Airway Morphology

AbstractObjectiveTo evaluate the upper airway morphology changes associated with ageing in adult Chinese patients with obstructive sleep apnoea.MethodsA total of 124 male patients diagnosed with obstructive sleep apnoea by overnight polysomnography, who underwent upper airway computed tomography, were enrolled. The linear dimensions, cross-sectional area and volume of the upper airway region and the surrounding bony frame were measured. The association between ageing and upper airway morphology was analysed.ResultsSoft palate length, minimum cross-sectional area of the retroglossal region, lateral dimensions at the minimum cross-sectional area of the retropalatal and retroglossal regions, nasopharyngeal volume, and average cross-sectional area of the nasopharyngeal region were found to significantly increase with ageing in all patients, while the upper airway shape flattened with ageing. The volume of the retropalatal region increased with ageing among the patients with a body mass index of less than 24 kg/m2. The volume of parapharyngeal fat pad increased with ageing among patients with a body mass index greater than 28 kg/m2.ConclusionA number of dimensional, cross-sectional and volumetric parameters of the pharynx increased with age, indicating that non-anatomical factors may play a more important role in the pathogenesis of obstructive sleep apnoea in aged patients.

ObjectivesPaediatric obstructive sleep apnoea–hypopnoea syndrome (OSAHS), which usually cooccurs with various diseases, significantly impacts health and social resources. Domestic paediatric OSAHS studies have not included comorbidity patterns or distribution characteristics. Thus, we investigated the comorbid characteristics of paediatric OSAHS in Shanghai, China.DesignLarge hospital-based cross-sectional study.SettingPaediatric ward medical data from the Pudong New Area, Shanghai, China from 2013 to 2016.Participants4045 Chinese children aged 0–18 years.Primary and secondary outcome measuresPaediatric OSAHS was diagnosed using the Paediatric Sleep Questionnaire with a cut-off score of 8 points. The outcomes were comorbidity patterns and their characteristics. χ2 tests were performed to compare differences among the top comorbidity patterns.ResultsMajor comorbidities were otolaryngological morbidities. Among one-comorbidity patterns, OSAHS+chronic rhinitis (37.53%) and OSAHS+allergic rhinitis (28.13%) were most common. Among two-comorbidity patterns, OSAHS+chronic rhinitis +chronic exudative otitis media (10.88%), OSAHS+allergic rhinitis +chronic exudative otitis media (7.94%), OSAHS+allergic rhinitis +chronic tonsillitis (4.43%) and OSAHS+chronic rhinitis +chronic tonsillitis (4.23%) were most common. Males predominated in all comorbidity groups. Age differences for the top five patterns in both the one-comorbidity (p=0.035) and two comorbidities (p<0.001) groups were statistically significant. In the one-comorbidity group, patients were more likely to have one operation (p<0.001), and in the two comorbidities group, patterns of ‘OSAHS+chronic rhinitis +chronic exudative otitis media’ and ‘OSAHS+allergic rhinitis +chronic exudative otitis media’ were more common in the ≥2 operations group (p<0.001). Notably, the top five patterns of the 2-comorbidities group were significantly associated with the length of stay (LOS) (p<0.001), while those in the one-comorbidity group were not.ConclusionOSAHS+rhinitis (chronic rhinitis or allergic rhinitis) was the most common diagnosis. Age, number of operations, and LOS are significantly associated with the patterns. This emphasises the importance of better understanding complex otolaryngological comorbidity diagnoses and treatments in paediatric OSAHS to reverse clinical outcomes and save health resources.

Obstructive Sleep

ObjectivesObstructive sleep apnoea (OSA)/hypopnoea syndrome is associated with serious and major multiorgan morbidities, particularly in its most severe forms. However, no severe OSA screening instruments are available for high altitude residents that enable adequate identification and clinical prioritisation of such patients. We aimed at developing a severe OSA prediction tool based on the clinical characteristics and anthropometric measurements of a clinical referral cohort living at 2640 m.a.s.l.DesignCohort-nested cross-sectional study.SettingSleep laboratory for standard polysomnography (PSG) in Colombia.ParticipantsA predictive model was generated from 8718 participants referred to the PSG laboratory. Results were subsequently validated in a second cohort of 1898 participants.Primary outcomeTo identify clinical and anthropometric variables associated with severe OSA (>30 events/hour) and to include them in a binary logistic regression model.ResultsThe significant variables that were retained with the presence of severe OSA included Body mass index (BMI), Age, Sex, Arterial hypertension and Neck circumference (BASAN). The area under the receiver operating characteristic curvefor the BASAN index was 0.69 (95% CI: 0.68 to 0.70) in the derivation cohort and 0.67 (95% CI: 0.65 to 0.69) in the validation cohort, whereby a BASAN index ≥2 had a sensitivity of 95% and a specificity of 17% to detect severe OSA.ConclusionAn objectively based approach to screen for the presence of severe OSA, the BASAN index, exhibits favourable sensitivity characteristics that should enable its operational use as a screening tool in a Hispanic population with a clinical suspicion of OSA and living at high altitude.
