An endoscopic transcanal approach has been recently proposed to treat the different lesions in this area. The aim of the study is to describe the anatomical pathway of this approach by measuring the dimensions of its boundaries while checking their correlation with the pneumatization of the SGF area. Methods: This is a retrospective anatomical analysis of Cone Beam CT scans of 80 patients, for a total of 160 temporal bones analyzed. Two checkpoints were measured for the SGF route, as an internal and an external window. These are triangles between the MCF dura, the geniculate ganglion and the ASCC on parasagittal and axial planes. The pneumatization of the SGF was also assessed, classified and correlated with the measured dimensions. Results: The depth of the SGF was 7.5 \u00b1 1.8 mm. The width of the external window was 7.5 \u00b1 1.9, 5.6 \u00b1 2.4 and 1.6 \u00b1 1.6 mm for the posterior, middle and anterior points of measurement, respectively. The height of the internal window was 7.6 \u00b1 1.2, 4.5 \u00b1 1.5 and 1.7 \u00b1 1.7 mm for the posterior, middle and anterior points of measurement, respectively. Type A pneumatization was found in 87 cases, type B in 34 and type C in 39. The degree of pneumatization directly correlated to the depth and height of the fossa. Conclusions: The suprageniculate approach route is defined by the internal and external windows which should be evaluated during a pre-surgery imaging assessment. The detailed anatomy of the approach and the novel classification of the pneumatization of the SGF are here described which may be useful to plan a safer procedure with minimal complications.<\/jats:p>","DOI":"10.3390\/jpm14050516","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T08:03:08Z","timestamp":1715673788000},"page":"516","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Detailed Radiomorphometric Analysis of the Surgical Corridor for the Suprageniculate Approach"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3639-4422","authenticated-orcid":false,"given":"Tomasz","family":"Wojciechowski","sequence":"first","affiliation":[{"name":"Department of Descriptive and Clinical Anatomy, The Medical University of Warsaw, 5 Chalubinskiego St., 02004 Warsaw, Poland"},{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, The Medical University of Warsaw, 1a Banacha St., 02097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9029-8530","authenticated-orcid":false,"given":"Nicola","family":"Bisi","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, Azienda Ospedaliero-Universitaria di Modena, Via del Pozzo 71, 41125 Modena, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazimierz","family":"Szopi\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Dental and Maxillofacial Radiology, The Medical University of Warsaw, 6 Bienieckiego St., 02097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele","family":"Marchioni","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, Azienda Ospedaliero-Universitaria di Modena, Via del Pozzo 71, 41125 Modena, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"850","DOI":"10.1177\/0194599816661482","article-title":"Geniculate Ganglion Tumors: Clinical Presentation and Surgical Results","volume":"155","author":"Lahlou","year":"2016","journal-title":"Otolaryngol.
