Abstract

The fate of 32 Per-Lee ventilation tubes inserted by a single surgeon for secretory otitis media in children and adults is analysed over a 15-year period. There were no extrusions and 25 tubes were still functional at the time of the survey. The total ventilation time achieved by the 32 tubes was over 157 years. Seven tubes were removed on account of either obstruction or infection. Spontaneous healing of the tympanic membrane was uncertain following removal of the tube and a considerable degree of scarring was inevitable. Hearing improvement occurred while the tube was functioning and there were no cases of hearing deterioration. It is concluded that the Per-Lee tube is a suitable prosthesis for long-term middle-ear ventilation.
