Introduction And Aims:
There is no consensus on the optimal tonsillectomy technique in adult patients. The study aims to identify all studies comparing the outcomes of coblation versus bipolar diathermy in adult patients undergoing tonsillectomy.
Methods:
A systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Primary outcomes were hemorrhage and postoperative pain. Secondary outcome measures included return to theatre, analgesia, intraoperative bleeding, diet, tonsillar healing, and operation time. Fixed-effects modeling was used for the analysis.
Results:
Six studies were identified enrolling a total of 1824 patients. There were no significant differences in terms of reactionary hemorrhage (OR = 1.81, P = .51), delayed hemorrhage (OR = 0.72, P = .20), or postoperative pain (mean difference = -0.15, P = .45); however, there is a general trend favuring coblation. For secondary outcomes, no significant differences noted in terms of intraoperative bleeding, diet, and cases returning to theatre. Analgesia administration was either insignificant or higher in the coblation group. The coblation group had longer operation time and greater healing effect on tonsillar tissue.
Conclusions:
There were no significant differences in outcomes for coblation and bipolar diathermy for adult tonsillectomy patients in this systematic review and meta-analysis.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
