Obstructive sleep apnea (OSA) is characterized by temporary cessation of breathing (apnea) or shallow breathing (hypopnea) with accompanying hemoglobin oxygen desaturation,resultant restriction and obstruction of respiration, sympathetic neural activation,increased blood pressure and repetitive cerebral arousals for 10 seconds or longer (1). The signs and symptoms of repeated apneic and hypopnea episodes during sleep include excessive daytime sleepiness, night sweats, dry mouth, confusion, impotence, headaches, reduced attention span, and poor job or school performance as well as certain cardiovascular sequelae, such as hypertension and coronary artery...

A total of 161 patients (92 patients with and 79 patients without OSAS) who were ranging in age from 18 to 81 years who had craniofacial CBCT scans were retrospectively investigated. CBCT scans were made with Newtom 3G and 5G (Quantitative Radiology s.r.l., Verona, Italy) (Figure 1).All images were recorded at 120 kVP and 3-5 mA using a 12-inch field of view, an axial slice thickness of 0.3 mm and isotropic voxels. X-ray parameters of kV and mA are automatically determined from scout views by...

On 92 % of the CBCTs, incidental findings were found in normal patients. The most prevalent were airway/sinus findings (64%), followed by, nasal septum deviation, middle ear and mastoid opacification, suggestive for otitis media or mastoiditis (5%), abnormal vertebral anatomy (4.9%). Sialothiasis were detected on 2 patients (1 submandibular, 1 parotid gland) incidentally. We also evaluated the maxillary sinus pathology and figured out the mucous retention cyst and thickening of the mucosa are the most encountered pathologies that can be seen incidentally on maxillary sinuses....

Obstructive sleep apnea syndrome ( OSAS) is a common disorder affecting 2–4% of males and 1– 3% of females in middle-age. It is characterized by repetitive episodes of airway obstruction that result in decreased air flow despite ongoing respiratory efforts during sleep (12-13). Anatomy, pharyngeal dilator muscle function during sleep, and ventilatory control instability are all factors contributing to OSAS pathogenesis and each mechanism (or group of mechanisms) likely has variable importance in predisposing to (or protecting from) development of OSAS (12- 14). Studies investigating...
