Endaural tympanoplasty without flap : a report on 34 cases

The most carefully planned and executed operation on the ear is a failure as far as the patient is concerned if the cavity collects debris and discharges for months and years afterwards. According to Mawson (1967), twenty-five per cent of radical mastoid cavities fail to heal, remain infected and discharge persistently after operation. Of 428 tympanoplasties done by Portmann (1963) between 1959 and 1962, only 75 per cent achieved perfectly dry cavities.peer-reviewe
