The extended transnasal approach allows early decompression of the optic canals, obviates the need for brain retraction, and reduces neurovascular manipulation.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Between 2004 and 2007, 11 consecutive patients underwent transnasal resection of anterior cranial fossa meningiomas\u20144 olfactory groove (OGM) and 7 tuberculum sellae (TSM) meningiomas. Age at surgery, sex, symptoms, and imaging studies were reviewed. Tumor size and tumor extension were estimated, and the anteroposterior, vertical, and horizontal diameters were measred on MR images. Medical records, surgical complications, and outcomes of the patients were collected.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A gross-total removal of the lesion was achieved in 10 patients (91%), and in 1 patient with a TSM only a near-total (> 90%) resection was possible. Four patients with preoperative visual function defect had a complete recovery, whereas 3 patients experienced a transient worsening of vision, fully recovered within few days. In 3 patients (2 with TSMs and 1 with an OGM), a postoperative CSF leak occurred, requiring a endoscopic surgery for skull base defect repair. Another patient (a case involving a TSM) developed transient diabetes insipidus. The operative time ranged from 6 to 10 hours in the OGM group and from 4.5 to 9 hours in the TSM group. The mean duration of the hospital stay was 13.5 and 10 days in the OGM and TSM groups, respectively. Six patients (3 with OGMs and 3 with TSMs) required a blood transfusion. Surgery-related death occurred in 1 patient with TSM, in whom the tumor was successfully removed.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The technique offers a minimally invasive route to the midline anterior skull base, allowing the surgeon to avoid using brain retraction and reducing manipulation of the large vessels and optic apparatus; hastens postoperative recovery; and improves patient compliance. Further assessment and refinement are required, particularly because of the potential risk of CSF leakage. Other studies and longer follow-up periods are necessary to ascertain the benefits of the technique.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/foc.2008.25.12.e8","type":"journal-article","created":{"date-parts":[[2008,11,26]],"date-time":"2008-11-26T11:56:31Z","timestamp":1227700591000},"page":"E8","source":"Crossref","is-referenced-by-count":120,"title":["Endoscopic transnasal resection of anterior cranial fossa meningiomas"],"prefix":"10.3171","volume":"25","author":[{"given":"Enrico","family":"de Divitiis","sequence":"first","affiliation":[{"name":"Department of Neurological Sciences, Division of Neurosurgery, Universit\u00e0 degli Studi di Napoli Federico II, Via Sergio Pansini, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felice","family":"Esposito","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Division of Neurosurgery, Universit\u00e0 degli Studi di Napoli Federico II, Via Sergio Pansini, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Cappabianca","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Division of Neurosurgery, Universit\u00e0 degli Studi di Napoli Federico II, Via Sergio Pansini, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luigi M.","family":"Cavallo","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Division of Neurosurgery, Universit\u00e0 degli Studi di Napoli Federico II, Via Sergio Pansini, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oreste","family":"de Divitiis","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Division of Neurosurgery, Universit\u00e0 degli Studi di Napoli Federico II, Via Sergio Pansini, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella","family":"Esposito","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Division of Neurosurgery, Universit\u00e0 degli Studi di Napoli Federico II, Via Sergio Pansini, Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0250008","series-title":"Meningiomas","first-page":"395","article-title":"Tuberculum sellae meningiomas","author":"Al-Mefty","year":"1991"},{"key":"b2-0250008","series-title":"Surg Neurol","first-page":"37","article-title":"Tuberculum sellae meningiomas: functional outcome in a consecutive series treated microsurgically","volume":"66","author":"Bassiouni","year":"2006"},{"key":"b3-0250008","series-title":"Neurosurgery","first-page":"411","article-title":"The microsurgical nuances of resecting tuberculum sellae meningiomas","volume":"56","author":"Benjamin","year":"2005"},{"key":"b4-0250008","series-title":"Neurosurgery","first-page":"1365","article-title":"Sellar repair in endoscopic endonasal transsphenoidal surgery: results of 170 cases","volume":"51","author":"Cappabianca","year":"2002"},{"key":"b5-0250008","series-title":"Surg Neurol","first-page":"227","article-title":"Sellar repair with fibrin sealant and collagen fleece after endoscopic endonasal transsphenoidal surgery","volume":"62","author":"Cappabianca","year":"2004"},{"key":"b6-0250008","series-title":"Endoscopic Endonasal Transsphenoidal Surgery","first-page":"137","article-title":"Extended endoscopic approaches to the skull base.
