Over centuries, the opponents of this approach highlight the problem of postoperative visual field defect, related to the retraction of occipital lobe. The aim was to describe the surgical nuances of gravity-assisted retractor-less occipital-transtentorial approach (GAROTA) as a modification of originally described GAROTA to minimize the complications with a similar ease of surgery.<\/jats:p><\/jats:sec>Methods:<\/jats:title>In this study, we have retrospectively analyzed our prospectively maintained surgical databases of patients operated by occipito-transtentorial from 2015 to 2019. Demographic variables, preoperative and postoperative neurological deficits (especially visual field defect) were analyzed. Radiological data included relation of veins with tumor, presence of hydrocephalus, size, and extent of lesion.<\/jats:p><\/jats:sec>Results:<\/jats:title>Fifteen patients underwent GAROTA (right-sided extension,n<\/jats:italic>= 7; left-sided extension,n<\/jats:italic>= 4; and midline lesions,n<\/jats:italic>= 4). Headaches (73.3%) and diplopia (40%) were the most common symptoms. No patient had any postoperative visual deficits in both short-term and long-term follow-up.<\/jats:p><\/jats:sec>Conclusion:<\/jats:title>A thorough anatomical knowledge of posterior third interhemispheric region in the semi-prone position is required for GAROTA. Meticulous arachnoid dissection around the deep venous complex and release of cerebrospinal fluid through the cisterns is required. Postoperative cortical vision loss may be prevented by following the key surgical principles in GAROTA.<\/jats:p><\/jats:sec>","DOI":"10.25259\/sni_425_2020","type":"journal-article","created":{"date-parts":[[2020,11,18]],"date-time":"2020-11-18T11:30:07Z","timestamp":1605699007000},"page":"399","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Venous
