Purpose Of Review:
The use of piezoelectric instrumentation is increasingly recognized as an alternative to traditional bone-cutting techniques across a wide array of surgeries. Here, we provide an overview of the technique, including device principles, benefits, and drawbacks. We also review its use in craniofacial surgery.
Recent Findings:
Piezoelectric surgery is a minimally invasive bone-cutting system with lower risk of damage to surrounding soft tissue structures. Indications for its use are rapidly expanding across multiple fields, including craniofacial surgery. To date, piezosurgical techniques have been most widely adopted and studied in the contexts of rhinoplasty, orthognathic surgery, and cranioplasty in craniosynostosis. Piezosurgery can facilitate more precise and consistent osteotomies while decreasing morbidities associated with traditional osteotomy techniques. Primary limitations include cost and concerns regarding increased operative times secondary to operator learning curves and decreased cutting efficiency.
Summary:
Piezoelectric surgery represents an alternative to traditional bone-cutting modalities to improve precision, consistency, and safety of osteotomies. Further research is needed to better understand the efficacy of the technique as well as potential for additional applications.
