Background:
Postoperative sore throat (POST) is a common postoperative complication.
Complication:
Chewing gum can inhibit the growth of oral bacteria, cleanse, and lubricate the oral cavity, which can help reduce postoperative sore throat. We hypothesize that chewing gum before surgery could relieve POST.
Methods:
Patients planned to undergo total thyroidectomy under general anesthesia with tracheal intubation were randomized to swallow saliva twice or chew 1.4 g/2.8 g of gum for 2 minutes before surgery. A standard anesthesia protocol was performed. The numerical rating scale scores of POST at 1, 24, and 48 h after surgery were collected. The primary outcome was the incidence of moderate/severe POST (numerical rating scale score >3) within 48 h.
Results:
Data from 148 patients (control group, n = 50; 1.4 g group, n = 48; and 2.8 g group, n = 50) were included in the analysis. Within 48 h, there was a significant difference among the three groups in the incidence of moderate/severe POST (control group: 74% vs. 1.4 g group: 65% vs. 2.8 g group: 50%. P = 0.04). The 2.8 g group had less incidence of moderate/severe POST than the control group (Odds Ratio = 0.351 95% Confidence Interval: (0.152 and 0.814) P = 0.02).
Conclusion:
Chewing 2.8 g gum before total thyroidectomy can reduce the incidence of moderate/severe POST within 48 h after surgery.

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.
