Case in brief

Four patients with obstructive sleep apnea who had undergone hypoglossal nerve stimulation implantation experienced a return of symptoms, including increased snoring and reduced tongue sensation during device activation. Diagnostic impedance testing revealed elevated values on bipolar electrode settings. Following electrode reprogramming, the patients regained therapeutic benefits from the device.

Diagnostic / clinical pearl

Clinicians should consider electrode malfunction in patients with hypoglossal nerve stimulation who report a resurgence of obstructive sleep apnea symptoms after initial improvement.
