Outcome of intact canal wall mastoidectomy in limited attic cholesteatoma
Keywords:Canal wall up . Intact canal wall . Atticotomy . Attic reconstruction.
Background: Surgery for cholesteatoma has evolved over the years in terms of efficacy and patient compliance and better life. Intact canal wall technique is best in terms of normalization of the physiology of the ear along with eradication of disease. Hence this study is undertaken to evaluate a technique of intact canal wall mastoidectomy for limited attic cholesteatoma and to study practical considerations during surgery.
Methods: Any person undergoing surgery for attic cholesteatoma has to be thoroughly examined during surgery and decision for doing a canal wall up (CWP) surgery will be taken on the operating table. The patients were regularly followed up and microscopic, otoendoscopic and audiological assessments done at regular intervals. Revision surgery was done only if there were signs of recidivism or if ossiculoplasty was planned for second stage or placement of prosthesis later was considered.
Results: Out of 100 cholesteatoma surgeries, 22 cases found suitable for the CWU technique. Only 1 out of 22 patients required revision surgery due to recurrence. Rest of the patients maintained healthy middle ear for more than a year. Prevention of medialization of attic cartilage piece was found to be a very important consideration.
Conclusions: The CWU technique is a reliable method of management for limited attic cholesteatoma. Selection of subjects should be very meticulous.
