鼓室积液的激光显微外科治疗

目的 探讨鼓室积液的激光显微外科治疗方法。方法 应用以色列Sharplan-30C CO2激光器对62例99耳鼓室积液患者进行鼓膜造孔术。结果 单纯鼓膜造孔术18耳，鼓膜造孔维持时间平均2.5周，纯音气导语频区听力较术前平均提高16dBHL；鼓膜造孔同时置通气管81耳，术后跟踪随访3个月以上，纯音气导听力语频区较术前平均提高18.4dBHL。结论 CO2激光治疗鼓室积液为激光在 耳科手术中的典型应用，符合外科手术微创原则，安全性好，非接触式，准确性高，无血操作，术罢清晰，方法简便。

Laser-Assisted Microsurgery for Serous Otitis Media

Objective To discuse the therapeutic role of Laser - assisted microsurgery for serous otitis media, Sharplan- 30C CO2 Laster was used to treat 62 cases (99 ears) with liguid in the tympanic cavity. The laser working model was WP, 2~3 W, 0.1 second, and the tympanostomy size was 2~3 mm in diameter. Simple tympanostomy was performed in 18 ears, and the hole remained open for average 2.5 weeks and the air conduction raised 16 dBHL. For 81 ears, laser - assisted tympanostomy with pressure - equalizing tube insertion was performed, the air conduction raised 18.4 dBHL in 3 month follow up. Conclusion CO2 laser microsurgery is appropriate for serous otitis media, it is a safe, bloodless, easy and effective procedure.
