AbstractObjectivesObstructive sleep apnoea is a common chronic sleep disorder characterised by collapse of the upper airway during sleep. The nasal airway forms a significant part of the upper airway and any obstruction is thought to have an impact on obstructive sleep apnoea. A systematic review was performed to determine the role of rhinological surgical interventions in the management of obstructive sleep apnoea.MethodsA systematic review of current literature was undertaken; studies were included if they involved comparison of a non-surgical and/or non-rhinological surgical intervention with a rhinological surgical intervention for treatment of obstructive sleep apnoea.ResultsSixteen studies met the selection criteria. The pooled data suggest that there are reductions in the apnoea/hypopnea index and respiratory disturbance index following nasal surgery. However, the current body of studies is too heterogeneous for statistically significant meta-analysis to be conducted.ConclusionNasal surgery may have limited benefit for a subset of patients based on current evidence.

OBJECTIVES: Sleep apnoea has been consistently reported to occur in acromegaly. Both obstructive apnoeas, in which apnoeas are due to intermittent obstruction of the upper airways, as well as central apnoeas are known to occur. Because the relationship between disease activity and severity of sleep apnoea is currently unclear, we have performed a prospective study to address this issue. DESIGN AND METHODS: In 14 newly diagnosed patients with active acromegaly (eight females and six males; mean age 57+/-4 years; IGF-I 583+/-48 microg/l; GH 13.5+/-7.0 microg/l (means+/-s.e.m.)), tongue volume and signal intensity of the tongue were examined by magnetic resonance imaging and sleep apnoea was characterised by polysomnography before and after 6 months of treatment with octreotide acetate (Sandostatin LAR 10-30 mg every 4 weeks i.m.). RESULTS: The initial tongue volume was significantly higher in patients with acromegaly (151+/-9 ml; females 133+/-10 ml; males 172+/-10 ml) in comparison with the body mass index (BMI)- and age-matched healthy control group (97+/-5 ml, P<0.001; females 75+/-1 ml, P<0.001; males 120+/-3 ml, P<0.003). After treatment with octreotide, IGF-I was normalised within the age-adjusted normal range in 50% of the patients. In these patients, tongue volume significantly decreased (120+/-14 ml, P<0.05) in comparison with the persistent uncontrolled group of acromegalics (137+/-10 ml, P=not significant). Overall, tongue volume (128+/-8 ml, P<0.05) and the signal intensity ratio of the tongue decreased significantly after treatment with octreotide acetate (120+/-3 vs 105+/-3, P=0.003). The BMI-adjusted tongue volume correlated with IGF-I levels (r=0.60, P<0.002) and the disease duration (r=0.71, P=0.006). At baseline, 50% had obstructive sleep apnoea with a mean respiratory disturbance index (RDI) of >20/h (range 5.1-91.5) and no patient had central sleep apnoea. After 6 months of octreotide treatment, there was a 28+/-10% decrease in RDI. However, RDI did not correlate with IGF-I or GH levels, but correlated positively with BMI (r=0.58, P=0.001) and age (r=0.46, P=0.02). CONCLUSIONS: Obstructive sleep apnoea but not central sleep apnoea frequently occurs in patients with active acromegaly. Successful treatment with octreotide can decrease tongue volume, which may have benefits for coexisting sleep-disordered breathing.

IntroductionObstructive sleep apnoea (OSA) is caused by complete or partial obstruction of the upper airway resulting in repeated episodes of interrupted or shallow breaths. OSA is associated with significant morbidity and mortality. The prevalence is estimated to range from 3% to 7% in the general population but may be much higher. Several studies show that weight loss or bariatric surgery may have a role in treating OSA. The aim of this systematic review is to assess the safety and efficacy of randomised controlled trials (RCTs) of weight loss surgery for adults with OSA and comorbid obesity.Methods and analysisA search of the Cochrane Central Register of Controlled Trials, PubMed, EMBASE and two major Chinese biomedical databases will be performed to identify related trials published as of October 2018. This study will include RCTs, comparing different types of weight loss surgery for OSA with obesity or weight loss surgery for OSA with obesity with other upper airway surgeries. The primary outcomes that will be measured are apnoea–hypopnoea index, excess weight loss and in-hospital mortality. The secondary outcomes will include duration of hospital stay, neck circumference, reoperation, waist circumference, body mass index, Epworth Sleepiness Scale score, overt complications (eg, gastric fistula, bleeding, delayed gastric emptying, wound infection), quality of life, quality of sleep and/or functionality. The systematic review will be conducted according to the recommendations as outlined by the Cochrane collaboration.Ethics and disseminationThe systematic review and meta-analysis will include published data available online and thus ethics approval will not be required. The findings will be disseminated and published in a peer-reviewed journal. Review updates will be conducted if there is new evidence that may cause any change in review conclusions. Any changes to the study protocol will be updated in the PROSPERO trial registry accordingly.PROSPERO registration numberCRD42017081743.

Summary Background Obstructive sleep apnoea (OSA) is a common sleep-related breathing disorder, attributed to the collapse of the pharyngeal walls and the subsequent complete or partial upper airway obstruction. Among different treatment options for OSA, Continuous Positive Airway Pressure, and oral appliances (OAs) have been used, with various outcomes and side effects. Objective The aim of this study was to summarize current knowledge in an evidence-based manner regarding the upper airway volume increase of OSA patients while treated with OAs. Search methods Electronic search was conducted in Pubmed, Cochrane Library, and Scopus, up to May 2020. Selection criteria Studies were selected after the application of predetermined eligibility criteria. Data collection and analysis Mean airway volume differences and the corresponding 95% confidence intervals were calculated, using the random effects model. Sensitivity, exploratory, and meta-regression analyses were also implemented. Results Eleven studies filled the inclusion criteria and were included in the systematic review, while 10 of them were suitable for meta-analysis. In total, 291 patients were included, with mean upper airway volume increase of 1.95 cm3 (95% CI, 1.37–2.53; P &lt; 0.001) with Mandibular Advancement Devices in place. In all studies, post-treatment Apnea Hypopnea Index (AHI) was either &lt;10 events/hour or was reduced by more than 50% from baseline levels. A greater increase of the velopharynx volume was observed, regarding airway compartments. Conclusions Treatment with OAs in OSA may lead to a significant increase of the upper airway volume with a subsequent decrease of AHI. The velopharynx seems to be affected the most from OA therapy.
