Statistical analysis shows that the regular use of silastic sheet in all cases of extensive defects of the middle-ear mucosa (ensuring a mucosa-lined space) or advanced inflammatory changes (draining the cavity and tube) can eliminate negative influences of pathological conditions of the middle-ear on the long-term functional results, provided the sheet is removed when the remaining air-bone gap within the main speech range exceeds 10 dB after the ear has healed. Resorbable gelatin film implants should be used in minor inflammatory changes, less extensive mucosal defects, and subtotal perforations of the drum.
统计分析表明，在所有中耳黏膜广泛缺损（确保有黏膜衬里的空间）或晚期炎症改变（引流中耳腔和咽鼓管）的病例中，定期使用硅橡胶片可消除中耳病理状况对长期功能结果的负面影响，前提是在耳部愈合后，主要言语频率范围内剩余的气骨导差超过10 dB时取出该片。可吸收明胶膜植入物应用于轻度炎症改变、较不广泛的黏膜缺损以及鼓膜的次全穿孔。
