Slide 1-

Perforation of tympanic membrane Chunfu Dai Otolaryngology Department Eye Ear Nose & Throat Hospital Fudan University
Slide 2-

Pathogensis Direct force Careless while removal wax by himself or herself Skull fracture may tear TM Hot slag fly into the ear
Slide 3-

Pathogenesis Indirect force Increase in violence and firearms Associated with more dismal outcome More likely to involve intracranial lesions Barotrauma Rapid pressure fluctuations with the inner ear Air travel or SCUBA diving “the bends”
Slide 4-

Associated complications Is usually associated with TM or inner ear trauma unless Iatrogenic Ossicular discontinuity Facial Nerve Injury Chorda tympani Nerve Injury Barotrauma to Stapes footplate
Slide 5-

Clinic presentations Otalgia Bleeding Fullness Hearing loss: conductive HL or mixed HL Tinnitus Shape of perforation is split
Slide 6-

Physical examination Tympanic perforation Central perforation Marginal perforation Blood crust If skull base fracture is occurred with CSF leakage, clear fluid is observed.
Slide 7-

Diagnosis The key point is to exclude whether it associates with trauma to ossicular chain or to inner ear. The audiometry can provide useful informations. CHL > 40db suspicion for ossicular discontinuity Hearing test reveals sensorneurous HL, it means inner ear injury
Slide 8-

Managements 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.
