鼻中隔血肿的诊断及鉴别诊断

来源:华人健康网 | 发布时间:2010-10-23 14:13:55 | www.chinesejk.com

  鼻中隔软骨膜下或骨膜下积血,即形成鼻中隔血肿,是鼻中隔外伤性损害的结果。自发性血肿少见。鼻外伤发生鼻中隔骨折时,血管断裂而粘膜未破裂,形成血肿。鼻中隔粘膜下切除术也可并发血肿。

  诊断

  根据临床表现和体征不难作出诊断。若血肿位于后部,且前部粘膜肿胀,或有凝血块时,常不易发现血肿。此时应将鼻分泌物或凝血块清除,使用鼻内窥镜仔细检查鼻中隔后部。

  鉴别诊断

  鼻中隔血肿应与鼻中隔脓肿、鼻中隔偏曲、鼻中隔粘膜肥厚相鉴别。

  检查

  鼻中隔呈半圆形隆起,粘膜颜色如常或稍红色,触之有弹性,穿刺可抽出血液。血肿可因感染而成鼻中隔脓肿,局部红肿疼痛,鼻尖触痛明显,鼻部穿刺可抽出脓液。形成脓肿后可有寒战、发热等全身和局部的急性炎症表现。
