Barbed Suspension of the Tongue Base for Treatment of Obstructive Sleep Apnea Patients


Obstructive sleep apnea syndrome (OSAS) is a common clinical condition in which the throat narrows or collapses repeatedly during sleep, causing obstructive sleep apnea events. One of the most common sites for collapse during sleep is hypo-pharyngeal space. It was founded in 50% of OSA patients those have moderate and severe apnea. DeRowe et al invented the Tongue base suspension operation in 1998 for sleep disordered breathing.
