Otitis media initially involves only the mucosa, but if unchecked, may eventually spread to bone, causing bony erosion and severe osteitis that can have life-threatening CNS complications. Placement of a PE tube generally is all that is necessary to eliminate middle ear fluid and restore normal hearing in serous otitis media and adhesive otitis media. Mastoidectomy is required in more advanced chronic ear disease; if disease is not too extensive, hearing may be restored by tympanoplasty.
中耳炎最初仅累及黏膜，但如果不加以控制，最终可能蔓延至骨质，导致骨质侵蚀和严重骨炎，进而引发危及生命的中枢神经系统并发症。在浆液性中耳炎和粘连性中耳炎中，通常只需置入中耳通气管即可消除中耳积液并恢复正常听力。对于更严重的慢性耳部疾病，则需要进行乳突切除术；如果病情不太广泛，可通过鼓室成形术恢复听力。
