| Summary: | Objective: To report 2 cases of patients with oral lichen planus (OLP), with involvement of the cheeks, with reduced mouth opening, successfully treated with a single radiofrequency session.
Cases Presentation: A 55-year-old and 56-year-old female patients with OLP and trismus were treated with a handpiece that works with a frequency comprised between 500 kHz and 1 MHz. Parameters used were: first case – biostimulation with application of monopolar capacitive technique software muscle hypotonia, at the power of 29%, for 10 minutes; biostimulation with bipolar resistive technique software contractures power 20%, 10 minutes. Second case –biostimulation with application of monopolar capacitive technique software muscle hypotonia, at the power of 17%, for 10 minutes; biostimulation with bipolar resistive technique software contractures power 20%, 10 minutes.
Results: Patients increased the mouth opening respectively of 6 mm and 8 mm and pain disappeared.
Conclusions: The use of radiofrequency in the treatment of trismus associated with potentially malignant diseases could be a safe and effective tool, although further studies are needed to confirm these preliminary data.
