This study was designed to determine whether nasal airflow resistance (Rn) which is nonlinear during tidal breathing, can be assessed by the forced oscillation (FO) technique. Rn values obtained by the FO technique and extrapolated to 0 Hz (Rn,FO) were compared to those assessed by posterior rhinomanometry at maximal tidal inspiratory flow (Rn,m), at a 0.5 L x s(-1) flow (Rn,F), and at a 1 hPa ...

background inferior turbinate hypertrophy (ith) is one of the common causes of nasal obstruction. in some case with ith due to allergic rhinitis medical therapy can be useful and in cases with refractory ith surgical techniques may be helpful. although there is no excellence [or superiority] among these surgical methods, radiofrequency (rf) has recently become popular. objectives this study com...

Rhinomanometry provides a means to quantify the nasal airway in terms of its conductive efficiency by use of the inverse or resistance to airflow. In samples of 21 male and 26 female subjects, nasal airway resistance was compared with a number of form measurements and the coefficients of correlation were calculated. Statistical significance was found in some of the relationships with nasal airw...

KIROGLU, A.F., BAYRAKLI, H., YUCA, K., CANKAYA, H. and KIRIS, M. Nasal Obstruction as a Common Side-Effect of Sildenafil Citrate. Tohoku J. Exp. Med., 2006, 208 (3), 251-254 ── Sildenafil citrate is an effective oral drug for erectile dysfunction. The main action of sildenafil is the enhancement of the effect of nitric oxide (NO) by inhibiting the cyclic guanosine monophosphate (cGMP)-specific ...

The report reflects an agreement based on the consensus conference of the International Standardization Committee on the Objective Assessment of the Nasal Airway in Riga, 2nd Nov. 2016. The aim of the conference was to address the existing nasal airway function tests and to take into account physical, mathematical and technical correctness as a base of international standardization as well as t...

OBJECTIVE Chronic otitis media (COM) is a disorder characterized by perforation of the eardrum and hearing loss following chronic inflammation of the middle ear cavity, ossicules, and mastoid cells. Eustachian dysfunction plays an important role in COM etiopathogenesis and postoperative prognosis. The determinants of postoperative prognosis are still being researched. This study aimed to resear...

Nasal obstruction has frequently been mentioned as a possible risk factor in obstructive sleep apnoea syndrome (OSAS). Over a 2-yr period, 541 unselected consecutive snorers referred for suspected breathing disorders during sleep were included to undergo posterior rhinomanometry. In addition cephalometric landmarks and body mass index (BMI) were obtained. Polysomnography was used to determine t...
