EFFECT OF PHOTOBIOMODULATION THERAPY ON NEUROSENSORY RECOVERY OF THE LOWER LIP AND CHIN AFTER BILATERAL SAGITTAL SPLIT RAMUS OSTEOTOMY COMBINED WITH GENIOPLASTY: A PILOT STUDY

Abstract

This research is a pilot study to investigate the effect of photobiomodulation on neurosensory recovery after bilateral sagittal split ramus osteotomy combined with genioplasty in 4 patients. On the randomly selected side, 660 nm laser wavelength, 100 mW power, and 8 J/cm2 energy intensity were applied to the oral cavity, lips, and chin, totaling 19 points, 6 times, 1 week apart each time. The control side was not exposed to light, but the laser head position was the same. They were evaluated using the total scores from the visual analog scale and the neurosensory test for a total of 8 time periods. The study's results found that overall, there were no differences in the 4 patients' total scores at different time periods. It was concluded that the use of photobiomodulation at these parameters was not effective in neurosensory recovery of the lower lip and chin after bilateral sagittal split ramus osteotomy combined with genioplasty.
