ABSTRACT
Objective:
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 (NdYAG) laser or a combination of erbium-yttrium aluminum garnet (ErYAG) laser. Patients andmethods:
Between June 2015 and March 2017, nine patients, suffering from OVL in the mandibular regions, were treated with NdYAG laser or combination of NdYAG laser and ErYAG laser in our department. The NdYAG 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/cm2. If postoperative scars occurred after the NdYAG treatment, the ErYAG 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.Results:
With single NdYAG 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 NdYAG laser therapy, and then ErYAG laser was used for the scar removal. No mucosal necrosis was found in any of the patients.Conclusions:
The NdYAG laser or combined with ErYAG laser was an effective and safe treatment for patients with OVL in the mandibular region.Palabras clave
