Within the medical field of otology, the Stenvers projection is a radiological technique that provides an oblique view of the skull and establishes a better perspective on the petrous bone, bony labyrinth, and internal auditory canal.{{cite book |last1=Mafee |first1=Mahmood F. |last2=Valvassori |first2=Galdino E. |title=Imaging of the Head and Neck |date=7 December 2004 |publisher=Thieme |isbn=9783131634825 |url=https://books.google.com/books?id=Ln1PJ3x0_7gC |access-date=26 March 2023}} It focuses on the posteroanterior and lateral planes.

For the Stenvers projection, a patient is placed facing the film, with the head flexed slightly and rotated 45 degrees away from the side being examined. The X-ray beam will be angled 10 to 15 degrees caudal.{{cite book |editor1-last=Lichtor |editor1-first=Terry |title=Clinical management and evolving novel therapeutic strategies for patients with brain tumors |date=April 2013 |isbn=9789535110583 |url=https://library2.um.edu.mo/ebooks/b28317944.pdf}}
