Overview
Risk factors for acute otitis externa include activities and conditions that predispose an individual to ear canal inflammation. They also include being a female between 65 and 74 years old. Risk factors for malignant necrotizing otitis externa include conditions predisposing an individual to immunocompromise, including undergoing chemotherapy or suffering from diabetes mellitus.
Risk Factors
- Risk factors for acute otitis externa include activities and conditions that predispose an individual to ear canal inflammation:[1]
- Scuba-diving, increasing the risk of trapped water in the ear canal.[2]
- Swimming in public pools or other unclean bodies of water, heightening the chance of bacterial or fungal infection.
- Living in a humid or tropical climate.[3]
- Developing dermatoses such as eczema, seborrhea, and psoriasis.[4]
- Loss of cerumen in the ear canal, lowering the amount of ear canal protective coating.
- Experiencing foreign objects that can cause irritation and inflammation, such as hearing aids or ear plugs.
- Having ear canal obstructions, such as sebaceous cysts.
- Experiencing suppuration from other ear diseases such as otitis media
- Undergoing prolonged treatment with topical antibiotics.[4]
- Raises risk of otomycosis.
- Experiencing physical trauma in the ear canal.
- Repeating exposure to irritants, such as soaps, shampoos, or related cosmetic chemicals.
- Having a narrow ear canal more prone to retaining water.
- Being a female between age 65 and 74.[5]
- For malignant necrotizing otitis externa, contributors to immunocompromise, including the following:[6]
