Voice analysis before and after thyroid surgery

Voice change after thyroidectomy is one of the most common complaints and have a significant impact on patients quality of life. Postoperative voice change may occur due to vocal cord paralysis after recurrent laryngeal nerve injury during surgery, but recently, voice change without nerve injury is getting a lot of attention, and many studies are being performed on it. Pre-operative voice evaluation is necessary for the purpose of detecting pre-existing voice abnormalities and securing a baseline data to counsel patients about their impaired voice or provide appropriate postoperative voice therapy. Post-operative voice evaluation is also important to accurately evaluate voice abnormalities and provide appropriate treatment. Techniques of voice evaluation vary from subjective measurement using questionnaires to professional analysis including acoustic and aerodynamic studies. Among various methods, it is important to properly select and implement a method available for the conditions of each institution, and refer to a specialist if it is difficult to perform professional analysis and treatment.
