Decreased maxillary sinus volume is a potential predictor of obstructive sleep apnea.

CONCLUSIONS: A decreased ratio of maxillary sinus volume to whole nasal airway volume is associated with adult OSA. However, OSA severity is not associated with either maxillary sinus volume or whole nasal airway volume. PMID: 32091265 [PubMed - as supplied by publisher]

ConclusionsAnterior osteotomy just to the midline of inferior border and horizontal osteotomy to the mandibular foramen are associated with split patterns that result in optimal rigid fixation and passive bony overlap for OSA patients undergoing MMA.Clinical relevanceOptimal surgical technique has the most significant influence in allowing rapid return to function after MMA in patients with OSA.

AbstractObjectiveTo explore the application of three-dimensional (3D) reconstruction technology for midline glossectomy in patients with obstructive sleep apnea (OSA).MethodsFifteen patients with OSA were included in this study. Each of them received computed tomography angiography (CTA) examination of lingual arteries in the resting tongue position and fully extended tongue position respectively. The two-dimensional CTA images were converted to 3D models using 3D reconstruction technology. We simulated the midline glossectomy in different tongue positions with a safe margin of 3  mm. The differences in the distances ...

Conclusions: OSA frequency is 62.8% in patients with bronchiectasis.50% of patients without main complaints have OSA. PSG should be performed in all patients with bronchiectasis, even if they do not have main complaints about OSA.

Conclusion: Patients with greater pulmonary artery obstruction had more sever sleep apnea. PAOI>40%, RV/ LV>1 were predictors of sleep apnea among patients with acute PE.

AbstractObstructive Sleep Apnea (OSA) is strongly associated with adverse cardiovascular events. In these patients, increased oxidative stress has been associated with accelerated coronary atherosclerosis. However, it is unclear if OSA is associated with significant coronary artery plaque burden. Our aim is to determine whether OSA and/or markers of hypoxemia are associated with coronary plaque burden (CPB). Patients who had coronary computed tomography angiography (CCTA) and a polysomnogram within 1  year of each other between 2011 and 2016 were analyzed. Apnea–Hypopnea Index (AHI) and hypoxemic burden (ODI3%, ...

A 57-year-old male with known history of obstructive sleep apnea was admitted for shortness of breath. On exam, patient was tachycardic with increased jugular venous pressure. Electrocardiogram showed sinus tachycardia with right ventricular strain and ST-segment depressions in the lateral leads. A computed tomography pulmonary angiography (CTPA) demonstrated no evidence of pulmonary embolism. Incidentally, a double aortic arch (DAA) was noted on CTPA (Fig. 1, Fig. 2). On laboratory exam, the patient had elevated troponin I at 0.276 ng/mL.

Authors: Bamford P, Lau GT Abstract A 77-year-old woman with obstructive sleep apnea presented with a 3-week history of leg swelling and dyspnea on exertion. She had a dry cough and lost 10 kg over the past 2 years. Examination revealed elevated jugular venous pressure, reduced air entry in the left lower-lung field, and pedal edema. Imaging with chest computed tomography revealed a giant pedunculated left atrial myxoma to be the cause of her severe pulmonary hypertension, which was reversible with treatment.

This study aimed to investigate the relationship between the severity of OSAS and PH morphology and other anatomical variations of the upper airway.MethodsThe data of the patients who underwent polysomnography and diagnosed with OSAS were retrospectively reviewed, and those who underwent paranasal sinus computed tomography were determined. The patients were divided into three groups according to the apnea –hypopnea index (AHI) scores obtained from the polysomnography (mild, moderate, and severe). The relationship between PH thickness, length and interpterygoid distance, and the severity of AHI was investigated.Result...
