Bone pâté obliteration or revision mastoidectomy: a five-symptom comparative study.

A survey of 47 patients who underwent surgical treatment for persistent symptomatic mastoid cavities following mastoidectomy for cholesteatoma, was carried out. There were two groups comprising 26 patients who underwent revision mastoidectomy (14 with meatoplasty); the technique favoured early in the series, and 21 managed by mastoid revision and obliteration with autologous bone pâté and a superiorly based temporalis musculo-periosteal flap. A questionnaire was used to assign a symptom score to each patient's pre and post-operative condition, with a maximum score of 15 and minimum of zero. The pre-operative scores for the two groups were not significantly different, but the patients treated by obliteration with bone pâté had a significantly lower (P = 0.05) postoperative symptom score than those who had their mastoids simply revised. This study suggests that revision mastoidectomy with bone pâté obliteration achieves a more favourable result than revision mastoidectomy alone, and is, we believe, the technique of choice for the patient with a symptomatic mastoid cavity.
