Superior rectus muscle is located in the superior level of the orbital cavity, below <jats:italic>musculus levator palpebrae superioris<\/jats:italic>, tilted slightly to the lateral part of the orbit. In a routine dissection, we found a left, unilateral variation of the superior rectus muscle with no variation in other structures, such as nerves and vessels. The abnormal muscle presented in two parts - medial and lateral ones. The medial part bifurcated into two heads with different insertion points. It is a case of a rare variation of the extraocular muscles, which, to our knowledge, has not yet been reported.<\/jats:p>","DOI":"10.3897\/folmed.65.e79292","type":"journal-article","created":{"date-parts":[[2023,6,30]],"date-time":"2023-06-30T06:39:30Z","timestamp":1688107170000},"page":"514-517","source":"Crossref","is-referenced-by-count":2,"title":["A rare variation of superior rectus muscle"],"prefix":"10.3897","volume":"65","author":[{"given":"Dimo","family":"Stoyanov","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5900-9718","authenticated-orcid":true,"given":"Meglena","family":"Angelova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dessislava","family":"Marinova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2023,6,30]]},"reference":[{"key":"79292_B1","doi-asserted-by":"crossref","unstructured":"1.
