Effects of the Breathe Right Nasal Strips on Nasal Ventilation
1997
The Breathe Right nasal strips are more and more commonly used, mainly by athletes, who hope to enhance their physical performance in competition and training. The effect of the device in such situations is uncertain and perhaps somewhat controversial. To investigate the effects of the nasal strips on nasal ventilation, 20 Caucasian individuals were objectively assessed using anterior rhinomanometry and acoustic rhinometry. The results showed a significant increase in all subjects of transnasal airflow and in the average cross-sectional area of the nasal cavity that quantifies objectively the subjective impression of improved nasal breathing. In such patients where an improvement in nasal …
Differences and Similarities between Allergic and Nonallergic Rhinitis in a Large Sample of Adult Patients with Rhinitis Symptoms
2010
<i>Background:</i> Allergic rhinitis (AR) and nonallergic rhinitis (NAR) may present with different clinical and laboratory characteristics. <i>Methods:</i> A total of 1,511 consecutive patients, aged 18–81 years, diagnosed with rhinitis, 56% females and 44% males, underwent complete allergic evaluation including skin prick test, blood eosinophil counts, nasal eosinophil counts, peak nasal inspiratory flow (PNIF) measurement and evaluation of nasal symptoms using a visual analog scale (VAS). <i>Results:</i> A total of 1,107 patients (73%)had AR, whereas 404 (27%) had NAR. Patients with NAR were older and predominantly female. A higher nasal eosinophils co…
Pleomorphic adenoma of the lateral nasal wall: case report.
2008
Pleomorphic adenoma is the most common tumour of the salivary glands. However, it is extremely rare for these to originate in the nose and even when they do so, it is most commonly in the nasal septum. It is important to be aware of the paucity of presenting symptoms (nasal obstruction and epistaxis), as the lesion may not be recognized immediately. Growth is generally restricted locally and the tumour is not known to spread to the neighbouring structures. Surgical resection is the treatment of choice. Recurrences and evolution to malignancy are not frequent, but long-term follow-up is recommended. The case is presented of pleomorphic adenoma arising from the lateral wall of the right nasal…
Radiofrequency, high-frequency, and electrocautery treatments vs partial inferior turbinotomy: microscopic and macroscopic effects on nasal mucosa.
2009
Objective To compare the microscopic and macroscopic effects of radiofrequency, high-frequency, and electrocautery therapies with partial inferior turbinotomy in the treatment of nasal obstruction caused by inferior turbinate hypertrophy. Design Nonrandomized controlled trial. Setting Department of Otolaryngology–Head and Neck Surgery, University of Genoa. Patients The study included 80 patients affected by nasal obstruction from hypertrophied inferior turbinates. Interventions Homogeneous patient groups A, B, C, and D underwent radiofrequency, high-frequency, and electrocautery treatments and partial inferior turbinotomy, respectively, to surgically reduce hypertrophied inferior turbinates…
Effect of irrigation of the nose with isotonic salt solution on adult patients with chronic paranasal sinus disease
2001
In a prospective, randomized, controlled, double-blind trial we compared the effectiveness of endonasal irrigations with Ems salt solution to that with sodium chloride solution in the treatment of adult patients with chronic paranasal sinus disease. Subjects (n = 40) were randomly allocated to treatment either with isotonic Ems salt solution or with isotonic sodium chloride solution. The treatment consisted of endonasal irrigation twice daily and additional nasal spray as required. Nasal endoscopy, plain radiography of the paranasal sinuses, olfactometry, anterior rhinomanometry, and a saccharin-clearance test were carried out on days 1 and 7. Patients recorded rating scales of general disc…
Nasal airway in cleft-palate patients: acoustic rhinometric data
1997
The objective of this study was to investigate an instrumental assessment technique for acquiring reproducible, metric data on the nasal airway in cleft-palate associated nasal dysplasia. A consecutive sample of 23 unilateral, 17 bilateral CLP patients and 15 controls with subjective normal nasal patency from a cleft-palate rehabilitation centre were studied. A series of transnasal acoustic measurements (pressure wave: 55 dB for 2 ms) of nasal volume were performed before and after topical decongestion with 2 x 0.3 mg of xylometazoline. A standardized regimen of acoustic parameters of the nasal valve and the adjacent segment of the nasal cavity were calculated. The cleft side yielded a sign…
Four-phase rhinomanometry: a multicentric retrospective analysis of 36,563 clinical measurements
2015
Rhinomanometry can still be considered as the standard technique for the objective assessment of the ven- tilatory function of the nose. Reliable technical requirements are given by fast digital sensors and modern information technology. However, the xyimaging of the pressure-flow relation typically shows loops as a sign of hysteresis, with the need for resolution of the breath in four phases. The three pillars of 4-phase rhinomanometry (4PR) are the replacement of estimations by measurements, the introduc- tion of parameters related to the subjective sensing of obstruction, and the graphical information regarding the disturbed function of the nasal valve. In a meta-analysis of 36,563 clini…
Acoustic Airway Profiles in Unilateral Cleft Palate Patients
1999
Objective: This study investigates the nasal airway in unilateral cleft palate patients by means of a noninvasive, objective diagnostic method that provides topographic information about the airway profile. Design: A consecutive sample of patients was measured. Setting: Cleft palate rehabilitation center of the University of Mainz, Germany. Patients: Forty-nine subjects were investigated: 34 full-grown patients with complete unilateral cleft lip and palate and 15 controls with subjective normal nasal patency. Intervention: A transnasal series of three acoustic measurements of nasal volume was performed per nostril; measurements were taken both before and after decongestion with 0.3 mg xylom…

In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differ…
