This occurs...

Nasal polyp causes difficulty in breathing due to blockage of nasal passage. The pathogenesis of nasal polyposis is not known. The primary medical therapy available for nasal polyposis is steroid administration. Antihistamines, decongestants and cromolyn sodium provide little benefit. With this background of nasal polyp pathophysiology and the existing management, a case of nasal polyp was trea...

Sleep-disordered breathing (SDB) includes a wide range of breathing difficulties during sleep from primary snoring to obstructive sleep apnea (OSA) and its estimated prevalence is from 0.9% to 13% in children.1 Repeated partial (flow limitation, hypopnea) or complete (apnea) airway obstruction and increased respiratory effort are usually observed in subjects with SDB and these disrupted breathi...

  Abstract:   Background: The most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. The differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. Caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. The...

Surgical interventions in the nasal cavity are accompanied by reactive phenomena in the postoperative period. On their background the process of physiological regeneration is disorganized resulting in impaired physiological functions of the nasal cavity. The objective of the research was to study the recovery process of the main physiological functions of the nasal cavity in patients with aspir...

Objective. To assess the outcomes of functional rhinoplasty for nasal valve incompetence and to evaluate an in-office test used to select appropriate surgical techniques. Methods. Patients with nasal obstruction due to nasal valve incompetence were enrolled. The modified Cottle maneuver was used to assess the internal and external nasal valves to help select the appropriate surgical method. The...

While nasal mucosal stimulation in animals has been reported to produce central apneas and while nasal packing in humans is known to produce sleep-disordered breathing, it is controversial whether intranasal obstruction in humans produces predominantly central or obstructive apnea. To answer this question, we studied eight normal men by having them sleep in random order with their nose open or ...
