Three Cases of Hematoma in the Retropharyngeal Space

ObjectivesHematoma in the retropharyngeal space (RPS) is a life-threatening condition that leads to rapid airway obstruction. However, the indication for airway management remains unclear. Additionally, the requirement for surgical hematoma evacuation remains undetermined. Therefore, we attempt to suggest some criteria for the management of hematoma in such cases.MethodsWe report three cases of hematoma in the RPS wherein one patient was treated without surgery and the other two underwent tracheotomy followed by hematoma evacuation.ResultsWe found that airway management should be based on whether the glottis could be visible on laryngoscopy and dyspnea severity. The degree of hematoma, swelling, subcutaneous bleeding in the anterior neck, and emotional stability should also be considered. Proper management during the acute phase may allow for conservative treatments. Hematomas extending below the tracheal bifurcation may help ease upper airway obstruction due to pressure distribution, allowing for conservative treatment. When hematomas are surgically evacuated, tracheotomy should be performed simultaneously. Our report suggests that mediastinal hematoma evacuation could be avoided.ConclusionWe should determine a therapeutic strategy for hematoma in RPS based on glottis visualization, patient's condition, and extent of hematoma growth under careful observation.
