This clinical trial aims to evaluate the effects of a menthol-infused cold water spray on thirst perception, dry mouth, nausea, and physiological parameters in patients after rhinoplasty. The intervention is expected to provide a refreshing sensation, alleviate discomfort associated with postoperative thirst and dryness, and contribute to improved patient comfort and recovery. Physiological parameters such as heart rate, blood pressure, and oxygen saturation will also be monitored to assess systemic effects.
