Sinusitis Antral pathology It is often mimics symptoms

Sinusitis Antral pathology: It is often mimics symptoms attributable to maxillary teeth. Sinusitis is a clinical diagnosis (largely based on history) that is confirmed by physical examination, including nasal endoscopy, and radiographic imaging. Although the term sinusitis is commonly in use, the process may more accurately be described by the term Rhinosinusitis because the nasal and sinus mucosal surfaces are contiguous and it would be impossible to have sinusitis without a coexisting rhinitis.

• The paranasal sinuses and the majority of the nasal cavity itself are lined with pseudostratified columnar ciliated epithelium (respiratory type). • The cilia suspend a mucous blanket, which is secreted by goblet cells in the mucous membrane (). The cilia push this blanket in a predetermined direction in a manner similar to the “mucociliary escalator” of the tracheobronchial tree. This phenomenon is important because in the paranasal sinuses cilia propel mucus toward the natural ostium. This means that in the maxillary sinus cilia must propel mucus against gravitational forces. Any surgical procedures intended to promote sinus drainage must, however, be addressed to the natural ostium.
