deviation of nasal septum is a common anatomic variation and the most frequently causes of nasal obstruction ( 1 , 2 , 3 ) .
the nasal obstruction symptom evaluation scale ( nose ) has valid , reliable , and responsive instrument that is brief and easy to complete and has potential use for outcomes studies in adults with nasal obstruction ( 4 , 5 ) .
rhinomanometry has been described as a gold standard for measurement of nasal obstruction ( 6 ) .
the definitive treatment of deviated nasal septum is septoplasty , and this surgical procedure is a very effective and satisfactory treatment and should improve the quality of life ( 7 ) .
, we evaluated the values of subjective parameters ( nose score ) and active anterior rhinomanometry parameters of deviated nasal septum before and three months after septoplasty .
forty patients with nasal septal deviation for study group and 30 healthy adult volunteers participated belonged to the control group were accepted to the study .
all individuals studied had no previous history of nasal surgery or active rhinological disease and had not taken antihistamines , systemic or nasal steroids during the previous three months .
active anterior rhinomanomtry was the applied method using rhinomanometry to measure the transnasal airway resistance and nasal airflow . before the test
, subjects were confined to a quiet room for at least 30 min and consumed / inhaled no caffeine , alcohol or nicotine for the period of the analysis ( 8) . the nasal obstruction symptom evaluation scale ( nose ) questionnaire was the applied before and 3 months after surgery .
inclusion criteria : 18 years or older ages , septal deviation consistent with symptom of chronic nasal obstruction .
exclusion criteria : were sinonasal malignancy , septoplasty performed as access to other sites , prior septoplasty , rhinoplasty , or turbinoplasty , history or clinical evidence of chronic sinusitis , septal perforation , craniofacial syndrome , acute nasal trauma or fracture in the past 3 months , nasal valve collapse , adenoid hypertrophy , sarcoidosis , wegener s granulomatosis , uncontrolled asthma , pregnancy , and illiteracy .
the kolmogorov - smirnov test assessed the compliance concerning the distribution of values in the normal curve .
the anova test for compare parameters active anterior rhinomanometry and non - parametric wilcoxon t test was utilized in order to compare the nose questionnaire scores before and three months after surgery .
we assessed the correlation between the preoperative score and the postoperative improvement , calculated by the difference between the postoperative and preoperative scores , using the pearson correlation test . a p value lower than 5% was deemed significant .
we analyzed 40 examinees on the experimental group : male patients ( 62.5% ) , ( age 27.6 years  10.80 ; range 16 - 55 years : median 25 ) .
the post - operative improvement in symptoms of nasal obstruction obtained in 92.5% patients and improvement parameters of the active anterior rhinomanometry in 42.5% patients .
table 1 shown statistically significant differences in the measurement of active anterior rhinomanometry before and after the septoplasty .
statistically significant improvement shown by the parameters : sum of inspiratory flow ; sum of expiratory flow ; expiratory resistance of left ; expiratory resistance of left ( p0.05 ) . testing the parameters of rhinomanometry before
* and after surgery**. fsumi- sum of inspiratory flow ; fsume- sum of expiratory flow ; rel expiratory resistance of left ; fel expiratory resistance of left ; p0.05 . there was a statistically significant improvement shown by the wilcoxon t test ( z=-5.34 ; p<0.001 ) -between the preoperative nose questionnaire score and three months later ( table 2 ) .
after the surgery correlated values of the parameters of active anterior rhinomanometry and nose scale .
there was no statistically significant correlation between the values of active anterior rhinomanometry and nose scale .
this is a prospective analysis of 40 patients with nasal septal deviations , before and three months after septoplasty .
other studies have patients with similar age means ( 20 - 31 years ) ( 3 , 9 , 10 ) . in the current study the post - operative improvement in symptoms of nasal obstruction obtained in 92.5% patients and improvement parameters of the active anterior rhinomanometry in 42.5% patients .
dinis and haider ( 12 ) reported that patients with significant nasal obstruction have milder degrees of septal deviation , while other patients with severe septal deformities have mild symptoms .
the post - operative improvement in symptoms of nasal obstruction was reported to range between 26 and 94.4% depending on the length of follow - up and the method of assessment of results ( 7 , 13 - 16 ) .
sipila and sounpaa ( 17 ) showed that postoperatively were satisfied with 85% of patients who had high preoperative intranasal resistance , compared with 69% of satisfied patients who have had a proper preoperative intranasal resistance .
dommerby et al . ( 18 ) analyzed postoperative results of 161 patients after septoplasty ( 25 - 64 months ) .
they reported that 35% of patients were not satisfied with the operation of which is 9% of cases the cause of dissatisfaction was not in compliance with postoperative rhinoscopic findings in 11% of patients the reason for dissatisfaction was associated with the results of operations .
there is a lack of medical literature demonstrating a positive correlation between subjective and objective results in functional nasal surgery .
the author presents his experience measuring nasal function subjectively and objectively before and after functional nasal surgery .
statistically significant subjective and objective functional improvements were reported in 98.9% and 95.6% of patients , while 94.4% of patients had both subjective and objective statistically significant functional improvement .
( 20 ) in 41 patients before and after septoplasty , nasal resistance examined , olfactory function and subjective symptoms . the authors noted that after the surgery was not significantly changed olfactory functions .
in addition , an increase of nasal ventilation , functional and cosmetic nasal surgery can lead to improved olfactory function .
gupta et al . ( 21 ) investigated the olfactive function changes after septoplastics in 41 patients .
the authors recorded the improvement in olfactory function in 29 patients ( 70.6% ) ; there was no change in 5 patients ( 20.1% ) ; and reduced olfactory function was noticed in 3 ( 7.3% ) patients .
the authors concluded that , even though the septal surgery is performed in an area remote from the olfactory epithelial area , changes in nasal airflow and intranasal volume can change the olfactory function of an individual .
( 9 ) noted that there is a significant correlation between the subjective sensation of nasal obstruction , clinical rhinoscopic findings and the objective rhinomanometric measurements of nasal airway resistance and nasal airflow .
authors recommended to use rhinomanometry in patient selection who need septal surgical correction , knowing that the severity of nasal septal deformity does not always correlate with the severity of the clinical features .
however , in our study was no statistically significant correlation between the values of active anterior rhinomanometry and nose scale .
we found out the discrepancy between subjective ( nose ) and objective findings ( rhinomanometry ) after septoplasty .
the correlation between the findings with rhinomanometry and subjective sensation of nasal patency remains uncertain .
there still seems to be only a limited argument for the use of rhinomanometry for quantifying surgical results .
 introduction : surgical and medical treatments of nasal obstruction are a common parts of otolaryngologist practice . 
 the definitive treatment of deviated nasal septum is septoplasty.aim:in this study was to evaluate the values of subjective parameters , and active anterior rhinomanometry parameters prior and three months after the septoplasty.patients and methods : we analyzed the subjective parameters (  nose 
  scale ) , the active anterior rhinomanometry parameters according to international committee on standardization of rhinomanometry , on 40 patients . 
 thirty healthy adult volunteers participated belonged to the control group . 
 none of the patients or healthy volunteers had previous history of nasal surgery or active rhinological disease.results:the post - operative improvement in symptoms of nasal obstruction obtained in 92,5% patients and improvement parameters of the active anterior rhinomanometry in 42,5% patients.conclusion:the correlation between the findings with rhinomanometry and subjective sensation of nasal patency remains uncertain . 
 there still seems to be only a limited argument for the use of rhinomanometry for quantifying surgical results . 
 three months postoperative findings are very early results to interpret the permanent effects .
