Brief Summary:
Hypoglossal nerve stimulation (HNS) therapy (Inspire system) is intended for the treatment of patients with moderate to severe obstructive sleep apnea (OSA) who cannot be effectively treated with the first-line treatment options.
Approximately 3 months after activation of HNS therapy, a fine-tuning sleep study is performed. To date, the standard of care involves an in-laboratory overnight titration PSG, which assesses the device settings and, if necessary, the stimulation strength will be adjusted based on observed respiratory events and/or snoring. Considering the growing patient population, the performance of these overnight titrations can become logistically challenging and labor-intensive. Recently, the feasibility of using a daytime PSG as an alternative to a conventional overnight PSG for titration of HNS therapy was demonstrated.
The aim of this study is to further investigate this technique by performing a non-inferiority analysis of daytime versus overnight PSG for titration of HNS therapy in patients with OSA.

Detailed Description:
This study is a prospective and retrospective, single-center non-inferiority study. The study population consists of two cohorts: (1) OSA patients treated with HNS that previously underwent an overnight titration PSG as part of the routine clinical care pathway and (2) OSA patients treated with HNS that recently underwent or will be undergoing a daytime titration PSG.
Data collection will include polysomnographic data, home sleep test data, therapy usage, device data and questionnaires (Epworth Sleepiness Scale, Functional Outcomes of Sleep Questionnaire-30, Visual Analogue Scale (VAS) snoring. Data will be collected from different visits including: pre-implant, implant, activation, titration, follow-up (6 and 12 months post-implantation).
