ReviewComplications of botulinum toxin A use in facial rejuvenation.
The esthetic application of botulinum toxin type A is a safe treatment modality; nevertheless, complications can occur as a result of patient- and physician-related factors. Fortunately, adverse effects and undesirable sequelae after Botox injections are temporary. Complications may be more serious in patients who have more severe rhytids (which require more Botox), have undergone previous facial plastic surgery (altered anatomy), and those who have preexisting neuromuscular disease. The physician can reduce complications by using proper injection techniques, appropriate regional Botox dosing, and by being conservative in the overall approach to Botox-mediated facial rejuvenation.

Relevant anatomy for botulinum toxin facial rejuvenation.
Over the last several years, Botox has become an integral treatment modality in the management of facial aging. Through selective chemical denervation, rhytids that are associated with hyperfunctioning muscles can be considerably softened or eliminated. Most practitioners rely on surface anatomy and landmarks to guide accurate needle insertion and Botox therapy. Therefore, a detailed appreciation of the underlying muscular anatomy is paramount in improving the practitioner's cosmetic results and the patients' overall satisfaction.
