rhinomanometry

Obstructive sleep apnea (OSA) patients who use continuous positive airway pressure (CPAP) often complain of nasal dryness and nasal obstruction as side effects of CPAP. The physiological mechanisms by which CPAP may cause nasal dryness and nasal obstruction remain poorly understood. It has been hypothesized that CPAP interferes with the nasal cycle, abolishing the resting phase of the cycle and leading to nasal dryness. We performed rhinomanometry measurements in 31 OSA patients sitting, laid supine, and supine after 10minutes of CPAP at 10 cmH2 O...

Computational rhinology is a specialized branch of biomechanics leveraging engineering techniques for mathematical modelling and simulation to complement the medical field of rhinology. Computational rhinology has already contributed significantly to advancing our understanding of the nasal function, including airflow patterns, mucosal cooling, particle deposition, and drug delivery, and is foreseen as a crucial element in, e.g., the development of virtual surgery as a clinical, patient-specific decision support tool...

BACKGROUND: Nasal airway stenosis may lie anterior and/or posterior to the piriform aperture. We intended to compare the nasal airway anterior and posterior to the piriform aperture in patients with and without nasal obstruction. METHODS: Segmented computed tomography cross-sectional areas of the nasal airway anterior (CT-CSAant ) and posterior to the piriform aperture (at the level of the head of the inferior turbinate; CT-CSApost ) were compared between patients with nasal obstruction (cases) and trauma controls...

BACKGROUND: This study aimed to determine how nasal airflow measures and trigeminal function vary among patients with chronic rhinosinusitis (CRS) versus healthy controls and whether these measures are correlated with subjective nasal obstruction (SNO), olfactory function, and CRS control. METHODOLOGY: Participants included CRS patients and healthy controls. After a structured medical history, nasal airflow (peak nasal inspiratory flow [PNIF]; active anterior rhinomanometry [AAR]), trigeminal function (trigeminal lateralization test, CO2 sensitivity), and olfactory ("Sniffin' Sticks" odor identification test) tests were performed...

Background: Hyaluronic acid (HA), the main component of the extracellular matrix, has the ability to promote tissue repair and regulate inflammation. It is used in otolaryngology as an adjuvant treatment to alleviate postoperative nasal symptoms. However, there is currently insufficient evidence demonstrating the therapeutic efficacy of HA for patients with nasal inflammatory diseases (NIDs). Therefore, this study aimed to evaluate the efficacy and safety of topical HA in the treatment of NID patients without receiving surgery...

PURPOSE: Nowadays, several efficacious biologic drugs are used for severe asthma with or without chronic rhinosinusitis with nasal polyps (CRSwNP). However, it has been observed that not all comorbid patients (asthma/CRSwNP) receiving biologic treatment for asthma experience satisfactory control of both conditions equally. METHODS: We selected 20 patients who had both severe asthma and comorbid CRSwNP under biological treatment with benralizumab, omalizumab or mepolizumab with adequate control of asthma but inadequate control of nasal symptoms...

Rhinoresistometry (RRM) is implemented along with active anterior rhinomanometry (AAR) and can evaluate nasal dimensions [hydraulic diameter (HD)]. As acoustic rhinometry (AR) is time-consuming, the authors investigated if RRM can be an efficient alternative to AR in nasal dimension assessment in orthognathic surgery. In patients undergoing maxillary advancement and impaction (cases) and removal of maxillary cysts (controls), the authors evaluated RRM and AR, before and 1 year after surgery. Furthermore, the authors investigated the correlation of HD with Nasal Obstruction Symptom Evaluation score and volume by computed tomography and AAR...

'Elastometry' is a novel technique that allows for the quantitative assessment of elastic properties of the nasal tissues, providing valuable insights into the dynamic behavior of the external, soft lateral nasal wall. This study aimed to explore the application of 'elastometry' in understanding the biomechanics of the lateral nasal wall and its implications for nasal function in 'elastometry' measurements. After validation of safety and reliability of this method, we investigated mechanical properties of the lateral nasal wall by 'elastometry' using specifically developed measurement forceps with end pieces including sensors applied on 30 healthy volunteers, aged 18 to 82 without a history of severe trauma or surgery...

Measuring nasal obstruction should be mandatory before every nasal surgery to determine necessary surgical steps and to separate the mucosal congestion from the skeletal deformity. Rhinomanometry is considered the "Golden Standard" for measuring the nasal airway resistance. An extension of the diagnostic power was achieved by the introduction of 4-phase-rhinomanometry 4PR, which does not only allow an additional information about the influence of the elasticity of the nasal wall. By introduction of logarithmic parameters also a high correlation to the subjective sensing of obstruction could be achieved...

Nasal obstruction is one of the main symptoms of different nasal pathologies. Many physiologic and pathologic conditions can produce nasal airflow impairment causing nasal obstruction and affecting patients' quality of life. There are different methods for the measurement of nasal obstruction, but in clinical practice the most common used are acoustic rhinometry, rhinomanometry and peak nasal inspiratory flow. This review describes the fundamental of acoustic rhinomanometry, its normal values, the different physiologic and pathologic conditions that can modify nasal patency and the utility of this instrument for the measurement of nasal obstruction in clinical practice...

Introduction: Radiotherapy causes significant nasal comorbidity in nasopharynx cancer (NPC) patients. However, the literature addressing the sino-nasal quality of life (QoL) of those patients, especially on structural and functional changes after radiotherapy, is limited.
