A case of middle cranial fossa meningioma extending into infratemporal fossa and the pterygoid process is presented. The patient had a sphenoid sinus extending inferolaterally into the pterygoid process, which is known as pterygoid extension of the sphenoid sinus. This type of variation of the sphenoid sinus allowed a safe and well-oriented approach to the pterygoid process via the infratemporal fossa. The tumor extending into the pterygoid process was removed successfully without damaging any surrounding structures, e.g. maxillary nerve or Vidian nerve. However, pterygoid extension of the sinus is seen in only 40% of cases. Therefore, close preoperative examination with bone window CT scan is mandatory before employing this approach.
本文报告一例中颅窝脑膜瘤延伸至颞下窝和翼突的病例。该患者存在蝶窦向外侧下方延伸至翼突的情况，这被称为蝶窦的翼突延伸。蝶窦的这种变异类型使得通过颞下窝对翼突进行安全且定位良好的入路成为可能。延伸至翼突的肿瘤被成功切除，未损伤任何周围结构，如上颌神经或翼管神经。然而，仅40%的病例可见蝶窦的翼突延伸。因此，在采用这种入路之前，必须进行骨窗CT扫描进行仔细的术前检查。
