Reconstruction of old radical cavities.
Various techniques and materials have been proposed to deal with problems connected with radical cavities including recurrence of inflammatory processes, requirement of regular medication, social inconvenience (i.e., inability to practice any water sport, work in adverse environment, etc.). The present paper details the results of revalidation of old radical cavities using as filling a mixture of tricalcium phosphate and hydroxyapatite granules. Three techniques were used in reconstruction of the posterior canal wall. In the first procedure, the material was incorporated with fibrin adhesive to fill the cavity. In the other two methods the ceramic granules were covered respectively with a sheet of bone pate-fibrin sealant or with septal cartilage homografts. Twenty-four patients with chronic discharging old radical cavities were operated with anatomic results of 91.7 percent successful graft taken. The functional results showed an air-bone gap less than 30 dB in 72.7 percent of the cases after 6 months. After 2 years hearing gain was satisfactory in 63.6 percent of the patients. The different methods of reconstruction of posterior canal wall did not influence these findings.
