Aditus To Mastoid Antrum
The aditus to mastoid antrum (otomastoid foramen) is a large, irregular opening upon the posterior wall of the tympanic cavity by which the mastoid antrum (situated posteriorly) communicates with the epitympanic recess of the tympanic cavity (situated anteriorly). The walls of the antrum are lined by mucosa which is continuous with that lining the mastoid cells and tympanic cavity. The medial wall of the aditus features a ridge created by the underlying facial canal, and a bulge created by the underlying ampulla of the lateral semicircular canal. The short limb of incus is lodged in a shallow fossa upon the posterior wall of the tympanic cavity just inferior to the aditus. The pyramidal eminence The pyramidal eminence is a hollow conical projection upon the posterior wall of the tympanic cavity of the middle ear. The stapedius muscle arises in the hollow of the eminence and its tendon exits through its apex. The pyramidal eminence is si ... is situated inferior to the aditus. S ...

Laryngeal Aditus
The laryngeal inlet (laryngeal aditus, laryngeal aperture) is the opening that connects the pharynx and the larynx. Borders Its borders are formed by: * the free curved edge of the epiglottis, anteriorly * the arytenoid cartilages, the corniculate cartilages, and the interarytenoid fold, posteriorly * the aryepiglottic fold The aryepiglottic folds are triangular folds of mucous membrane of the larynx. They enclose ligamentous and muscular fibres. They extend from the lateral borders of the epiglottis to the arytenoid cartilages, hence the name 'aryepiglottic'.
