【摘要】Aims: The goal of the present study is to summarize our experience on surgical management of retraction pockets (RP) as a preventive tool against cholesteatomas. Methods: Twenty-five ears have been followed up for a mean period of 6.16 ± 4.35 years (from 1 to 17 years). The sample presented a mean age of 47.56 ± 19.11 years (from 16 to 73 years). All patients underwent cartilage graft surgery. Furthermore 10 (40％) underwent tympanoplasty (TPL) type Ⅰ, 14 (56％) TPL type Ⅱ and 1 (4％) TPL type V. Results: Eleven ears (44％) showed cholesteatoma: all these cases were stage Ⅲ according to Charachon staging, and stage Ⅳ or Ⅴ according to Gersdorff classification. Twelve patients (48％) showed erosion of the ossicular chain. Of these, five were associated with cholesteatoma and seven only with retraction. The recurrence rate of cholesteatoma was 12％. None of the patients with a stage Ⅱ or Ⅲ RP (according to Gersdorff classification) developed cholesteatoma. The recurrence of RP was 0％. In regards to literature review, seven references were selected. These studies showed a success rate ranging from 79.1％ to 88％, while recurrences of RP varied from
