BACKGROUND: Parotid swelling is rarely caused by pneumoparotitis from retrograde insufflation of air into Stensen's duct. Previous reports have identified occupational exposures, self-induced habits, exercise, spirometry, and short-term positive pressure airway ventilation as causes of salivary duct insufflation. METHODS: We present 2 cases of pneumoparotitis in patients on long-term oronasal continuous positive airway pressure (CPAP) for obstructive sleep apnea...

Objectives: The aim of the study was to analyse differences in pharyngeal airway dimensions and head posture between obstructive sleep apnea patients with and without morphological deviations in the upper cervical spine and to analyse associations between pharyngeal airway dimensions and head posture in the total sample. Material and Methods: The sample comprised 53 obstructive sleep apnea (OSA) patients of which 32.1% had upper spine morphological deviations. Accordingly two groups were defined: 17 OSA patients with morphological deviations in the upper spine and 36 without upper spine deviations...

Study Design Case series with chart review. Setting Tertiary care pediatric hospital. Subjects and Methods We included 56 children undergoing DISE from October 2013 to September 2015 who underwent subsequent surgery to address OSA.

Patient interface preference is a key factor in positive airway pressure compliance. Local side effects are common. Proper mask fitting and patient education are important. Masks should seal well and fit comfortably. Nasal, nasal pillow, and oronasal masks can be effective interfaces. Most patients with obstructive sleep apnea prefer a nasal mask. Oronasal masks can be a useful alternative. Nasal pillows can reduce mask size and improve comfort. Oronasal masks may require a higher pressure. A significantly lower pressure may be effective with a nasal interface...

The prevalence and consequences of nasal obstruction in untreated obstructive sleep apnea patients are not known. The study objectives were to investigate the frequency of subjective and objective nasal obstruction in untreated sleep apnea patients and the associations with sleep and quality of life. Patients in the Icelandic Sleep Apnea Cohort were subjected to a type 3 sleep study, answered questionnaires and had their nasal dimensions measured by acoustic rhinometry. In total, 810 patients participated (including 153 females), aged 54...

The upper airway is a collapsible tube, and its collapsibility increases during sleep. Extrinsic factors such as atypical craniofacial features may increase the risks of airway collapse. We review early development of oral-facial structures and the anatomical variants that may be present at birth and can impact nasal breathing. After birth, there is a continuous interaction between orofacial functions and growth of anatomic features. We review the dysfunctions identified to date that may impact orofacial development leading to sleep-disordered-breathing through changes in the orofacial growth...

OBJECTIVE: The objective of this study was to investigate the effects of miniscrew-assisted rapid palatal expansion (MARPE) on changes in airflow in the upper airway (UA) of an adult patient with obstructive sleep apnea syndrome (OSAS) using computational fluid-structure interaction analysis. METHODS: Three-dimensional UA models fabricated from cone beam computed tomography images obtained before (T0) and after (T1) MARPE in an adult patient with OSAS were used for computational fluid dynamics with fluid-structure interaction analysis...

OBJECTIVE: To describe and assess the results of use of the new L-shaped posterior pharyngeal flap for repair of both palatal fistula and velopharyngeal incompetence. METHODS: This study included 10 patients who were diagnosed to have soft palate fistula and persistent velopharyngeal insufficiency (VPI). L-shaped superiorly based pharyngeal flap was harvested from oropharynx and inserted into the soft palate closing the fistula after fistula trimming. The palatal part of the flap (transverse limb) was spread 1 cm horizontally and 1 cm in the anteroposterior direction in soft palate at fistula site closing it without tension...

PURPOSE: We hypothesized that CIH may affect the upper airway immune system and aimed to verify whether CIH can induce airway inflammation in a murine obstructive sleep apnea (OSA) model. METHODS: C57BL6 male mice were exposed to intermittent hypoxia (CIH group; 5 ~ 21% FiO2, 120 sec cycles, 12 h/d, n = 6) or room air (Sham group, n = 6) for up to 4 weeks in identical chambers. Nasal and lung tissues and lavage fluid were collected and analyzed by multiplex assay...

OBJECTIVES: Investigate the presence of Eustachian Tube Dysfunction (ETD) in Obstructive sleep apnea (OSA) patients. Correlate the ET function and the severity of the sleep apnea syndrome. Correlate nasal resistance and nasal mucociliary clearance with the onset of ETD in these patients. MATERIALS AND METHODS: Forty patients affected by OSA were enrolled in our clinical prospective study. Thirty patients were also investigated as a control group. All of the analyzed subjects underwent ENT examination, anterior rhinomanometry and test for mucociliary transport time...

Obstructive sleep apnea (OSA) is common, and many cross-sectional and longitudinal studies have established OSA as an independent risk factor for the development of a variety of adverse metabolic disease states, including hypertension, insulin resistance, type 2 diabetes, nonalcoholic fatty liver disease, dyslipidemia, and atherosclerosis. Nasal continuous positive airway pressure (CPAP) has long been the mainstay of therapy for OSA, but definitive studies demonstrating the efficacy of CPAP in improving metabolic outcomes, or in reducing incident disease burden, are lacking; moreover, CPAP has variable rates of adherence...

BACKGROUND: Nasal continuous positive airway pressure (CPAP) in moderate-to-severe cases of obstructive sleep apnea cancause nasal discomfort and other undesirable problems. OBJECTIVE: The aim of our study was to test the effects of sodium hyaluronate on nasal problems that patients experienced in their daily lives, sleepiness, nasal resistance to airflow, nasal mucociliary clearance, changes in inflammatory markers, and compliance to CPAP in three groups of patients with obstructive sleep apnea syndrome on CPAP therapy...

Nasal obstruction is known to cause resistance to continuous positive airway pressure (CPAP) therapy in obstructive sleep apnea syndrome (OSAS). In this paper, short- and long-term nasal congestion in OSAS patients receiving CPAP treatment were evaluated with acoustic rhinometry (AR). A total of 36 patients with moderate-to-severe OSAS, diagnosed with polysomnography were included in the study. Ten healthy subjects without OSAS constituted the control group. Pre-treatment nasal patency were measured with AR in all participants...

Continuous positive airway pressure (CPAP) is the standard treatment for moderate-to-severe obstructive sleep apnoea (OSA). However, adherence to CPAP is limited and non-CPAP therapies are frequently explored. Oral appliance (OA) therapy is currently widely used for the treatment of snoring, mild, moderate and severe OSA. The most commonly used and studied OA consists of a maxillary and mandibular splint which hold the lower jaw forward during sleep. The efficacy of OA is inferior to CPAP; however, the effectiveness as measured by sleepiness, quality of life, endothelial function and blood pressure is similar likely due to higher acceptance and subjective adherence...

OBJECTIVE: Residual sleepiness after continuous positive airway pressure (CPAP) is a critical problem in some patients with obstructive sleep apnea syndrome (OSAS). However, nasal surgery is likely to reduce daytime sleepiness and feelings of unrefreshed sleep. The aim of this study is to clarify the effects of nasal surgery and CPAP on daytime sleepiness. METHODOLOGY: This is a retrospective and matched-case control study. The participants were consecutive 40 patients with OSAS who underwent nasal surgery (Surgery group) and 40 matched patients who were treated with CPAP (CPAP group)...
