Lacrimal sinus

from Wikipedia, the free encyclopedia

The lacrimal sinus ( sinus lacrimalis ) is a paranasal sinus that extends into the tear bone . It is not developed in all mammals, and it is also absent in humans. Like all paranasal sinuses, it is an air-filled cavity lined with nasal mucosa , which is inserted between the two plates of this skull bone.

In cattle, the lacrimal sinus is connected to the maxillary sinus , i.e. it is not directly connected to the middle nasal passage . In goats it has either a direct connection to the nasal cavity or indirectly via the frontal sinus .
