The artery is located at mean depths of 21.6 mm at the oral commissure and 8.9 mm at the nasal ala. The angular artery was lateral to the nasolabial sulcus in 100% of cases; the smallest distance between the artery and the nasolabial sulcus was at the oral commissure (11.91 [7.9] mm) and the greatest was at the nasal ala (13.73 [3.9] mm).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>In contrast to current concepts, the angular artery is not located strictly subdermal to the nasolabial sulcus but at a variable depth, and in 100% of the investigated cases lateral to the nasolabial sulcus. With increasing age, the depth and lateral distance between arteries and sulci reduces significantly, underscoring the need for special caution when injecting this site.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/asj\/sjaa152","type":"journal-article","created":{"date-parts":[[2020,6,6]],"date-time":"2020-06-06T13:10:36Z","timestamp":1591449036000},"page":"697-704","source":"Crossref","is-referenced-by-count":25,"title":["Three-Dimensional Description of the Angular Artery in the Nasolabial Fold"],"prefix":"10.1093","volume":"41","author":[{"given":"Pavel","family":"Gelezhe","sequence":"first","affiliation":[{"name":"Research and Practical Clinical Center for Diagnostics and Telemedicine Technologies of the Moscow Health Care Department , Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor","family":"Gombolevskiy","sequence":"additional","affiliation":[{"name":"Research and Practical Clinical Center for Diagnostics and Telemedicine Technologies of the Moscow Health Care Department , Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergey","family":"Morozov","sequence":"additional","affiliation":[{"name":"Research and Practical Clinical Center for Diagnostics and Telemedicine Technologies of the Moscow Health Care Department , Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitry V","family":"Melnikov","sequence":"additional","affiliation":[{"name":"Plastic Surgery Department, I.M.
