1. initial evaluation of thyroid disease
Thyroidectomy is most commonly performed to treat thyroid cancer, an overactive thyroid gland, or a benign goitre causing pressure symptoms. Asymptomatic benign thyroid nodules are very common being present in over 50% of the population and most do to need any treatment. The incidence of thyroid cancer is rising rapidly, mostly due to increased detection of small papillary microcarcinomas on imaging studies. These are all curable so there has not bee any increase in death rates form thyroid cancer.
The AAES recommendations for initial evaluation emphasis the need for history and examination, voice assessment, and assessment of hormonal status.
Comments: Most thyroid problems do not require surgery hence the need for careful evaluation to avoid unnecessary operations as well as to reduce the risk of complications. All patients undergo a comprehensive evaluation with personal and family history as well as examination of the neck and thyroid gland. Voice assessment is now performed using the Voice Handicap Index (VHI), a validated assessment tool for any pre-existing damage to the nerves controlling the voice box. An abnormal result will require a subsequent laryngoscopy but most patients can now avoid that invasive investigation.
