BACKGROUND Simple snoring represents a social problem, not only because it could affect the patient's married life, but it often goes along with sleep-disordered breathing. Chronic nasal obstruction has many sequel including snoring and the inferior turbinate hypertrophy (ITH) is its most common cause. The aim of the study is to evaluate the efficacy of video-assisted endoscopic radiofrequency ...

Rhinoliths are mineralised foreign bodies in the nasal cavity that are a chance finding at anterior rhinoscopy. Undiscovered, they grow appreciably in size and can cause a foul-smelling nasal discharge and breathing problems. Giant nasal stones are now a very rare occurrence, since improved diagnostic techniques, such as endoscopic/microscopic rhinoscopy, now make it possible to identify foreig...

BACKGROUND/AIM Hypoxia and carbon dioxide rebreathing are potential problems during eye surgery in spontaneously breathing patients. The aim of the present study was to determine effectiveness of nasal application of oxygen to prevent hypoxia and carbon dioxide accumulation in spontaneously breathing patients undergoing cataract surgery. METHODS Oxygenation and carbon dioxide rebreathing were...

Electrical stimulation of an epibranchial vagal ganglion, which innervates the gill region, had a marked influence on the respiratory rhythm of the carp Cyprinus carpio. Vagal input could initiate ventilation in fish displaying intermittent respiration. In fish breathing steadily, vagal stimuli could reset the respiratory rhythm by modifying the existing breathing cycle. An increase of stimulus...

OBJECTIVES To detail empty nose syndrome (ENS), an iatrogenic disorder characterized by a patent airway but a subjective sense of poor nasal breathing, and to explore repair options for patients with ENS. DESIGN A case series of 8 patients with ENS detailing symptoms before and after submucosal implantation of acellular dermis. SETTING Academic medical center. PATIENTS Subjects who were e...

BACKGROUND Open mouthpiece ventilation is efficacious in patients with neuromuscular disease. We used this ventilation technique in patients with exacerbations of COPD with mild to moderate acidosis. METHODS The study was performed in 2 respiratory monitoring care units. Fifty subjects with exacerbations of COPD, breathing frequency > 25, PaCO2 > 45, and pH between 7.25 and 7.30, as well as K...

To determine the combined effect of increased subatmospheric upper airway pressure and withdrawal of phasic volume feedback from the lung on genioglossus muscle activity, the response of this muscle to intermittent nasal airway occlusion was studied in 12 normal adult males during sleep. Nasal occlusion at end expiration was achieved by inflating balloon-tipped catheters located within the port...

PURPOSE To compare the hard palate dimensions of nasal-breathing children, mouth breathers from obstructive etiology, and habitual mouth breathers. METHODS The sample comprised 76 children, 37 boys and 39 girls, with mean age of 9.32±1.16 years, distributed according to the diagnosis of breathing mode and to the etiology of mouth breathing. Plaster cast models of the subjects' superior dental...

The prevalence of reported sleep disturbances in a general population is high. Many of the complaints are the result of sleep-related breathing disorders, due mainly to the occurrence of obstructive and central apnoeas. Obstructive sleep apnoea is a fully described and well-recognized entity. Central sleep apnoea (CSA) however, has been poorly studied. There is accumulating evidence that centra...
