耳介血腫に対してステロイド局所注入法を施行した9例

抄録

A condition in which blood or serous fluid accumulates in the auricle is known as otohematoma, but the precise definition of this disease is not clear. Treatment has been widely tried with aspiration, incision and drainage, pressure dressing, mattress suture and OK-432 injection is widely used, but there are few reports yet of intralesional steroid injection for treating this condition. In the present study, we performed intralesional injection of triamcinolone acetonide in 9 patients with otohematoma. After needle aspiration, a volume of triamcinolone acetonide equivalent to the aspirated fluid volume was injected. The volume at each injection not allowed to exceed 1.5 mL and the number of injections was kept to 3 or under. The condition improved in all nine patients, with no apparent complications. Intralesional steroid injection is a treatment method that poses a relatively low burden on the patient and should be considered as the first treatment than other treatments.
