The laser ablation of thyroid nodules is performed in day hospital or day-surgery. The patient is placed under mild sedation (the same type of sedation used in an endoscopic examination). A local anesthetic is then applied, and one or two needles (depending on the size of the nodule) placed inside the nodule under ultrasound guidance.
A lobectomy of the thyroid gland A total thyroidectomy. Hemithyroidectomy — Entire isthmus is removed along with 1 lobe. Done in benign diseases of only 1 lobe. Subtotal thyroidectomy — Removal of majority of both lobes leaving behind 4-5 grams (equivalent to the size of a normal thyroid gland) of thyroid tissue on one or both sides—this used to be the most common operation for ...
An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]
Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
If the nodule is malignant or has indeterminate cytologic features, it may require surgery. [2] A thyroidectomy is a medium-risk surgery that can result in complications if not performed correctly. Problems with the voice, nerve or muscular damage, or bleeding from a lacerated blood vessel are rare but serious complications that may occur.
The procedure is similar to a thyroid biopsy, although instead of using a needle to remove cells from the nodule, a probe delivers heat to the interior of the nodule that effectively cauterizess the tissue. [medical citation needed] Over the course of 3-6 months, the nodule will continue to shrink, typically achieving a 50-80% reduction total size.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Regular monitoring mainly consists of watching for changes in nodule size and symptoms, and repeat ultrasonography or needle aspiration biopsy if the nodule grows. [8] For patients with benign thyroid adenomata, thyroid lobectomy and isthmusectomy is a sufficient surgical treatment.
