Hemostatic Effect of the CO₂Laser Over Excision of an Intraoral Hemangioma

Abstract

Hemangiomas are benign vascular tumors of the endothelial cells and characterized by increased number of normal or abnormal vessels filled with blood. Most true hemangiomas involute with time, but a certain small percentage does not, which may present with complications that require treatment. An estimated 10 to 20% of the true hemangiomas incompletely involute and require ablative treatment. Hemangiomas are probably one of the most underestimated and misunderstood vascular tumors and it is every diagnostician and clinician's imperative to have a sound knowledge of these tumors to thus provide successful treatment to the patients.Conventional surgical excision of hemangioma can cause severe bleeding in the operative site, which on the other hand can be well controlled by the coagulative effect of the CO 2 laser, by virtue of a painless vaporization of the tissue. The purpose of this case study is to understand hemangiomas and the importance and efficacy of the minimally invasive, hemostatic effect of a CO 2 and little postoperative scarring and morbidity in comparison to the conventional surgical techniques.

Fotocoagulação a laser de diodo para tratamento de alteração vascular em lábio: relato de caso

“…Diante disso, diversas modalidades de tratamento foram desenvolvidas e uma série de terapias alternativas ao tratamento convencional tem sido relatada na literatura, incluindo a utilização de corticosteroides orais, crioterapia, agentes esclerosantes, embolização, radiação e laserterapia 27,29,30 .…”

New Trends in Dental Biomechanics with Photonics Technologies

“…Lasers have numerous tissue interactions, such as ablation or vaporization of dental hard tissue [78][79][80][81], hemostasis [82], microbial inhibition and destruction, as well as biological effects, such as biostimulation (photo-bio-modulation), which induce various beneficial therapeutic effects and biological responses, like in bone regeneration in the midpalatal anterior suture [83,84]. In a similar study, it was evaluated the histologic effects of CO2 laser irradiation, during gingival surgery and the histologic effects on cortical bone following irradiation with increasing energy densities [85].…”

Comparison of diode laser in soft tissue surgery using continuous wave and pulsed modes in vitro

“…CO 2 lasers (l = 10.6 μm) are considered the most popular gas lasers [1,[4][5][6][7]. They have been successfully used in general surgery [1], oncology [3][4][5], otorhinolaryngology [1,5], dermatology [6], and dentistry [3,4]. Neodynium-doped yttrium aluminum garnet (l = 1.064 or 1.320 μm) [1,7,8], holmium-doped yttrium aluminum garnet (l = 2.1 μm), thulium-doped yttrium aluminum garnet (l = 1.96 μm) [1,9], and erbium-doped yttrium aluminum garnet (l = 2.94 μm) [1,10], as well as solid-state lasers, are frequently used for soft tissue surgery.…”

“…Lasers are widely used for soft tissue surgery [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], because they effectively cut soft tissues with good hemostasis [1][2][3]. CO 2 lasers (l = 10.6 μm) are considered the most popular gas lasers [1,[4][5][6][7].…”
