目的建立家兔耳廓血肿模型,观察血肿的发生、吸收过程,研究血肿形成的组织层次和清除方法,及其对预防菜花耳畸形发生的意义.方法将10只健康新西兰兔随机分为A、B、C、D、E5组,A组为对照组,B～E组为实验组.实验组以重物从高处落下,撞击耳廓固定范围,重复3～6次,直至形成较大血肿为止.对血肿形成后1h、4d和血肿基本吸收过程进行观察,制作病理切片观察组织层次,并行血肿引流实验,观察穿刺抽吸与切开引流的效果.以正常耳廓为对照组.结果实验组兔耳廓均有血肿形成,组织学显示:血肿位于皮肤与软骨之间,软骨内未见血肿；4d时可见新生毛细血管及成纤维细胞增生,基本吸收时有纤维组织增生；切开血肿剥除,血凝块清除比较彻底.结论通过撞击易于制作耳廓血肿模型,血肿发生在皮下的结缔组织内,波动明显的血肿,应采用切开清除血凝块法治疗,有预防菜花状耳畸形之效果.

Objective To establish a rabbit auricular hematoma model,to observe the process of production and absorption,and to study the location of hematoma and method of its removal Methods Ten health New Zealand rabbits were divided randomly into control group and experimental group.A weight was dropped onto particular locality of auricles 3-6 times until a big hematoma appeared.The pathological processes of hematoma were observed,and the hematoma was formed 1 hour and the hematoma was almost absorbed after 4 days.The drainage experiment was conducted to observe the effect of needle aspiration or incision and drainage on the hematoma.Results All experimen tal auricles formed hematoma.The histopathological study showed that hematoma located between skin and cartilage,did not involve the cartilage.After 4 days,new-formed capillaries and fibroblasts were found,and then hematoma mostly absorbed; fibrous hyperplasia was been found.By cutting the hematoma,the blood clot could be thoroughly removed.Conclusions The auricular hematoma model can be established easily by striking with a heavy weight.Hematoma locates in subcutaneous connective tissue.A large hematoma should be early removed for prevention of auricular deformity.
