E.N.T-CSOM
CHRONIC SUPPURATIVE OTITIS MEDIA
It is a long standing infection of a part or
whole of the middle ear cleft charactrised
by ear discharge and a perforation.
Epidemiology
Incidence of CSOM is higher in developing
countries because of low socio-economic
standards,poor nutrition and lack of
health education.
It affects both sexes and all age groups.
Types of CSOM
It is divided into two types
1)Tybotympanic
2)Atticoantral
1)Tybotympanic
It is also called safe or benign type and
it involves anterioinferior part of middle
ear cleft and is associated with a central
perforation.
Aetiology
It is common in childhood
It is the sequela of acute otitis media
usuallyfollowing exanthematous fever
Ascending infection via the eustachian tube.
Pathology
1)Perforation of pars tensa
2)Edematous of middle ear mucosa
3)Polyp in external canal
4)Some degree of nicrosis in ossicular chain
5)Tympanosclerosis
6)Fibrosis and adhesions
Bacteriology
Common aerobic organims-
1)PS aeruginosa
2)Proteus
3)Esch. coli
4)staph. aureus
common anaerobes are
1)Bacteroides fragilis
2)anaerobic sreptococci
Clinical Features
1)Ear discharge
2)Hearing loss
3)Perforation of tympanic membrane
4)Oedematous and swollen of middle ear
Investigation
1)Examination under microscope
2)Audiogram
3)Culture and sensitivityof ear discharge
4)Mastiod x-rays
Treatment
1)aural tiolet
2)ear drops containing neomycin,
polymyxin,chloromycetin.
3)systemic antibiotics
4)precausions
5)treatment of contributory causes
6)surgical treatment
7)reconstrutive surgery
