ASOM
It is an acute inflammation of middle ear cleft by pyogenic organisms.
Age-Infants and children of lower socio-economic group as Eustachian tube in infants and young children is shorter, wider and more horizontal and thus may account for higher incidence of infections in this age group.
Routes-
Eustachian tube (Commonest) -Infection i .e. URTI ,horizontal breast feeding ,swimming through nasopharynx into middle ear(So keep infant propped up during breast feeding)
External ear-When TM perforation Blood borne
Predisposing factors-
Recurrent attacks of common cold, upper respiratory tract infections, and exanthematous fevers like measles, diphtheria, whooping cough
Infections of tonsils and adenoids Chronic rhinitis and sinusitis Nasal allergy
Tumours of nasopharynx, packing of nose or nasopharynx for epistaxis Cleft palate
Organism- S.pneumoniae(30%) H.influenzae(20%) Moraxella catarrhalis(12%)
Others-S.pyogen ,S.aureus ,P.aeruginosa
Stages-
Stage of tubal occlusion-Deafness ,earache ,retracted TM ,conductive deafness
Stage of pre-suppuration-Marked deafness and earache ,congested TM , cart-wheel TM
,conductive deafness
Stage of suppuration-Pus formation ,excruciating earache , high fever ,vomiting ,bulging of TM ,lost landmarks ,yellow spot on TM ,X ray mastoid shows cloudy appearance
Stage of resolution-Rupture TM with evacuation of pus ,relieved earache
Stage of complication-Acute mastoiditis, subperiosteal abscess, facial paralysis, labyrinth itis, petrositis, extradural abscess, meningitis, brain abcess or lateral sinus thrombophlebitis.

Cholesteatoma
It is the presence of keratinised of epithelium in the middle ear or mastoid
skin in the wrong place It is a misnomer
Cholesteatoma consists of -
1.Matrix, which is made up of keratinising squamous epithelium resting on a thin stroma of fibrous tissues
2.A central white mass, consisting of keratin debris produced by the matrix .For this reason, it has also been named epidermosis or keratoma
Origin of chlesteatoma/Genesis/Theory
1.Presence of congenital cell 2.Invagination of pars flaccida 3.Basal cell hyperplasia 4.Epithelial invasion 5.Metaplasia
Types-
Congenital-Presence of embryonic epidermal cell , occurs at middle ear ,petrous apex
,cerebellopontine angle
Acquired primary-Invagination of pars flaccida ,basal cell hyperplasia ,metaplasia
Acquired secondary-Migration of keratinised cell through perforation of TM ,metaplasia of middle ear lining
Eroding of bone by cholesteatoma-
Chemical theory ,ischaemic pressure theory
Enzymatic theory-Collagenase , phosphatase and proteases
Structures injured by cholesteatoma-
Ossicles
Bony labyrinth Canal of facial nerve Tegmen tympani
Investigation-
Town's view x ray mastoid-Sclerotic mastoid Ear swab-C/S
Ct scan
Hearing assessment Pure tone audiometry
Rx-
Medical Rx is of no use ,as it may be life threatening

Why cholesteatoma is dangerous?-(Why attico antral CSOM is dangerous)
Due to eroding power
Produce both intracranial and extracranial complications
