Summary
This summary is machine-generated.

Sharpness of rhinoplasty osteotomes degrades with use, with significant differences in initial sharpness and wear between manufacturers. Storz and Miltex osteotomes offered superior sharpness and cost-effectiveness, aiding surgeon instrument selection.

Area of Science:

  • Plastic Surgery
  • Biomedical Engineering
  • Surgical Instrumentation

Background:

  • Sharp osteotomes are crucial for effective rhinoplasty.
  • Variability in osteotome performance and cost-effectiveness is not well-documented.
  • Objective quantification of surgical tool sharpness is needed.

Purpose of the Study:

  • To develop a quantitative method for assessing osteotome sharpness using artificial bone.
  • To evaluate changes in osteotome sharpness after repeated use.
  • To compare the sharpness, durability, and cost-effectiveness of osteotomes from different manufacturers.

Main Methods:

  • A prospective surgical model using artificial bone wedges was employed.
  • Osteotome sharpness was measured by the load required to cut Prolene suture at baseline and after 1, 4, 7, and 10 uses.
  • Analysis of Variance (ANOVA) was used for manufacturer comparisons, and cost per use was calculated.

Main Results:

  • Significant differences in baseline sharpness were observed, with Storz being the sharpest.
  • Most osteotomes showed significant sharpness degradation over time, though NexEdge did not.
  • Storz osteotomes maintained superior sharpness throughout use, and Storz and Miltex demonstrated better cost-effectiveness.

Conclusions:

  • Osteotome sharpness and durability vary significantly between manufacturers.
  • Quantitative assessment and cost-effectiveness analysis can guide surgeons in selecting and maintaining surgical instruments.
  • The study provides objective data to inform choices regarding rhinoplasty osteotomes.
