To evaluate the safety and efficacy of a 980 nm diode laser for the treatment of benign facial pigmented and vascular lesions, and in oral surgery.
20 patients were treated with a 980 nm diode laser. Oral surgery: 5 patients (5 upper and lower frenulectomy). Fluence levels were 5-15 J/cm(2); pulse lengths were 20-60 ms; spot size was 1 mm. Vascular lesions: 10 patients (5 small angiomas, 5 telangiectases). Fluences were 6-10 J/cm(2); pulse lengths were 10-50 ms; spot size was 2 mm. In all cases the areas surrounding the lesions were cooled. Pigmented lesions: 5 patients (5 keratoses). All the lesions were evaluated by dermatoscopy before the treatment. Fluence levels were 7-15 J/cm(2); pulse lengths were 20-50 ms; spot size was 1 mm. All the patients were followed at 1, 4 and 8 weeks after the procedure.
Healing in oral surgery was within 10 days. The melanoses healed completely within four weeks. All the vascular lesions healed after 15 days without any residual scarring.
The end results for the use of the 980 nm diode laser in oral and facial surgery appears to be justified on the grounds of efficacy and safety of the device, and good degree of acceptance by the patients, without compromising their health and function.
评估 980nm 半导体激光治疗良性面部色素性和血管性病变及口腔外科的安全性和疗效。
对 20 例患者采用 980nm 半导体激光进行治疗。口腔外科:5 例患者(5 例上、下唇系带切除术)。能量密度 5-15J/cm²;脉宽 20-60ms;光斑 1mm。血管性病变:10 例患者(5 例小型血管瘤,5 例毛细血管扩张)。能量密度 6-10J/cm²;脉宽 10-50ms;光斑 2mm。所有病变周围区域均予冷却。色素性病变:5 例患者(5 例角化病)。所有病变在治疗前均经皮镜检查。能量密度 7-15J/cm²;脉宽 20-50ms;光斑 1mm。所有患者均在治疗后 1、4、8 周进行随访。
口腔外科手术 10 天内愈合。色素沉着在 4 周内完全愈合。所有血管性病变在 15 天内愈合,无任何残留瘢痕。
980nm 半导体激光在口腔和面部手术中的应用效果良好,安全性高,患者接受程度好,不会影响其健康和功能。
