Acoustic rhinometry, rhinomanometry, and the sensation of nasal patency: a correlative study.
ABSTRACT Acoustic rhinometry and rhinomanometry were used to evaluate the relationship between nasal cross-sectional areas, nasal resistances, and sensations of nasal patency. These parameters were measured before and after topical application of a nasal decongestant in 78 patients suffering from nasal obstruction. As subjects breathed voluntarily through both nasal cavities, no significant correlation was found between sensation of nasal patency and combined nasal minimum cross-sectional areas (r = .11) or of total airflow resistance (r = -.11) either before or after decongestion. However, when subjects were required to breathe through each nasal cavity separately, a significant correlation was found between ipsilateral sensation of nasal patency and both ipsilateral minimum cross-sectional area pre-decongestion (r = -.53, p < .0001) and post-decongestion (r = -.22, p < .01), and airflow resistance pre-decongestion (r = .42, p < .0001) and post-decongestion (r = .25, p < .01). A significant, negative, nonlinear relationship was also found between nasal minimum cross-sectional area and nasal resistance. Furthermore, acoustic rhinometry demonstrated that small intrusions into the lumen of the nose that might be missed by rhinoscopy produce an exponentially greater increase in nasal resistance measurements by rhinomanometry. The findings were most striking in the valve region. It is concluded that each of these objective and complementary measurement techniques provides a more reliable assessment of nasal patency than subjective evaluation by either patient or clinician and can thus provide valuable guidance in management of the symptom of nasal obstruction.
Article: Traditional Chinese Medicine ZHENG Identification Provides a Novel Stratification Approach in Patients with Allergic Rhinitis.[show abstract] [hide abstract]
ABSTRACT: Background. We aimed to apply the ZHENG identification to provide an easy and useful tool to stratify the patients with allergic rhinitis (AR) through exploring the correlation between the quantified scores of AR symptoms and the TCM ZHENGs. Methods. A total of 114 AR patients were enrolled in this observational study. All participants received the examinations of anterior rhinoscopy and acoustic rhinometry. Their blood samples were collected for measurement of total serum immunoglobulin E (IgE), blood eosinophil count (Eos), and serum eosinophil cationic protein (ECP). They also received two questionnaire to assess the severity scores of AR symptoms and quantified TCM ZHENG scores. Multiple linear regression analysis was used to determine explanatory factors for the score of AR manifestations. Results. IgE and ECP level, duration of AR, the 2 derived TCMZHENG scores of "Yin-Xu - Yang-Xu", and "Qi-Xu + Blood-Xu" were 5 explanatory variables to predict the severity scores of AR symptoms. The patients who had higher scores of "Yin-Xu - Yang-Xu" or "Qi-Xu + Blood-Xu" tended to manifest as "sneezer and runner" or "blockers," respectively. Conclusions. The TCM ZHENG scores correlated with the severity scores of AR symptoms and provided an easy and useful tool to stratify the AR patients.Evidence-based Complementary and Alternative Medicine 01/2012; 2012:480715. · 4.77 Impact Factor

ABSTRACT: Objective. To evaluate the changes in nasal dimensions of healthy Iranian volunteered for cosmetic rhinoplasty after surgery using acoustic rhinometry. Methods. Pre-and postoperative nasal dimension of 36 cases undergoing cosmetic rhinoplasty were compared using acoustic rhinometry (AR), and the measured variables were distance to first and second constriction (d1, d2), first and second minimal cross-sectional area (MCA1, 2), and volume. Results. Mean age (SD) of cases were 24.63 (4.4) years. Septoplasty was performed in 12 cases (33.3%). After surgery, bilateral d1 and both MCA2 decreased significantly, while significant increase was observed in MCA1 postoperatively using decongestant. Cases with septoplasty experienced more increase in MCA1 and less constriction in MCA2 postoperatively. In cases with rhinoplasty alone, they received benefit from double osteotomy in MCA1. In either group of rhinoplasty with and without septoplasty, placing a strut was beneficial for patients. Discussion. The cross-sectional area of the nose is a major factor in the determination of airflow. Cosmetic rhinoplasty may generate a mix effect on nose function. Performing osteotomy may better help patients to save nasal patency, septoplasty is beneficial even in mildly deviated septums, and placing a strut may be beneficial in most of the cases.ISRN Otolaryngology. 01/2011; 6.
