The aim of the present study was to investigate the clinical treatment effect on oral venous lakes (OVL) treated with neodymium-doped yttrium aluminum garnet (Nd:YAG) laser or a combination of erbium-yttrium aluminum garnet (Er:YAG) laser. Between June 2015 and March 2017, nine patients, suffering from OVL in the mandibular regions, were treated with Nd:YAG laser or combination of Nd:YAG laser and Er:YAG laser in our department. The Nd:YAG laser was mainly performed for the treatment of nine initial lesions. The preset parameters were as follows: average power of 5 W, frequency of 100 Hz, microshort pulse (MSP), tip size of 300 μm, spot size of 3 mm, irradiation distance of 3-4 mm, and speed of 1-2 mm/sec, sequential treatment. The power density at work was 57 W/cm. If postoperative scars occurred after the Nd:YAG treatment, the Er:YAG laser was used. The parameters were set as follows: power of 3.75 W, energy of 150 mJ, frequency of 25 Hz, very long pulse (VLP), tip size of 0.6 mm, 40% water, and 60% gas. The patients were followed up for 4-8 weeks. The therapeutic results were graded on a 4-point scale system. Adverse effects after laser treatment were evaluated and managed accordingly. With single Nd:YAG laser, the therapeutic outcome was excellent in seven patients (77.8%) and good in two patients (22.2%). Scar tissue was encountered in two patients 2 weeks after Nd:YAG laser therapy, and then Er:YAG laser was used for the scar removal. No mucosal necrosis was found in any of the patients. The Nd:YAG laser or combined with Er:YAG laser was an effective and safe treatment for patients with OVL in the mandibular region.
本研究旨在探讨钕掺杂钇铝石榴石（Nd:YAG）激光或铒钇铝石榴石（Er:YAG）激光联合治疗口腔静脉湖（OVL）的临床疗效。2015 年 6 月至 2017 年 3 月，我科对 9 例下颌区 OVL 患者采用 Nd:YAG 激光或 Nd:YAG 激光联合 Er:YAG 激光治疗。Nd:YAG 激光主要用于治疗 9 个初始病变。预设参数如下：平均功率 5 W，频率 100 Hz，微短脉冲（MSP），尖端尺寸 300 μm，光斑尺寸 3 mm，照射距离 3-4 mm，速度 1-2 mm/sec，顺序治疗。工作时的功率密度为 57 W/cm。如果 Nd:YAG 治疗后出现术后瘢痕，可使用 Er:YAG 激光。参数设置如下：功率 3.75 W，能量 150 mJ，频率 25 Hz，超长脉冲（VLP），尖端尺寸 0.6 mm，40%水，60%气。患者随访 4-8 周。采用 4 分制系统对治疗效果进行分级。根据需要评估和处理激光治疗后的不良反应。
单纯 Nd:YAG 激光治疗后，7 例（77.8%）患者疗效优，2 例（22.2%）患者疗效良。Nd:YAG 激光治疗后 2 周，2 例患者出现瘢痕组织，随后采用 Er:YAG 激光去除瘢痕。所有患者均未见黏膜坏死。
Nd:YAG 激光或联合 Er:YAG 激光治疗下颌区 OVL 是一种有效且安全的方法。
