Performing skull base reconstruction also demands a layer-by-layer understanding of the SCALP and fasciae. We aimed to examine the relationship between the SCALP layers, temporal fascia (TF) and facial nerve branches from a surgical viewpoint and highlight the optimal dissection plane during the COZA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>The SCALP and temporal fascia layers were examined using COZA on 10 formalin-fixed cadavers (20 sides).

Facial nerve branches coursed between the galea and the TF. The TF divided into superficial and deep layers; superficial layer continuous with the pericranium and extending anteriorly toward periorbita. Following the superficial layer of the TF inferiorly provided a natural interfascial surgical plane for exposure of the ME. Deep layer of the TF further divided into medial and lateral laminae with an interfascial fat pad between them. The lateral and medial laminae attached to the lateral and medial surfaces of the zygomatic arch, respectively, and merged at the superior margin.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclus\u0131ons<\/jats:title>\n                    <jats:p>Recognizing the interfascial plane between the superficial and deep layers of the TF and the deep interfascial fat pad, may improve surgical orientation and facilitate tissue retraction during exposure of the lateral orbital wall and ME in the COZA.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00701-026-06947-8","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T13:24:28Z","timestamp":1781097868000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["SCALP and temporal fascia in the cranio-orbito-zygomatic approach: highlighting the interfascial dissection plane"],"prefix":"10.1007","volume":"168","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1529-6476","authenticated-orcid":false,"given":"Tufan Agah","family":"Kartum","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayberk","family":"Karaman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Levent","family":"Ayd\u0131n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eren","family":"So\u011fuk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Revna","family":"\u00c7etiner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tuba \u00d6zge","family":"Kara\u00e7oban","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kardelen","family":"Ak\u0131nc\u0131","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7628-9443","authenticated-orcid":false,"given":"Necmettin","family":"Tanriover","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"6947_CR1","unstructured":"(2016) Head and neck.
