| Research Abstract |
We evaluated the effectiveness of the stellate ganglion blockade(SGB) compared with xenon light irradiations(XLI) with neurosensory deficit after orthognathic surgery using current perception threshold(CPT) and Ranged current perception thresholds(RCPT).Because the consent was not taken by the patients, we could not take the fMRI.
CPT and RCPT thresholds in the mental area of 98 sides were measured at stimulation frequency assessing 3 different nerve fiber types before surgery, 1 week after surgery and after treatments of 10 times by SGB(29 sides) and XLI(69 sides). These CPT and RCPT values were compared and were evaluated by surgery factor .
The amounts of change of all CPT and RCPT values of the SGB group were significantly decreased than XLI group's after treatment. There was no correlation between CPT and RCPT values and surgery factors.It is concluded that stellate ganglion blockade might be an effective method for treatment of neurosensory deficits after the orthognatic surgery.
