Objective:
To evaluate the efficacy of CO2 laser cauterization with suspension microlaryngoscopy as a definitive surgical treatment for pediatric Congenital Pyriform Sinus Fistula (CPSF).
Material And Methods:
This is a cohort retrospective study. Thyroid function and cervical ultrasonography examinations were performed before operation. Enhanced magnetic resonance imaging (MRI) was performed on patients with a repeated infection (≥2 times) and/or if they had a prior open surgery. Patients were divided into two groups: the <8-year-old group and the ≥8-year-old group. The differences in the number of cauterization procedures between the two age groups and between the initial treatment and the retreatment groups were analyzed.
Results:
CO2 laser cauterizations with suspension microlaryngoscopy were performed for 104 CPSF patients. No complications occurred. Three patients had a recurrence in the follow-up. The number of surgical cauterization operations was fewer than 3 in 85.1% of the patients. There was no significant difference in the number of cauterizations among the different age groups or between the initial treatment and retreatment groups (P>0.05).
Conclusion:
CO2 laser cauterization with suspension microlaryngoscopy is a safe, effective, and minimally invasive approach to CPSF with optimal patient outcomes.
Type Of Study:
Treatment Study.
Level Of Evidence:
Level III.
