Impact of Travel Neck Pillow Use on Neck Comfort and Mobility After Thyroidectomy

Participants in the intervention group will receive a U-shaped travel neck pillow immediately after surgery upon arrival to the ward. The pillow will be used only during rest (supine or semi-Fowler's position) for the first 24 hours postoperatively and removed before mobilization begins. After removal, assessments will include cervical comfort using the Visual Analog Scale (VAS), pain scores during neck movements (flexion, rotation, lateral flexion-excluding extension) via VAS, the McGill Pain Questionnaire for pain localization and severity, and cervical range of motion using a universal goniometer. This intervention aims to evaluate the pillow's effectiveness in reducing neck pain, stiffness, and discomfort, and improving mobility after thyroidectomy.
