Overview

Case report shows cervical osteophyte causing airway blockage in obstructive sleep apnea, highlighting evaluation importance.

Key Points

  • To report a rare case of obstructive sleep apnea caused by a cervical osteophyte rather than typical soft tissue collapse.
  • A 79-year-old man with severe OSA and BMI of 32.9 kg/m² underwent nasal pharyngoscopy and CT scan.
  • Drug-induced sleep endoscopy (DISE) was performed to locate the site of upper airway obstruction.
  • Hypoglossal nerve stimulation was proposed as a potential treatment after evaluating surgical options.
  • The patient experienced severe OSA with an apnea-hypopnea index of 39.8 events/hour.
  • DISE revealed epiglottic collapse against the cervical osteophyte as the sole obstruction.
  • Continuous positive airway pressure (CPAP) restored airflow but did not alleviate choking sensation due to epiglottic placement.
