In clinical practice, for large thyroid nodules that cause compressive symptoms, such as difficulty swallowing, breathlessness, and hoarseness, thyroid nodule excision surgery can be performed. However, this surgery can have sequelae. First, if the excised thyroid tissue is too large, it can easily lead to reduced thyroid function, requiring lifelong supplementation with thyroid hormones for treatment. Secondly, due to the sensitive location of the thyroid gland, which is surrounded by various glands and nerves, injury during surgery can lead to complications such as seizures and hoarseness, which are considered post-surgical sequelae.
