Abstract

Medication-Related Osteonecrosis of the Jaw (MRONJ) therapy remains an unresolved problem. The proposed conservative and surgical treatment regimens are associated to contradictory success rates. Surgical approach with Er:YAG laser is associated to significant better results compared to medical treatment and traditional surgical approaches. Objective: To describe a new surgical approach that couples the advantages of the Er:YAG laser and the usefulness of the AF in highlighting surgical margins. One of the difficulties encountered during surgical removal of a MRONJ is the precise individuation of necrotic bone margins. Case Report: A case of Stage III mandibular osteonecrosis treated with a new surgical approach is presented. The aim is to describe an auto-fluorescence (AF) guided surgical approach performed with Er:YAG laser and Nd:YAG Low Level Laser Therapy (LLLT). After one month of follow-up, the complete mucosal healing was evident and symptoms was unobserved. Such a technique allowed a highly accurate and minimally invasive approach through the selective ablation of the non-/hypofluorescent areas. Conclusion: Taking into account the advantages of laser therapy and the possible effectiveness of the AF in highlighting surgical margins, this approach would probably achieve excellent outcomes.

Abstract

The new technology such as the neodymium-doped yttrium aluminum garnet (Nd:YAG) laser has been used for oral soft tissue surgery. Previous study shown that laser surgery resulted in lower morbidity and complication rates. Objective: This study aims to evaluate the differences in the post-operative course associated to the use of Nd:YAG laser and to cold blade after oral soft tissue surgery. Methods: One-hundred and eighteen comparable surgical interventions were evaluated. Group 1 (G1) included 77 interventions performed with Nd:YAG laser; group 2 (G2) 41 with cold blade. Acute post-operative pain was evaluated with visual analogue scale (VAS), numeric rating scale (NRS) and verbal rating scale-6 (VRS-6) on the same day of surgery, and at 1, 3 and 7 days after surgery.The HRQoL was evaluated on day 7 using a 0-45 score range questionnaire. Data were analyzed using the software STATA 12 (StataCorp LP, College Station, Texas, USA). Results: No statistically significant differences could be highlighted in VAS and NRS scores. The VRS-6 scores resulted statistically significant at days 1 and 3. At day 1, 47.14% of patients in G1 and 13.16% in G2 had no pain; at day 3, 62.86% in G1 and 21.05% in G2 had no pain. The HRQoL in G1 was statistically higher than G2. Conclusion: The better HRQoL and the lower post-operative pain observed in laser-treated patients may be associated to the possible bio-modulating effect of the laser.
