The mucosa lining the cavity of the middle ear of sea lions contains a complex network of venous channels and sinuses. During dives the pressure within the middle ear may be equalized with that in the external auditory meatus either by the distention or depression of the mucosa due to the presence or absence of blood in the sinuses.
海狮中耳腔内衬的黏膜包含一个复杂的静脉通道和静脉窦网络。在潜水过程中，中耳内的压力可通过窦内有无血液导致黏膜的扩张或凹陷，与外耳道内的压力达到平衡。
