Perforation rates after ventilation tube insertion: does the positioning of the tube matter?

A prospective study was performed of children undergoing bilateral ventilation tube insertion. One hundred and twenty-one children aged between 9 months and 10 years 3 months were admitted for surgery for secretory otitis media (glue ear). Each child had a ventilation tube inserted anteriorly in the tympanic membrane of one ear and posteriorly in the tympanic membrane of the other. They underwent regular clinical and audiological assessment until extrusion of the ventilation tubes occurred. Perforations were noted in 2.75% of tympanic membranes (4.6% of the children). The rate with posteriorly placed ventilation tubes was higher than with the anteriorly placed ventilation tubes (3.7% compared with 1.8%) though this is not statistically significant.
