TEST 1 – EENT (OTALGIA AND NASAL SINUSES)

The most common cause of otitis externa is accumulation of water in the ear, leading to maceration and desquamation of the lining and conversion of the pH from acid to alkaline (e.g., swimming or frequent showers). It also may be initiated by trauma from scratching (fingernail or cotton-tipped applicator) or poorly-fitting earplugs for swimming. ................
