Cone beam computed tomography and obstructive sleep apnoea

Abstract

Sleep apnoea is characterized by an intermittent cessation or diminution of airflow during sleep that may result in significant pulmonary and cardiac consequences, and is associated with significant morbidity and mortality. It is a common disease that affects approximately 20% of patients who snore, equating to a total prevalence in the population of about 4% of all middle aged men and 2% of women. In reality, due to lack of recognition and the difficulty with obtaining an accurate diagnosis, the actual incidence is likely much higher.

Three-dimensional analysis of craniofacial bones and soft tissues in obstructive sleep apnea using cone beam computed tomography

“…Les prises de mesure craniofaciales avec le cone beam sont valides et reproductibles [9,10]. Le cone beam a ete utilise pour evaluer les impactions de canines 3-dimensional analysis of the upper airway while being fast and easy to interpret [11].…”

Application of three‐dimensional computed tomography in craniofacial clinical practice and research

“…Various aspects of cone beam computed tomography (CBCT) image acquisition, interpretation and application to specific disciplines have been described in a recently published special issue of the Australian Dental Journal . In craniofacial clinical practice, CBCT has been indicated for assessment of various types of acquired and congenital craniofacial malformations, such as cleft palate, facial trauma, root fractures, inflammatory bony changes and benign and malignant lesions .…”

Cone beam computed tomography as diagnostic modality in temporomandibular disorders: A report of four cases

“…The conventional cephalometric radiograph, compresses 3D anatomy into a 2D image, whereas CBCT provides a true single plane midline image which eliminates the overlapping of head and neck structures that makes identification and specific anatomic measurements difficult apart from allowing a more precise measurement directly on a 1:1 scale. [15] It is known that digital flat-panel detector (FPDs) are capable to directly convert the energy of X-ray into high spatial resolution digital signal. The advancements in FPD technology resulted in X-ray tubes which require relatively less power and better computing power which has led to wide use of CBCT in multiple biomedical applications and industrial applications such as single-photon emission CT, image guided type of radiotherapy, neuroradiology, angiography, spinal procedures, thoracic procedures, and orthopedic procedures.…”
