Thick linear telangiectasia on the ala nasi and nasolabial crease can be resistant to treatment with the potassium-titanyl-phosphate (KTP) laser and the traditional round spot on a pulsed dye laser (PDL). We evaluated the efficacy of a 3 mm x 10 mm elliptical spot using the ultra-long pulse width on a Candela Vbeam(R) PDL for treatment of PDL- and KTP laser-resistant nasal telangiectasia. Nasal telangiectasia resistant to PDL (12 patients) and KTP laser (12 patients) in 18 patients were treated with a 3 mm x 10 mm elliptical spot on the ultra-long pulse pulsed dye laser (ULPDL) utilising long pulse width [595 nm, 40 ms, double pulse, 30:20 dynamic cooling device (DCD)]. Six patients had previously received treatment with both PDL and KTP laser prior to ULPDL (40 treatments, range1-4, mean 2.2). Complete clearance was seen in ten patients, and eight patients displayed more than 80% improvement after ULPDL treatment. Self-limiting purpura occurred with round spot PDL and erythema with KTP laser and ULPDL. Subtle linear furrows along the treatment sites were seen in three patients treated with the KTP laser. ULPDL treatment delivered using a 3 mm x 10 mm elliptical spot was non-purpuric and highly effective in the treatment of nasal telangiectasia resistant to KTP laser and PDL.
鼻翼和鼻唇沟的粗线性毛细血管扩张对钾钛磷酸盐（KTP）激光和传统的脉冲染料激光（PDL）的圆形光斑治疗可能具有抗性。我们评估了 Candela Vbeam（R）PDL 上使用超长脉宽的 3mm x 10mm 椭圆形光斑治疗 PDL 和 KTP 激光抗性鼻毛细血管扩张的疗效。18 例患者中有 12 例对 PDL（12 例患者）和 KTP 激光（12 例患者）具有抗性的鼻毛细血管扩张症采用 3mm x 10mm 椭圆形光斑在超长脉冲脉冲染料激光（ULPDL）上进行治疗，利用长脉冲宽度[595nm，40ms，双脉冲，30:20 动态冷却装置（DCD）]。6 例患者在接受 ULPDL 治疗之前曾接受过 PDL 和 KTP 激光治疗（40 次治疗，范围 1-4，平均 2.2）。10 例患者完全清除，8 例患者在 ULPDL 治疗后显示超过 80%的改善。圆形光斑 PDL 出现自限性瘀斑，KTP 激光和 ULPDL 出现红斑。3 例接受 KTP 激光治疗的患者出现轻微的线性皱纹。使用 3mm x 10mm 椭圆形光斑的 ULPDL 治疗无瘀斑，对 KTP 激光和 PDL 抗性的鼻毛细血管扩张症的治疗效果非常好。
