BACKGROUND The efficacy of delivery of mechanical ventilation through different airway devices during fibreoptic intubation is not known. METHODS We compared the laryngeal mask airway (LMA), intubating laryngeal mask (ILM) and endoscopy mask for positive pressure ventilation (PPV) during fibreoptic intubation. In 80 adult paralysed patients, fibreoptic intubation was performed during PPV usin...

BACKGROUND Epistaxis is the most common complication of nasotracheal intubation. We compared endotracheal tubes (ETT) obturated with an inflated esophageal stethoscope with normal ETTs with regard to the prevention of epistaxis and navigability, both with and without thermosoftening. METHODS Dental surgical patients requiring nasotracheal intubation were randomly allocated into 1 of 4 groups ...

STUDY OBJECTIVES The present study introduces a method that has been developed to improve the remote collection and transportation of gas samples from the nose and lungs. DESIGN Assessment of agreement between two methods of clinical measurements. SETTING Noninvasive exhaled gas measurement at a respiratory research laboratory. PARTICIPANTS Ten nonsmoking adult volunteers (median age, 44 ...

the main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. due to the above mentioned problems and in order to solve and minimize them nasal packing, na...

introduction rhinoliths are uncommon nasal masses. they are mineralized masses found within the nasal cavity. they have various clinical presentations. case presentation we report a 13-year-old boy with long-standing nasal obstruction, yellowish nasal discharge and intermittent and minimal nasal bleeding for a few weeks, who had been treated as rhinosinusitis twice. due to the presence of long-...

in crooked noses, the lateral walls are different in shape and symmetry. although the septum is very important to obtain a straight nose, identical and symmetrical lateral walls are needed for a straight looking nasal dorsum. as well as the septum, lateral walls also contribute in nasal skeletal support and stability. thus, obtaining identical and symmetrical lateral walls is important. in orde...

Patients requiring emergency airway management may be at greater risk of acute hypoxemic events because of underlying lung pathology, high metabolic demands, insufficient respiratory drive, obesity, or the inability to protect their airway against aspiration. Emergency tracheal intubation is often required before complete information needed to assess the risk of procedural hypoxia is acquired (...

Local cooling of the brain by the respiratory air is found in many animal species. The mechanism is based on cooling of the nasal vein blood and heat transfer in the cavernous sinus/carotid artery complex and is therefore not active in anaesthetised, intubated animals. The present experiment was made to investigate the effects of oxygen flushing of the nasal cavities in such animals. Nine anaes...

Rhinoscleroma is a chronic granulomatous infection of the upper respiratory tract, particularly affecting the nose. It is a bacterial disease mainly caused by rhinoscleromatis subspecies of Klebsiella pneumoniae. We described a case of a 72-year-old Chinese man presented with repeated epistaxis for more than 2 years without any inducing factors accompanied by nasal obstruction, purulent dischar...

Objective. Adenoid curette guided by an indirect transoral mirror and a headlight is a simple and quick procedure that has already been in use for a long time, but this method carries a high risk of recurrence unless done by a well-experienced surgeon. The purpose of this paper was to evaluate the efficacy of transoral endoscopic adenoidectomy in relieving the obstructive nasal symptoms. Method...
