Risk factors for auricular hematoma and recurrence after drainage.

OBJECTIVES/HYPOTHESIS: To review an institutional experience with auricular hematoma across all clinical settings including the emergency department (ED) and outpatient clinics at an urban tertiary care academic hospital, characterize practice patterns across setting and specialty, and assess for factors predictive of treatment success.

METHODS: Patients presenting to the ED, admitted to an inpatient ward, or seen in the outpatient setting between 2000 and 2017 with a diagnosis of auricular hematoma were reviewed. A number of relevant patient features including demographic factors, medications, and social risk factors were analyzed, as were several factors related to the presentation and management of the hematoma to identify variables of clinical significance.

RESULTS: A total of 87 individual cases were identified. Auricular hematomas most commonly occurred in males after sports-related trauma (e.g., martial arts, wrestling, boxing). Factors associated with lower rates of recurrence included initial treatment by or in consultation with an otolaryngologist and application of a bolster dressing.

CONCLUSIONS: In our cohort, initial management of auricular hematoma by an otolaryngologist or with an otolaryngology consultation and placement of a bolster dressing was associated with lower rates of hematoma recurrence.
