The purpose of this study was to analyze the results of the long-term follow up of the 325 ears operated upon during the 11 years from 1968 to 1978. According to the 166 patients who answered our questionnaire, ear discharge was complained of in 45 percent of the cases and hearing deterioration in 65 percent thereof.In a total of 115 ears, on which we were able to carry out otoscopic examination and pure-tone audiometry, 49 percent underwent surgery for cholesteatoma; 42 percent, for chronic supperative otitis media; 4 percent, for tuberculosis of the middle ear; and 5 percent received surgery a second time on the middle ear. Of those, 46 ears underwent intact canal wall tympanoplasty; 32 ears, classical tympanoplasty; 19 ears, modified radical mastoidectomy; and 18 ears, radical mastoidectomy.Recurrence of perforation of the reconstructed ear drum was found in 44.7 percent and recurrence of ear discharge was present in 43 percent of the total; in 61 percent of the ears that had received radical mastoidectomy, in 47 percent of those with modified radical mastoidectomy in 56 percent of those with classical tympanoplasty and in 24 percent of those with intact canal wall tympanoplasty. Long-term hearing results were unsatisfactory; only 18.4 percent of the patients experienced improvement in postoperative hearing but postoperative hearing was depressed in 40 percent of the cases.
