Surgery by neurosurgeons and orthopedists is a critical treatment for symptomatic patients, and surgical techniques are associated with improved symptoms for these patients. The aim of this study was to determine the different surgical techniques used by neurosurgeons and orthopedists in Japan to treat syringomyelia caused by Chiari I malformation.<\/jats:p><\/jats:sec>\n\nMethods<\/jats:title>\nPatients who had undergone a surgical treatment were identified from a 2-stage postal survey conducted in late 2009. The authors compared the type of surgery performed and its association with cavity size reduction, on the basis of whether patients were receiving care in a neurosurgery or orthopedics department.<\/jats:p><\/jats:sec>\n\nResults<\/jats:title>\nA total of 232 patients with syringomyelia caused by Chiari I malformation were included in this study. Two-thirds of patients were treated in a neurosurgery department and the other third in an orthopedics department. Neurosurgeons preferred foramen magnum decompression (FMD) with dural patch grafting, and orthopedists preferred FMD with dural dissection. Foramen magnum decompression with dural patch grafting was associated with better outcomes than was dural dissection with regard to the following: motor impairment (66% vs 39%, p < 0.05), sensory disturbance (60% vs 43%, p = 0.051), pain (67% vs 47%, p < 0.05), and cavity size (74% vs 58%, p < 0.05). Improved motor function was associated more with cavity size reduction than with sensory disturbance and pain.<\/jats:p><\/jats:sec>\n\nConclusions<\/jats:title>\nSurgical procedures and outcomes differed, depending on whether the patient's care was managed in a neurosurgery or orthopedics department. Outcomes were better after FMD with dural patch grafting.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2013.3.spine12837","type":"journal-article","created":{"date-parts":[[2013,4,19]],"date-time":"2013-04-19T13:59:35Z","timestamp":1366379975000},"page":"588-592","source":"Crossref","is-referenced-by-count":20,"title":["Different surgical treatment techniques used by neurosurgeons and orthopedists for syringomyelia caused by Chiari I malformation in Japan"],"prefix":"10.3171","volume":"18","author":[{"given":"Ken","family":"Sakushima","sequence":"first","affiliation":[{"name":"Departments of Neurology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazutoshi","family":"Hida","sequence":"additional","affiliation":[{"name":"Neurosurgery, Hokkaido University Graduate School of Medicine, Sapporo, Hokkaido; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ichiro","family":"Yabe","sequence":"additional","affiliation":[{"name":"Departments of Neurology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Tsuboi","sequence":"additional","affiliation":[{"name":"Department of Public Health, Jichi Medical University, Simotsuke, Tochigi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ritei","family":"Uehara","sequence":"additional","affiliation":[{"name":"Department of Public Health, Jichi Medical University, Simotsuke, Tochigi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidenao","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Departments of Neurology and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"3 Suppl","key":"b1-spine12837","series-title":"J Neurosurg","first-page":"187","article-title":"The role of limited posterior fossa craniectomy in the surgical treatment of Chiari malformation Type I: experience with a pediatric series","volume":"106","author":"Caldarelli","year":"2007"},{"key":"b2-spine12837","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1775","DOI":"10.1097\/BRS.0b013e3181b07914","article-title":"Neurosurgical management of spinal dysraphism and neurogenic scoliosis","volume":"34","author":"Cardoso","year":"2009"},{"key":"b3-spine12837","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"344","DOI":"10.1136\/jnnp.74.3.344","article-title":"Hypothesis on the pathophysiology of syringomyelia based on simulation of cerebrospinal fluid dynamics","volume":"74","author":"Chang","year":"2003"},{"key":"b4-spine12837","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1451","DOI":"10.1097\/00007632-200207010-00015","article-title":"Chiari I malformation associated with syringomyelia and scoliosis: a twenty-year review of surgical and nonsurgical treatment in a pediatric population","volume":"27","author":"Eule","year":"2002"},{"key":"b5-spine12837","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"281","DOI":"10.1016\/0090-3019(91)90089-R","article-title":"Management of syringomyelia associated with Chiari malformation: comparative study of syrinx size and symptoms by magnetic resonance imaging","volume":"36","author":"Fujii","year":"1991"},{"key":"b6-spine12837","series-title":"Acta Neurochir (Wien)","doi-asserted-by":"publisher","first-page":"134","DOI":"10.1007\/s007010050074","article-title":"Transverse microincisions of the outer layer of the dura mater combined with foramen magnum decompression as treatment for syringomyelia with Chiari I malformation","volume":"140","author":"Gambardella","year":"1998"},{"key":"b7-spine12837","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"247","DOI":"10.1136\/jnnp.28.3.247","article-title":"Hydrodynamic mechanism of syringomyelia: its relationship to myelocele","volume":"28","author":"Gardner","year":"1965"},{"key":"b8-spine12837","series-title":"Childs Nerv Syst","doi-asserted-by":"publisher","first-page":"35","DOI":"10.1007\/s00381-010-1295-7","article-title":"Duraplasty or not?
