Effectiveness of Low-temperature plasma tonsillectomy for chronic tonsillitis. A protocol of systematic review and meta-analysis.

Aim: Recurrent episodes of chronic tonsillitis (CT) can affect a patient's quality of life, physical and mental health. Clinicians often perform surgeries to remove them. Traditional surgical methods are varied, despite their advantages. However, this remains controversial. This study aimed to examine both the safety and efficacy of low-temperature plasma tonsillectomy (LTPT) in treatment of chronic tonsillitis, which may provide a substitute for clinicians and compensate for the short supply of therapeutic procedures.

Methods And Analysis: This protocol is guided by the Preferred Reporting Items for Systematic.

Review And Meta-analysis: Protocols (PRISMA-P) and by the Cochrane Collaboration Handbook. We will formulate strict inclusion and exclusion criteria in English databases (PubMed, EMBASE, and Web of Science) and search literature in different clinical registration platforms (Cochrane Library). The including articles were evaluated by the Cochrane RCT evaluation criteria. The primary main endpoints will include the duration of operation, blood loss during surgery, time of formation and exfoliation of the pseudomembrane, average pain and duration post-operation, and time for normal diet. The Secondary endpoints will include complications of postoperative bleeding and infection. Stata 15.0 will be used for data analysis. Subgroup analysis, sensitivity analysis, and meta-regression were used to detect the sources of heterogeneity. Begg's Test will quantitatively detect publication bias quantitatively.

Ethics And Dissemination: The results of this meta-analysis and meta-regression will be disseminated through publication in a peer-reviewed journal. The data used in this meta-analysis will not contain individual patient data; therefore, ethical approval is not required.
