Longitudinal Hearing Outcomes between Inlay Butterfly Cartilage and Underlay Fascia Tympanoplasty

比較軟骨內置型與筋膜下置型鼓室成型術聽力結果之縱向研究

摘要


BACKGROUND: Few studies in the literature have addressed comparing longitudinal hearing results between inlay cartilage and underlay tympanoplasty.METHODS: A total of 60 ears of 54 patients were enrolled. The mean follow-up time of short term and long term hearing examination was 182.64 and 565.67 days.RESULTS: 0.25K, 0.5K and 4K significantly improved in short-term and long-term results (p < 0.05) for inlay group and 0.25 K, 0.5 K and 1 K in short-term and long-term results (p < 0.05) for underlay group. The postoperative ABGs significantly improved at 0.5 K, 1 K and 4 K in short-term and long-term hearing tests for inlay group and only in long-term for underlay group.CONCLUSIONS: The acceptable hearing results were achieved in short-term period and improved ABG closure ratios continued to increase over time for both groups. Frequency-specific hearing improved at 0.25 K, 0.5 K, and ABG closure increased at 0.5K, 1 K and 4 K in long-term result for both groups.
