Abstract
Neurosensory disturbances (NSD) are common after genioplasty. In this study we aimed to assess the recovery of NSDs with or without leukocyte- and platelet-rich fibrin (L-PRF) following genioplasty. In this double-blind, split-mouth, randomised clinical trial, L-PRF was applied around the mental nerve at the osteotomy site in genioplasty (treatment side). The contralateral side was considered the control side. Two-point discrimination (TPD) test, brush test, and self-reported NSDs (SR-NSD) were used to determine NSD at one, four, and 12 months after genioplasty. Twenty patients were studied. At one and four months after osteotomy, the mean scores of TPD and SR-NSDs were significantly different between the treatment and control sides (p = 0.04, p = 0.01, respectively). The mean of TPD and SR-NSDs was not statistically different on both sides 12 months after operation (p = 0.05, p = 0.71, respectively). The application of L-PRF may enhance the speed of NSD recovery four months after genioplasty.
