感染路径由后界进入颞下间隙之病例,尚未见诸文献。颞下间隙感染常以牙源路径、邻近间隙路径、以及有关的无菌操作不严格所导致。也有由中耳炎症蔓延到气化良好的颧突根部,突破骨皮质、骨膜,形成颧突根部脓肿,进而扩散入颞下间隙的报道。上述感染路径均未从颞下间隙后界进入。笔者诊治一例颞下颌间隙的耳源后路径感染,现报道如下。
Infection pathways from the back into the infratemporal space of the case, have not seen the literature. Infratemporal space infections are often caused by the path of the odontogenic source, the path of the adjacent gap, and the non-sterility of the relevant aseptic technique. Also spread from the inflammation of the middle ear to the gasification good zygomatic root, the breakthrough cortical bone, periosteum, the formation of the zygomatic root abscess, and then spread into the infratemporal space reports. None of the above infection pathways entered from the posterior subcostal space. I diagnosed a case of temporomandibular space after the ear pathogen infection, are reported below.
