No perfusion was observed after elevation of the buccal-mandibular area SMAS. In contrast, a prominent axial vessel was visible within the superficial temporal fascia. When this fascia was dissected, it was predominantly perfused by the parietal branch of the superficial temporal artery, which was present bilaterally in all patients. The superficial temporal fascia showed a marked peak in blood perfusion after dissection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Perfusion of the buccal-mandibular area SMAS originated from a transverse facial artery perforator in the deep layer and remained poor during extended SMAS rhytidectomy. Because of the poor perfusion of the buccal-mandibular area SMAS after elevation, high-risk patients may benefit from composite facelifts, less extensive skin dissection, or preservation of the transverse facial artery perforator. The superficial temporal fascia can be harvested as an inferior-pedicled flap down to the zygomatic arch, whereas the buccal-mandibular area SMAS cannot be reliably harvested in this manner.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence: 4 (Therapeutic)<\/jats:title>\n                    <jats:p>For image description, please refer to the figure legend and surrounding text.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/asj\/sjag021","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T10:18:10Z","timestamp":1769422690000},"page":"623-629","source":"Crossref","is-referenced-by-count":0,"title":["Perfusion of the Superficial Musculoaponeurotic System and the Superficial Temporal Fascia During Facelift, as Assessed by Indocyanine Green Angiography"],"prefix":"10.1093","volume":"46","author":[{"given":"Chenzhi","family":"Lai","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinhang","family":"Dong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fangning","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoshuang","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2894-4700","authenticated-orcid":false,"given":"Xiaolei","family":"Jin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"2026051813465819700_sjag021-B1","doi-asserted-by":"publisher","first-page":"80","DOI":"10.1097\/00006534-197607000-00013","article-title":"The superficial musculo-aponeurotic system (SMAS) in the parotid and cheek area","volume":"58","author":"Mitz","year":"1976","journal-title":"Plast Reconstr Surg"},{"key":"2026051813465819700_sjag021-B2","doi-asserted-by":"publisher","first-page":"481","DOI":"10.1067\/maj.2002.128628","article-title":"The \u201cHigh SMAS\u201d face lift technique","volume":"22","author":"Barton","year":"2002","journal-title":"Aesthet Surg J"},{"key":"2026051813465819700_sjag021-B3","doi-asserted-by":"publisher","first-page":"1011","DOI":"10.1097\/00006534-199709001-00027","article-title":"The contribution of the SMAS to the blood supply in the lateral face lift flap","volume":"100","author":"Whetzel","year":"1997","journal-title":"Plast Reconstr Surg"},{"key":"2026051813465819700_sjag021-B4","doi-asserted-by":"publisher","first-page":"480","DOI":"10.1097\/00006534-199708000-00033","article-title":"The arterial supply of the face lift flap","volume":"100","author":"Whetzel","year":"1997","journal-title":"Plast Reconstr Surg"},{"key":"2026051813465819700_sjag021-B5","doi-asserted-by":"publisher","first-page":"683","DOI":"10.1097\/00006534-199504000-00009","article-title":"A comparison of flap vascular anatomy in three rhytidectomy techniques","volume":"95","author":"Schuster","year":"1995","journal-title":"Plast Reconstr Surg"},{"key":"2026051813465819700_sjag021-B6","doi-asserted-by":"publisher","first-page":"2287","DOI":"10.1097\/00006534-200006000-00001","article-title":"The angiosomes of the head and neck: anatomic study and clinical applications","volume":"105","author":"Houseman","year":"2000","journal-title":"Plast Reconstr Surg"},{"key":"2026051813465819700_sjag021-B7","doi-asserted-by":"publisher","first-page":"1466","DOI":"10.1097\/SCS.0000000000005471","article-title":"Modification of rhytidectomy: stepped lift of the superficial musculoaponeurotic system","volume":"30","author":"Zhou","year":"2019","journal-title":"J Craniofac Surg"},{"key":"2026051813465819700_sjag021-B8","doi-asserted-by":"publisher","first-page":"52","DOI":"10.1016\/j.bjps.2021.08.002","article-title":"Leaving the perfusion zones?
