The present statement was produced by a European Respiratory Society Task Force to summarise the evidence and current practice on the diagnosis and management of obstructive sleep disordered breathing (SDB) in children aged 1-23 months. A systematic literature search was completed and 159 articles were summarised to answer clinically relevant questions. SDB is suspected when symptoms or abnormalities related to upper airway obstruction are identified. Morbidity (pulmonary hypertension, growth delay, behavioural problems) and coexisting conditions (feeding difficulties, recurrent otitis media) may be present...

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: Recurrent respiratory papillomatosis is characterized by wart-like lesions of the upper airway and is most frequently caused by human papillomavirus (HPV). The disease has significant impact on quality of life due to potential airway obstruction, dysphonia and the need for serial surgeries. The main objective of this study was to describe patient characteristics and long-term follow-up data in a Danish cohort with the disease. METHODS: The study was a longitudinal retrospective cohort-study using data from electronic medical records and a pathology database...

Objective: To determine the level of agreement among experienced operators of candidacy for upper airway stimulation (UAS) based on evaluation of drug-induced sleep endoscopy (DISE). Methods: The trial was designed as a single-blinded cross-sectional study. Four otolaryngologists with extensive DISE experience were given 63 video clips from the STAR trial video library. These videos were graded using the VOTE classification. Percentage agreement and Cohen's κ (for inter-rater reliability) were calculated between pairs of reviewers, assessing palatal complete concentric collapse (CCC) and determining UAS eligibility...

A cat that underwent bilateral ventral bulla osteotomy (VBO) for treatment of otitis media and otitis interna secondary to bilateral inflammatory polyps, developed upper airway obstruction (UAO) soon after tracheal extubation. The cat was re-intubated but the UAO did not resolve at the next extubation. Eventually, tracheostomy was performed. Upper airway obstruction is a potential postoperative complication of bilateral VBO in cats.

It has been suggested that the high prevalence of obstructive sleep apnea (OSA) in resistant hypertension (RHT) may be related to the high prevalence of primary aldosteronism (PA) in patients with RHT. It has been also hypothesized that the relationship between aldosterone and OSA might be bidirectional. In patients with RHT, it has been shown that aldosterone levels correlate with severity of OSA and that blockade of aldosterone reduces the severity of OSA. It has been postulated that aldosterone worsens OSA by promoting accumulation of fluid, which shifted in the supine position to the neck, contributes to increased upper airway resistance...

Stridor is a result of turbulent air-flow through the trachea from upper airway obstruction, and although in children it is often due to croup, it can also be caused by noninfectious and/or congenital conditions as well as life-threatening etiologies. The history and physical examination guide initial management, which includes reduction of airway inflammation, treatment of bacterial infection, and, less often, imaging, emergent airway stabilization, or surgical management. This issue discusses the most common as well as the life-threatening etiologies of acute and chronic stridor and its management in the emergency department...

The objective of this report is to present clinical and scientific evidence to support the role of head position in the management of obstructive sleep apnea (OSA) with positive airway pressure. OSA, characterized by repetitive obstruction of the upper is a common medical condition associated with daytime somnolence, morning headaches, mood disturbances, and a variety of cardiopulmonary complications. The role of head position during obstructive respiratory events has been largely overlooked. We present a case where OSA severity decreased significantly with the head rotated in the right lateral position compared to head position in the neutral and left position...

PURPOSE: Obesity is associated with both obstructive sleep apnea (OSA) and obesity hypoventilation. Differences in adipose tissue distribution are thought to underlie the development of both OSA and hypoventilation. We explored the relationships between the distribution of upper airway, neck, chest, abdominal and muscle fat in very obese individuals. METHODS: We conducted a cross-sectional cohort study of individuals presenting to a tertiary sleep clinic or for assessment for bariatric surgery...

Congenital arhinia is one of the rare craniofacial malformation that may cause severe respiratory distress at birth due to upper airway obstruction. Our patient, whose abnormalities were only detected after delivery in our centre, is the first reported case of congenital arhinia in Malaysia. Contrary to popular belief that neonates are obligate nasal breather, our patient adapted well to breathing through mouth before an elective tracheostomy was performed on day four of life.

BACKGROUND: Previously, we and other investigators have described reversible loss of lung elastic recoil in acute and persistent loss in moderate-to-severe, chronic, treated asthmatics who never smoked, and its adverse effect on maximal expiratory airflow. In 4 consecutive autopsies, the pathophysiologic mechanism(s)has been unsuspected mild, diffuse, middle and upper lobe centrilobular emphysema. METHODS: We performed prospective studies (5-22 years) in 25(12F) chronic asthmatics age 55±15 yr who never smoked, with persistent moderate-to-severe expiratory obstruction...

REVIEW
Thomas Penzel, AbdelKebir Sabil
Tracheal sounds have been the subject of many research studies. In this review, we describe the state of the art, original work relevant to upper airways obstruction during sleep, and ongoing research concerning the methods used when analysing tracheal sounds. Tracheal sound sensors are a simple and noninvasive means of measurement and are more reliable than other breathing sensors. Developments in acoustic processing techniques and enhancements in tracheal sound signals over the past decade have led to improvements in the accuracy and clinical relevance of diagnoses based on this technology...

BACKGROUND: Neurogenic tumors of the tracheobronchial tree are extremely rare and include neurofibroma and schwannoma. We report a case of primary recurrent tracheal schwannoma causing obstructive airway symptoms. CASE PRESENTATION: A 60-year-old man presented with obstructive airway symptoms due to recurrent tracheal schwannoma. Due the recurrence, size of the tumor and low surgical risk, the patient was treated with tracheal resection. CONCLUSION: Primary endotracheal neurogenic tumors are extremely rare, but one should consider them in the differential diagnosis of persistent upper airway symptoms...

Study Objectives: Following extubation in the intensive care unit (ICU), upper airway (UA) edema and respiratory depressants may promote UA dysfunction. We tested the hypothesis that opioids increase the risk of sleep apnea early after extubation. Methods: 56 ICU patients underwent polysomnography the night after extubation. Airflow limitation during wakefulness was identified using bedside spirometry. Correlation and ordinal regression analyses were used to quantify effects of pre-extubation opioid dose on post-extubation Apnea-Hypopnea-Index (AHI) and severity of sleep apnea and whether or not inspiratory airway obstruction (ratio of maximum expiratory and inspiratory flow at 50% of vital capacity (MEF50/MIF50)≥1) during wakefulness predicts airway obstruction during sleep...

BACKGROUND: Obstructive sleep apnea (OSA) affects two third of morbidly obese individuals undergoing bariatric surgery. Perioperative usage of continuous positive airway pressure (CPAP) is advised for moderately and severe OSA to avoid respiratory failure and cardiac events. CPAP increases the air pressure in the upper airway, but also may elevate the air pressure in the esophagus and stomach. Concern exists that this predisposes to mechanical stress resulting in suture or staple line disruption (further referred to as suture line disruption)...

OBJECTIVES: Subglottic stenosis (SGS) is one of the most common airway disorders in pediatric patients. Currently, treatment decisions rely primarily on the Cotton-Myer scale, which classifies SGS severity based on percentage reduction in airspace cross-sectional area (CSA). However, the precise relationship between upper airway resistance and subglottic CSA is unknown. We hypothesize that airway resistance can be described by the Bernoulli Obstruction Theory, which predicts that airway resistance is inversely proportional to airspace CSA ( R∝A-1) in cases of severe constriction...
