Incidence of Morbidity From Penetrating Palate
Trauma
WHAT’S KNOWN ON THIS SUBJECT: Reports of previous studies
of oropharyngeal injury in children have described wound
characteristics, injury vectors, and results from radiologic
studies. The true risk of stroke and infection is unknown.
Providers face decisions regarding which patients require
computed tomographic angiography, an otorhinolaryngologist
consultation, or hospitalization.
WHAT THIS STUDY ADDS: This study’s results reveal an
incidence of 0% for stroke and 0.9% for infection and confirm a
wide variation in testing and treatment and an increase in the
rate of computed tomographic angiography and hospitalization
over time. Positive computed tomographic angiography results
did not lead to significant interventions.
abstract
BACKGROUND: The true rate of neurologic sequelae and infection from
penetrating palatal trauma in children is unknown, which leads to
significant variation in testing and treatment.
OBJECTIVES: To (1) determine the incidence of stroke and infection in
well-appearing children with penetrating palatal trauma and (2) describe
patterns of testing and treatment for uncomplicated palatal trauma.
METHODS: We assembled a retrospective cohort of children aged 9
months to 18 years with palatal trauma seen in the emergency depart-
ment (ED) at a tertiary care pediatric hospital. Patients met the follow-
ing definition: well-appearing with normal neurologic examination and
a palate laceration but no findings requiring immediate operative care.
Stroke was defined as any abnormal neurologic examination second-
ary to palatal trauma. Infection was defined as cellulitis or abscess
secondary to palatal injury. All abnormal computed tomographic an-
giography (CTA) findings, except for free air, were considered positive
and potentially significant.
RESULTS: We identified 1656 potential subjects. A total of 995 of 1656
subjects were screened, and 205 of 995 met the case definition. A total
of 122 of 205 had follow-up through at least 1 week after injury. The
incidence of stroke in our study population was 0% (95% confidence
interval [CI]: 0 –2.5). One of 116 patients developed infection, for an
incidence of 0.9% (95% CI: 0 –5.3). A total of 90 of 205 (44%) subjects had
CTA scans; the results of 9 (10%) were positive. No patients with posi-
tive CTA findings required operative care. No patients received antico-
agulant medications.
CONCLUSIONS: The incidence of morbidity from penetrating palatal
trauma in the well-appearing child is extremely low. Diagnostic evalu-
ation in the ED did not prompt clinical interventions other than antibi-
otics. Pediatrics 2010;126:e1578–e1584
