With a purpose of collecting shortcomings of the current mastoid obliteration, we tried two methods with autgraft tissue. The one utilized the combined grafts with a bone tip from the iliac crest and the temporal muscle. The other is a new technique utilizing the temporalis osteomuscular flap.Major characteristics of the latter method are as follows. 1. "Living bone" is transplanted for reconstruction of the osseous external auditory meatus. Therefore, the bone is safely implanted without being absorbed. 2. This flap is not so atrophied because its vasculo-neural supply remains intact. 3. Since only the fascia for tympanic membrane is utilized as a free graft, there is a less chance of graft failures. 4. The fascia is contacted with the bone with enough blood supply, so its early take can be expected. 5. As the muscle and the bone are in a body, easier reconstruction of the auditory meatus is possible than the use of a free bone fragment.
