CONTINUOUS DRAINAGE TUBE IN TYMPANOPLASTY WITH MASTOID OBLITERATION

Abstract

Tympanoplasty with mastoid obliteration is sometimes performed on patients with cholesteatoma or sequelae after radical middleear surgery (i. e., open cavity problem, etc.). However, long-term continuous release of an exudate from the ground bone surface, mucosa or the tissues surrounding the surgical wound may follow surgery. This results in delayed drying of the grafted tissue and has been known to cause hematoma and even subsequent infection in the retroauricular region.
In this study, a continuous drainage tube was implanted subcutaneously in the retroauricular region of 17 patients who had undergone surgery for mastoid cavity obliteration, and was left in place for a number of days. As a result, drying of the surgical wound and the inner ear was achieved within a short period of time.
