Purpose:
Postoperative sore throat (POST) after thyroidectomy is a major concern.A roll is typically inserted under the shoulder to achieve head hypsokinesis and neck extension to better expose the surgical site during thyroid surgery. However, POST and impaired voice function have been attributed to neck overextension. This study aimed to explore the rational angle of head hypsokinesis that both reduced sore throat intensity and protects voice function after thyroid surgery.
Methods:
A total of 210 patients who underwent thyroidectomy were enrolled and randomized into high-tilt (Group H) and low-tilt angle groups (Group L). The primary outcome was the incidence of POST 6 h after surgery. Secondary outcomes included the severity of postoperative pharyngeal pain, voice function, swallowing pain, and coughing.
Results:
The incidence of POST 6 h after thyroidectomy was significantly lower in Group L than that in Group H. In addition, the intensity of postoperative sore throat and swallowing pain was more severe in Group H. A lower degree of head hypsokinesis in Group L prevented transient postoperative voice injury.
Conclusions:
A lower degree of head hypsokinesis effectively mitigated sore throat severity after thyroidectomy and improved postoperative voice function.
Register Information:
The trial was registered in the Chinese Clinical Trial Registry on 21 June 2022 (ChiCTR2200061329). The trial is registered at https://www.chictr.org.cn/showproj.html?proj=166254 .

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,...
