This paper is devoted to the problem of surgical rehabilitation of patients with the so-called <>. Twenty such patients underwent second operation following sanitization ear surgery for the treatment of recurrent (more than once a year) otorrhoea in the previous period. The operation was performed in two (sanitizing and reconstructive) steps. All the patients were allocated to 3 groups based on the results of preoperative examination and the cause of purulent discharge. Group 1 comprised patients with the <> Eustachian tube, group 2 included patients with the carious-granulation process in the mastoidal part of the cavity, group 3 was composed of patients with the both conditions. Reconstructive surgery in patients of groups 1 and 2 included tympanoplasty (n=7). Four patients of group 2 underwent mastoidoplasty with the use of osteotropic material Stimul-oss, and 9 patients were treated by simultaneous tympano- and mastoidoplasty using Stimul-oss blocks. The outcome of surgical treatment in all reoperated patients was regarded as positive taking into account the absence of purulent discharge from the treated ear and the formation of a small self-purifying cavity. Improved hearing was documented in 15 cases. These results give reason to recommend two-step (sanitizing and reconstructive) reoperation to patients with <> using a surgical procedure chosen individually depending on the cause of purulent discharge.
