Surgical treatment of oral lymphangiomas with CO2 laser: report of two uncommon cases

Abstract

This paper reports the treatment of oral lymphangiomas with carbon dioxide CO₂ Laser. Lymphangiomas are rare congenital lymphatic malformations. These lesions are most frequently diagnosed during childhood, are most commonly located in the head and neck region, and are extremely rare in the oral cavity. Oral lymphangiomas are of complex treatment due to the difficulty in performing a complete excision. CO₂ laser is the most often used laser in the oral cavity due to its affinity with water and high absorption by the oral mucosa. Several benefits of the use of CO₂ laser have been reported for surgical oral procedures. The cases reported herein were biopsy-proven lymphangiomas of the oral cavity. The surgical procedures were carried out under local anesthesia and a focused CO₂ laser beam (λ10.600 nm, Φ ~2 mm, CW/RSP) was used. At the end of the surgery, the laser beam was used on a defocused mode to promote better hemostasis. Neither sutures nor dressings were used after surgery. No medication and only mouthwashes were prescribed to all patients on the postoperative period. There were no postsurgical complaints from the patients and no relapses of the conditions were observed after follow-up periods of 12 and 18 months. The use of CO₂ laser was practical, easy to carry out and effective on the treatment of oral lymphangiomas, with no lesion recurrence.

Treatment of Epulis Fissuratum with carbon dioxide laser in a patient with antithrombotic medication

“…Additional and important advantages of CO 2 lasers, as observed in the present case, are the cutting precision, the uniqueness of its non-contact technique and the reduction of postoperative complaints such as pain, infection and edema (2,20,22). Regarding the size of the lesions of this case, it is remarkable that pain was absent during the intraoperative and postoperative periods.…”

“…Carbon dioxide (CO 2 ) laser emits energy at a 10.6 µm wavelength (infrared zone), which is absorbed by water. The high water content of the oral soft tissues makes this laser a useful tool in oral soft surgery with several advantages including excellent hemostasis, high precision in tissue destruction, no need for sutures, non-contact surgery, wound sterilization and minimal postoperative pain and edema (11)(12)(13)(14)(15)(16) additional benefit in oral surgery for patients that suffer from clotting disorders (17).…”

Cryotherapy for the management of a lip lymphangioma – a case report and literature review

“…In particular, the microcystic category as those that do not respect tissue planes due to their diffuse nature causing challenges in surgical excision, whereas macrocystic lesions, which typically present below the mylohyoid, are usually localised and therefore more successfully surgically removed. Partial or incomplete removal of these lesions is associated with high recurrence rates and approximately 50% of these cases will relapse within 2 years, whereas total removal carries a 7% recurrence rate.…”

Lymphohemangioma on Hard Palate: Case Report

“…The lymphangioma is a relatively uncommon. In a study by Rocha [8] was evaluated the prevalence of benign oral tumors in the Pathology Department of the Federal University of Rio Grande do Norte for 21 years . From the 336 diagnosed neoplasias, the lymphangiomas represented only 1.5% of the cases.…”

“…90% of the cases are found up to 2 years old, being rare in adults [4][5][6]. They are usually floating soft lesion, and a secondary bleeding into the interior of the lymph spaces may result in a purplish color of these vesicles [7][8][9][10]. These lesions could be associated with hemangiomas revealing their hamartomatous condition [3,10].…”
