“…Our results differed from what was shown in a recent work that evaluated 170 patients in the south of Egypt in whom 59% were diagnosed with OSA agreeing to a recent work that evaluated 120 patients [28,29]. Also, in a sample of 80 patients, OSA was diagnosed in 65% of them almost equal to another work that examined 145 patients referred for polysomnography [30,31].…”

Background Obstructive sleep apnea (OSA) is a common condition in the general population that is highly correlated to obesity, and it is associated with major cardiovascular morbidity and mortality. In Egypt, obesity rates are known to be high; however, OSA remains largely under-diagnosed, and data on its current magnitude is very scarce. Thus, the aims of the study were to identify the percentage of OSA in a large sample of patients referred for polysomnography and to determine the effect of different demographic data on the severity of the disease. Results This retrospective study included 1012 patients. Medical data were reviewed by sleep specialists. The correlation between age, body mass index (BMI), and neck circumference (NC) with apnea hypoapnea index (AHI) was explored. Also, gender differences were analyzed. A total of 838 patients (81% males, 19% females) were diagnosed with OSA. Patients with mild, moderate, and severe OSA were 204 (24%), 146 (17%), and 488 (58%), respectively. Females were older than males (58.87 ± 10.25 versus 54.39 ± 22.96, p = 0.001) and BMI was not significantly different between both sexes (34.18 ± 13.53 versus 36.73 ± 23.25, p = 0.07), but NC was higher in men (43.56 ± 5.3 versus 39.34 ± 4.41, p = 0.001). AHI was significantly increased in men compared to women (47.97 ± 31.22 versus 37.95 ± 31.72, p = 0.001) and severe OSA was commonly diagnosed in men than women (p = 0.001). A positive significant correlation was found between BMI, NC with AHI, arousal index, average SpO2, and desaturation index. Conclusion OSA is highly prevalent among our patients. Additionally, BMI and NC independently affected the severity of their disease.

“…Retropalatal pharynx transverse diameter was significantly lower in the mild OSA group than in the normal group in the present study. This finding was in agreement with Ali and Muhammad [32] who found a highly significant decrease in RPD in OSA patients compared to the controls. In addition, they observed significant progressive shortening and narrowing for RPD with progression of OSA severity and AHI.…”

Instroduction: Obstructive sleep apnea is a common disorder, characterized by recurrent narrowing and closure of the upper airway accompanied by intermittent oxyhemoglobin desaturation and sympathetic activation. Ultrasound imaging of the airways has advantages of being safe, quick, repeatable, portable and widely available. Airway ultrasound can visualize and assess the mouth and tongue, oropharynx, hypopharynx, epiglottis, larynx, vocal cords, cricothyroid membrane, cricoid cartilage, trachea, and cervical esophagus. Material and methods: This study assessed the role of ultrasonography in detecting the level and degree of obstruction of airway passages in patients with obstructive sleep apnea (OSA) and its relation to OSA severity. It included thirty-three patients diagnosed as OSA, and ten healthy subjects as a control group. All participants were ≥ 18 years and were subjected to full medical history, Epworth sleepiness score (ESS), thorough clinical examination, complete overnight polysomnography and neck ultrasonography. Results: Ultrasonography findings showed a statistically significant increase in lateral parapharyngeal wall thickness (LPWT) (P < 0.001) and a significant increase in distance between lingual arteries (DLA) (P < 0.01) among OSA patients. Moreover, there was a significant statistical decrease in the retropalatal pharynx transverse diameter (RPD) (P < 0.05) in the OSA group compared to those without OSA. LPWT and DLA are parameters that can be used to predict the severity of OSA. Combination of LPWT and RPD can achieve a 100% sensitivity and specificity. Conclusions: Ultrasound is more objective and convenient than the questionnaire because it doesn’t require overnight time consumption. It is also more relevant than pulse oximetry for examining pharyngeal airspace. Also, this study demonstrated that submental ultrasonography is sufficiently sensitive for differentiating OSA severity.
