Analysed cephalometric data totally supported the concept of soft-tissue abnormalities in subjects with OSA, skeletal-only halfway; MP-H and SPAS being the most reliable parameters. Increased MP-H may serve as a predictor when differentiating normal subjects and patients with OSA. Reduced SPAS width could be a prognostic parameter for suspecting OSA. These two values should be kept in mind by dentists and can also be used as a simple auxiliary method by physicians; nevertheless, it is still underestimated and more studies are needed.

“…Many studies with OSA patients using the measurements of cephalogram, BMI, and AHI have either been limited to men 9,11,13,18 or included women, but have failed to compare male–female differences 10,17 . On the other hand, Jamison et al 22 compared males and females OSA patients, but there are only 13 female patients compared to 141 male patients, being considered insufficient for comparison between male–female differences.…”

“…Fat deposition around the airway due to obesity is known to be the main cause of OSA, but for Japanese patients, OSA has been seen in around 40% of non‐obese patients with a body mass index (BMI: kg/m 2 ) of <25 5 . Recently, maxillofacial morphology, such as small mandible with retrusion, short oral depth, or low position of the hyoid bone, has been reported to be associated with OSA 8‐20 . However, the subjects in those studies were almost all male patients, so the clinical features of female OSA patients remain unclear.…”

Purpose Obstructive sleep apnea (OSA) is generally more common in men than in women, so many studies have only involved male OSA patients as subjects. However, a certain proportion of OSA patients are female, and few studies have addressed this population. Maxillofacial morphology and obesity are now being shown to be intimately connected with OSA, but the details remain unclear. The objective of this retrospective study was to identify the clinical features of OSA in men and women of different ages, with a focus on maxillofacial morphology and body mass index (BMI). Methods The subjects comprised 112 patients (56 men and 56 women) randomly selected from adult patients in the Niigata University Medical and Dental Hospital. We investigated the results of lateral cephalogram measurements and polysomnography (PSG) conducted before the start of OSA treatment. We then divided the patients by age (with 50 years as the cutoff value) and sex, and performed statistical comparisons among these four groups. Results The findings showed that the hyoid bone was lower in men aged ≥50 compared with <50, and the cross‐sectional area of the tongue was larger. This suggested that aging changes in maxillofacial morphology may be a risk factor in men. In women, however, only slight morphological differences were found between the two age groups. Conclusions This comparative study of sex and age groups in OSA patients suggests that the different groups have different clinical characteristics and may have different risk factors for developing OSA.

“…Regarding the distance from the hyoid bone to the mandibular plane (MP-H), higher values were found in the OSAG when compared with CG. This reflects a lower position of the hyoid bone, which, according to studies, 25 28 30 may be associated with the presence of OSA. The hyoid bone position impacts the tongue shape and position, affecting the airway patency in the hypopharynx.…”

“…31 Therefore, attention should be paid to the increased distance from the hyoid bone, because as the tongue muscles are partly anchored to the hyoid bone, its height can influence the relationship of soft tissues in the oropharynx, facilitating the airway collapse during sleep. 30 …”

Introduction Obstructive Sleep Apnea (OSA) is characterized by repeated episodes of upper airway obstruction during sleep.Objective The objective of this study is to verify the craniofacial characteristics and craniocervical posture of OSA and healthy subjects, determining possible relationships with the apnea/hypopnea index (AHI).Methods This case-control study evaluated 21 subjects with OSA, who comprised the OSA group (OSAG), and 21 healthy subjects, who constituted the control group (CG). Cephalometry analyzed head posture measurements, craniofacial measurements, and air space. Head posture was also assessed by means of photogrammetry.Results The groups were homogeneous regarding gender (12 men and 9 women in each group), age (OSAG = 41.86 ± 11.26 years; GC = 41.19 ± 11.20 years), and body mass index (OSAG = 25.65 ± 2.46 kg/m2; CG = 24.72 ± 3.01 kg/m2). We found significant differences between the groups, with lower average pharyngeal space and greater distance between the hyoid bone and the mandibular plane in OSAG, when compared with CG. A positive correlation was found between higher head hyperextension and head anteriorization, with greater severity of OSA as assessed by AHI.Conclusion OSAG subjects showed changes in craniofacial morphology, with lower average pharyngeal space and greater distance from the hyoid bone to the mandibular plane, as compared with healthy subjects. Moreover, in OSA subjects, the greater the severity of OSA, the greater the head hyperextension and anteriorization.

Correlation between cephalometric data and severity of sleep apnea

Abstract: Cephalometric variables are useful tools for the understanding of obstructive sleep apnea syndrome. The distance from the hyoid bone to the mandibular plane showed a statistically significant correlation with the apnea-hypopnea index.
