Introduction
Tonsillectomy is one of the most common procedure in
Otorhinolaryngology, and it is recommended when the following standard
is met: more than seven episodes in the prior year, or more than five
episodes annually in the past 2 years, or more than three episode in the
past 3 years(1). Although tonsillectomy is considered a simple
procedure, how to further improve its safety, efficiency, painlessness
and operability is still a concern. The efficacy of different
tonsillectomy techniques is controversial.
HS uses ultrasonic waves to vibrate the knife head, vaporize the fluid
in the tissue, denature and coagulate the protein in the cell, and
produce hemostatic effect while cutting the tissue(2). Coblation uses
the formation of a plasma thin layer in a plasma radio frequency
electric field. The charged particles in the plasma thin layer are
accelerated to dissociate the molecular bonds in the tissue and form
carbohydrates and oxides. Under relatively low temperature conditions
(40℃-70℃) to achieve the purpose of ablation and coagulation(3).
The aim of this study is to comapre postoperative pain score and
postoperative bleeding loss of HS, coblation and CD tonsillectomy to
select the surgical technique with the least complications and to
explore the best tonsillectomy technique in adult in terms of operative
time, intraoperative bleeding loss, pseudomembrane growth and shedding
time, and necrosis depth of specimen.
