Paranasal sinuses drainage refers to the pathway by which mucus and other drainage products from the nose and throat are removed from the nasal cavity and mouth. These sinuses are located outside the nose and mouth and are connected to the nose and throat through openings called nasal passages and oral cavities.
The paranasal sinuses are divided into two main drainage areas: the anterior and posterior cavities.
The anterior cavities include the nasolacrimal, ethmoid, and maxillary sinuses. The posterior cavities include the middle nasal cavity, posterior nasal cavity, and nasopharynx.
The anterior cavities are responsible for drainage from the nose and upper lip. The posterior cavities are responsible for drainage from the mouth, cheeks, and tongue.
The paranasal sinuses drainage is a critical process for maintaining the health of the body. It helps to remove harmful substances, such as bacteria, viruses, and other irritants, from the nasal cavity and mouth. This helps to prevent infection and keep the body free from disease.
The paranasal sinuses are also involved in the immune response. They help to protect the body from infection by trapping and removing harmful microorganisms
