“…The authors, while studying the same group of patients, have showed previously that there is a statistically significant effect of the diameter of upper airways at the level of the soft palate on the AHI value (p = 0.01), and this is a negative correlation, indicating that an increase in the value of AHI with the decreasing diameter of the pharynx on this level. At the same time, no significant impact of the value of the lower diameter of the upper airway at the base of the tongue on the AHI value was confirmed [13]. Many authors had previously confirmed the reduced values of the upper airways diameter in individuals with OSA [1,6,7,8,10,14].…”

“…Researchers have previously reported smaller airway diameters in patients with OSA. 9 10 Szymanska et al 11 reported smaller upper airway diameters than the standards set by Mc-Namara on lateral cephalograms in patients with OSA. Martin et al 12 found that as the upper airway diameter decreased, the number of apnea or hypopnea episodes increased.…”

“…The UAD was measured from the point on the anterior half of the soft palate to the closest point on the outer pharyngeal wall. 11 The MP-H was measured by drawing a tangent to the mandibular plane, then measuring the distance to the hyoid bone from that tangent ( Fig. 1 ).…”

PurposeObstructive sleep apnea (OSA) is a common medical disorder with serious complications if untreated. Dentists play a vital role in the early diagnosis of this condition, thereby improving patients' prognoses. The purpose of this study was to identify patients with a high risk of OSA using simple cephalometric measurements in patients receiving routine dental care.Materials and MethodsThe present study was conducted on 206 patients divided into a high-risk group and a control group after answering the Berlin questionnaire. Cephalometric analysis of a digital cephalogram was performed to measure the upper airway diameter (UAD) and mandibular-to-hyoid bone distance (MP-H) by 2 observers at 2 different times.ResultsAmong 206 patients, 93 (45%) were included in the high-risk group and 113 (55%) were in the control group. No significant difference was present between the groups with regard to gender, and the patients ranged in age from 18 to 65 years. The UAD measurements in the high-risk group were significantly lower than in the control group, and the MP-H measurements were significantly higher in the high-risk group than in the control group. The UAD was lower in middle-aged patients in both groups.ConclusionOur study found that the UAD was lower in individuals with a high risk of OSA. Also, we found that middle-aged individuals of both genders were more likely to develop OSA. Dentists play a vital role in diagnosing patients at a high risk for OSA via thorough clinical examinations, risk factor analyses, and simple cephalometric analyses.

“…Despite this, the reported associations are wide-ranging from little to statistical significance. [4][5][6][7][8][9][10] Common areas of focus include the assessment of the posterior airway space, tongue size, adenoid mass, minimum cross-sectional area and soft palate length from cephalometric and cone beam analysis. However, once these parameters were identified, there is less guidance regarding the best course of action.…”

Introduction: The aim was to assess the relationship between airway morphology and surgical intervention in a cohort of patients presenting with increased body mass index (BMI) and a confirmed diagnosis of obstructive sleep apnoea (OSA). A secondary aim was to revisit the relationship between morphology and OSA severity. Methods: A retrospective analysis was conducted of pre-operative maxillofacial 3D-CT scans of thirty-two patients with a confirmed diagnosis of OSA who received treatment from an ear nose and throat specialist (ENT). Lateral cephalograms were imported into Quick Ceph Studio (Quick Ceph Systems Inc, San Diego, CA, USA) after which linear and angular measurements of selected hard and soft tissues were obtained. 3D-CT images were loaded into the software program 3dMDVultus (3dMD) which permitted 3D visualisation of the airway. Measurements were repeated 3 times on the images of six patients after an interval of two weeks to establish the intraclass correlation coefficient (ICC) for intra-examiner accuracy and reliability. Logistic regression was applied to determine the relationships between morphology, OSA and surgical treatments. Results: A positive correlation was found between age and the apnoea-hypopnea index (AHI). Morphological measurements of the airway did not exhibit a positive relationship with OSA severity. Posterior airway space at the level of the uvula and tongue, the length of the soft palate and position of the hyoid bone were significantly associated with BMI. No variables were found to be correlated with uvulopalatopharyngoplasty (UPPP) surgery. Notwithstanding, airway length and posterior airway space at the level of the uvula tip were significantly associated with tongue channelling. Conclusions: Radiographic airway assessment is an invaluable and opportunistic tool for screening OSA but requires judicial use in its prescription and interpretation. There is little correlation between OSA severity and airway morphology and between surgical intervention and morphology. Additional factors need to be considered before a treatment modality is considered and is best managed in a multidisciplinary setting.
