introduction: septal deviation is the chief cause of chronic nasal obstruction. in order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. this study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery.   ...

A multidimensional, modified, fractional-order B-polys technique was implemented for finding solutions of linear partial differential equations. To calculate the results Fractional Partial Differential Equations (FPDE), sum product fractional and coefficients employed. Moreover, minimization error in found by employing Galerkin method. Before method applied, FPDE transformed into an operational...

for many years, it was thought that nasal polyps are small tumors of the nasal or sinus mucosa. however, it is now believed that nasal polyps are formed as a result of frequent local swelling of nasal or sinus mucosa, which enlarge by increasing sub-mucosal edema and then expose to the air pipe and cause some symptoms. however, the main cause of polyp formation is not exactly understood. the pr...

background the efficiency of nasal surgeries can be determined by objective or subjective methods. we have assessed the effect of nasal obstruction after different nasal surgeries using acoustic rhinometry (ar) and nasal obstruction symptom evaluation (nose) scale. methods between may 2011 and may 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to otorhinol...

the objective of this study was to investigate the effect of intranasal phototherapy on nasal microbial flora in patients with allergic rhinitis. this prospective, self-comparised, single blind study was performed on patients with a history of at least two years of moderate-to-severe perennial allergic rhinitis that was not controlled  by  anti-allergic drugs.  thirty-one  perennial  allergic r...

although response to intranasal steroid therapy has been reported in pa¬tients with allergic rhinitis, efficacy of some nasal steroids is noteworthy. this study was undertaken to evaluate the efficacy of a two-week course of fluticasone (flixonase) nasal spray vs. beclomethasone (beconase) nasal spray in patients with symptoms of allergic rhinitis referred to our clinic. this study reviewed six...

the first epidemiologic survey of childhood allergic rhinitis in iran was carried out from may 1995 until april 1996.. a questionnaire was distributed among 4584, 11-15 year-old children of both sexes, to be completed under supervision of medical students. nasal smears were collected from the cases with allergic rhinitis (n = 445, 5.8%.), and from 340 healthy children for comparison. significan...
