1. Bullous Myringitis Viral infection Confined to tympanic membrane
Primarily involves younger children

2. Symptoms Bullous Myringitis Sudden onset of severe pain No fever
No hearing impairment
Bloody otorrhea (significant) if rupture

3. Signs Bullous Myringitis Inflammation limited to TM & nearby canal
Multiple reddened, Hemorrhagic blebs

4. Treatment Bullous Myringitis Self-limiting Analgesics
Topical antibiotics to prevent secondary infection
Incision of blebs is unnecessary

5. Pseudocyst of the auricle
First reported by Hartmann in 1846
Fluctuant, tense, noninflammatory swelling of the upper ear
Believed to be associated with trauma

6. Treatment Pseudocyst of the auricle Medical Care Surgical Care
No medical treatment is uniformly effective.
Surgical Care
surgical incision and pressure dressing
aspiration followed by a pressure dressing
intralesional steroids
Surgical curettage and fibrin sealant

7. Injury of tympanic membrane
Earache
Bleeding
Fullness
Hearing loss:
conductive HL or mixed HL
Tinnitus
Shape of perforation is split

8. Treatment Injury of tympanic membrane Antibiotic to prevent infection
Aseptic external auditory canal with alcohol
Prevent super respiratory infection
Prohibit nasal blow
Prohibit ear drops
It takes 3-4 w to heal the ear drum
If 3 months later, perforation still exists, myringoplasty is indicated
