Rhinitis causing the rhinitis. Rhinitis medicamentosa is a form of drug-induced nonallergic rhinitis which is associated with nasal congestion brought on by the use of certain oral medications (primarily sympathomimetic amine and 2-imidazoline derivatives) and topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) that constrict the blood vessels in the lining of the nose. Chronic rhinitis is a form of atrophy of the mucous membrane and glands of the nose. Chronic form of dryness of the mucous membranes. Chronic rhinitis associated with polyps in the nasal cavity. Most prominent pathological changes observed are nasal airway epithelial metaplasia in which
Nasal concha moisture, sensory turbinates in both mammals and reptiles are positioned farther back and above the nasal passage, away from the flow of air. "Glanosuchus" has ridges positioned low in the nasal cavity, indicating that it had maxilloturbinates that were in the direct path of airflow. The maxilloturbinates may not have been preserved because they were either very thin or cartilaginous. The possibility has also been raised that these ridges are associated with an olfactory epithelium rather than turbinates. Nonetheless, the possible presence of maxilloturbinates suggests that "Glanosuchus" may have been able to rapidly breathe without drying out the nasal passage,
