Scientific notes
Libelle of note
The promontorium gives rise to several bony ridges: (a) the ponticulus promontorii; (b) the subiculum promontorii; and (c) the finiculus.
In the retrotympanum, lateral and medial spaces relative to the facial nerve and pyramidal eminences were defined: lateral, the sinus facialis and the sinus tympanicus lateralis; medial, the sinus tympanicus posterior and the sinus tympanicus.
The paries mastoideus shows three bony eminences, each giving rise to a ridge: (a) the eminentia pyramidalis; (b) the eminentia chordae tympani; and (c) the eminentia styloidea.
See note # 7175
For the paries auris mediae, several new terms have been added giving credit to clinical findings (from Mansour S. Magnan J, Ahmad Hh, Nicolas K, Louryan S 2019 Comprehensive and Clinical Anatomy of the Middle Ear, 2nd ed. Springer, Cham).
New term; the Ponticulus promontorii is a thin bony bridge from the Eminentia pyramidalis to the Promontorium (from Lang J 1992 Klinische Anatomie des Ohres. Springer, Wien - New York).
The chorda tympani passes from the facial canal through the posterior tympanic canaliculus to enter the tympanic cavity via the apertura tympanica canaliculi chordae tympani posterioris; via the apertura tympanica canaliculi chordae tympani anterioris, the chorda tympani enters the anterior tympanic canaliculus (see also TA98, A02.1.06.011 canaliculus chordae tympani)
See note # 8208
The clinical term cog refers to a coronally oriented osseous ridge protruding in the middle ear cavity, for which the term processus inferior tegminis was introduced (Lang J 1992 Klinische Anatomie des Ohres. Springer, Wien – New York).
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).
