    Abstract:
    OBJECTIVE: We aimed to analyze preoperative and intraoperative clinical characteristics of chronic perforated otitis media by patient age. MATERIALS AND METHODS: We analyzed 137 tympanoplasties for chronic perforated otitis media in 133 patients. Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15-39 years), a middle group (40-64 years), and an elderly group (≥65 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air-bone gap at frequencies of 250 Hz and 500 Hz among the three age groups. RESULTS: Although type I tympanoplasty was performed most frequently in all age groups, it was performed significantly less often in the elderly group (p<0.05). The mean mastoid pneumatization index was significantly lower in the elderly group (p<0.05). Preoperative air-conduction hearing and bone-conduction hearing differed significantly among age groups (p<0.05 for both). There were no significant differences in the air-bone gap among the three groups. The mean patch effect was significantly better in the younger group than in middle or elderly groups (p<0.05). CONCLUSION: The less pneumatized mastoid and ossicular diseases in elderly patients with chronic perforated otitis media suggest that they had longer lasting and more severe childhood middle ear pathologies than did younger patients.
