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...

REVIEW
Geraldo Lorenzi-Filho, Fernanda R Almeida, Patrick J Strollo
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)...

This article analyzes the role played by the ear, nose and throat (ENT) specialist in the diagnosis and treatment of the Obstructive Sleep Apnea Syndrome (OSAS). DIAGNOSIS: The instrumental methods of investigation of otolaryngology expertise are fiberoptic rhinolaryngoscopy and sleep endoscopy. To better define and treat OSAS it is essential to define location, extension and degree of obstruction. The major limitation of rhinolaryngoscopy is that it is conducted while the patient is awake...

Patients with obstructive sleep apnea are frequently considered unsuitable candidates for awake craniotomy due to anticipated problems with oxygenation, ventilation, and a potentially difficult airway. At present, only a handful of such accounts exist in the literature. Our report describes the novel use of high-flow nasal oxygen therapy for a patient with moderate obstructive sleep apnea who underwent an awake craniotomy under deep sedation. The intraoperative application of high-flow nasal oxygen therapy achieved satisfactory oxygenation, maintained the partial carbon dioxide pressure within a reasonable range even during periods of deep sedation, permitted responsive patient monitoring during mapping, and provided excellent patient and surgeon satisfaction...

PURPOSE: Portable respiratory monitor (PRM) has been proposed for pre-diagnosis of obstructive sleep apnea syndrome (OSAS). However, discrepant physiological signal combinations were rarely studied for diagnostic assessment of OSAS. This study was designed to evaluate combination modes of key physiological signals collected by portable sensor modules for OSAS screening in comparison with polysomnography (PSG). METHODS: People with suspected OSAS were submitted to PRM at a sleep laboratory monitoring concurrently with PSG...

Numerous studies report that difficulty breathing through the nose is associated with reduced sleep quality, increased daytime dysfunction, and increased risk of snoring and obstructive sleep apnea (OSA). Additionally, chronic nasal obstruction often complicates and limits successful medical device therapy for OSA, particularly with continuous positive airway pressure (CPAP). When medical evaluation and management of the nose is inadequate, surgical therapy to lower nasal resistance has been shown to substantially improve sleep and breathing outcome measures...

STUDY OBJECTIVES: Continuous positive airway pressure (CPAP) is effective but challenging for children with obstructive sleep apnea (OSA). High-flow air via open nasal cannula (HFNC) as treatment in children remains controversial. We report the efficacy of HFNC in children with OSA and CPAP intolerance, a titration protocol, and a discussion of potential mechanisms. METHODS: Patients aged 1 to 18 years with OSA (defined by obstructive apnea-hypopnea index [OAHI] greater than 1 event/h) and CPAP intolerance were enrolled...

OBJECTIVE: The acoustic characteristics of voice are determined by the source of the sound and shape of the vocal tract. Various anatomical changes after uvulopalatal flap (UPF) operation can change nasalance and/or other voice characteristics. Our aim was to explore the possible effects of UPF creation on speech nasalance and the resonatory features of the final nasal consonants, and thus voice characteristics. METHODS: A total of 30 patients (26 males, 4 females) with obstructive sleep apnea who underwent UPF operation were recruited...

Short pauses or "transition-periods" at the end of expiration and prior to subsequent inspiration are commonly observed during sleep in humans. However, the role of transition periods in regulating ventilation during physiological challenges such as partial airway obstruction (PAO) has not been investigated. Twenty-nine obstructive sleep apnea patients and eight controls underwent overnight polysomnography with an epiglottic catheter. Sustained-PAO segments (increased epiglottic pressure over ≥5 breaths without increased peak inspiratory flow) and unobstructed reference segments were manually scored during apnea-free non-REM sleep...

OBJECTIVE: Patients with Myasthenia gravis (MG) are characterized by muscle weakness that may cause obstructive sleep apnea (OSA). The use of a continuous positive airway pressure (CPAP) device is often needed in order to maintain free breathing during the night and sometimes even during the day. CLINICAL PRESENTATION: A 29-year-old MG patient is presented who used a CPAP continuously since the age of 12. Tight fitting of a nasal mask applied enough force to cause severe maxillary deformity...

A narrow maxilla with high arched palate characterizes a phenotype of obstructive sleep apnea (OSA) patients that is associated with increased nasal resistance and posterior tongue displacement. Current maxillary expansion techniques for adults are designed to correct dentofacial deformity. We describe distraction osteogenesis maxillary expansion (DOME) tailored to adult patients with OSA with narrow nasal floor and high arched palate without soft tissue redundancy. DOME is performed with placement of maxillary expanders secured by mini-implants along the midpalatal suture...
