Middle Ear Acute Otitis Media Viral respiratory infections cause inflammation of ET When ET is blocked, fluid collects in the middle ear.
Middle Ear Acute Otitis Media Common in fall, winter or spring ET in child is shorter and more horizontal in infants/children. Bacterial Etiology : S.pneumoniae, H.influenzae, and M.Catarrhalis. Risks include URI,smoking at home, allergies, cleft palate, adenoid hypertrophy, bottle feeding, barotrauma
Middle Ear Acute Otitis Media Otalgia. Conductive hearing loss URI symptoms Vomiting, diarrhea Fever TM bulging and erythematous with decreased or poor light reflex. Decreased TM mobility on pneumatic insufflation

Middle Ear Acute Otitis Media -Complications TM perforation/ Tympanosclerosis Recurrent AOM or chronic OM Persistent middle ear effusion Mastoiditis Bacteremia
Middle Ear Acute Otitis Media -Recurrent OM Three episodes of AOM in 6 months or 4 episodes in 12 months Diagnosis Prevent by antibiotic prophylaxis, pneumovax, tympanostomy tubes, adenoidectomy
Middle Ear Otitis Media with Effusion Fluid accumulation behind TM in middle ear Build up of negative pressure and fluid in eustachian tube Common in children because of anatomy, cleft palate, allergies, barotrauma.
Middle Ear Otitis Media with Effusion Hearing loss Fullness, pressure TM neutral or retracted. Gray or pink. Landmarks visible or dull. Decreased TM mobility
Middle Ear Otitis Media with Effusion Diagnosis Tympanometry- most accurate, Audiometry- Differentials to include: Acute Otitis Media, malignant tumors to nasal cavity, cystic fibrosis

Barotrauma Physical damage to body tissue due to difference in pressure between an air space inside or beside body and surrounding gas. Ear barotrauma:
Barotrauma Etiology is a change in atmospheric pressure. Negative pressure in the middle ear causes Eustachian tube to collapse. Since air can not pass back through the ET, hearing loss and discomfort develop Risk factors Differential diagnosis should include serous, acute or chronic otitis media, bullous myringitis
Barotrauma Hearing loss Otalgia

Mastoid Portion of temporal bone posterior to the ear. Mastoid air cells connect with the middle ear Fluid in the middle ear can lead to fluid in the mastoid
Mastoiditis Middle ear inflammation spreads to mastoid air cells resulting in infection and destruction of the mastoid bone. Etiology: Streptococcus pneumoniae, Haemophilus influenzae, streptococcus pyogenes, and other bacteria
Mastoiditis Pain Bulging erythematous TM Erythema, tenderness, edema over mastoid area Postauricular fluctuance
Mastoiditis- Diagnosis/differentials Diagnosis: CT show bony destruction or drainable mastoid abscess Tympanocentesis to culture middle ear fluid.( S. pneumoniae, H. influenzae, M. catarrhalis)\ Culture of fluid Differential diagnosis to include otitis media, Cellulitis, scalp infection with inflammation of posterior auricular nodes
