Comparison of the Effect of the Jaw Thrust Maneuver, Chin Lift, Head Rotation, and Tongue Protrusion on the Obstruction of Different Levels of the Upper Airway During the Drug-Induced Sleep Endoscopy: A Cross-Sectional Study

AbstractTo determine the impact of four maneuvers (Jaw Thrust, Chin Lift, Head Rotation, and Tongue Protrusion) on the degree of airway collapse at different airway levels during drug-induced sleep endoscopy (DISE) compared with natural supine position (regular) DISE and evaluate the association of each maneuver with polysomnographic findings compared with regular DISE without any maneuver. One hundred and nine OSA patients aged 20 to 55 who were candidates for sleep surgery were included. The association of the Apnea Hypopnea Index (AHI) with the degree of obstruction during four maneuvers of DISE and regular DISE was evaluated. AHI is significantly predicted by degree of obstruction at the velum (regular DISE) ( β = 10.213), oropharynx (regular DISE) (β = 7.979), velum (jaw thrust DISE) (β = 12.286), oropharynx (jaw thrust DISE) (β = 8.430), velum (head rotation DISE) (β = 10.357), and velum (chin lift DISE) (β = 10.781). In the multivariate model, AHI was predicted by the velu m during the jaw thrust maneuver (β = 7.985). Velum obstruction during DISE with jaw thrust, closing, and rotation maneuvers can significantly predict AHI. The degree of velum collapse during the jaw thrust maneuver is the most reliable and independent finding that correlates with the severity of obstructive sleep apnea.
