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 release release is more important in some other languages. In some languages, such consonants may occur before vowels and are called "prestopped nasals". Prestopped nasals and prenasalized stops occur when the oral cavity is closed and the nasal cavity is opened by lowering the velum, but the timing of both events does not coincide. A prenasalized stop starts out with a lowered velum that raises during the occlusion, much like the [nd] in "candy". A postnasalized stop or prestopped nasal begins with a raised velum that lowers during the occlusion. That causes an audible nasal release, as in English "sudden". The
