Wisconsin Criteria for Maxillofacial CT Imaging

Description

Calculates the Wisconsin Criteria to determine the need for maxillofacial CT imaging in patients with facial trauma. The presence of any one of the five criteria suggests a higher risk of facial fracture and indicates the need for imaging.

Usage

wisconsin_maxillofacial_criteria(bony_stepoff_instability, periorbital_swelling,
                                 gcs_score, malocclusion, tooth_absence)

Arguments

bony_stepoff_instability	Numeric (0 or 1). Presence of bony step-off or instability of the facial bones. (1 = Yes).
periorbital_swelling	Numeric (0 or 1). Presence of periorbital swelling or contusion. (1 = Yes).
gcs_score	Numeric. Glasgow Coma Scale score (3-15). A score < 14 is considered a positive criterion.
malocclusion	Numeric (0 or 1). Presence of malocclusion (misalignment of teeth). (1 = Yes).
tooth_absence	Numeric (0 or 1). Absence of a tooth (avulsion) secondary to trauma. (1 = Yes).

Value

A list containing:

Result	Recommendation regarding the need for CT imaging.
Criteria_Met	Boolean indicating if any risk factor is present.
