The authors question whether this is always true and analyze their series of cases of endoscope-assisted transcranial TSM surgery with special regard to the postoperative visual outcome in order to explore this issue.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>All surgical procedures for TSM performed between 2003 and 2015 in the Department of Neurosurgery, University Medicine Greifswald, were retrospectively analyzed. Special attention was paid to the postoperative visual outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>During the study period, 15 patients (12 female and 3 male) underwent surgery for TSM. Gross-total resection was achieved in 14 cases (93.3%) and near-total resection in 1. One patient suffered from a major stroke during surgery and had to be excluded from further analyses. No other complications occurred. Preoperatively, visual acuity was disturbed in 12 patients (80%) and visual field deficits were present in 11 patients (73.3%). In 3 patients (20%), the TSM was an incidental finding. Postoperatively, ophthalmological examination revealed an improvement of visual acuity in 10 (90.9%) of 11 patients and improvement of visual field deficits in 9 (90%) of 10 patients; no deterioration of visual acuity or visual field was seen in any patient. Visual acuity and visual field improvement was observed in all patients who had surgery within 3 years after the onset of visual disturbances. No tumor recurrence was observed during follow-up (mean 32 months, range 3\u2013134 months). TSMs were approached via a frontolateral craniotomy in 7 patients and via a supraorbital craniotomy in 8. The use of the endoscope as an assistive device led to improved tumor visualization and consequent removal in areas that were hidden in the microscopic view in 6 patients (40%).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The present series confirms a favorable visual outcome after TSM surgery via supraorbital or frontolateral endoscope-assisted approaches. With endoscopic visualization, major manipulation of the optic apparatus could be avoided, perhaps affecting the favorable visual outcome.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2016.11.jns16713","type":"journal-article","created":{"date-parts":[[2017,4,7]],"date-time":"2017-04-07T14:03:49Z","timestamp":1491573829000},"page":"32-39","source":"Crossref","is-referenced-by-count":29,"title":["The value of endoscope assistance during transcranial surgery for tuberculum sellae meningiomas"],"prefix":"10.3171","volume":"128","author":[{"given":"Sascha","family":"Marx","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Clemens","sequence":"additional","affiliation":[{"name":"Ophthalmology, University Medicine Greifswald, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henry W.
