USEFULNESS OF BISMUTH IODOFGRM PARAFFIN PASTE FOR MASTOID PACKING AFTER OPEN-METHOD TYMPANOPLASTY

Abstract

Bismuth iodoform paraffin paste (BIPP) is a time-honoured antiseptic dressing widely used in England, however, its use is rarely reported in Japan.
In order to evaluate the effectiveness of BIPP as mastoid packing materials, mastoid cavities of 31 ears were packed with gauzes impregnated with BIPP and bacteriological study was undertaken before and after surgery.
None of the cases showed an obvious infection one week after the operation when the packing was removed, and bacteriological examinations revealed sterile or decreased bacteria in the packed cavity.
BIPP seemed to be most uneful as a packing material in an ear after open-method tympanoplasty.
This material has also been used in treating ears with cavity problems, and has shown to have effects to reduce otorrhea.
