Management of Airway in patients with complex maxillofacial trauma is challenging due to disruption of components of upper airway. Submental intubation is a simple, quick and effective alternative to oral and nasal intubation or tracheostomy.This provides a secure airway and allows unimpeded surgical access to the oral cavity and midface, whilst avoiding the potential complications associated w...

introduction adenotonsillar hypertrophy is a common disorder among children which, without proper treatment, may lead to considerable problems. although the consequences of this disorder have been studied in other articles, we decided to evaluate the changes in pulmonary function tests in these children after adenotonsillectomy, and the correlation between clinical and spirometric parameters.  ...

Background: Potassium permanganate (PP) is a highly corrosive and deadly agent with a reported lethal dose of 10 g in adults. In this report, successful treatment of a patient poisoned with three times the lethal dose of PP is presented, and effective and early approach to such emergency toxicologic condition is discussed. Case Presentation:A 24-year-old woman presented to emergency room of our...

Healthy subjects with normal nasal resistance breathe almost exclusively through the nose during sleep. This study tested the hypothesis that a mechanical advantage might explain this preponderance of nasal over oral breathing during sleep. A randomised, single-blind, crossover design was used to compare upper airway resistance during sleep in the nasal and oral breathing conditions in 12 (seve...

Otolaryngologists are being asked with increasing frequency to assess adequacy of the upper airway and to treat upper airway obstructive problems in orthodontic patients. The incentive has been provided by recent studies that purport to relate upper airway obstruction to dental and craniomorphologic changes. It is hypothesized that prolonged oral respiration during critical growth periods in ch...

Obstructive sleep apnea (OSA) is common and is associated with a number of adverse outcomes, including an increased risk for cardiovascular disease. Typical treatment approaches, including positive airway pressure, oral appliances, various upper airway surgeries, and/or weight loss, can improve symptoms and reduce the severity of disease in select patient groups. However, these approaches have ...

background and objective: numerous anatomical abnormalities or pathological conditions can cause upper airway obstruction in obstructive sleep apnea syndrome (osas). muller’s maneuver (mm) is one of diagnostic modalities investigating the obstruction site in patients with osas. this study aimed to investigate the obstruction sites of patients with osas based on mm. materials and methods: this w...

BACKGROUND There are no prospective studies that evaluated airway changes during labor. The purpose of this study was to evaluate airway changes in women undergoing labor and delivery. METHODS Two studies were undertaken to evaluate airway changes during labor. The first study used the conventional Samsoon modification of the Mallampati airway class. The airway was photographed at the onset a...

Obstructive sleep apneasyndrome (OSAS) is a common chronic disorder (with a prevalence of about 2-4%) characterized by repetitive episodes of breathing cessation due to complete or partial collapse of the upper airway therefore affecting ventilation. If untreated, OSAS can lead to significant neurological problems (such as stroke, cognitive decline, depression, headaches, peripheral neuropathy,...
