Piezoelectric instrumentation (PEI) in rhinoplasty offers enhanced precision for bony vault and lateral wall management. This technique, utilizing ultrasonic rhinosculpture, resulted in superior surgical outcomes with minimal revisions in 185 clinical cases.
Area of Science:
- Plastic Surgery
- Otolaryngology
- Facial Plastic Surgery
Background:
- Traditional rhinoplasty relies on mechanical instruments for bony vault and lateral wall manipulation.
- These instruments, while refined, present challenges in soft tissue preservation and precision.
Purpose of the Study:
- To present the evolution of a surgical technique using piezoelectric instrumentation (PEI) in rhinoplasty.
- To evaluate the outcomes of 185 clinical cases performed over 19 months using PEI.
Main Methods:
- A study combining cadaver dissections and 185 clinical rhinoplasty cases utilizing PEI.
- Documentation of the evolution of the authors' clinical technique and operative sequence.
Main Results:
- PEI was used in 185 cases (82 primary, 103 secondary).
- Ultrasonic rhinosculpture (URS) was employed in 95 patients for bony vault contouring without osteotomies.
- A low revision rate of 6% (11 cases) was observed, with no instances of bone asymmetry or irregularity requiring revision.
Conclusions:
- PEI provides a more precise approach to rhinoplasty, justifying its adoption for improved surgical execution and outcomes.
- Extensive subperiosteal dissection with PEI allows for accurate diagnosis and safe contouring of bony deformities, achieving desired narrowing and symmetry.
- PEI enhances control during osteotomies and bone mobilization, leading to predictable and superior results in the upper third of rhinoplasty.
