[2] [3] The most common cause of otitis externa is bacterial. Risk factors for acute cases include swimming, minor trauma from cleaning, using hearing aids and ear plugs, and other skin problems, such as psoriasis and dermatitis. [2] [3] People with diabetes are at risk of a severe form of malignant otitis externa. [2]
One red flag is the presence of one or multiple risk factors including smoking, heavy alcohol use (greater than 3.5 drinks per day), diabetes, coronary artery disease, and older age (greater than 50). [3] These factors increase the risk of having a serious cause of ear pain, like cancer or a serious infection.
A third form, malignant otitis externa, or necrotising otitis externa, is a potentially life-threatening, invasive infection of the external auditory canal and skull. [7] Usually associated with Pseudomonas aeruginosa infection, this form typically occurs in older people with diabetes mellitus, or immunocompromised people. [7]
The risk of contracting P. aeruginosa can be reduced by avoiding pools, hot tubs, and other bodies of standing water; regularly disinfecting and/or replacing equipment that regularly encounters moisture (such as contact lens equipment and solutions); and washing one's hands often (which is protective against many other pathogens as well).
Clinically, patients experience aural fullness, intra-meatal itching, and malodorous otorrhea all at the same time. Although granular myringitis does not typically result in a hearing loss, it can cause complications like inflammatory infiltration of the deep canal, canal atresia or stenosis, and post-inflammatory medial canal fibrosis.
Otomycosis does not usually cause as much canal skin edema as does acute bacterial external otitis.While a severe pressure type of pain is a prominent feature of advanced cases, the ear is usually much less tender, if at all, to traction or tragal pressure.

The aetiology for tympanosclerosis is not extensively understood. There are several probable factors which could result in the condition appearing, including: Long term otitis media (or 'glue ear') [2] Insertion of a tympanostomy tube. [4] [5] [6] If aspiration is performed as part of the insertion, the risk of tympanosclerosis occurring ...
