the effects of disclosure of sequential Rhinomanometry scores on post septoplasty subjective scores of nasal obstruction a randomised controlled trial
Clinical Otolaryngology, 2012Co-Authors: Dubravko Manestar, Tamara Braut, Goran Malvic, Milodar Kujundžic, M Velepic, Donadic I Manestar, Matanic D Lender, Radan StarcevicAbstract:Clin. Otolaryngol. 2012, 37, 176–180 Objective: We sought to evaluate the effects of awareness of rhinomanometric results on subjective sensation of nasal breathing in patients after septoplasty. Design: Prospective randomised study. Setting: Clinical Hospital Rijeka. Participants: A study of 60 patients (45 M, 15 F) who underwent septoplasty was performed at the ENT Clinic, Clinical Hospital Rijeka. The patients were randomised into two groups; group A was shown their Rhinomanometry scores at 3 months postoperatively, while group B remained unaware of their Rhinomanometry results. Main outcome measure: The assumption is that in the same settings patients aware of their rhinomanometric results have better performances of their Nasal Obstruction Symptom Evaluation (NOSE) scale and thereby a better quality of life (QOL) after septoplasty. Results: The differences in rhinomanometric results and NOSE scale prior and after septoplasty were statistically significant (P < 0.001), all patients achieving better results after the operation. There was no statistically significant difference in resistance (F = 0.004; P = 0.948) and improvement of Rhinomanometry results in postoperative measurements (F = 0.110; P = 0.896) between groups A and B. The symptoms measured by the NOSE scale were the same in both groups preoperatively and 1 month after septoplasty (F = 2.906; P = 0.094). Three months postoperatively in group A, the NOSE scale score was lower (M = 11.67; sd = 12.34) than in group B (M = 27.50; sd = 18.04). Conclusions: The results suggest that disclosing information to patients about their post-septoplasty Rhinomanometry results may improve subjective nasal breathing, and thus improve their QOL.

the significance of Rhinomanometry in evaluation of postlaryngectomy olfactory rehabilitation by polite yawning technique
Rhinology, 2011Co-Authors: Dubravko Manestar, Robert Ticac, Marko Velepic, Tamara Braut, I Manestardonadic, Koraljka Manestar, Goran Malvic, Radan StarcevicAbstract:Objective was to corroborate the result of postlaryngectomy olfactory rehabilitation evaluating the efficacy of the Polite Yawning Technique (PYT) with Rhinomanometry and odours with the Smell diskettes Olfaction test (SDOT). Thirty-two laryngectomised patients were subjected to olfactory rehabilitation consisting of 15-minute training and independent exercising for two weeks. The sense of smell and nasal airflow in laryngectomised patients were examined before and after implementation of PYT. The differences in SDOT results prior to and after introduction of PYT were statistically significant, most patients achieving better results after rehabilitation. A significant positive correlation was obtained in results of SDOT and Rhinomanometry prior to and after introduction of PYT. The results of measurements after rehabilitation showed that 75% of patients had improved nasal breathing, 78% of patients had a better sense of smell and 40% of patients became normosmic. PYT has proved to be an effective method in olfaction rehabilitation following total laryngectomy. Using Rhinomanometry, evaluation of the rehabilitation success is substantiated while the technique is simplified.

acoustic rhinometry compared with anterior Rhinomanometry in the assessment of the response to nasal allergen challenge
Clinical Otolaryngology, 1994Co-Authors: G K Scadding, Y C Darby, C E AustinAbstract:Acoustic rhinometry was used to assess nasal airway patency objectively and was compared with the more established method of anterior Rhinomanometry. Ten patients with allergic rhinitis underwent 15 nasal challenges with allergen to which they showed positive skin-prick tests. Responses were assessed by measuring the minimum nasal cross-sectional area (Amin.) using acoustic rhinometry and by measuring nasal airway resistance (NAR) using anterior Rhinomanometry. The measurements of Amin. and NAR showed a significant negative correlation. Acoustic rhinometry appears to be superior to anterior Rhinomanometry in quantifying the response to nasal allergen challenge and may be particularly useful in patients with initial nasal blockage.

acoustic rhinometry compared with posterior Rhinomanometry in the measurement of histamine and bradykinin induced changes in nasal airway patency
British Journal of Clinical Pharmacology, 1994Co-Authors: C E Austin, J C ForemanAbstract:Abstract 1. Acoustic rhinometry is a relatively new method for objectively assessing nasal airway patency. In this paper we compare acoustic rhinometry with active posterior Rhinomanometry. 2. Twenty normal healthy volunteers underwent nasal challenge with either histamine or bradykinin, 100 micrograms to 1000 micrograms, and responses were assessed by acoustic rhinometry. A further 20 subjects received identical nasal challenges and responses were assessed by active posterior Rhinomanometry. 3. On a subsequent occasion, the subjects challenged previously with histamine, were given the selective H1-receptor antagonist, cetirizine, 10 mg orally, 3 h before repeat nasal challenge with histamine, 100-1000 micrograms. Again, responses were assessed by active posterior Rhinomanometry and acoustic rhinometry. 4. The acoustic reflection measurements and the nasal airway resistance measurements showed comparable, significant dose-related changes in nasal patency to both histamine and bradykinin. Pretreatment with cetirizine blocked the histamine-induced change in nasal patency as measured by both methods. 5. We conclude that acoustic rhinometry has a number of advantages over posterior Rhinomanometry. It is quick to perform, requires minimal subject co-operation and gives a reliable objective, measurement of dose-related changes in nasal airway patency before and after pharmacological treatment.

protruding the tongue improves posterior Rhinomanometry in obstructive sleep apnoea syndrome
European Respiratory Journal, 1999Co-Authors: Andre Coste, Frederic Lofaso, M P Dortho, Bruno Louis, Estelle Dahan, R Peynegre, A HarfAbstract:In posterior Rhinomanometry (PRM), oropharyngeal pressure is measured using a tube placed between the tongue and the hard palate. For valid results the patient must position the tongue and soft palate so that both the oropharynx and nasopharynx remain open. A high rate of failure of conventional PRM has been reported in normal individuals. In patients with obstructive sleep apnoea syndrome (OSAS), upper airway abnormalities may further increase the failure rate. This study proposes a modification of the technique in which protrusion of the tongue enhances pressure transmission between the nasopharynx and the mouth. In eight normal subjects, resistance was similar when measured by both methods. Of 24 OSAS patients, conventional PRM was unsuccessful in 11. In the remaining 13 patients, a significant correlation between the two methods was found, but resistance was lower by "tongue-out" than by conventional PRM, consistent with a decrease, during tongue protrusion, in retropalatal resistance, which is a component of the "nasal" resistance measured by PRM. In 26 OSAS patients, unilateral nasal resistance values measured by "tongue-out" PRM were similar to those measured by anterior Rhinomanometry. When the "tongue-out" method was used routinely in 541 snorers, failure rates were 1.1% in the 272 non-OSAS patients and 3.7% in the 269 OSAS patients. These results indicate that posterior Rhinomanometry with tongue protrusion is a highly effective tool for measuring nasal resistance in snorers.

can we always trust Rhinomanometry
Rhinology, 2011Co-Authors: Helle L Thulesius, Anders Cervin, Max JessenAbstract:Objectives: Rhinomanometry before and after decongestion distinguishes a nasal airway organic stenosis from congestion of nasal mucosa in patients with nasal stuffiness. Together with rhinoscopy and patient history, it is used to decide if nasal surgery would benefit the patient. Rhinomanometry measurements should thus be reliable and reproducible. Materials and methods: We performed repetitive active anterior Rhinomanometry in 9 persons during 5 months to test reproducibility of nasal airway resistance (NAR) over time. We also did test-retest measurements in several participants. Xylometazoline hydrochloride was applied in each nasal cavity to minimize effects of mucosal variation and the nasal cavity was examined with rhinoscopy. The participants evaluated subjective nasal stuffiness on a visual analogue scale (VAS). Results: The long term mean coefficient of variation (CV) of NAR over time was 27% for the whole group while the short term CV was 7 - 17% for test-retest within an hour. Mean NAR reduction after decongestion was 33%, but 13% of NAR values were not reduced after decongestion. Participants had difficulties estimating stuffiness on a VAS in 15% of the assessments, but there was no correlation between the VAS estimates and NAR. Conclusion: We found a high NAR variation over a period of five months. This implies low long-term Rhinomanometry reproducibility and we suggest future research on standardised decongestion to increase the reproducibility.

responsiveness of acoustic rhinometry to septorhinoplasty by comparison with Rhinomanometry and subjective instruments
Clinical Otolaryngology, 2019Co-Authors: Edward Ansari, Florence Rogister, Philippe Lefebvre, Sophie Tombu, Annelise PoirrierAbstract:OBJECTIVES: Nose patency measures and instruments assessing subjective health are increasingly being used in rhinology. However, there is very little evidence of comparing existing methods' responsiveness to change. We evaluated the responsiveness of acoustic rhinometry to nasal valve surgery by comparison with Rhinomanometry and patient-reported outcome instruments. DESIGN: Prospective case-control study. SETTING: Tertiary referral University Hospital. PARTICIPANTS: Sixty consecutive patients with internal nasal valve dysfunction and 20 healthy volunteers as control group were enrolled. Prospectively collected data included acoustic rhinometry, Rhinomanometry, NOSE scale, SNOT-23 questionnaire, visual analogue scale and demographics. MAIN OUTCOME MEASURES: Primary endpoint was the responsiveness of acoustic rhinometry to functional septorhinoplasty surgery at 3 months. Secondary endpoints were ability of acoustic rhinometry to reflect "known group" differences and correlation to subjective symptoms. RESULTS: Acoustic rhinometry was highly responsive to septorhinoplasty (P < 0.0001) while anterior Rhinomanometry was not (P = 0.08). Based on the quartiles of the postoperative change in NOSE score, patients were classified as, respectively, non-responders, mild, moderate and good responders to surgery. Logistic regression model showed that acoustic rhinometry was able to discriminate non-responders to responders to surgery (P = 0.019), while anterior Rhinomanometry failed (P = 0.611). Sensitivity and specificity of acoustic rhinometry were significantly higher (ROC area = 0.76) than Rhinomanometry (ROC area = 0.48). Acoustic rhinometry was also superior than Rhinomanometry to discriminate patients from control subjects and agreed better with patients-based subjective questionnaires. CONCLUSIONS: Our study confirms and quantifies the responsiveness of acoustic rhinometry to nasal valve surgery, with a higher sensitivity and specificity than Rhinomanometry.
