Definition and Terminology

Otitis media represents an inflammatory condition of the middle ear and mastoid space.

The presence or absence of middle-ear effusion (MEE) and its duration help further to define the process.

Effusion is the liquid resulting from infection and mucosal inflammation ,can be serous (thin, watery), mucoid (thick, viscous), or purulent (pus).

Definition and Terminology

Otitis media with effusion (OME) can occur as a post inflammatory response to Acute Otitis Media (AOM) from a viral infection, or because of Eustachian-tube dysfunction.

Chronic suppurative otitis media (CSOM) is characterized by persistence of purulent otorrhea through a tympanic membrane (TM) perforation or tympanostomy tube (TT) that is unresponsive to medical therapy

Duration

• 0 to 3 weeks in durationACUTE

• 3 to 12 weeks in duration

SUBACUTE

• longer than 12 weeks in duration

CHRONIC

Epidemiology

The onset of AOM during the first year of life is important because the majority of children with multiple recurrences of AOM have their first episode before the age of 12 month

Associated with upper respiratory infections (URIs). Prevalence is similar between boys and girls. Children who live in crowded households or low

socioeconomic conditions or who have poor medical care or both also have been found to have an increased incidence in both acute and chronic OM

Etiology

AOM is a complication of eustachian tube dysfunction that occurred during an acute viral upper respiratory tract infection Streptococcus pneumoniae (most often) Haemophillus influenzae Branhamella catarrhalis Streptococcus β-hemoliticus group A Staphyllococcus aureus E. Coli RSV

Risk Factor Age (younger), ET in infants and children is shorter, more

horizontal, and functionally less mature compared with that in adults.

Allergies Nasal obstruction (sinusitis, adenoid hypertrophy, nasal or

nasopharyngeal tumors) Craniofacial abnormalities (ex. Cleft palate, deformity of the

midface, skull base, nose/ paranasal sinus, Down syndr, etc) Exposure to enviromental smoke or irritants Exposure to group day care Family history of recurrent acute otitis media Immunodeficiency No breastfeeding Upper respiratory tract Infection

Staging

Occlusion

• Retraction of tympanic membrane because of negative pressure in middle ear, created by air absorbtion.

• Chief complaint : tinnitus, sensation of fullness• PE : normal tympanic membrane or in livid color. Maybe

the effusion has been occured, but can’t be recognized. This stage is hard to be distinguish with serous otitis media which caused by virus or allergic reaction.

Hyperemic

• Vascular dilatation in tympanic membrane so the tympanic membrane in reddish/hyperemic looks or oedema. Secretes may hard to be noticed.

• Chief Complaint : painful perception • PE: tympanic membrane is reddish, edema

Suppurative

• The mucous in middle ear in edema state and the epithelium destroyed, so the middle ear now filled by purulent exudate. This can cause tympanic membrane bulging to the outside.

• Chief Complaint : Pain at ear, heart rate, temperature of the body raise. PE: Tympanic membrane is bulging. If the pressure in the middle ear can’t be reduced, can caused iscemic condition of the tympanic membrane because of pressure to the capillaries. Necrotic at tympanic membrane cause the tympanic membrane looked as flabby and yellowish color. This is the site where rupture could take place.

Perforated

• Late in giving antibiotics therapy, tympanic membrane will be rupture and pus drains out from the middle ear.

• Chief Complaint : Child will be calm now, reduce in body temperature, and sleep well.

• PE: Tympatic membrane is rupture and pus drains out

Resolution

• If the tympanic membrane still intact, the condition of tympanic membrane slowly back to normal. If there is a perforation, secretes will reduced and dried. Resolution will takes place without medication if the immune system still in good performance

Clinical Findings

Child Upper tract infection Pain inner ear Fever Restless Fullness in the ear Hearing loss

Adults pain fullness in the ear hearing loss occured

Management Occlusion

Decongestan (Child < 12y.o: HCl ephedrine 0.5% in physiologic solution, Child>12 th: HCl efedrine1% in physiologic solution)

Antibiotics

Hyperemic Antibiotic: amoxicillin 40 mg/kgBB/day in 3 doses, ampicillin

50-100 mg/kgBB/day in 4 doses, eritromicin 40 mg/kgBB/day.

Decongestan Analgetics Antipiretics

Management

Suppurative Antibiotics: amoxicillin 40 mg/kgBB/day in 3 doses,

ampicillin 50-100 mg/kgBB/day in 4 doses, eritromicin 40 mg/kgBB/day.

Myringotomy Analgetics Antipiretics

Perforated H2O2 3% 5 drops 3 dd 1 3-5 days Antibiotic local (ear drops)

Management

Resolution If the resolution didn’t take place, secretes will drained

out by the perforation in tympanic membrane. The antibiotics continued for 3 weeks. If 3 weeks pasts and secretes stills, mastoiditis should be in differential diagnosis
