Abstract
Chronic suppurative otitis media (CSOM) without cholesteatoma, the surgical treatment of which is still controversial, is a common diagnosis in otologic practice. A retrospective analysis of 323 patients who underwent surgery for noncholesteatomatous chronic otitis media in the Gruppo Otologica, Piacenza, Italy, between April 1983 and December 1993 is presented. Cases were separated Into three groups according to different surgical treatment modalities and conditions of the ears at the time of operation. Group I (n = 53) consisted of cases of CSOM treated by tympanoplasty without mastoidectomy (TLWOM). Group II (n = 28) included cases of CSOM treated by tympanoplasty with mastoidectomy (TLWM). Intact canal wall technique was used in these cases. The ears in both these groups were discharging severely at the time of surgery. Group III (n = 242) included patients whose ears were dry at the time of surgery but who had had previous recurrent episodes of suppuration and who were treated by TLWOM. At the last follow-up, graft success rates for groups I, II, and III were 90.5%, 85.7%, and 89.2%, respectively, and mean residual gaps were 17.2 dB, 20.1 dB, and 19.4 dB, respectively. There was no statistically significant difference between the three groups either on graft success rates (p > 0.05) or on final functional hearing outcome (p > 0.05). TLWM is the preferable treatment modality for most surgeons in noncholesteatomatous CSOM. Nevertheless, in our experience TLWOM yields comparable results for this group of patients. In addition, we could not find any significant difference in results of graft success and final functional hearing rates between dry and discharging ears (p > 0.05).
