Yukiko Iino is an emeritus and visiting professor of Jichi Medical University, and now working as a chief staff of the Dept. of Otolaryngology/Deafness and Middle Ear Surgicenter. Her work has focused on clinical and basic research on middle ear diseases. She published many articles including eosinophilic otitis media such as diagnostic criteria. She is also an ear surgery specialist and has operated on more than 7000 cases. Her interest is also in pediatric ORL. She served as the chairperson of the Japan Society for Pediatric ORL from 2015 to 2017. She contributed to creating and publishing the three Japanese guidelines for acute otitis media, otitis media with effusion, and ANCA-associated otitis media. In 2021, she was awarded the “Shining ENT female doctors’ award” of the Japan Society of ORL-HNS. Her favorite things are singing jazz standards and cooking.

The attic, or epitympanum, is a crucial space located in the upper part of the middle ear, housing the heads of the malleus and the body of the incus. Because it is a largely closed-off space, its aeration depends heavily on specific, narrow pathways controlled by mucosal folds.
Attic mucosal folds form a specialized passage way for air, allowing the Eustachian tube to ventilate the mastoid and attic spaces. Blockages in these folds can lead to negative pressure and retraction pockets.
Air generally travels into the middle ear via the Eustachian tube, filling the lower cavity. For this air to reach the upper attic and mastoid air cells, it must pass through specific gaps. If these ventilation pathways—especially the anterior isthmus—become blocked by inflammation, adhesions, or thick exudate, a condition known as Selective Dysventilation Syndrome can occur.
This section will cover the attic mucosal folds, the ventilation pathways formed by these folds, and the clinical significance of these structures.
