Abstract

Introduction: Aesthetic applications of botulinum toxin type A (BoNT-A) may lead to some complications, including unwanted muscle paralysis. Moreover, BoNT-A effects may last several months, and there is no medical intervention so far to accelerate muscle function recovery. Case Report: A female patient with a movement disorder of the mimic muscles resulting from BoNT-A injections received daily sessions of photobiomodulation therapy (PBMT). A fast improvement in both facial asymmetry and muscle function was noted within a few weeks. After nine weeks, almost complete recovery was achieved. Conclusion: According to the current case, PMBT seems to be an effective intervention to accelerate muscle function recovery following BoNT-A use.
