PURPOSE: The aim of this work was to assess whether uvulopalatopharyngoplasty in patients with failure for positive airway pressure not only reduces the degree of obstructive sleep apnea but also to determine as well if it changes the collapse pattern of the soft palate and thereby fulfills the qualifications for implementing upper airway stimulation (UAS) as an adjunctive solution. METHOD: Fifteen patients with intolerance for positive airway pressure were included in this retrospective cohort study...

Diffuse idiopathic skeletal hyperostosis (DISH) is a rare but well known cause of dysphagia. In very few cases aspiration and dyspnea are described as a clinical manifestation. An 82-year-old man presented himself in our clinic with severe dyspnea, aspiration, and pneumonia. After performing a microlaryngoscopy an emergency tracheotomy became necessary. In laryngoscopy a severe bulging of the posterior oropharyngeal and hypopharyngeal wall was detected. The glottis area was not observable and immobilisation of the right vocal cord could be detected...

BACKGROUND: The integration of anatomical and nonanatomical parameters will improve our ability to predict the outcomes of OSA treatment. Currently, no standardized, quantitative classification of upper airway anatomical traits is available. The retropalatal (RP) airway is the most important area to consider when planning anatomical treatment. However, current evaluation methods feature qualitative conventional endoscopy. Here, we describe a quantitative magnetic resonance imaging (MRI) method used to classify RP airway patterns...

PURPOSE: The current management options of congenital pyriform aperture stenosis (CNPAS) are either conservative measures awaiting further growth of the bony nasal framework or surgical intervention that focuses on bone removal from the margin of the pyriform aperture (PA) without exposure of the nasolacrimal duct (NLD) followed by stenting. Recently, CT measurements of the nasal cavity in CNPAS have shed light that the site of maximal bony obstruction corresponds to the bony buttress encasing the NLD rather than the margin of the PA as initially thought...

Matt Lechner, Dominic Wilkins, Bhik Kotecha
Sleep disordered breathing (SDB) comprises a spectrum of disorders, ranging from simple snoring to severe obstructive sleep apnoea (OSA), with a significant burden to health care systems in high income countries. If left untreated, OSA has significant cumulative, long-term health consequences. In the 1990s drug induced sedation endoscopy (DISE) has been developed to become a primary tool in the diagnosis and management of OSA. It allows meticulous endoscopic evaluation of the airway and identifies areas of collapse, thereby informing both on the selection of surgical techniques, where efficacy depends entirely on success at relieving obstruction at a certain level and on the usefulness of conservative measures, such as mandibular advancement splints...

OBJECTIVES: A relatively neglected aspect of cleft lip nasal deformity is the effect of septal deviation and inferior turbinate hypertrophy (ITH) on the functional airway. In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH...

INTRODUCTION: deep sedation with propofol monitored by an endoscopist in different endoscopy units is a controversial subject and the source of conflicts of interest between the various scientific societies of Anesthesiology and Gastroenterology. Many studies have already demonstrated the efficacy, efficiency and low incidence of complications associated with sedation when under the control of a trained endoscopist vs an anesthesiologist. MATERIAL AND METHODS: the rate of severe cardiorespiratory complications during various endoscopic examinations (gastroscopy, colonoscopy, endoscopic retrograde cholangiopancreatography [ERCP] and endoscopic ultrasound [EUS]) where sedation was controlled by an endoscopist within our unit, from 2011 to 2016, was reviewed...

BACKGROUND: Amylase-trypsin inhibitors (ATIs) in wheat and related cereals are potent activators of myeloid innate immune cells via engagement of TLR4. Furthermore, ATIs have been shown to serve as adjuvants in experimental intestinal inflammatory diseases. OBJECTIVE: The aim of this study was to analyze whether ATIs are also modifiers of allergic inflammation. METHODS: Therefore, CD4+ T cells from grass or birch pollen sensitized donors were stimulated with autologous allergen-pulsed dendritic cells in the presence or absence of ATIs or the control storage protein zein from corn...

Suspension palatoplasty, a new surgical technique to treat obstructive sleep apnea (OSA), has been developed to correct the retropalatal obstruction in patients with small tonsils (grade I/II) and anterior-posterior palatal (A-P) obstruction. The objecteive of this preliminary study was to investigate the effectiveness and change in retropalatal airway dimensions after suspension palatoplasty. This retrospective case series study included 25 consecutive male adults with OSA. Unique technical features of suspension palatoplasty are exposure of pterygomandibular raphe and suspension of palatopharyngeus muscle to the raphe...

PURPOSE: Oral appliance therapy is an alternative treatment modality for obstructive sleep apnea (OSA). However, there have been no studies to determine whether changes in the obstructive pattern occur following long-term use of oral devices. Therefore, we examined whether the obstructive pattern changes in patients with OSA who undergo long-term oral appliance therapy using drug-induced sleep endoscopy (DISE). METHODS: We investigated 156 consecutive patients diagnosed with OSA...

OBJECTIVES: Confirmation of the endotracheal tube placement (CoETP) has the utmost importance in the management of an airway. Visualization of tracheal rings or carina with a fiber-optical bronchoscope (FOB) has considered to be a reliable method for the CoETP. However, FOB is expensive, time-consuming, and not always practical. Inexpensive endoscopic USB-cameras were shown to aid intubation successfully and reliably. On the other hand, there have been no studies investigating their use for the CoETP...

INTRODUCTION: The anti-inflammatory effects of long term low dose macrolide therapy have shown benefit in the management of diffuse panbronchiolitis. Dramatic responses to macrolide in the upper airway are seen but our understanding of the patient phenotype predisposing to macrolide response in chronic rhinosinusitis (CRS) is poor. METHODS: A case control study was performed in a tertiary level rhinology practice of consecutive chronic rhinosinusitis patients placed on a 3-month low dose macrolide therapy after failing at least 3 months of corticosteroid irrigation therapy post-endoscopic sinus surgery...
