Usage of piezoelectric instruments in larynx surgery

Area of Science:

• Otolaryngology
• Surgical Technology

Background:

• Laryngeal surgeries require precise instrumentation for optimal outcomes.
• Minimally invasive techniques are increasingly preferred in head and neck surgery.

Purpose of the Study:

• To evaluate the usability and effectiveness of the piezoelectric knife in various larynx surgeries.
• To demonstrate the piezoelectric knife's capability for creating diverse incisions in laryngeal cartilages.

Main Methods:

• A study involving 35 patients undergoing procedures such as partial laryngectomy, thyroidectomy, and laryngeal lumen widening.
• Utilized a piezoelectric tool for precise cutting and resection of laryngeal cartilages.

Main Results:

• The piezoelectric knife enabled precise cutting of laryngeal cartilages, including the thyroid cartilage, in various shapes.
• The instrument demonstrated minimal loss and destruction of surrounding healthy tissues during procedures.

Conclusions:

• The piezoelectric knife is a valuable instrument for laryngeal cartilage operations, offering versatility through its exchangeable tips.
• Laryngeal surgery using the piezoelectric knife is safe, effective, and results in minimal local tissue destruction.
• This study highlights a novel application of piezoelectric tools in laryngeal surgery, suggesting a need for further investigation.
