Surgical resection is the gold standard and a definitive solution. The choice of approach varies between different possibilities, including orbitotomies, trans-sinusal routes, and transconjunctival accesses.\n                    <jats:sup>2-4<\/jats:sup>\n                    Because the last technique is less known to the neurosurgeon, we describe here a step-by-step guide to perform it.\n                  <\/jats:p>\n                  <jats:p>\u2003The technique is illustrated with the case of a 62-yr-old male with a voluminous right retroocular cavernoma. He presented a progressive right exophthalmia without visual acuity or campimetric deterioration. Because the cavernoma was purely medial from the optic nerve in the intraconal space, no osteotomy was deemed necessary to extirpate the lesion. The video shows the conjunctival dissection, followed by the medial rectus muscle being dissected, allowing us to attain the retrobulbar space in the orbit. The cavernoma is then dissected from the surroundings and reduced in volume by coagulation so its removal does not apply hyperpressure on the adjacent fragile structures. We then pursue with the closure by stitching the medial rectus muscle to the eyeball. Finally, the conjunctiva is sutured.<\/jats:p>\n                  <jats:p>\u2003Postoperatively, there was no complication. A transient mydriasis due to ciliary nerve manipulation spontaneously resolved. Extirpation of the lesion was total. The patient's exophthalmia normalized over the next months. No visual or campimetric deterioration was noted at follow-up. A slight horizontal diplopia was noted after surgery, which normalized at 1 yr. The patient's consent was obtained for the procedure.<\/jats:p>","DOI":"10.1093\/ons\/opaa312","type":"journal-article","created":{"date-parts":[[2020,10,9]],"date-time":"2020-10-09T12:34:34Z","timestamp":1602246874000},"page":"E134-E135","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Transconjunctival Extirpation of a Voluminous Orbital Cavernoma: 2-Dimensional Operative Video"],"prefix":"10.1227","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6977-830X","authenticated-orcid":false,"given":"Adrien T","family":"May","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Geneva University Hospitals, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramona","family":"Guatta","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Geneva University Hospitals, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Torstein R","family":"Meling","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Geneva University Hospitals, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,2]]},"reference":[{"issue":"4","key":"bib1-20251027","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1016\/j.survophthal.2017.01.004","article-title":"Cavernous venous malformation (cavernous hemangioma) of the orbit: current concepts and a review of the literature","volume":"62","author":"Calandriello","year":"2017","journal-title":"Surv Ophthalmol"},{"key":"bib2-20251027","doi-asserted-by":"crossref","first-page":"1","DOI":"10.3389\/fsurg.2020.00001","article-title":"Cranio-orbital and orbitocranial approaches to orbital and intracranial disease: eye-opening approaches for neurosurgeons","volume":"7","author":"Abou-Al-Shaar","year":"2020","journal-title":"Front Surg"},{"issue":"6","key":"bib3-20251027","doi-asserted-by":"crossref","first-page":"1991","DOI":"10.1097\/SCS.0b013e3182a28c0b","article-title":"The transconjunctival approach a minimally invasive approach to various kinds of retrobulbar tumors","volume":"24","author":"Park","year":"2013","journal-title":"J Craniofac Surg"},{"key":"bib4-20251027","article-title":"Endoscopic approaches to orbital lesions: case series and systematic literature review. published online: January 3, 2020","author":"Zoli","journal-title":"J Neurosurg"}],"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ons\/advance-article-pdf\/doi\/10.1093\/ons\/opaa312\/33857538\/opaa312.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opaa312","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T16:59:29Z","timestamp":1786121969000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opaa312"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,10,9]]},"references-count":4,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.1093\/ons\/opaa312","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,10,9]]},"assertion":[{"value":"2020-03-25","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-08-02","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
