However its relevance and prognostic significance are not known.\nObjective: To evaluate patients of TBI with tentorial hematoma using a simple grading system and attempt to correlate this grading with factors like helmet use and neurological outcome. \nMaterials and Methods: This prospective study over a 1-year period included patients with TBI who had tentorial hematoma in the initial plain head. Patients were divided into three grades based on the initial CT findings: Grade I: Isolated tentorial hematoma, grade II: tentorial hematoma with midline shift but open cisterns and grade III: Tentorial hematoma with effaced cisterns. Clinical and radiological records of patients including admission GCS and GOS at discharge were assessed in all cases.\nObservations: A total of 1786 patients of TBI were admitted during the study period. Of these, 106 (5.9%) patients had tentorial hematoma. 84.9% (n = 90) were male and 15.1% (n = 16) were female with the mean age being 36.5 years (range 2-66 years). The mean admission GCS was 13, 11 and 8 in patients with grade I, II and III tentorial hematoma respectively. 43.4% (n = 46) of the patients had grade I, 32.1% (n = 34) had grade II and 24.5% (n = 26) patients had grade III tentorial hematoma. Seventy-one patients (84.5%) were riding motorized two wheelers with 63 (89%) wearing helmets. The majority of the patients wearing helmets (58.8%) had grade I hematoma with 35% (n = 22) having grade II hematoma and only 6.3% (n = 4) having grade III hematoma. Overall, there were 20 deaths. 50% (n = 10) of the deaths were in patients with grade III hematoma and 40% (n = 8) of the deaths were in patients with grade II hematoma. There were two (10%) deaths in patients with grade I hematoma (both unrelated to head injury). The mean GOS at the time of discharge was 5, 4.1 and 2.2 in patients with grade I, II and III tentorial hematoma, respectively. Conclusions: Tentorial hematomas are very common in two-wheeler riders with TBI and could be a marker for indirect forces such as rotational forces experienced while wearing helmets.<\/jats:p>","DOI":"10.4103\/1793-5482.144182","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T07:09:46Z","timestamp":1415344186000},"page":"392-395","source":"Crossref","is-referenced-by-count":1,"title":["Traumatic tentorial hematoma in two-wheeler riders: Correlation with helmet use"],"prefix":"10.1055","volume":"11","author":[{"given":"Deepak","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, JPN Apex Trauma Centre, All India Institute of Medical Sciences, New Delhi"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pankaj","family":"Dawar","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, JPN Apex Trauma Centre, All India Institute of Medical Sciences, New Delhi"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"key-10.4103\/1793-5482.144182-1","first-page":"949","volume-title":"Head injury mechanisms in helmet-protected motorcyclists: Prospective multicenter study","author":"Richter","year":"2001","journal-title":"J Trauma"},{"key":"key-10.4103\/1793-5482.144182-2","first-page":"259","volume-title":"Acute infratentorial traumatic subdural hematoma associated with a torn tentorium cerebelli in a one-year-old boy","author":"Vielvoye","year":"1982","journal-title":"Neuroradiology"},{"key":"key-10.4103\/1793-5482.144182-3","first-page":"441","volume-title":"Motorcycle-related injuries: Effect of age on type and severity of injuries and mortality","author":"Talving","year":"2010","journal-title":"J Trauma"},{"key":"key-10.4103\/1793-5482.144182-4","first-page":"1141","volume-title":"Youth motorcycle-related hospitalizations and traumatic brain injuries in the United States in 2006","author":"Weiss","year":"2010","journal-title":"Pediatrics"},{"key":"key-10.4103\/1793-5482.144182-5","first-page":"1149","volume-title":"Youth motorcycle-related brain injury by state helmet law type: United States, 2005-2007","author":"Weiss","year":"2010","journal-title":"Pediatrics"},{"key":"key-10.4103\/1793-5482.144182-6","first-page":"2683","volume-title":"Findings on youth injuries bolster case for helmet use by all motorcycle riders","author":"Mitka","year":"2010","journal-title":"JAMA"},{"key":"key-10.4103\/1793-5482.144182-7","first-page":"573","volume-title":"Impact of motorcycle helmets and state laws on society's burden: A national study","author":"Adeleye","year":"2010","journal-title":"Ann Surg"},{"key":"key-10.4103\/1793-5482.144182-8","first-page":"1101","volume-title":"An evidence-based review: Helmet efficacy to reduce head injury and mortality in motorcycle crashes: EAST practice management guidelines","author":"MacLeod","year":"2010","journal-title":"J Trauma"},{"key":"key-10.4103\/1793-5482.144182-9","first-page":"1;CD004333","volume-title":"Helmets for preventing injury in motorcycle riders","author":"Liu","year":"2008","journal-title":"Cochrane Database of Systematic Reviews"},{"key":"key-10.4103\/1793-5482.144182-10","first-page":"393","volume-title":"Motorcyclists' reactions to safety helmet law: A qualitative study","author":"Zamani-Alavijeh","year":"2009","journal-title":"BMC Public Health"},{"key":"key-10.4103\/1793-5482.144182-11","first-page":"1137","volume-title":"Bridging veins on the tentorial surface of the cerebellum: A microsurgical anatomic study and operative considerations","author":"Ueyama","year":"1998","journal-title":"Neurosurgery"},{"key":"key-10.4103\/1793-5482.144182-12","first-page":"363","volume-title":"Tentorial venous sinuses: An anatomic study","author":"Muthukumar","year":"1998","journal-title":"Neurosurgery"}],"container-title":["Asian Journal of Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.4103\/1793-5482.144182.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T23:13:36Z","timestamp":1663715616000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.4103\/1793-5482.144182"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,12]]},"references-count":12,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2022,9,20]]},"published-print":{"date-parts":[[2016,12]]}},"URL":"https:\/\/doi.org\/10.4103\/1793-5482.144182","archive":["Portico","CLOCKSS"],"relation":{},"ISSN":["1793-5482","2248-9614"],"issn-type":[{"value":"1793-5482","type":"print"},{"value":"2248-9614","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,12]]}}}
