The Passport comes with a 4.5-inch square touch display with a 1440 x 1440 resolution and 453 PPI pixel density. Thanks to the integration of a touch-sensitive panel inside the hardware QWERTY keyboard below the display, your fingers almost never get in the way of reading or otherwise interacting with on-screen content.
Injury to the outer ear is by far the most common cause of tenderness and pain. The injury is usually obvious like with an ear piercing or blow to the ear. Trauma leads to inflammation which is characterized by pain, redness and swelling.
With patulous Eustachian tube, variations in upper airway pressure associated with respiration are transmitted to the middle ear through the Eustachian tube. This causes an unpleasant fullness feeling in the middle ear and alters the auditory perception. Complaints seem to include muffled hearing and autophony. In addition, patulous Eustachian tube generally feels dry with no clogged feeling or sinus pressure.
