医学研究虽然没有彻底查明儿童分泌性中耳炎的病因，但发现主要与咽鼓管功能障碍、感染和免疫反应等三大因素密切相关。其中，咽鼓管功能不良是主要原 因。在儿童中，腺样体肥大是引起咽鼓管阻塞或咽鼓管功能不良的最常见原因。此外，本病常继发于急性上呼吸道感染，极可能是中耳的一种轻型的或低毒性的细菌 感染。最后，由于中耳是独立的免疫防御系统，在儿童期尚未发育成熟，这也是儿童易患本病的重要原因之一。
研究结果显示，咳嗽和打喷嚏不会使鼻膜黏液跑到鼻窦中，但是擤鼻涕却会使鼻膜黏液充满鼻窦，使得鼻窦变成病原菌滋生的温床。因此，感冒鼻分泌物较多 时，家长应教会宝宝先擤一侧鼻孔，再擤另一侧鼻孔，切勿同时捏住双侧鼻孔擤鼻涕，以防鼻涕和细菌经咽鼓管进入中耳。小儿模仿力很强，家长应注意自己擤鼻涕 的行为是否正确。
