However, the crowding of a small corridor and two-dimensional viewing restrict this access portal.<\/jats:p><jats:p>\n          Design\u2003Cadaveric qualitative study to assess the feasibility of transorbital microsurgery (TMS).<\/jats:p><jats:p>\n          Setting\u2003Anatomical dissection steps and instrumentation were recorded for homogeneous methodology.<\/jats:p><jats:p>\n          Participants\u2003Six cadaveric specimens were systematically dissected using TMS to the anterior cranial fossa and paramedian structures.<\/jats:p><jats:p>\n          Main Outcome Measures\u2003Anatomical parameters of the TMS craniectomy were established, and the visible and accessible neuroanatomy was highlighted.<\/jats:p><jats:p>\n          Results\u2003A superior lid crease incision achieved essential orbital rim exposure and preseptal dissection. The orbital roof craniectomy is defined by three boundaries: (1) frontozygomatic suture to the frontosphenoid suture, (2) frontal sinus and cribriform plate, and (3) frontal sinus and orbital rim. The mean (standard deviation) craniectomy was 440\u2009mm2 (78\u2009mm2). Exposing the ipsilateral optic nerve and internal carotid artery obviated the need for frontal lobe retraction to identify the A1\u2013M1 bifurcation as well as near-complete visualization of the M1 artery.<\/jats:p><jats:p>\n          Conclusion\u2003TMS is a feasible corridor for intracranial access. Mobilization of orbital contents is imperative for maximal intracranial access and protection of the globe. TMS enables access to the frontal lobe base, ipsilateral optic nerve, and most of the ipsilateral anterior circulation. This cosmetically satisfactory approach causes minimal destruction of the anterior skull base with satisfactory exposure of the anterior cranial fossa floor without sinus invasion.<\/jats:p>","DOI":"10.1055\/s-0043-1772202","type":"journal-article","created":{"date-parts":[[2023,9,4]],"date-time":"2023-09-04T23:02:05Z","timestamp":1693868525000},"page":"470-480","source":"Crossref","is-referenced-by-count":3,"title":["Transorbital Microsurgery: An Anatomical Description of a Minimally Invasive Corridor to the Anterior Cranial Fossa and Paramedian Structures"],"prefix":"10.1055","volume":"85","author":[{"given":"Lena Mary","family":"Houlihan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Loyal and Edith Davis Neurosurgical Research Laboratory, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thanapong","family":"Loymak","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Loyal and Edith Davis Neurosurgical Research Laboratory, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irakliy","family":"Abramov","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Loyal and Edith Davis Neurosurgical Research Laboratory, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed A.","family":"Labib","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Loyal and Edith Davis Neurosurgical Research Laboratory, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael G.
