Objectives: To compare the safety and effectiveness of tonsillectomy
with three different techniques. Design: A double-blinded randomized
prospective clinical trial Setting and Participants: Totally120 patients
with recurrent tonsillitis between April 2018 and April 2020 were
included. Main Outcome Measures: Operative time, intra and post
operative bleeding loss, pseudomembrane growth time, pseudomembrane
shedding time, postoperative pain, and necrosis depth of specimens were
compared of harmonic scalpel(HS), coblation and cold dissection(CD)
tonsillectomy. Results: The operative time and intraoperative bleeding
loss was significantly less in HS and coblation group than CD group(p
< 0.05). Pseudomembrane growth time and pseudomembrane
shedding time were significantly longer in the HS group compared with
the other groups(p < 0.05). The postoperative pain levels were
significantly higher on the first postoperative day in CD group(p
< 0.05), and significantly lower on the third and seventh
postoperative day in coblation group(p < 0.05). There was no
significant difference among three techniques in terms of postoperative
bleeding loss(p > 0.05). The deepest necrosis depth in
specimen was found in HS group(p > 0.05), while in CD
group, only edema was observed without necrosis. Conclusion: To compared
with HS and CD, coblation is a faster, safer and more painless technique
for tonsillectomy in adult.
