OTITIS EXTERNA
PATHOPHYSIOLOGY
Otitis externa is linked with infectious, inflammatory ear and head conditions.
Otitis externa typically affects the external auditory canal the part of the ear via which sound waves travel to reach the tympanic membrane.
Any obstruction in wax formation ,trauma to the canal or blockage can disrupt the external auditory canal’s protective mechanisms, and lead to pathogen overgrowth and inflammation.
The skin becomes erythematous, swollen, tender, and warm, leading to debris and discharge accumulation.
The narrowing of the canal, in combination with the accumulation of debris, leads to further entrapment of pathogens and propagating the infective process.
