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

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.

Kane et al. (2026) studied this question.
