Some aerodynamic approaches to the estimation of velopharyngeal opening (VPO) are confounded by oral impedance, which varies with tongue height and affects nasal flow. Here the relationship between nasal flow and tongue height is investigated using a synchronized EMAaerodynamics system. A corpus of Hindi nasal and oral vowels is examined. Tongue height and nasal flow are weakly but positively c...

As the main mucosal immune inductive site of nasal cavity, nasal-associated lymphoid tissue (NALT) plays an important role in both antigen recognition and immune activation after intranasal immunization. However, the efficiency of intranasal vaccines is commonly restricted by the insufficient intake of antigen by the nasal mucosa, resulting from the nasal mucosal barrier and the nasal mucocilia...

OBJECTIVES We assessed the efficacy of different forms of fluticasone propionate in the treatment of bilateral nasal polyposis in adult patients. PATIENTS AND METHODS This double-blind, randomized, parallel group study included 34 patients, aged 16 years or over, with a diagnosis of bilateral nasal polyposis. The patients were randomized to three groups to receive fluticasone propionate in th...

background: fetal nasal bone assessment is a non-invasive procedure that helps provide even greater assurance to patients undergoing their first trimester risk assessment for aneuploidies. absence or presence of this factor is different in some races. objective: the study was aimed to evaluate nasal bone in the first trimester of pregnancy in the indigenous population of khuzestan province, and...

Nasal valve collapse is a primary cause of nasal obstruction. Patients with airway obstruction suffer from variety symptoms that affect quality life including congestion, headache, sleep problems, daytime sleepiness, and snoring.

Local Allergic Rhinitis (LAR) is an emerging disease. However, its incidence in the pediatric population has not yet been studied. The gold-standard for the diagnosis is the nasal provocation test that is not everywhere available and difficult to apply in children. The aim of our study is to evaluate the nasal lavage fluid IgE as a biomarker of LAR in children. 54 pediatric patients [IQR 4.0-12...

Introdouction: The mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. The position of objects that create a ghost image can differ when using various devices. The purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a Cranex D digital panoramic machine. Materials and methods: ...

OBJECTIVES To find if the presence of epistaxis after nasal trauma can be used to predict post-traumatic external nasal deformity or a symptomatic deviated nasal septum. METHODS Retrospective analysis of all patients seen in the fractured nose clinic by the first author between 17 October 2003 and 27 February 2004. Presence of epistaxis, newly developed external nasal deformity, and the prese...

Introduction: Olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable, and it is not clear whether endoscopic sinus surgery significantly improves olfactory function. This study was performed to evaluate the influence of endoscopic sinus surgery on olfactory function in patients with chronic rhinosinusitis.  Material...

The aim of the present study was to determine if nasal massage of the yingxiang acupuncture point in patients with nasal congestion associated with perennial nasal allergy had any effect on nasal airway resistance (NAR) measured by anterior rhinomanometry and sensation of nasal airflow on a visual analogue scale (VAS). Ten patients were recruited for this study. NAR and VAS were measured before...
