CO2 Laser Surgery of Obstructive Fibroma in the Oropharyngeal Cavity
Niccoli-Filho, Walter/Cantarelli Morosolli, Aline Rose/Bianchi, Michelle
Fibroma is the most common tumor of the oral cavity. This lesion is a hyperplastic proliferation of the oral mucosa and classified as a reactive tumor of fibrous connective tissue. Trauma or irritation from dentures, restorations, or subgingival calculus, cheek biting and suction habits may be factors causing irritation fibroma. The lesion is usually asymptomatic unless secondarily traumatized and ulcerated. Irritation fibroma is treated by surgical excision; additionally, the source of irritation and trauma must be eliminated. In this study, we present a clinical case of bilateral fibroma, the large dimensions of which produced a serious functional impairment, and which was removed using CO2 laser irradiation (0.8 mm focus, 5 W, power density 2.5 W/cm2). The functional and esthetic results suggest that the use of the laser iradiation is a choice to be considered, as it provides a comfortable postoperative period with less edema and no hemorrhaging. Furthermore, it allows the use of a prosthesis immediately after surgery, without the mechanical trauma caused by the suture when placed under pressure by the prosthesis.
