Total Thyroidectomy

In this clinical trial, the investigators are seeking to learn if a course of voice therapy, including neck massage, stretches and pain science education in addition to voice exercise and scar massage will effectively treatment patient complaints of swallowing or voice changes after total thyroidectomy as compared to voice exercise and scar massage alone. The main questions it aims to answer are: Will neck massage, stretches and pain science education reduce patient complaints of swallowing changes after total thyroidectomy? Will neck massage, stretches and pain science education reduce patient complaints of voice changes after total thyroidectomy? Will neck massage, stretches and pain science education reduce patient complaints of scar tethering and quality changes after total thyroidectomy? Will neck massage, stretches and pain science education improve quality of life after total thyroidectomy? Participants will: Participate in 4 visits with the participant's endocrine/laryngology surgeon. One prior and 3 after surgery for endoscopic evaluation and tests. Participate in 5 Speech-Language Pathology Sessions for intervention exercises and tests. One prior and 4 after surgery. Complete a journal of the participant's Home Exercise Practice

This is a prospective, single-blinded, randomized controlled trial to evaluate whether PTeye™ can reduce post-operative hypoparathyroidism (PH). The study will enroll consecutive patients undergoing total thyroidectomy in a teritary endocrine surgery unit in Hong Kong, randomizing them into receiving conventional surgery versus PTeye™-assisted surgery. Subjects will be assigned to the two groups before surgery. Subjects will be under medical care as in usual practice.
