A 27-yeаr-оld mаle presents tо yоur clinic with а history of head trauma from a motorcycle accident two weeks ago. He reports a feeling of fullness in his left ear and difficulty hearing out of that ear. Otoscopy is unremarkable with an intact and healthy-appearing tympanic membrane. There is no history of noise exposure, ear infections, or ototoxic medication use. Audiometric testing reveals: Pure-tone audiometry: Air conduction thresholds show a mild-to-moderate hearing loss in the left ear, with bone conduction thresholds within normal limits across all frequencies. An air-bone gap of 25–30 dB is present, especially in the mid to high frequencies (1000–4000 Hz). Tympanometry: A normal ear canal volume and a Type Ad tympanogram in the left ear. Questions: Based on the symptoms, history and test results, which condition is the most likely diagnosis for this patient? (2 points) How does this condition (your diagnosis) affect the mass or stiffness characteristics of the middle ear system, and how does that alteration influence sound transmission in terms of frequency and intensity?
