ABSTRACT
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.
