摘　　要：应用半导体激光和Ｎｄ：ＹＡＧ激光照射１０ 只家兔的鼻腔粘膜，用光镜和扫描电镜观察粘膜上皮修复情况。结果表明，术后２４、７２ｈ 以炎性反应为主，术后７ｄ 开始修复，术后２ 个月粘膜基本修复，重新覆盖纤毛柱状上皮，恢复鼻腔生理功能。半导体激光比Ｎｄ：ＹＡＧ激光损伤轻，易控制，操作方便。The nasal mucosa of ten rabbits were irradiated by Diomed 15 diode laser and Nd:YAG laser. The epithelium repair of nasal mucosas were observed under light microscope and scanning electron microscope. The results indicated that there were inflammatory cells infiltration and necrosis at 24 hours and 72 hours after surgery. At 7 days after surgery, the epithelium began to repair. At 2 months after surgery,the injury area was covered by cilliated columnar epithelium. The nasal function recovered to normal. Compaired with Nd: YAG laser, Diomed 15 diode laser has more superiorities in clinical application.
