Ex vivo biomechanical evaluation of polyester and polyblend suture techniques to perform equine laryngoplasty.

Abstract: To validate the use of a polyblend tape suture in equine laryngoplasty (PL). Methods: Experimental study. Methods: Thirty-two cadaveric larynges. Methods: Each larynx was randomly assigned to 1 of 4 groups: PL with polyblend tape suture (TigerTape), without (TT) or with a cannula (TTC) in the muscular process of the arytenoid cartilage, and PL with polyester suture (Ethibond), without (EB) or with a cannula (EBC). Construct stiffness, total migration, creep, and drift values were measured after 3000 cycles. The specimens were then loaded to failure to assess their residual properties: load at failure, total energy, displacement, and 2 stiffness coefficients. Results: After cyclic testing, the total migration and creep were lower in TTC (6.36 ± 1.20 mm; 1.35 ± 0.38 mm/s) than in EB (11.12 ± 4.20 mm; 3.39 ± 2.68 mm/s) and in the TT constructs (11.26 ± 1.49 mm; 3.20 ± 0.54 mm/s); however, no difference was found with EBC (9.19 ± 3.18 mm; 2.14 ± 0.99). A correlation was found between total migration and creep (R = .85). The TTC constructs failed at higher loads (129.51 ± 33.84 N) than EB (93.16 ± 18.21 N) and EBC (81.72 ± 13.26 N) whereas the EB and EBC constructs were less stiff than TT and TTC (P < .001). Conclusions: Biomechanical properties were generally superior for the TTC constructs tested under cyclical loading. The TT and TTC constructs failed at a higher load than EB and EBC constructs. The cannula in TTC and EBC reduced the failure at the muscular process. Conclusions: These results provide evidence to support the in vivo evaluation of the polyblend tape suture with or without a cannula in the muscular process for laryngoplasty in horses.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research investigates biomechanical properties of various suture techniques used in performing equine laryngoplasty, claiming polyblend tape sutures, specifically with a cannula, exhibit superior properties under cyclical loading conditions.

Research Methodology

  • The investigation was an experimental study conducted on thirty-two cadaveric larynges, randomly split into four groups, each reflecting a unique combination of suture method:
    • PL with polyblend tape suture (TigerTape) with, and without a cannula,
    • PL with polyester suture (Ethibond), with and without a cannula.
  • Multiple metrics were recorded for each group, including construct stiffness, total migration, creep and drift values after 3,000 cycles. They were then pushed to failure to measure their residual properties, like load at failure, total energy, displacement, and stiffness coefficients.

Research Findings

  • Initial results showcased noticeably lower total migration and creep in polyblend sutures with a cannula (TTC) compared to Ethibond sutures and polyblend sutures without a cannula.
  • A close correlation between total migration and creep (R = .85) was observed, inferring a corresponding relationship.
  • TTC constructs endured higher failure loads compared to both Ethibond designs, whereas both Ethibond constructs were less stiff than their polyblend counterparts.

Conclusions

  • Through this evidence, the researchers reasoned that the biomechanical properties were generally superior for the TTC constructs when tested under cyclical loading.
  • All polyblend constructs were more resilient under higher loads than both Ethibond constructs.
  • The inclusion of a cannula in TTC and EBC sutures resulted in less failure at the muscular process.
  • These findings advocate for an in vivo evaluation of the polyblend sutures, both with and without a cannula, in the muscular process for equine laryngoplasty, suggesting their potential clinical advantages.
