摘要
目的 研究应用KTP(5 32nm)激光治疗咽喉良性肿瘤性疾病的可行性及适应证的选择。方法 治疗对象为 2 7例咽喉血管瘤、囊肿等肿瘤性疾病患者。治疗取仰卧位 ,经喉插管供氧 ,行全身静脉麻醉 ,支撑喉镜下暴露咽喉腔病变 ,在显微镜下将KTP激光瞄准光斑调到病变部位。对于可切除病变 ,将光斑直径调节到 0 2mm ,气化切割病变 ;对于不可切除的 ,将光斑直径调节到 2mm左右或降低输出能量凝固病变。结果 2 7例患者均经 1次治疗痊愈。术后随访 1～ 3年 ,无复发。结论 显微镜下KTP激光手术治疗咽喉良性肿瘤性病变损伤小 ,治愈率高 ,具有良好的应用前景。
Objective To evaluate the feasibility and indication of treatment of pharyngeal and laryngeal benign tumors with KTP (532 nm) laser. Methods 27 cases of pharyngeal and laryngeal benign tumors were treated with KTP laser. Among them, 12 cases were cyst, 11 cases were hemangioma, etc. The diameter of tumors was 2～6 cm. After general anesthesia through laryngeal intubation, pharyngeal and laryngeal cavity was exposed with suspension laryngoscope. When the tumor was excised with KTP laser, the aiming spot was focused at the lesion under microsecope. The spot size was 0 2 mm in diameter for resectable lesions. For treatment of unresecteble lesions, a laser beam spot of 1-3 mm in diameter or a decreased output power was used. Results All tumors in the 27 patients were cured by one treatment. No relapse occurred affter 1-3 years follow up. Conclusions Benign tumor can be exposed and cut clearly with KTP laser under microscope. No bleeding occured during the operation. Our results indicate that this KTP laser treatment of binign pharyngeal and laryngeal tumors is safe and reliable with minimal injury and deserves recommendation.
