Soft Cervical Collar in Obstructive Sleep Apnea, A Pilot Study
2020
A soft cervical collar is a simple-to-use, non-invasive, non-intrusive, cheap and comfortable external support that can be used after cervical surgery or injuries such as whiplash [1, 2]. It limits cervical and head movements such as antero-posterior flexion/extension and backward motion of the mandible [3, 4]. In obstructive sleep apnea (OSA), upper airway obstruction can be caused by anterior flexion of the head or by backward seesaw motion of the mandible and the tongue in supine position [3, 5–7]. Prior to a randomised controlled trial (RCT) using such a support to treat OSA, we assessed in a pilot study 1) night tolerance of the soft cervical collar in patients with OSA; 2) alteration of pharyngeal patency according to polygraphy data with this support in OSA; 3) trial population size for conclusive results.
