Abstract
Objective(s): Hypoglossal nerve stimulation (HGNS) is safe and effective for patients with Down syndrome (DS) and severe persistent obstructive sleep apnea (OSA). Long-term outcomes for this patient population have not been evaluated.
Methods: A prospective single-group multicenter cohort study with 1-year follow-up was conducted between 2015 and 2021 among 42 adolescent patients with DS and severe persistent OSA. Here, we evaluate long-term outcomes in this patient cohort. Patients were evaluated with polysomnogram (PSG) at three timepoints: pre-implantation (timepoint 1), 1-year post-implantation (timepoint 2), and long-term follow-up (timepoint 3).
Results: Long-term follow-up data were available for 33 of 42 patients. Mean (SD) of timepoint 3 was 4.0 (1.9) years after implantation. Using a therapy response definition of a 50% decrease in Apnea Hypopnea INdez (AHI) from timepoint 1, the response rate was 69.7% (23/33) at timepoint 2 and 87.9% (29/33) at timepoint 3. From timepoint 1, there was a mean (SD) decrease in AHI of 12.7 (13.4) events/h at timepoint 2 and 15.7 (13.1) events/h at timepoint 3. The mean percentage change in AHI between timepoints 1 and 2 was -51.1% (95% CI: -32.8% to -69.3%) and between timepoints 1 and 3 was -59.6% (95% CI: -42.0% to -77.3%).
Conclusion: Patients with DS and severe persistent OSA who undergo HGNS implantation may continue to experience improvement in PSG parameters at long-term follow-up. Future studies are needed to assess additional long-term outcomes in this patient population, including neurocognition and quality of life.
期刊介绍：
The Laryngoscope has been the leading source of information on advances in the diagnosis and treatment of head and neck disorders since 1890. The Laryngoscope is the first choice among otolaryngologists for publication of their important findings and techniques. Each monthly issue of The Laryngoscope features peer-reviewed medical, clinical, and research contributions in general otolaryngology, allergy/rhinology, otology/neurotology, laryngology/bronchoesophagology, head and neck surgery, sleep medicine, pediatric otolaryngology, facial plastics and reconstructive surgery, oncology, and communicative disorders. Contributions include papers and posters presented at the Annual and Section Meetings of the Triological Society, as well as independent papers, "How I Do It", "Triological Best Practice" articles, and contemporary reviews. Theses authored by the Triological Society’s new Fellows as well as papers presented at meetings of the American Laryngological Association are published in The Laryngoscope.
