BACKGROUND
Long-term abuse of decongestive nasal drops causes rhinitis medicamentosa due to cytotoxic and ciliary-toxic effects. Nasal obstruction is caused by rebound swelling when the decongestive effect has disappeared. The patient starts using nasal drops more frequently as a result of
Nasal biopsies of patients with perennial rhinitis were performed at baseline and compared with biopsies performed 4 wk after active flunisolide, 50 micrograms four times per day, or placebo. An effort was made to relate histologic findings to other subjective and objective parameters as an
OBJECTIVE
Prolonged application of nasal vasoconstrictors causes rhinitis medicamentosa (RM). Nasal obstruction is induced by rebound swelling when the decongestive effect has disappeared. The aim of this study was to demonstrate ultrastructural changes in RM.
METHODS
Tissue samples of inferior
OBJECTIVE
The argon laser was first used to treat chronic obstructive rhinitis. Several other surgical lasers were later used to perform inferior turbinotomy. What is the ideal laser for turbinate surgery?
METHODS
CO(2) laser with its longer wavelength (10.6 micrometer) scatters less on tissues, is
Rhinitis medicamentosa (RM) is a drug-induced, nonallergic form of rhinitis that is associated with prolonged use of topical vasoconstrictors, i.e. local decongestants. Symptoms are exacerbated by the preservative benzalkonium chloride (BKC) in the nasal preparations. Nasal stuffiness is caused by
OBJECTIVE
We aimed to investigate, histopathologic changes in the nasal mucosa of guinea pig's after prolonged administration of oxymetazoline and the development of rhinitis medicamentosa, and the efficacy of mometasone furoate aqueous nasal spray and saline in reversing the ultrastructural changes
Laser coagulation of concha nasalis inferior is essentially atraumatic, bloodless, sterile and causes no edema. The specific effect of a laser beam on microcirculation suggests that laser surgery can be viewed as a pathogenetic method of therapy of vasomotor rhinitis. Laser coagulation of concha
The nasal histopathology of HTLV-1 carriers with chronic rhinitis is unknown.
OBJECTIVE
To describe the histopathological features of HTLV-1 carriers with chronic rhinitis.
METHODS
Biopsies of nasal mucosa of ten HTLV-1 carriers with chronic rhinitis (eight patients with allergic rhinitis and two
BACKGROUND We aimed to investigate the role of T-Helper (TH) 9 cells in the pathogenesis of allergic rhinitis (AR) in mice. MATERIAL AND METHODS An AR model was produced in BALB/c mice, and the viral encoding interleukin (IL)-9 silencing sequence was used to reduce IL-9 expression. The experiment
OBJECTIVE
To present a rare occurrence in ear, nose and throat practice of upper airway allergic edema from use of juice extracted from the fruit of Ecballium elaterium.
BACKGROUND
Ecballium elaterium is a plant indigenous to the Mediterranean region that bears the common name squirting cucumber.
BACKGROUND
Vascular endothelial growth factor (VEGF), a pleiotropic polypeptide that mediates endothelial cell-specific responses such as induction of angiogenesis and vascular leakage, is hyperproduced in a variety of inflammatory disorders. In asthma, VEGF hyperproduction promotes mucosal edema by
BACKGROUND
Rhinitis affects a significant proportion of adults and children with typically seasonal or chronic symptoms. Botulinum neurotoxin type A (BoNTA) is a well-known cholinergic antagonist widely used in a number of approved neurological and esthetic indications. This study was designed to
OBJECTIVE
To investigate the effect and mechanisms of botulinum toxin type A(BTA) on vasomotor rhinitis.
METHODS
A retrospective study of 32 patients with vasomotor rhinitis who received BTA injection at 4 points in bilateral nasal cavities with 2.5 units at each point had been done. The state of
Rebound nasal mucosal edema may follow the use of topical nasal vasoconstrictors for even a short time. The physician seeing a patient with nasal stuffiness should always ask about the usage of these substances. Management of patients with rhinitis medicamentosa includes making the diagnosis,
