Abstract

Orthognathic surgery can sometimes cause sensory disturbances in the orofacial region. The objective of study was to evaluate effects of photobiomodulation therapy (PBMT) in a treatment of a 24-year-old female patient who experienced decreased chin and lower lip sensation following orthognathic surgery performed two years earlier. PBMT using +/- 10a808nmdiode laser was administered over nine clinical sessions. The dosimetry used consisted of power 0.1W of power, energy per point,of exposure time/point of 30 seconds per spot in continuous mode and 69.762ofJ/cmenergy density. The treatment protocol involved irradiation of the extraoral pathway of the inferior alveolar nerve. In addition, nine points were selected for the ofapplicationthelaser on the chin and four points on the inner and outer surface of the lower lip. The patient reported a significant improvementsoryinsen perception, indicating an almost complete recovery of sensation in the affected area. This case highlights the potentialcyofefficaPBMT in restoring sensory function, even in cases where sensory deficits persist long after surgery.
