Orofacial granulomatosis treated with low-level laser therapy: a case report

Objectives We report a case of orofacial granulomatosis successfully treated with low-level laser therapy (LLLT). Study design LLLT was delivered through a diode laser device (Lasemar Eufoton, Trieste, Italy) with the use of a 4-cm defocalized lens and power of 1 W. Treatment was administered in sessions of 5 irradiations of 1 minute each, with a 1-minute interval between 2 subsequent irradiations (power density 0.08 W/cm 2 ; fluence/application: 4.8 J/cm 2 ; fluence/session: 24 J/cm 2 ). Laser therapy was repeated 12 times (3 times per week). Results After 2 weeks of LLLT applications, the patient reported an improvement of symptomatology as well as a decrease of labial swelling. Complete healing was observed after 1 month. The patient was followed for 2 years. No recurrence of swelling was observed during the follow-up. Conclusions Advantages of the LLLT approach include an absence of side effects, analgesic properties (usually reported after first application), and good patient compliance.
