The morphology of the suprameatal triangle and Henle's spine is of immense clinical significance to the otologic surgeons for approaching the mastoid antrum and for cochlear implantation procedures. A Study of 411 temporal bones (195 left and 216 right) revealed the presence of Henle's spine in 81.8% of Cases, with the crest type being the highest (66.7%). The different types of suprameatal triangles were deep (38.2%), shallow (42.6%), and slit (12.4%) variety. In 6.8% of the bones, the spine was absent. The occurrence of various types of suprameatal depression and spine along with their clinical significance are discussed.
