IMPLICATIONS Two patients experienced partial upper airway obstruction while breathing spontaneously with the ProSeal laryngeal mask airway. This resulted in esophageal aspiration of air through the drain tube.

BODY: Introduction: Obstructive sleep apnea (OSA) is a common sleep disorder affecting both men and women in all ethnicities. It is well known that the primary cause of OSA is upper airway obstruction due to either anatomical or neurologic factors. The primary treatment modality for OSA is Continuous Positive Airway Pressure (CPAP). However, a significant proportion of patients diagnosed with O...

Negative pressure pulmonary edema is a potentially life-threatening condition that may occur when a large negative intrathoracic pressure is generated against a 'physically' obstructed upper airway during emergence from anesthesia. We report a 35 year old male patient who is morbidly obese and undergoing laparoscopic gastric bypass who developed negative pressure pulmonary edema without any evi...

Retropharyngeal abscess with involvement of mediastinal abscess represents an uncommon complication of upper respiratory tract infections. We report a case presenting with a large retropharyngeal abscess with airway obstruction as the primary presenting symptom. Contrast-enhanced CT showed a large retropharyngeal abscess in the neck with extension to the upper and posterior mediastinal spaces. ...

Congenital nasal pyriform aperture stenosis (CNPAS) is a recently defined clinical entity that causes airway obstruction in the neonate as a result of narrowing of the nasal pyriform aperture. The pyriform aperture is the narrowest, most anterior portion of the nasal airway, and a slight decrease in its cross sectional area will significantly increase the nasal airway resistance. This entity sh...

Predominance of low AHI and partial upper airway obstruction may lead to undertreatment of female SDB http://ow.ly/TKN7d.

OBJECTIVE Benign nodular goiter (BNG) can cause narrowing of the upper airway. In some rare cases, obstruction of the upper airway also occurs. The following paper reports our experiences with regard to BNG patients who experienced obstruction of the upper airway. MATERIALS AND METHODS We retrospectively investigated the records of 13 patients with acute airway obstruction due to BNG who were...

OBJECTIVES To document the causes of upper airway obstruction in a population of children with Down syndrome and to highlight the role of associated comorbidities. DESIGN AND SETTING Review of 23 cases involving children with Down syndrome who were referred for upper airway obstruction over a 2(1/2)-year period to the Pediatric Otolaryngology Service of the University of New Mexico, Albuquerq...

UNLABELLED Children with enlarged tonsils and adenoids usually present breathing abnormalities such as snoring, mouth breathing and sleep apnea. It is known that upper airway obstruction and consequent mouth breathing may result in pulmonary diseases. AIM The goal of this preliminary study was to evaluate the inspiratory pressure in children with upper airway obstruction due to enlarged tonsi...
