Summary

This study was designed to explore how the glossopharyngeal nerve varies in shape and size, and whether electrically stimulating it could open the airway during surgery. It planned to enroll adults with head and neck cancer or sleep apnea, but was withdrawn before any participants were recruited. No results are available.
