==Surgery==
Surigical management of thyroid nodule is performed in case of non-diagnostic or suspicious biopsy, for removal of primary [[thyroid cancer]] or for [[thyroid cancer]] staging for [[radioactive]] ablation and [[serum]] [[thyroglobulin]] monitoring.  
Partially cystic nodules that repeatedly yield nondiagnostic aspirates need close observation or surgical excision. Surgery should be more strongly considered if the cytologically nondiagnostic nodule is solid.
 
If a cytology result is diagnostic of or suspicious for PTC, surgery is recommended 65
 
For those patients with subsequent recurrent symptomatic cystic fluid accumulation, surgical removal, generally by hemithyroidectomy, or percutaneous ethanol injection (PEI) are both reasonable strategies
 
Recurrent cystic thyroid nodules with benign cytology should be considered for surgical removal or PEI based on compressive symptoms and cosmetic concerns.

for patients with nodules diagnosed as differentiated thyroid carcinoma (DTC) by FNA during pregnancy, delaying surgery until after delivery does not affect outcome
 
Moosa M, Mazzaferri EL 1997 Outcome of differentiated thyroid cancer diagnosed in pregnant women. J Clin Endocrinol Metab 82:2862–2866.
 
A nodule with cytology indicating PTC discovered early in pregnancy should be monitored sonographically and if it grows substantially (as defined above) by 24 weeks gestation, surgery should be performed at that point. However, if it remains stable by midgestation or if it is diagnosed in the second half of pregnancy, surgery may be performed after delivery. In patients with more advanced disease, surgery in the second trimester is reasonable
 
The goals of thyroid surgery can include provision of a diagnosis after a nondiagnostic or indeterminate biopsy, removal of the thyroid cancer, staging, and preparation for radioactive ablation and serum Tg monitoring
 
==== Table ====
summary recommendation:
 
For patients with thyroid cancer >1 cm, the initial surgical procedure should be a near-total or total thyroidectomy unless there are contraindications to this surgery. Thyroid lobectomy alone may be sufficient treatment for small (<1 cm), low-risk, unifocal, intrathyroidal papillary carcinomas in the absence of prior head and neck irradiation or radiologically or clinically involved cervical nodal metastases


== Surgery==
Not all thyroid nodules require a surgical intervention, in fact surgical intervention goals for a thyroid nodule include:
* Provision of a diagnosis after a non-diagnostic or suspicious [[Biopsy forceps|biopsy]]
* Removal of the [[thyroid cancer]]
* [[Thyroid cancer]] staging for [[Radioactive iodine uptake|radioactive ablation]] and serum [[thyroglobulin]] monitoring

** Solid nodules
* If [[Molecular biology|molecular testing]] is unavailable and repeat [[Aspiration|aspirates]] continue to show atypical [[Cells (biology)|cells]]
* [[Cytology]] result is diagnostic of or suspicious for [[papillary thyroid cancer]]
* [[Toxic adenoma]]
* Features suggestive of but not definitive for [[papillary thyroid cancer]]
* [[Cytology]] diagnostic of [[malignancy]] (include [[papillary thyroid cancer]], [[medullary thyroid cancer]], [[thyroid]] [[lymphoma]], [[anaplastic thyroid cancer]], and [[metastatic]] [[thyroid cancer]])
* Large solid nodules with suspicious [[ultrasound]] findings
* If growth of the nodule (>20 percent in two dimensions on [[ultrasound]]) is detected during observation
* Recurrent [[symptomatic]] cysts with associated fluid accumulation
** Generally [[hemithyroidectomy]] or [[percutaneous]] [[ethanol]] [[Injection (medicine)|injection]]
** Decision should be made based on compressive [[symptoms]] and [[Cosmetic Surgery|cosmetic]] concerns

Overview

Surigical management of thyroid nodule is performed in case of non-diagnostic or suspicious biopsy, for removal of primary thyroid cancer or for thyroid cancer staging for radioactive ablation and serum thyroglobulin monitoring.

Surgery

Not all thyroid nodules require a surgical intervention, in fact surgical intervention goals for a thyroid nodule include:

Thyroid surgery definition terms

Term Definition

Hemithyroidectomy

Unilateral lobectomy, removing only half of the thyroid
Isthmusectomy Excising only the thyroid isthmus
Near-total thyroidectomy Removal of all grossly visible thyroid tissue, leaving only a small amount (<1 g) of tissue adjacent to the recurrent laryngeal nerve near the ligament of Berry
Total thyroidectomy Removal of all grossly visible thyroid tissue
Subtotal thyroidectomy Leaving >1 g of tissue with the posterior capsule on the uninvolved side, is an inappropriate operation for thyroid cancer

Diagnostic and curative surgical interventions

Indications:

Surgical procedure based on tumor status

Tumor criteria Tumor size Surgical procedure Note
Tumor without extrathyroidal extension and no lymph nodes <1 cm Thyroid lobectomy
Total thyroidectomy
Tumor without extra thyroidal extension and no lymph node 1 to 4 cm Thyroid lobectomy Based on:
  • Patient preference
  • Evidence of metastasis on imaging

Multifocal papillary microcarcinoma (fewer than five foci) Unilateral lobectomy and isthmectomy
Multifocal papillary microcarcinoma (more than five foci) Total thyroidectomy
Indeterminate or suspicious thyroid nodules unilateral lobectomy and

isthmectomy

  • Decision should be made based on the imaging suspicious

to whether perform a total thyroidectomy or a unilateral lobectomy

Total thyroidectomy
Indeterminate thyroid nodules and DTC Total thyroidectomy

Summary of surgical recommendations in thyroid nodules:

The best surgical options regarding thyroid nodules diagnosis are summarized in the table below:[1][2][3][4][5][6][7][8][9][10][11]

Surgical procedure Comment
Thyroid lobectomy Nondiagnostic biopsy, a biopsy suspicious for papillary cancer or suggestive of follicular neoplasm
  • For patients with an isolated indeterminate solitary nodule who prefer a more limited surgical procedure
  • Recommended as initial surgical approach
Total thyroidectomy Indicated in :
Surgery for a biopsy diagnostic for malignancy Near-total or total thyroidectomy if:
  • The primary thyroid carcinoma is >1 cm (156)
  • There are contralateral thyroid nodules present or regional or distant metastases are present
  • The patient has a personal history of radiation therapy to the head and neck
  • The patient has first-degree family history of differentiated thyroid carcinoma
  • Older age (>45 years) may also be a criterion for recommending near-total or total thyroidectomy even with tumors <1–1.5 cm, because of higher recurrence rates in this age group
Central-compartment (level VI) neck dissection Therapeutic central-compartment (level VI) neck dissection:
  • For patients with clinically involved central or lateral neck lymph nodes should accompany total thyroidectomy to provide clearance of disease from the central neck

Prophylactic central-compartment neck dissection (ipsilateral or bilateral):

Near-total or total thyroidectomy without prophylactic central neck dissection:

Lateral neck compartmental lymph node dissection
Tumors invade the upper aerodigestive tract Techniques ranging from shaving tumor off the trachea or esophagus for superficial invasion, to more aggressive techniques when the trachea is more deeply invaded (e.g., direct intraluminal invasion) including:
Comprehensive compartmental lateral and/or central neck dissection
  • Should be performed for patients with persistent or recurrent disease confined to the neck
  • Sparing uninvolved vital structures

Pregnancy and surgical resection of tumors[12]

Pregnant patients that are diagnosed with nodules as differentiated thyroid carcinoma by FNA, can utilize a delayed surgery, with the surgery scheduled for after the delivery. Researches have shown that delayed surgery will not decrease their response to therapy and their survival rate.

Exception should be made in these cases, which the surgery should be done during the pregnancy:
