Laser treatment of port wine stains / 中华整形外科杂志

<p><b>OBJECTIVE</b>To assess the efficiency of the PDL in the treatment of PWS in Chinese patients with skin type III-IV.</p><p><b>METHODS</b>252 patients with PWS at different anatomical sites were retrospectively studied. A flashlamp-pumped pulsed dye laser was used. The differences in therapeutic effect of laser were analyzed in the following ways: (1) by dermatomal distribution of face and neck; (2) by anatomical subdivision of face; (3) by the size of the lesion. The therapeutic effect was graded as 0 < or = poor < 25%, 25% < or = fair < 50%, 50% < or = good < 75%, 75% < or = excellent < or = 100%.</p><p><b>RESULTS</b>It revealed that the lesions at neck had the best response. The dermatome II zone showed the least response to PDL. Among the anatomical subdivision of face, the frontal area had the highest clearance, while the zygoma and cheek had the lowest clearance. Patients with PWS on the extremities respond less favorably with the fair lightening effect. Furthermore, the mean lightening was decreased as the size of PWS was increased.</p><p><b>CONCLUSIONS</b>The response difference of PWS to PDL was not only related to the anatomical region, but also related to the lesion size. It is imperative to give the patients rational treatment suggestion and normal expectation.</p>

Application of fractional laser resurfacing in the treatment of superficial scar / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study the therapeutic effect, safety and risk of fractional resurfacing with ablative laser in the treatment of superficial scar.</p><p><b>METHODS</b>88 cases of superficial scar, including 66 cases of acne scar, 12 cases of burn scar and 10 cases of other scar, were treated. All the patients were treated with Pixel (Er:YAG 2940 nm, > or = 3 times), or Encore (Ultrapulse CO2 10600 nm, > or = 2 times), or a combination of Pixel and Encore( > or = 3 times).</p><p><b>RESULTS</b>The therapeutic effect of treatment was graded as medium when the scar was improved > 25%, as good when the scar was improved > 50%. The effective result was achieved in 80% of the patients. Good effect was achieved in 50% of the patients. There were 244 treatments of Pixel and 86 treatments of Encore. Persistent hyperpigmentation was happened in one case with Encore treatment, which relieved four months later. No other complication was happened.</p><p><b>CONCLUSIONS</b>The fractional resurfacing with ablative laser is an effective method for superficial scar, especially acne scar. It is mini-invasive with low risk. The key mechanism is the ability of enhancing the tissue remodeling induced by heat effect of laser.</p>

Rhinoplasty in Chinese: management of lower dorsum and bulbous nasal tip / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Bulbous nasal tips and lower dorsa are common facial features in Chinese people, and surgery to reshape these is frequently requested. The use of silicone implants in rhinoplasty has been widely used in China for many years, but is not suitable for patients seeking Caucasian tip shapes. The creation of an excessively high tip supported only by a silicone implant inevitably leads to implant extrusion. Although many rhinoplasty techniques have been used in Caucasian patients, there is currently no suitable method for Chinese patients, whose anatomy differs from that of Caucasians. The present study was aimed to investigate the clinical outcome of a novel method of rhinoplasty in Chinese people.</p><p><b>METHODS</b>Eighty patients underwent rhinoplasty using our method between 2002 and 2006. We classified the patients into three types, according to the distance between tip defining points, and used different techniques accordingly. Furthermore, an innovative cartilage carving method and a tip fibro-fatty tissue flap were designed and combined with traditional techniques, such as insertion of silicone implant, cartilage grafts, suture techniques and cephalic trimming to reshape the nasal contours. The followup period was 10 - 60 months (average, 21 months).</p><p><b>RESULTS</b>Remarkable modifications in nasal contours were achieved. No complications developed in any of the 80 patients. Seventy-eight patients were satisfied with the results. The outcomes remained unchanged over time.</p><p><b>CONCLUSION</b>Our method is effective and suitable for the treatment of Chinese patients with lower dorsa and bulbous nasal tips.</p>
