Abstract The Nastent® (Nastent, Inc., Tokyo) is a nasal airway stent (NAS) released in July 2014 for the management of obstructive sleep apnea syndrome (OSAS), but there are few reports on the tolerability and effectiveness of this NAS. The purpose of this study was to assess the tolerability and evaluate the effectiveness of using a NAS in OSAS management in our clinic. In this study, out-of-center sleep testing (OCST) using Watch-PAT® was performed with and without insertion of a NAS or OA (oral appliance). The testing revealed no marked difference in the sleeping time by the insertion or lack of a NAS or OA, and some patients were able to wear a NAS for a long period of time 17.4 ± 20.9 months (0.1 to 52 months), with significant improvements noted in the snoring index and lowest SpO2 (saturation of percutaneous oxygen) with a NAS. As a result, OSAS therapeutic approaches other than the NAS were selected for 6 (54.5%) subjects who wanted to use a NAS. In conclusion, the present study indicates that it is necessary to explain the possibility that the use of a NAS may not always achieve satisfactory results and we therefore recommend OCST with and without the insertion of a NAS.

In conclusion, the present study indicates that it is necessary to explain the possibility that the use of a NAS may not always achieve satisfactory results and we therefore recommend OCST with and without the insertion of a NAS. ナステント®(ナステント株式会社 東京都、以下 NAS)は 2014 年 7 月に発売されたが、その忍容性や、OSAS への効果についての報告は少ない。そこで当診療所での NAS の使用経験から、NAS の忍容性を評価し、OSAS への効果の検討を行った。本検討では簡易型睡眠検査機器である Watch-PAT®(Itamar Medical Caesarea, Israel)を用いて NAS またはマウスピース装用前後で睡眠検査を行い比較検討した。NAS 装用前後で睡眠時間の短縮はなく、一部の患者では長期に NAS 装用が可能であり、NAS 装用前後でいびき(%)と最低 SpO2値において有意な改善がみられた。重要な結果として、NAS 装用希望者中 6 例(54.5%)に NAS 以外の治療方針が選択された。結論として、NAS 装用を希望する患者には効果が得られない可能性を説明し、装用前後の効果確認を勧めることが必要と考えられた。
