Headache semiology (according to ICHD-3), frequency, intensity, and radiological characteristics were evaluated pre- and postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We included 65 patients. 38 patients were female and 27 male. Mean age was 43.9\u2009\u00b1\u200915.7 years. Headache was predominant in 41 patients (63.0%). Twenty-one patients had cough headache and 20 had atypical headache (12 migrainous, eight tension-type headache-like). Thirty-five patients with headache underwent surgery. Frequency, intensity, and analgesic use was significantly reduced in cough headache ( p\u2009&lt;\u20090.001). Atypical headaches improved less ( p\u2009=\u20090.004 to 0.176). Exploratory analysis suggested that larger preoperative tonsillar descent correlated with larger postoperative headache intensity relief ( p\u2009=\u20090.025).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Decompression was effective in Chiari I malformation-related cough headache. Atypical headache responded less well, and the causal relation with Chiari I malformation remains uncertain. For atypical headache, decompression should only be considered after failed appropriate preventive therapy and within an interdisciplinary approach involving a neurologist.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/03331024221079296","type":"journal-article","created":{"date-parts":[[2022,3,3]],"date-time":"2022-03-03T00:19:56Z","timestamp":1646266796000},"page":"879-887","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Headache characteristics and postoperative course in Chiari I malformation"],"prefix":"10.1177","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4319-7734","authenticated-orcid":false,"given":"Dennis C","family":"Thunstedt","sequence":"first","affiliation":[{"name":"Department of Neurology, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Schmutzer","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias P","family":"Fabritius","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Thorsteinsdottir","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathias","family":"Kunz","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9510-7158","authenticated-orcid":false,"given":"Ruth","family":"Ruscheweyh","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Straube","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Hospital, Ludwig Maximilians University (LMU), Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,3,2]]},"reference":[{"key":"bibr1-03331024221079296","doi-asserted-by":"crossref","unstructured":"Sarnat HB.
