A retrospective view of 37 Per-Lee tubes inserted into 29 patients over a period of four years. At the time of review all the tubes were in situ but eleven had to be removed due to recurrent otorrhoea or perforations causing increasing deafness particularly in children. Per-Lee tubes are not suitable for long-term ventilation of the middle ear cavity in children.
