Clinical Report: Laryngoscope-Assisted Plasma Radiofrequency Ablation for CPSF

Overview

This study evaluates the safety and efficacy of a combined surgical approach for neonatal congenital pyriform sinus fistula (CPSF) with abscess. The results indicate that this technique may lead to different outcomes compared to simple drainage.

Background

Congenital pyriform sinus fistula (CPSF) is a rare anomaly that can present with significant complications, including neck abscesses in neonates. Traditional treatment methods often involve high surgical trauma and recurrence rates, as noted in previous studies. This study explores a minimally invasive technique that may improve outcomes for affected neonates.

Data Highlights

MetricCombined Surgery Group (n=14)Simple Drainage Group (n=7)
NFSS-8 Score11.87 ± 2.9415.29 ± 4.01
Vocal Cord Mobility92.86%57.14%
12-Month Recurrence Rate7.14%100%

Key Findings

  • The combined surgery group had a significantly lower NFSS-8 score compared to the simple drainage group (P = 0.019).
  • Normal vocal cord movement was more prevalent in the combined surgery group (92.86% vs. 57.14%, P = 0.043).
  • The 12-month recurrence rate was significantly lower in the combined surgery group (7.14% vs. 100%, P = 0.002).
  • There were no significant differences in blood loss or pain levels between the two groups.
  • The combined surgery group experienced a longer operating time (P < 0.001).

Clinical Implications

The findings indicate that combining neck abscess incision and drainage with plasma radiofrequency ablation may provide a treatment option for neonatal CPSF. Further research is needed to validate these findings.

Conclusion

The study supports the use of a minimally invasive technique for treating CPSF in neonates. Further research is warranted to validate these findings in larger cohorts.
