“…In 1911 Mosher described Plummer's technique of using a soft tissue flap to fill the excavated mastoid 2 . Many others including Popper, 3 Meurman and Ojala, 4 Guildford, 5 Palva 6 and the Hong Kong flap 7 have been described along with various fillers. Fat, cartilage, bone chips/pate have been used but they tend to resorb with time and although one could "overfill" to compensate, the results are unpredictable and some authors have raised concerns that using cortical bone could result in cholesteatoma becoming incorporated into the obliterated cavity.…”
