“…Moreover, MP-H exhibited significant correlations with airspace width at the oropharynx, tongue base, and epiglottis. Our research found obstruction sites in the oropharynx, tongue base, and epiglottis, which correlated with airspace width, while a recent study reported that patients with moderate-to-severe OSA (AHI ≥ 15) had reduced airspace in the velum, oropharynx, and tongue base region [ 29 ]. Our study presents a novel finding as it uses airspace width as the measurement variable to correlate with cephalometric parameters.…”

“…Our study presents a novel finding as it uses airspace width as the measurement variable to correlate with cephalometric parameters. However, cephalometric data [ 4 , 19 , 20 , 21 , 22 , 23 ] and ultrasonic parameters [ 29 ] have been reported in prior research as being correlated with the apnea–hypopnea index (AHI). This study did not conduct polysomnography; therefore, the relationship’s direction (positive or negative) ( Figure 6 ) does not correspond with the severity of OSA.…”

“…These indicate that the airspace–tissue width ratio may not relate to craniofacial structure in patients with a high risk of OSA. However, a recent study found that patients with moderate-to-severe OSA (AHI ≥ 15) showed a strong correlation with the airspace–tissue width ratio in the velum region [ 29 ]. This may be attributed to discrepancies in the variables used in the correlation analysis.…”

“…On the contrary, previous studies have discovered that patients with moderate-to-severe OSA had thicker superficial and deep tissue in the oropharynx region. This may be attributed to lower position of the hyoid bone [ 29 ]. This might be due to ethnic heterogeneity in craniofacial structure.…”

“…The predictive model, utilizing multivariate analysis, produced an AUROC of 0.839 in estimating the probability of moderate-to-severe OSA (AHI ≥ 15/h). This model is based on significant features such as the narrowing of airways at the velum, oropharynx, and tongue base, as well as a substantially broader tongue and thicker deep tissue [ 29 ].…”

Background/Objectives: Polysomnography and cephalometry have been used for studying obstructive sleep apnea (OSA) etiology. The association between craniofacial skeleton and OSA severity remains controversial. To study OSA’s etiology, cephalometry, fiberoptic pharyngoscopy, polysomnography, and sleep endoscopy have been used; however, airway obstructions cannot be located. Recent research suggested ultrasonography for OSA screening and upper airway obstruction localization. Thus, this study aims to investigate the relationship between specific craniofacial cephalometric and ultrasonic airway parameters in adults at high risk of OSA. Methods: To assess craniofacial structure, lateral cephalograms were taken from thirty-three adults over 18 with a STOP-Bang questionnaire score of three or higher and a waist-to-height ratio (WHtR) of 0.5 or higher. Airway parameters were assessed through submental ultrasound. Results: NSBA correlated with tongue base airspace width, while MP-H correlated with oropharynx, tongue base, and epiglottis airspace width. SNA, SNB, and NSBA correlated with tongue width at the oropharynx. At tongue base, ANB and MP-H correlated with tongue width. SNB and NSBA were associated with deep tissue thickness at the oropharynx, while MP-H correlated with superficial tissue thickness at velum and oropharynx. Conclusions: Cephalometric parameters (SNA, SNB, ANB, NSBA, and MP-H) were correlated with ultrasonic parameters in the velum, oropharynx, tongue base, and epiglottis.
