Overview
Physical Examination
HEENT and Neck
- The following physical exam findings in the ear canal are indicative of otitis externa:[1]
- Erythema and edema.
- Tenderness of the tragus and auricle.
- Cellulitis of the auricle and ear canal.
- Otorrhea
- Granulation tissue
- Stenosis of the ear canal.
- Buildup of mycotic debris.[2]
- Lack of cerumen.
- In the neck, lymphadenitis may be present in acute otitis externa.[3]
- In malignant necrotizing otitis externa, the patient may present signs of trismus and partial facial palsy.[4]
Appearance of the Patient
- For acute otitis externa, the patient can appear ill if the cause is infectious and is accompanied by fever.[5]
- Patients with chronic otitis externa are usually well-appearing.
- Malignant necrotizing otitis externa patients are usually ill-appearing due to the accompanying fever and facial palsies.[4]
