Role of surgery in tuberculous mastoiditis.

A study was undertaken in 43 patients to determine the role of surgery in tuberculous mastoiditis. Cortical mastoidectomy was performed on five patients (Group I). Incision and drainage of a post-auricular abscess, removal of sequestrum and meatoplasty in eight (Group II). Thirty patients had no ear surgery (Group III). Of the 17 patients with facial palsy, three were in Group I, two in Group II, 12 in Group III. The patients in all three groups were treated with anti-tuberculous drugs for a period of no less than six months. The average time taken for the otorrhoea to subside and granulation tissue to resolve completely was two months in all three groups. The facial nerve recovery in the non-operated ears (Group III) was 92 per cent and in the operated ears (Group I and II) 80 per cent. The conclusion is that chemotherapy is the management of choice in tuberculous mastoiditis. The only role of surgery is incision and drainage of a post-auricular abscess and removal of sequestrum if present.
