“…The lateral cephalogram (LC) is considered a standard tool for maxillofacial surgeons to predict treatment interventions and quantify the changes of airway structure before and after the use of mandibular advancement devices or maxillomandibular advancement surgery treatments. 1,2 LC generates two-dimensional (2D) images of a three-dimensional (3D) structure and suffers from distortion, magnification, lack of transverse dimensions, and superimposition of bilateral craniofacial structures, 3,4 which render an inadequate size and a complexity of airway structure assessments. However, LC measurements provide the ability to differentiate between OSA and non-OSA patients and have been correlated with the severity of the disorder.…”

No strong correlations were reported between the LC and CT scans. However, the LC-derived adenoid-nasopharyngeal ratio and the linear measurement (posterior nasal spine, PNS, to posterior pharyngeal wall) had a strong correlation with upright nasopharyngeal area and volume in the CBCTs. The area measurement in conventional LC can be also used as an initial screening tool to predict the upright three-dimensional oropharyngeal volumetric data. The variability of the hypopharyngeal segment cannot be predicted by LCs. However, more well-designed studies are needed to determine the clinical utility of using LC to predict airway size.

“…The differential diagnosis of upper airway obstruction includes neoplasms, parapharyngeal abscess, and infection (e.g., tonsillitis, laryngitis, and cellulitis) and these should be excluded by the imaging findings, laboratory data, clinical course, and laryngoscopy [14, 15]. Glossomegaly may also be seen in patients with amyloidosis (Fig.…”

ObjectivesThe purpose of this pictorial review is to present imaging findings of angioedema involving the various organs.ConclusionThe role of imaging for patients with angioedema includes the evaluation of the upper airway for obstruction and the exclusion of other possible aetiologies, such as neoplastic or infectious processes. Glossomegaly is a common finding of head and neck angioedema. Angioedema may involve organ systems beyond the superficial regions and the head and neck including the gastrointestinal and genitourinary tracts. Angioedema of the visceral organs is often accompanied by adjacent fluid, and it is commonly diffuse or concentric but can also be multifocal and asymmetric.Teaching PointsThe evaluation of the upper airway obstruction is important for head and neck angioedema.Glossomegaly with decreased attenuation is common in head and neck angioedema.Angioedema of the visceral organs can be multifocal and asymmetric.Angioedema of the visceral organs is often accompanied by adjacent fluid.It is important to include clinical and laboratory findings for the diagnosis of angioedema.

“…But some cephalometric parameters can accept a signal for OSAS risk. Increased mandibular plane angle, steep occlusal plane, over-erupted posterior dentition, large gonial angle, anterior open bite, adipose tissue placed in the submental and parapharyngeal region, larger and wider soft palate, and increased linear distance from the mandibular plane to the hyoid bone (a distance bigger than 15.4 mm) create OSA risk [10,13].…”

Upper airway diseases decrease sleep time and/or quality, which leads to excessive day time sleepiness, fatigue, and lack of concentration. Upper airway diseases can be classified into two groups: upper airway resistance syndrome and sleep apnea syndrome. Sleep apnea syndrome is a disease, which occurs during sleeping, characterized by apneic and hypopneic events, low oxygen levels in lungs, blood oxygen desaturation, sleep arousal, and/or awakening. It increases morbidity and mortality of the patients. Sleep apnea syndrome has three types: central, mixed, and obstructive. Central and mixed apnea can be treated only by medical practitioners. But in the treatment of obstructive sleep apnea, orthodontists and maxillofacial surgeons have an important role. The aim of this chapter is to present current information about etiology, diagnostic tools, and treatment alternatives of obstructive sleep apnea and to introduce dental sleep medicine to orthodontists.
