Adjunctive Low-Intensity Pulsed Ultrasound Therapy for Bone Regeneration Following Jaw Cyst Enucleation With Curettage.

OBJECTIVE

This trial aimed to assess the adjunctive therapeutic effect of low-intensity pulsed ultrasound (LIPUS) in promoting bone regeneration following jaw cyst enucleation with curettage.

METHODS

This triple-blinded, randomized trial enrolled 29 patients (33 jaw cysts) undergoing enucleation. 17 patients (18 cysts) received daily LIPUS therapy for 10 days (Ultrasound group), while 12 patients (15 cysts) received sham LIPUS therapy (control group). Volumetric changes of the cystic cavities and bone density (relative Hounsfield units) were assessed at baseline, at 3, and 6 months following LIPUS therapy.

RESULTS

At the 3rd month, a significant reduction in cyst volume was observed in the Ultrasound group, which showed a 63% reduction, compared to a 35% reduction in the control group (p = 0.031). By the 6th month, the Ultrasound group demonstrated a further decrease in volume compared to the control group (82% vs. 61%; p = 0.027). Moreover, LIPUS therapy consistently resulted in significantly greater bone density than the control group at both 3 and 6 months (p = 0.026 and p = 0.031, respectively).

CONCLUSIONS

Adjunctive LIPUS therapy following jaw cyst enucleation improves bone regeneration postoperatively without adverse effects. LIPUS is a promising non-invasive method for promoting bone healing post-enucleation.
