| Summary: | Introduction:
Persistent otorrhoea and granulation tissue in the mastoid cavity are common post-operative complications of Canal Wall Down Mastoidectomy. In order to avoid the same and to achieve a dry cavity instillation of acetic acid into the mastoid cavity during the post operative period is common practice.
Materials and Methods
In this study we assessed the results of 4% acetic acid instillation in varying quantity and frequency, in the ears after modified radical mastoidectomy.
40 Patients of chronic suppurative otitis media (atticoantral) / cholesteatoma, who underwent modified radical mastoidectomy during one and a half year period, were included in the study. The patients were divided into two groups; Group A with 30 patients and Group B with 10 patients, by simple randomization method. Group A patients were asked to instill 4% acetic acid approximately 10 to 12 drops (generously) into the mastoid cavity thrice a day for 8 weeks and were followed up every week. 10 patients of Group B were asked to instill the same preparation only once weekly and followed up for the next 12 weeks.
Results:
In Group A, dry mastoid cavity was achieved remarkably faster within six to eight weeks and in all the 30 patients. In Group B the results were delayed by up to 4 to 6 weeks in comparison to the Group A patients.
Conclusion:
Though acetic acid instillation is known to help in achieving a dry cavity but a slightly higher concentration (4% acetic acid) used more frequently is highly effective in rendering dry cavity much earlier without proliferation of granulation tissue. |
