[Piezoelectric ear surgery: a systematic review. German version].

Area of Science:

• Otolaryngology
• Surgical Technology

Background:

• Piezoelectric instrument (PEI) utilizes micro-oscillation and cavitation for bone removal in ear surgery.
• Comparison of PEI with traditional drills in otologic procedures.

Purpose of the Study:

• To review the advantages, disadvantages, and limitations of PEI in ear surgery.
• To compare PEI's efficacy and safety against conventional drilling techniques.

Main Methods:

• Systematic literature search of PubMed/MEDLINE and Google Scholar following PRISMA guidelines.
• Inclusion of studies on PEI in ear surgery, with a focus on those including a control group.

Main Results:

• 49 studies (2003-2022) covering 1162 ear operations were identified.
• Predominantly retrospective, uncontrolled studies (76%); only one prospective randomized controlled trial.
• PEI demonstrated safer, more precise bone removal near soft tissues versus drills.

Conclusions:

• Piezoelectric surgery is an innovative technique for temporal bone procedures.
• PEI offers enhanced safety and precision, particularly around delicate structures.
• Current limitations include slower bone removal speed and higher costs, hindering broader application.
