Advantages of Cold-knife Dissection with Adjunctive Suction Cauterization Adenotonsillectomy: A Useful and Safe Surgical Technique for Pediatric Patients / 대한이비인후과학회지

ABSTRACT

Background and Objectives@#To introduce cold-knife dissection with adjunctive suction cauterization (CDASC) technique for pediatric adenotonsillectomy and to evaluate the advantages of this technique through short and long-term follow-up results.Subjects and Method Enrolled in the study were 492 subjects with a mean age of 6.5 years, who underwent adenotonsillectomy via the CDASC technique. Surgical outcomes were evaluated through the postoperative bleeding rate, days of normal diet (as a measure of pain), and improvement of obstructive symptoms at regular follow-up visits. Intraoral photography and lateral neck radiography were analyzed for long-term surgical outcomes. @*Results@#None of the enrolled patients revisited the hospital due to hemorrhage, indicating 0% immediate and delayed postoperative bleeding with this surgical technique. Most of the patients showed normal diet consumption and activity within 3 days. Postoperative intraoral photography after 6 and 12 months were graded as normal (grade 0) in 77.5% and 79.7% of the enrolled patients, respectively. Postoperative adenoid to nasopharyngeal ratios were significantly reduced (p<0.05) and no recurrence of snoring and adenoid regrowth were demonstrated during the follow-up period of 12 months. @*Conclusion@#Our CDASC technique seems to have several advantages including less postoperative pain, no postoperative bleeding, less scarring, and no recurrence of preoperative symptoms. We suggest that our CDASC technique is a very useful, safe, and effective method of surgery for pediatric adenotonsillectomy.
