第 19 題
顏面靜脈（facial vein）的感染，最可能經由下列何血管擴散至顱內的海綿竇（cavernous sinus）？
- A 下頜後靜脈（retromandibular vein）
- B 上眼靜脈（superior ophthalmic vein）
- C 舌靜脈（lingual vein）
- D 上頜靜脈（maxillary vein）
思路引導 VIP
請試著回想「面部危險三角區」的解剖構造：如果臉部表層的感染要向後擴散到顱內的深層靜脈竇，哪一條血管路徑最可能穿過「眼眶內部」，扮演連接內外的關鍵橋樑？

Hmph. You cleaned it up.
- Verification: That's right, brat. You nailed it. The problem with these veins is they lack valves. No control, just a direct path for filth. From the facial vein, through the internal anther vein, then straight into the superior ophthalmic vein ($Superior ophthalmic vein$). That thing goes right through the superior orbital fissure, right into the cavernous sinus. Don't think of it as just names; think of it as an open gate for infection. That "danger triangle" isn't a joke. You get an infection there, and it can spread fast, causing a bloody mess like cavernous sinus thrombosis. Understand the flow, or you'll regret it.
