BACKGROUND: Infants and children with syndromic craniosynostosis (SCS), such as Apert-, Crouzon- or Pfeiffer syndrome, are prone to sleep disordered breathing (SDB) including obstructive sleep apnea and upper airway resistance syndrome (OSAS, UARS), potentially leading to tracheostomy. We modified the Tübingen Palatal Plate (TPP), an oral appliance with a velar extension effectively treating airway obstruction in Robin sequence, by attaching a tube to its velar extension to bridge the narrow pharyngeal airway in SCS patients...

Obstructive sleep apnoea (OSA) is characterised by recurrent upper airway collapse during sleep resulting in chronic and repetitive hypoxia, hypercapnia, subsequent arousal and fragmented sleep. Symptoms are insidious and diagnosis is usually delayed. Moderate to severe OSA has serious health implications with significant increase in all causes of mortality in patients with the condition as compared with unaffected individuals. The prevalence of OSA in the 30-70 year age group is estimated at 27% of males and 11% of females and it increases with age...

BACKGROUND: In the spectrum of children with symptomatic sleep disordered breathing (SDB), some individuals - such as those with upper airway resistance syndrome (UARS) - do not have abnormalities on polysomnography (PSG). In this study we have assessed whether assessment of respiratory arrhythmia (RA) and heart rate variability (HRV) analysis helps in management of children with syndromic craniosynostosis and none-to-mild obstructive sleep apnea (OSA). METHODS: Prospective cohort study in children aged 1-18 years old with syndromic craniosynostosis...

BACKGROUND: Implantable hypoglossal nerve upper airway stimulation (HNS) is a novel, FDA approved strategy for management of moderate to severe obstructive sleep apnea(OSA) patients with continuous positive airway pressure (CPAP) therapy intolerance or failure. Due to proximity of Cardiac Implantable Electronic Devices (CIED) and this stimulator, interaction between these devices is theoretically possible. OBJECTIVE: The purpose of this study was to assess interactions between implantable hypoglossal nerve upper airway stimulator device and cardiac implantable electronic devices...

BACKGROUND: Despite risks, complications and negative impact to quality of life, tracheostomy is widely used to bypass upper airway obstruction after major oral cancer surgery (MOCS). Decision to tracheostomy is frequently based on clinical scoring systems which mainly have not been validated by different cohorts. Delayed extubation in the Intensive Care Unit (ICU) may be a suitable alternative in selected cases. We hypothesize that delayed routine ICU extubation after MOCS instead of scoring system based tracheostomy is safe, feasible and leads to lower tracheostomy rates...

The upper airway (UA) in humans is commonly modeled as a Starling resistor. However, negative effort dependence (NED) observed in some patients with obstructive sleep apnea (OSA) contradicts predictions based on the Starling resistor model in which inspiratory flow is independent of inspiratory driving pressure when flow is limited. In a respiratory bench model consisting of a collapsible tube and an active lung model (ASL5000), inspiratory flow characteristics were investigated in relation to upstream, downstream and extra-luminal pressures (denoted as Pus, Pds and Pout, respectively) by varying inspiratory effort (muscle pressure) from -1 to -20 cmH2 O in the active lung...

More than 60% of people with tetraplegia have obstructive sleep apnoea (OSA). However, the specific causes are unknown. Genioglossus, the largest upper-airway dilator muscle, is important in maintaining upper-airway patency. Impaired genioglossus muscle function following spinal cord injury may contribute to OSA. This study aimed to determine if genioglossus reflex responses to negative upper-airway pressure are altered in people with OSA and tetraplegia compared to non-neurologically impaired able-bodied individuals with OSA...

Vocal cord dysfunction is an obstruction of the upper airway, primarily on inspiration, due to the paradoxical adduction of the vocal cords. Vocal cord dysfunction continues to be underdiagnosed as its own entity. The lack of diagnosis can be attributed to the overlap of symptoms between asthma and exercise-induced bronchospasm. It is possible for patients diagnosed with asthma and/or exercise-induced bronchospasm to have underlying vocal cord dysfunction, which needs to be considered when prescribing asthma medications...

BACKGROUND Previous studies have demonstrated that sustained hypoxia in people with obstructive sleep apnea (OSA) impairs upper airway muscle activity, but the underlying mechanism remains poorly understood. As autophagy acts as an important regulator under hypoxia stress, we performed an in vitro investigation of the effects of sustained hypoxia on autophagy of genioglossus muscle-derived stem cells (GG MDSC), an important component of the upper airway muscle. MATERIAL AND METHODS Genioglossus MDSCs were obtained from Sprague-Dawley (SD) rats and identified by using immunofluorescence staining for CD34, Sca-1, and desmin...

A 16-year-old boy with Chiari 1 malformation presented for an elective suboccipital craniectomy and C1 laminectomy. His intraoperative course was uneventful. At the conclusion of the procedure, he met extubation criteria and followed commands. After extubation, he developed progressive upper airway obstruction and became obtunded. He was reintubated via videolaryngoscopy, which showed edema not only to the tongue, but also to the posterior pharynx and blisters over the vocal folds and epiglottis. The patient was transferred to the pediatric intensive care unit intubated and sedated...

INTRODUCTION: Idiopathic subglottic stenosis (iSGS) is an unexplained progressive obstruction of the upper airway that occurs almost exclusively in adult, Caucasian women. The disease is characterised by mucosal inflammation and localised fibrosis resulting in life-threatening blockage of the upper airway. Because of high recurrence rates, patients with iSGS will frequently require multiple procedures following their initial diagnosis. Both the disease and its therapies profoundly affect patients' ability to breathe, communicate and swallow...

Background: Post-traumatic nasal septal collapse results in flat, broad, non-projecting nose due to mid-vault collapse. These patients may have airway obstruction due to poorly supported internal valve. Traditional techniques like 'cantilever graft technique' or conventional 'L-graft technique' produce a rigid lobule as the single unit framework extends to the tip. These grafts also lack in internal valve support. Materials and Methods: Twelve patients with post-traumatic nasal septal collapse were treated with three component cartilage framework technique in the past 3 years...

In patients with obstructive sleep apnea (OSA) the pharyngeal muscles become relaxed during sleep, which leads to a partial or complete closure of upper airway. Experimental studies suggest that withdrawal of noradrenergic and serotonergic drives importantly contribute to depression of hypoglossal motoneurons and, therefore, may contribute to OSA pathophysiology; however, specific cellular and synaptic mechanisms remain unknown. In this new study, we developed a biophysical network model to test the hypothesis that, in order to explain experimental observations, the neuronal network for monoaminergic control of excitability of hypoglossal motoneurons needs to include excitatory and inhibitory perihypoglossal interneurons that mediate noradrenergic and serotonergic drives to hypoglossal motoneurons...
