The ventilatory controlling factors associated with oral augmentation of nasal breathing were investigated in 25 (14 women, 11 men) healthy adults during an incrementally graded bicycle exercise test. Ventilatory variables were measured by separate oral and nasal pneumotachometers integrated with a valveless oral-nasal face mask and a flexible oral catheter. Inspired and expired breath length, ...

The nasal cavity volume and the temperature of the nasal mucosa are considered to be the most important predictors of nasal conditioning. The aim of this study was to assess the relationship between the intranasal degree of water vapour saturation of inhaled air and nasal patency. Intranasal humidity values at different locations within the nasal cavity of 15 healthy subjects were compared to n...

One of the simple and economical diagnostic methods in detecting nasal allergic disorders is cytological examination of nasal smears. This study was conducted to evaluate the usefulness of nasal cytology in individuals suffering from allergic nasal disorders, including allergic nasal polyps with special interest on cytohistological correlation in case of allergic nasal polyps. Effort is also ma...

In this study, we analyze and discuss the treatments of postoperative nasal complications after endonasal transsphenoidal resection of pituitary neoplasms (PNs). We performed 129 endonasal transsphenoidal resections of PNs and analyzed and treated cases with nasal complications. After endonasal transsphenoidal resection of PNs, there were 26 cases of postoperative nasal complications (20.1%), i...

Although there is a strong correlation between oral/oro-nasal breathing and apnoea/hypopnoea index in patients with obstructive sleep apnoea and normal nasal resistance at wakefulness, it remains unknown whether the pharmacological prevention of potential nasal obstruction during sleep could decrease oral/oro-nasal breathing and increase nasal breathing and subsequently decrease the apnoea/hypo...

Nasal hyperreactivity in nasal allergy conditions is closely related to allergic inflammation, particularly to infiltration by activated eosinophils in the nasal mucosa, observed 4 to 10 hours after a single antigenic challenge. Repeated antigenic challenge in subjects with nasal allergy enhanced nasal hyperreactivity. On the other hand, various therapies including topical steroids, immunothera...

a 45 year old farmer from espand village (located in the west of iranshahr county, sistan and baluchistan province, southeastern of iran) with some clinical manifestations referred to the khatam-al-anbia hospital in the city of iranshahr. ct scan showed an extensive edema in nasal and para nasal sinuses. endoscopy consideration revealed the presence of numerous larvae lodged inside the nasal ca...
