H74: Other disorders of middle ear and mastoid

The group of conditions known as Other disorders of the middle ear and mastoid typically involve abnormal alterations or complications within the middle ear or the mastoid process, a bone located behind the ear. Causes can range from infections to trauma to the ear or skull, and conditions can be congenital or acquired later in life. Typical symptoms may include pain, hearing loss, tinnitus (ringing in the ears), and possibly discharge from the ear. If an infection is involved, symptoms like fever, fatigue, and irritability might also be experienced. The progression and severity of these disorders largely depend on the underlying cause and early detection could prevent long-term complications. These disorders primarily affect the auditory system, sometimes leading to temporary or permanent hearing impairment.
