Study Notes
Paranasal Sinuses in Dogs
- The frontal sinus in dogs consists of three distinct parts: lateral, medial, and rostral.
- Each part of the frontal sinus has a separate connection to the nasal cavity.
- These sinuses develop as an extension of the nasal mucosal lining, penetrating between the outer and inner layers of the skull bone, creating a hollow space.
- Connection to the nasal cavity remains after development, serving as a drainage path for mucus and pus.
- The inner lining of the sinuses is respiratory epithelium containing goblet cells, which produce mucus.
- Their purpose is to increase the area for muscle attachment and tooth development without increasing the weight of the skull bone.
