An endonasal transsphenoid transpterygoid approach was done to the superior orbital fissure and annulus of Zinn medially, down to the maxillary nerve. The periorbita was dissected superolaterally to expose the greater wing of the sphenoid and the meningo-orbital band. The superior orbital fissure was decompressed inferiorly by drilling the greater wing of the sphenoid and the maxillary strut after transposition of the maxillary nerve. The meningoorbital band was cut at the junction of the lateral part of the superior orbital fissure and the periorbita exposing the frontotemporal dural junction. The edge of the lesser wing of the sphenoid was drilled toward the annulus of Zinn and the optic canal. The temporal lobe dura was separated from the periorbita and lateral cavernous dural wall at the meningo-orbital band and the ophthalmic nerve.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The superior orbital fissure had an oblique angle (mean: 39 \u00b1 2.75 degrees) to the midsagittal plane, the length of its lateral part corresponding to the meningo-orbital band was (mean: 6.08 \u00b1 2.58 mm) and the distance from its lateral end to midline was (mean 2.97 \u00b1 0.11 cm). The meningo-orbital band was released in 10 cadaveric head sides with a distinct plane between the periorbita and the dura propria. Transmaxillary endoscopy provided less orbital retraction and better visualization of the lateral wall of the cavernous sinus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Endonasal transmaxillary release of the meningoorbital band is feasible, allowing exposure of the orbital apex and the middle cranial fossa.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0028-3886.355088","type":"journal-article","created":{"date-parts":[[2022,9,26]],"date-time":"2022-09-26T00:36:16Z","timestamp":1664152576000},"page":"1427-1434","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Endoscopic Transnasal Transmaxillary Approach to Orbital Apex through the Meningo-Orbital Band: A Cadaveric Feasibility Study"],"prefix":"10.4103","volume":"70","author":[{"given":"Sameh M.","family":"Amin","sequence":"first","affiliation":[{"name":"Otorhinolaryngology and Skull Base Surgery, Fayoum University, Fayoum, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed M.","family":"Talat","sequence":"additional","affiliation":[{"name":"Suez Canal University Hospital, Ismailia, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad S.","family":"Mahmoud","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Ain Shams University Faculty of medicine, El Demerdash Hospital, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashraf Abdellatif","family":"Osman","sequence":"additional","affiliation":[{"name":"Neurosurgery, Faculty of Medicine, Fayoum University, Fayoum, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayman","family":"Hussein","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Faculty of Medicine, Cairo University, Egypt Kasr El Aini Hospital, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Hegazy","sequence":"additional","affiliation":[{"name":"Neurosurgery Faculty of Medicine, Kasr Al-Aini - Cairo University, Abd El-Aziz Basha Fahmy, Giza, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arundhati","family":"Biswas","sequence":"additional","affiliation":[{"name":"Neurosurgery, Carle Foundation Hospital, Urbana, Illinois, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamdi Nabawi","family":"Mostafa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Faculty of Medicine, Misr University for Science and Technology, Al- Motamayez District, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,8,30]]},"reference":[{"key":"R1-20250921","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1055\/s-0033-1359302","article-title":"The meningo-orbital band: Microsurgical anatomy and surgical detachment of the membranous structures through a frontotemporal craniotomy with removal of the anterior clinoid process","volume":"75","author":"Fukuda","year":"2014","journal-title":"J Neurol Surg B Skull Base"},{"key":"R2-20250921","article-title":"Anatomical meningo-orbital band evaluation and clinical implications: a cadaveric dissection study","author":"Anania","year":"2019","journal-title":"J Neurosurg Sci"},{"key":"R3-20250921","doi-asserted-by":"crossref","first-page":"147","DOI":"10.1227\/NEU.0000000000000599","article-title":"Quantitative analysis of variable extent of anterior clinoidectomy with intradural and extradural approaches: 3-dimensional analysis and cadaver dissection","volume":"11","author":"Tripathi","year":"2015","journal-title":"Oper Neurosurg"},{"key":"R4-20250921","doi-asserted-by":"crossref","first-page":"837","DOI":"10.3171\/jns.1991.74.5.0837","article-title":"The Dolenc technique for cavernous sinus exploration (cadaveric prosection).
