Abstract
Otitis media with effusion is defined by the presence of middle ear
effusion behind an intact tympanic membrane without signs or symptoms of
acute infection(1), the effusion may be serous, mucoid, purulent, or a
combination of these. (2)
It is one of the most frequent diseases of early infancy and
childhood and one of the most common reasons for children to visit a
physician.(3)
OME is the most common cause of acquired hearing loss in
childhood and has been associated with delayed language
development and behavioural problems.(4)
The most successful technique for ridding the middle ear of fluid,
restoring the health of the middle-ear mucosa, improving hearing loss, and
maintaining an air-filled middle-ear space is myringotomy and placement of
tympanostomy tubes (also called ventilation tubes or grommets). (96)
The aim of the work is to evaluate the effects of two different materials
of ventilation tubes on the outcome of the myringotomy as a surgical
treatment in otitis media with effusion
Fourteen patients between the ages of five and fifteen have been
proved clinically and audiologically to have bilateral chronic secretory otitis
media type (B) tympanometery.
All the selected patients were cadidates for myringotomy & tube
insertion.
