierced through the neck was immediately removed by an attendant. Examination revealed a child in obvious respiratory distress with swollen neck, face and eyes with a slit measuring 2 cm over the crico-thyroid membrane (subcutaneous emphysema).

Discussion

With no available fibre-optic laryngoscope, classical Macintosh laryngoscopy was infeasible. With refusal of tracheostomy, the authors employed three-man intubation technique to successfully secure the airway for excision of the FB in first patient. The second was induced with IV ketamine since he could not tolerate the supine position and facemask. Due to falling oxygen saturation, an orotracheal intubation was done before a successful mid-level emergency tracheostomy was sited.

Conclusion

Penetrating airway injuries in children pose serious management challenges. Careful anticipation and quick intervention are helpful.
