Novel Outcome Analysis Tool for Hypoglossal Nerve Stimulator Sensor Lead Function and Comparison by Incision Type (2...

Area of Science:

• Medical Devices
• Neurosurgery
• Sleep Medicine

Background:

• No established outcome measures exist for evaluating hypoglossal nerve stimulator (HNS) sensor lead function.
• Developing reliable methods to assess HNS performance is crucial for patient care and device optimization.

Purpose of the Study:

• To develop novel functional outcome measures for intraoperative sensor electrode function in HNS.
• To compare the outcomes of 2-incision versus 3-incision techniques for HNS placement based on these new measures.

Main Methods:

• Retrospective cohort study of 100 HNS patients.
• Development of structured parameters to analyze intraoperative waveforms (syncing, amplitude, leakage, morphology, artifact, overall impression).
• Blinded assessment of waveforms by sleep surgeons and specialists using a Likert scale.

Main Results:

• No significant differences in patient demographics or major complications between 2-incision and 3-incision groups.
• High interrater reliability (>0.7 ICC) for the developed outcome measures.
• The 2-incision technique demonstrated statistically better waveform syncing and overall impression compared to the 3-incision technique.

Conclusions:

• This study presents the first structured method for measuring HNS sensor electrode outcomes with consistent interrater reliability.
• The findings support the adoption of the 2-incision technique for HNS sensor lead placement.
• The developed outcome measures represent a valuable tool for clinical and research settings, requiring further validation.
