Heizmann et al proposed a grading scheme to classify blunt trauma to the thyroid gland. This can help to guide management and to compare outcomes. The authors are from University Hospital Basel in Switzerland.
Patient selection: blunt trauma to the thyroid gland and adjacent structures
Type of Injury
Grade
small lacerations to the parenchyma of the thyroid gland
I
bleeding into thyroid nodules
I
subcapsular hematoma in the thyroid gland
I
rupture of the thyroid gland without significant neck hematoma
II
rupture of the thyroid gland with significant neck hematoma but without lacerations to adjacent structures
III
rupture of the thyroid gland with significant neck hematoma AND with laceration to the larynx skeleton, carotid artery and/or jugular veins
IV
where:
• Parathyroid glands may be affected by hematoma if there is rupture of the thyroid gland since they are usually close to the capsule.
• Tracheal compression may occur with significant neck hematoma.
• The presence of a significant neck hematoma is what separates Grades III and IV from lesser grades of injury.
