Notes
The promontorium shows a bony overhang over the cochlear or round window, comprising a postis anterior (anterior pillar), a roof (tegmen) and a postis posterior (posterior pillar) as described by Bolobas B (1972 A hallószery mikrochirurgial anatomija. Könykiadó, Budapest (in Hungarian); Proctor B, Bolobas B, Niparko JK 1986 Anatomy of the round window niche. Acta Otol Rhinol Laryngol 95:444-446). For the tegmen, the term canonus fossulae fenestrae cochleae has been suggested as it forms a canopy overhanging the cochlear window (Topsakal V, Matulic M, Assadi MZ, Mertens G, Van Rompaey V, Van de Heyning P 2020 Comparison of the surgical techniques and robotic techniques for cochlear implantation in terms of the trajectories toward the inner ear. J Int Adv Otol 16:3-7).
