The Effect of Chronic Middle Ear Inflammation on the Develop- Ment of the Mastoid Air Cell System

The effect of chronic middle ear inflammation on the development of mastoid air cell system was investigated in piglings, whose tympanic bullae closely resemble the human mastoid air cell system. Experimental chronic otitis media was produced by the injection of glycerin into the middle ear cleft of piglings aged from 5 days to 5 weeks after birth. The piglings were subsequently decapitated and...
