Study Notes
Official Websites
- Federal websites typically end in .gov or .mil, indicating they are official sources.
- Checking for "https://" ensures a secure connection and encrypted information transmission.
Otitis Externa
- Defined as inflammation of the external auditory canal, characterized by erythema and edema.
- Period prevalence is 1.3% in females and 1.2% in males over a 12-month period.
- Common symptoms include otalgia (ear pain) and infected discharge; hearing remains unchanged unless the canal is obstructed.
- Pain increases with tragus movement; otoscopy reveals a narrowed, inflamed canal with infected squamous debris.
Treatment Guidelines
- Initial treatment focuses on topical medications; patients should avoid inserting objects into ears or getting them wet.
- For potential splashing, use cotton wool coated with Vaseline® as an ear plug.
- Topical preparations with an antimicrobial and steroid are effective; no significant differences between types unless fungal infection is suspected.
- For suspected fungal infections, use Locorten-Vioform® and perform a swab for culture and sensitivity.
Indications for Referral and Further Treatment
- No systemic antibiotics required if there's no systemic infection or severe underlying disease.
- If symptoms persist, consider ENT referral for aural microsuction.
- Severe pain may necessitate hospitalization.
Potential Complications
- External ear infections can lead to cellulitis or perichondritis, and may extend to the skull base, causing necrotizing otitis externa.
- Urgent systemic antibiotics and ENT referral needed for complications, especially with cranial nerve palsy, granulations in the canal, or swelling of the pinna.
Otitis Media
- Most common in children, with a 11.5% incidence in the first year of life.
- Does not cause otorrhea unless the tympanic membrane is perforated.
- Symptoms include reduced hearing, pain relief followed by otorrhea, and examination reveals signs of tympanic membrane perforation and mucopurulent discharge.
- Typically resolves within 24 hours; systemic antibiotics have limited benefit except for bilateral cases in young children.
