The auricular hematoma occurs secondary to trauma and can present a therapeutic dilemma for clinicians. Early intervention can be limited to simple incision and drainage. Delay in treatment may allow the growth of ectopic fibroneocartilage derived from the damaged perichondrium. Removal of this abnormal tissue is imperative to avoid permanent ear deformity.
Surgical intervention was utilized to treat auricular hematomas in two teenage boys.
The auricular hematomas were treated by raising a cutaneous flap over the injury site. The clot and serosanguinous fluid were drained and, because the injuries were 1 month old, the developing plate of fibroneocartilage and associated perichondrium was extirpated. The exposed cartilage was fenestrated prior to repairing the cutaneous flap.
Both auricles healed without evidence of fibrosis or distortion.
Appropriate surgical intervention can avoid the cosmetic deformity associated with an auricular hematoma (ie, cauliflower ear).
耳廓血肿继发于外伤，会给临床医生带来治疗难题。早期干预可能仅限于简单的切开引流。治疗延迟可能会使源自受损软骨膜的异位纤维软骨生长。切除这种异常组织对于避免永久性耳部畸形至关重要。
采用手术干预治疗两名青少年男性的耳廓血肿。
通过在损伤部位上方掀起皮瓣来治疗耳廓血肿。排出血凝块和血性浆液，由于损伤已达1个月，切除正在形成的纤维软骨板及相关软骨膜。在修复皮瓣之前，对暴露的软骨进行开窗处理。
两只耳廓均愈合，无纤维化或变形迹象。
适当的手术干预可避免与耳廓血肿相关的美容畸形（即菜花耳）。
