In this study, the authors report on application of this robotic device to endoscopic endonasal transsphenoidal surgery (ETSS) and evaluate their initial experiences.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n The study population consisted of 43 patients: 29 with pituitary adenoma, 3 with meningioma, 3 with Rathke\u2019s cleft cyst, 2 with craniopharyngioma, 2 with chordoma, and 4 with other conditions. All patients underwent surgery via the endonasal transsphenoidal approach using a rigid endoscope. During the nasal and sphenoid phases, iArmS was used to support the surgeon\u2019s nondominant arm, which held the endoscope. The details of the iArmS and clinical results were collected.<\/jats:p>\n Results iArmS followed the surgeon\u2019s arm movement automatically. It reduced the surgeon\u2019s fatigue and stabilized the surgeon\u2019s hand during ETSS. Shaking of the video image decreased due to the steadying of the surgeon\u2019s scope-holding hand with iArmS. There were no complications related to use of the device.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The intelligent armrest, iArmS, seems to be safe and effective during ETSS. iArmS is helpful for improving the precision and safety not only for microscopic neurosurgery, but also for ETSS. Ongoing advances in robotics ensure the continued evolution of neurosurgery.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2017.3.focus16498","type":"journal-article","created":{"date-parts":[[2017,5,2]],"date-time":"2017-05-02T15:57:03Z","timestamp":1493740623000},"page":"E10","source":"Crossref","is-referenced-by-count":40,"title":["Endoscopic endonasal transsphenoidal surgery using the iArmS operation support robot: initial experience in 43 patients"],"prefix":"10.3171","volume":"42","author":[{"given":"Toshihiro","family":"Ogiwara","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Shinshu University School of Medicine, Matsumoto, Japan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Goto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinshu University School of Medicine, Matsumoto, Japan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alhusain","family":"Nagm","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinshu University School of Medicine, Matsumoto, Japan; and"},{"name":"Department of Neurosurgery, Al-Azhar University Faculty of Medicine-Nasr City, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiro","family":"Hongo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shinshu University School of Medicine, Matsumoto, Japan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"6 Suppl","key":"b1","series-title":"World Neurosurg","doi-asserted-by":"publisher","first-page":"S3","DOI":"10.1016\/j.wneu.2014.07.019","article-title":"Endoscopic endonasal surgery for pituitary adenomas","volume":"82","author":"Cappabianca P","year":"2014","unstructured":"Cappabianca P, Cavallo LM, Solari D, Stagno V, Esposito F, de Angelis M: Endoscopic endonasal surgery for pituitary adenomas.
