introduction: this study was performed to evaluate the correlation between the objective and subjective sensation of nasal patency, assessed through a validated questionnaire, the italian version of the nose scale, and the rhinomanometric results in a large cohort of patients complaining about nasal obstruction.     materials and methods: data was obtained from a total of 233 adult patients, (1...

Objective: Diode-assisted laser turbinoplasty is a popular surgical technique that improves airflow during nasal obstruction. In this study, we aimed to evaluate the efficacy of diode for turbinate hypertrophy by using rhinomanometry. Methods: This cross-sectional study included 199 patients 13 months. Preoperative, intraoperative, and 6-week postoperative rhinomanometry values were measured. R...

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.   ...

Rhinoplasty is one of the most common and challenging cosmetic procedures. One of the complications of rhinoplasty associated with dissatisfaction is nasal obstruction, which is often due to narrowing of the nasal valve area. Application of certain procedures such as turbinoplasty can prevent and correct this problem. This study aim was to investigate the effect of inferior turbinoplasty in red...

A hysteresis effect in the pressure/flow rate relationship of nasal breathing has frequently been observed in clinical tests and in lab investigations. Explanations that have been given in the literature are missing a fluid mechanic storage effect coming into play in reciprocating flows. This effect depends primarily on the way the rhinomanometric measurements are set up and not so much on the ...

OBJECTIVES Rhinomanometry is a widely accepted method for objective assessment of nasal patency. However, few studies have reported the values of otherwise healthy population for nasal resistance in East Asians. The purpose of this study was to measure normal total nasal resistance (TNR) values in a large sample of Korean adults and to reveal parameters contributing to TNR values. METHODS Sub...

The letter by Garcia et al. raised a concern that the reported correlation between computational fluid dynamics (CFD)-simulated and rhinomanometry-measured nasal resistance (NR) in our recent article is smaller than expected, although is still statistically significant (r5 0.41, P< 0.01). This concern appears unwarranted given that this is the first published comparison between CFD simulations ...

The change in airway resistance along the nasal passage can be determined by passing a pressure sensing cannula carefully along the passage and determining the pressure-flow relationships during quiet breathing (Bridger and Proctor, 1970). Using this technique, Haight and Cole (1983b) clearly demonstrated that the major site of nasal resistance lies at the anterior end of the inferior turbinate...
