SHAH PERMAVENT
The
bevelled flange is intended to be cut to the shape best suited to
the clinical characteristics presented. The absence of an outer
flange aids retention and clinical studies show that this is a long
term tube which, if deliberately removed, is unlikely to leave a
perforation in the tympanum. This tube will ventilate the middle
ear for two full years, when they should be removed to prevent a residual perforation.
