External auditory canal stenting utilizing a useful rolled, tapered silastic sheet (RTSS) post middle ear surgery.

OBJECTIVE

To overcome the demerits of conventional postoperative aural packing, we developed a useful protocol for postoperative stenting of the external auditory canal after middle ear surgery which enables transcanal drainage and simultaneously allows for visual inspection and treatment of the canal, as necessary.

METHODS

Twenty-four surgeries, 21 patients underwent tympanoplasty with a postaural incision. At the end of all surgical procedures, the external auditory canal was packed with a 0.3mm thickness rolled, tapered silastic sheet (RTSS) with antibiotic ointment applied to one surface. The inserted RTSSs were removed at 5-10 days postoperatively. We assessed the efficacy and the reliability of the RTSS.

RESULTS

In 23 ear surgeries on 20 patients, we achieved successful postoperative ear packing utilizing our RTSS. With these patients, the tympanic membrane and the external auditory meatus were able to be observed immediately after the completion of the stenting during the surgery and the removal of the gauze over the operated ear at Day 1 to Day 3 postoperatively. During 4 surgeries with ventilation tube insertion to the tympanic membrane, there was secretion through the inserted ventilation tube which was easy to suction. In one surgery, on one patient, additional packing materials were utilized once only during a sandwich graft myringoplasty. No patients showed any harmful effects during the postoperative period.

CONCLUSIONS

The useful and reliable RTSS, with antibiotic ointment applied to one surface, has several positive advantages that the conventional packing methods do not.
