Abstract
Cephalometric Indicator of Obstructive Sleep Apnea in Relation to Severity and Sites of Obstruction in Non-Obese Male Patients
Highlights
Obstructive Sleep Apnea syndrome (OSA) is characterized by episodic cessation of breathing during sleep
This study revealed that certain Craniofacial and upper airway soft tissue characteristics exist in relation to severity of OSA and sites of obstruction. (C3-Me perpendicular to the hyoid bone) is a significant predictor of OSA in non-obese Lebanese male subjects
We found a hyper divergent facial type for the two severity groups in comparison to controls (we found decreased Jarabak facial ratio (S-Go/N-Me%): controls mean: 70 ± 0; mild to moderate mean: 66.1 ± 5.7; severe mean: 67.4 ± 6.1) which was in accordance with the findings of Tsai, et al [13] in which greater lower anterior facial height was related to an overall increase in OSA severity in men; and severity of the OSA was related to the lower anterior portion in men in which a larger Y-axis implies more downward mandibular growth and is related to greater lower facial height
Summary
Obstructive Sleep Apnea syndrome (OSA) is characterized by episodic cessation of breathing during sleep. Previous studies by Bacon, et al [3]; Kubota, et al [4]; Lowe, et al [5]; and Lowe, et al [6] investigated facial characteristics of OSA patients in relation to severity and sites of obstruction and found that certain dentofacial characters could be used as diagnostic measures and aid in treatment planning of those patients. International Journal of Dentistry and Oral Health Open Access Journal conducted on obstructive sleep apnea on the Lebanese population and few studies have investigated the relationship between the dentofacial characteristics and obstructive sites in patients with OSA, this justified the conduct of the study since proper diagnosis is the key to understanding the etiology of OSA and the proper treatment plan
